## [0.10.1] - 2017-04-19
Tag name: v0.10.1
## Added
* Documentation for the BigchainDB settings `wsserver.host` and `wsserver.port`. [Pull Request #1408](https://github.com/bigchaindb/bigchaindb/pull/1408)
## Fixed
* Fixed `Dockerfile`, which was failing to build. It now starts `FROM python:3.6` (instead of `FROM ubuntu:xenial`). [Pull Request #1410](https://github.com/bigchaindb/bigchaindb/pull/1410)
* Fixed the `Makefile` so that `release` depends on `dist`. [Pull Request #1405](https://github.com/bigchaindb/bigchaindb/pull/1405)
## [0.10.0] - 2017-04-18
Tag name: v0.10.0
### Added
* Improved logging. Added logging to file. Added `--log-level` option to `bigchaindb start` command. Added new logging configuration settings. Pull Requests

[#1299](https://github.com/bigchaindb/bigchaindb/pull/1299) and
[#1348](https://github.com/bigchaindb/bigchaindb/pull/1348)
### Changed
* The main BigchainDB Dockerfile (and its generated Docker image) now contains only BigchainDB Server. (It used to contain both BigchainDB Server and RethinkDB.) You must now run MongoDB or RethinkDB in a separate Docker container. [Pull Request #1174](https://github.com/bigchaindb/bigchaindb/pull/1174)
* Made separate schemas for CREATE and TRANSFER transactions. [Pull Request #1257](https://github.com/bigchaindb/bigchaindb/pull/1257)
* When signing transactions with threshold conditions, we now sign all subconditions for a public key. [Pull Request #1294](https://github.com/bigchaindb/bigchaindb/pull/1294)
* Many changes to the voting-related code, including how we validate votes and prevent duplicate votes by the same node. Pull Requests [#1215](https://github.com/bigchaindb/bigchaindb/pull/1215) and [#1258](https://github.com/bigchaindb/bigchaindb/pull/1258)
### Removed
* Removed the `bigchaindb load` command. Pull Requests
[#1261](https://github.com/bigchaindb/bigchaindb/pull/1261),
[#1273](https://github.com/bigchaindb/bigchaindb/pull/1273) and
[#1301](https://github.com/bigchaindb/bigchaindb/pull/1301)
* Removed old `/speed-tests` and `/benchmarking-tests` directories. [Pull Request #1359](https://github.com/bigchaindb/bigchaindb/pull/1359)
### Fixed
* Fixed the URL of the BigchainDB docs returned by the HTTP API. [Pull Request #1178](https://github.com/bigchaindb/bigchaindb/pull/1178)
* Fixed the MongoDB changefeed: it wasn't reporting update operations. [Pull Request #1193](https://github.com/bigchaindb/bigchaindb/pull/1193)
* Fixed the block-creation process: it wasn't checking if the transaction was previously included in:
* a valid block. [Pull Request #1208](https://github.com/bigchaindb/bigchaindb/pull/1208)
* the block-under-construction. Pull Requests [#1237](https://github.com/bigchaindb/bigchaindb/issues/1237) and [#1377](https://github.com/bigchaindb/bigchaindb/issues/1377)

### Notes
* MongoDB is now the recommended database backend (not RethinkDB).
* There are some initial docs about how to deploy a BigchainDB node on Kubernetes. It's work in progress.

Someone will then merge your branch or suggest changes. If we suggest changes, you won't have to open a new pull request, you can just push new code to the same branch (on `origin`) as you did before creating the pull request.
### Tip: Upgrading All BigchainDB Dependencies
Over time, your versions of the Python packages used by BigchainDB will get out of date. You can upgrade them using:
```text
pip install --upgrade -e .[dev]

# Terminology
There is some specialized terminology associated with BigchainDB. To get started, you should at least know what what we mean by a BigchainDB *node*, *cluster* and *consortium*.
There is some specialized terminology associated with BigchainDB. To get started, you should at least know the following:
## Node
## BigchainDB Node
A **BigchainDB node** is a machine or set of closely-linked machines running RethinkDB/MongoDB Server, BigchainDB Server, and related software. (A "machine" might be a bare-metal server, a virtual machine or a container.) Each node is controlled by one person or organization.

## Cluster
## BigchainDB Cluster
A set of BigchainDB nodes can connect to each other to form a **cluster**. Each node in the cluster runs the same software. A cluster contains one logical RethinkDB datastore. A cluster may have additional machines to do things such as cluster monitoring.

## Consortium
## BigchainDB Consortium
The people and organizations that run the nodes in a cluster belong to a **consortium** (i.e. another organization). A consortium must have some sort of governance structure to make decisions. If a cluster is run by a single company, then the "consortium" is just that company.

## Create an AWS Access Key
The next thing you'll need is an AWS access key. If you don't have one, you can create one using the [instructions in the AWS documentation](http://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSGettingStartedGuide/AWSCredentials.html). You should get an access key ID (e.g. AKIAIOSFODNN7EXAMPLE) and a secret access key (e.g. wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY).
The next thing you'll need is AWS access keys (access key ID and secret access key). If you don't have those, see [the AWS documentation about access keys](https://docs.aws.amazon.com/general/latest/gr/aws-sec-cred-types.html#access-keys-and-secret-access-keys).
You should also pick a default AWS region name (e.g. `eu-central-1`). That's where your cluster will run. The AWS documentation has [a list of them](http://docs.aws.amazon.com/general/latest/gr/rande.html#ec2_region).

# Run BigchainDB with Docker On Mac
**NOT for Production Use**
Those developing on Mac can follow this document to run BigchainDB in docker
containers for a quick dev setup.
Running BigchainDB on Mac (Docker or otherwise) is not officially supported.
Support is very much limited as there are certain things that work differently
in Docker for Mac than Docker for other platforms.
Also, we do not use mac for our development and testing. :)
This page may not be up to date with various settings and docker updates at
all the times.
These steps work as of this writing (2017.Mar.09) and might break in the
future with updates to Docker for mac.
Community contribution to make BigchainDB run on Docker for Mac will always be
welcome.
## Prerequisite
Install Docker for Mac.
## (Optional) For a clean start
1. Stop all BigchainDB and RethinkDB/MongoDB containers.
2. Delete all BigchainDB docker images.
3. Delete the ~/bigchaindb_docker folder.
## Pull the images
Pull the bigchaindb and other required docker images from docker hub.
```text
docker pull bigchaindb/bigchaindb:master
docker pull [rethinkdb:2.3|mongo:3.4.1]
```
## Create the BigchainDB configuration file on Mac
```text
docker run \
--rm \
--volume $HOME/bigchaindb_docker:/data \
bigchaindb/bigchaindb:master \
-y configure \
[mongodb|rethinkdb]
```
To ensure that BigchainDB connects to the backend database bound to the virtual
interface `172.17.0.1`, you must edit the BigchainDB configuration file
(`~/bigchaindb_docker/.bigchaindb`) and change database.host from `localhost`
to `172.17.0.1`.
## Run the backend database on Mac
From v0.9 onwards, you can run RethinkDB or MongoDB.
We use the virtual interface created by the Docker daemon to allow
communication between the BigchainDB and database containers.
It has an IP address of 172.17.0.1 by default.
You can also use docker host networking or bind to your primary (eth)
interface, if needed.
### For RethinkDB backend
```text
docker run \
--name=rethinkdb \
--publish=28015:28015 \
--publish=8080:8080 \
--restart=always \
--volume $HOME/bigchaindb_docker:/data \
rethinkdb:2.3
```
### For MongoDB backend
```text
docker run \
--name=mongodb \
--publish=27017:27017 \
--restart=always \
--volume=$HOME/bigchaindb_docker/db:/data/db \
--volume=$HOME/bigchaindb_docker/configdb:/data/configdb \
mongo:3.4.1 --replSet=bigchain-rs
```
### Run BigchainDB on Mac
```text
docker run \
--name=bigchaindb \
--publish=9984:9984 \
--restart=always \
--volume=$HOME/bigchaindb_docker:/data \

# Example RethinkDB Storage Setups
## Example Amazon EC2 Setups
We have some scripts for [deploying a _test_ BigchainDB cluster on AWS](../clusters-feds/aws-testing-cluster.html). Those scripts include command sequences to set up storage for RethinkDB.
In particular, look in the file [/deploy-cluster-aws/fabfile.py](https://github.com/bigchaindb/bigchaindb/blob/master/deploy-cluster-aws/fabfile.py), under `def prep_rethinkdb_storage(USING_EBS)`. Note that there are two cases:
1. **Using EBS ([Amazon Elastic Block Store](https://aws.amazon.com/ebs/)).** This is always an option, and for some instance types ("EBS-only"), it's the only option.
2. **Using an "instance store" volume provided with an Amazon EC2 instance.** Note that our scripts only use one of the (possibly many) volumes in the instance store.
There's some explanation of the steps in the [Amazon EC2 documentation about making an Amazon EBS volume available for use](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-using-volumes.html).
You shouldn't use an EC2 "instance store" to store RethinkDB data for a production node, because it's not replicated and it's only intended for temporary, ephemeral data. If the associated instance crashes, is stopped, or is terminated, the data in the instance store is lost forever. Amazon EBS storage is replicated, has incremental snapshots, and is low-latency.
## Example Using Amazon EFS

## Other Examples?

Maybe RAID, ZFS, ... (over EBS volumes, i.e. a DIY Amazon EFS)

Assuming you aren't exposing the RethinkDB web interface on port 8080 (or any other port, because [there are more secure ways to access it](https://www.rethinkdb.com/docs/security/#binding-the-web-interface-port)), there are only three ports that should expect unsolicited inbound traffic:
1. **Port 22** can expect inbound SSH (TCP) traffic from the node administrator (i.e. a small set of IP addresses).
2. **Port 9984** can expect inbound HTTP (TCP) traffic from BigchainDB clients sending transactions to the BigchainDB HTTP API.
3. If you're using RethinkDB, **Port 29015** can expect inbound TCP traffic from other RethinkDB nodes in the RethinkDB cluster (for RethinkDB intracluster communications).

You may want to have Gunicorn and the reverse proxy running on different servers, so that both can listen on port 9984. That would also help isolate the effects of a denial-of-service attack.
## Port 9985
Port 9985 is the default port for the [BigchainDB WebSocket Event Stream API](../websocket-event-stream-api.html).
## Port 28015
Port 28015 is the default port used by RethinkDB client driver connections (TCP). If your BigchainDB node is just one server, then Port 28015 only needs to listen on localhost, because all the client drivers will be running on localhost. Port 28015 doesn't need to accept inbound traffic from the outside world.

# Backing Up & Restoring Data
# Backing Up and Restoring Data
There are several ways to backup and restore the data in a BigchainDB cluster.
This page was written when BigchainDB only worked with RethinkDB, so its focus is on RethinkDB-based backup. BigchainDB now supports MongoDB as a backend database and we recommend that you use MongoDB in production. Nevertheless, some of the following backup ideas are still relevant regardless of the backend database being used, so we moved this page to the Appendices.

# Production Node Requirements
# RethinkDB Requirements
Note: This section will be broken apart into several pages, e.g. NTP requirements, RethinkDB requirements, BigchainDB requirements, etc. and those pages will add more details.
[The RethinkDB documentation](https://rethinkdb.com/docs/) should be your first source of information about its requirements. This page serves mostly to document some of its more obscure requirements.
## OS Requirements
* RethinkDB Server [will run on any modern OS](https://www.rethinkdb.com/docs/install/). Note that the Fedora package isn't officially supported. Also, official support for Windows is fairly recent ([April 2016](https://rethinkdb.com/blog/2.3-release/)).
* BigchainDB Server requires Python 3.4+ and Python 3.4+ [will run on any modern OS](https://docs.python.org/3.4/using/index.html).
* BigchaindB Server uses the Python `multiprocessing` package and [some functionality in the `multiprocessing` package doesn't work on OS X](https://docs.python.org/3.4/library/multiprocessing.html#multiprocessing.Queue.qsize). You can still use Mac OS X if you use Docker or a virtual machine.
The BigchainDB core dev team uses recent LTS versions of Ubuntu and recent versions of Fedora.
We don't test BigchainDB on Windows or Mac OS X, but you can try.
* If you run into problems on Windows, then you may want to try using Vagrant. One of our community members ([@Mec-Is](https://github.com/Mec-iS)) wrote [a page about how to install BigchainDB on a VM with Vagrant](https://gist.github.com/Mec-iS/b84758397f1b21f21700).
* If you have Mac OS X and want to experiment with BigchainDB, then you could do that [using Docker](../appendices/run-with-docker.html).
RethinkDB Server [will run on any modern OS](https://www.rethinkdb.com/docs/install/). Note that the Fedora package isn't officially supported. Also, official support for Windows is fairly recent ([April 2016](https://rethinkdb.com/blog/2.3-release/)).

As for the read & write rates, what do you expect those to be for your situation? It's not enough for the storage system alone to handle those rates: the interconnects between the nodes must also be able to handle them.

* If you have an N-node RethinkDB cluster and 1) you want to use it to store an amount of data D (unique records, before replication), 2) you want the replication factor to be R (all tables), and 3) you want N shards (all tables), then each BigchainDB node must have storage space of at least R×D/N.
* RethinkDB tables can have [at most 64 shards](https://rethinkdb.com/limitations/). What does that imply? Suppose you only have one table, with 64 shards. How big could that table be? It depends on how much data can be stored in each node. If the maximum amount of data that a node can store is d, then the biggest-possible shard is d, and the biggest-possible table size is 64 times that. (All shard replicas would have to be stored on other nodes beyond the initial 64.) If there are two tables, the second table could also have 64 shards, stored on 64 other maxed-out nodes, so the total amount of unique data in the database would be (64 shards/table)×(2 tables)×d. In general, if you have T tables, the maximum amount of unique data that can be stored in the database (i.e. the amount of data before replication) is 64×T×d.
* When you set up storage for your RethinkDB data, you may have to select a filesystem. (Sometimes, the filesystem is already decided by the choice of storage.) We recommend using a filesystem that supports direct I/O (Input/Output). Many compressed or encrypted file systems don't support direct I/O. The ext4 filesystem supports direct I/O (but be careful: if you enable the data=journal mode, then direct I/O support will be disabled; the default is data=ordered). If your chosen filesystem supports direct I/O and you're using Linux, then you don't need to do anything to request or enable direct I/O. RethinkDB does that.
<p style="background-color: lightgrey;">What is direct I/O? It allows RethinkDB to write directly to the storage device (or use its own in-memory caching mechanisms), rather than relying on the operating system's file read and write caching mechanisms. (If you're using Linux, a write-to-file normally writes to the in-memory Page Cache first; only later does that Page Cache get flushed to disk. The Page Cache is also used when reading files.)</p>
* RethinkDB stores its data in a specific directory. You can tell RethinkDB _which_ directory using the RethinkDB config file, as explained below. In this documentation, we assume the directory is `/data`. If you set up a separate device (partition, RAID array, or logical volume) to store the RethinkDB data, then mount that device on `/data`.

First Node or Bootstrap Node Setup
==================================
This document is a work in progress and will evolve over time to include
security, websocket and other settings.
Step 1: Set Up the Cluster
--------------------------
.. code:: bash
az group create --name bdb-test-cluster-0 --location westeurope --debug --output json
ssh-keygen -t rsa -C "k8s-bdb-test-cluster-0" -f ~/.ssh/k8s-bdb-test-cluster-0
az acs create --name k8s-bdb-test-cluster-0 \
--resource-group bdb-test-cluster-0 \
--master-count 3 \
--agent-count 2 \
--admin-username ubuntu \
--agent-vm-size Standard_D2_v2 \
--dns-prefix k8s-bdb-test-cluster-0 \
--ssh-key-value ~/.ssh/k8s-bdb-test-cluster-0.pub \
--orchestrator-type kubernetes \
--debug --output json
az acs kubernetes get-credentials \
--resource-group bdb-test-cluster-0 \
--name k8s-bdb-test-cluster-0 \
--debug --output json
echo -e "Host k8s-bdb-test-cluster-0.westeurope.cloudapp.azure.com\n ForwardAgent yes" >> ~/.ssh/config
Step 2: Connect to the Cluster UI - (optional)
----------------------------------------------
* Get the kubectl context for this cluster using ``kubectl config view``.
* For the above commands, the context would be ``k8s-bdb-test-cluster-0``.
.. code:: bash
kubectl --context k8s-bdb-test-cluster-0 proxy -p 8001
Step 3. Configure the Cluster
-----------------------------
* Use the ConfigMap in ``configuration/config-map.yaml`` file for configuring
the cluster.
* Log in the the MongoDB Cloud Manager and select the group that will monitor
and backup this cluster from the dropdown box.
* Go to Settings, Group Settings and copy the ``Agent Api Key``.
* Replace the ``<api key here>`` field with this key.
* Since this is the first node of the cluster, ensure that the ``data.fqdn``
field has the value ``mdb-instance-0``.
* We only support the value ``all`` in the ``data.allowed-hosts`` field for now.
* Create the ConfigMap
.. code:: bash
kubectl --context k8s-bdb-test-cluster-0 apply -f configuration/config-map.yaml
Step 4. Start the NGINX Service
-------------------------------
* This will will give us a public IP for the cluster.
* Once you complete this step, you might need to wait up to 10 mins for the
public IP to be assigned.
* You have the option to use vanilla NGINX or an OpenResty NGINX integrated
with 3scale API Gateway.
Step 4.1. Vanilla NGINX
^^^^^^^^^^^^^^^^^^^^^^^
* This configuration is located in the file ``nginx/nginx-svc.yaml``.
* Since this is the first node, rename ``metadata.name`` and ``metadata.labels.name``
to ``ngx-instance-0``, and ``spec.selector.app`` to ``ngx-instance-0-dep``.
* Start the Kubernetes Service:
.. code:: bash
kubectl --context k8s-bdb-test-cluster-0 apply -f nginx/nginx-svc.yaml
Step 4.2. OpenResty NGINX + 3scale
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
* You have to enable HTTPS for this one and will need an HTTPS certificate
for your domain
* Assuming that the public key chain is named ``cert.pem`` and private key is
``cert.key``, run the following commands to encode the certificates into
single continuous string that can be embedded in yaml.
.. code:: bash
cat cert.pem | base64 -w 0 > cert.pem.b64
cat cert.key | base64 -w 0 > cert.key.b64
* Copy the contents of ``cert.pem.b64`` in the ``cert.pem`` field, and the
contents of ``cert.key.b64`` in the ``cert.key`` field in the file
``nginx-3scale/nginx-3scale-secret.yaml``
* Create the Kubernetes Secret:
.. code:: bash
kubectl --context k8s-bdb-test-cluster-0 apply -f nginx-3scale/nginx-3scale-secret.yaml
* Since this is the first node, rename ``metadata.name`` and ``metadata.labels.name``
to ``ngx-instance-0``, and ``spec.selector.app`` to ``ngx-instance-0-dep`` in
``nginx-3scale/nginx-3scale-svc.yaml`` file.
* Start the Kubernetes Service:
.. code:: bash
kubectl --context k8s-bdb-test-cluster-0 apply -f nginx-3scale/nginx-3scale-svc.yaml
Step 5. Assign DNS Name to the NGINX Public IP
----------------------------------------------
* The following command can help you find out if the nginx service strated above
has been assigned a public IP or external IP address:
.. code:: bash
kubectl --context k8s-bdb-test-cluster-0 get svc -w
* Once a public IP is assigned, you can log in to the Azure portal and map it to
a DNS name.
* We usually start with bdb-test-cluster-0, bdb-test-cluster-1 and so on.
* Let us assume that we assigned the unique name of ``bdb-test-cluster-0`` here.
Step 6. Start the Mongo Kubernetes Service
------------------------------------------
* Change ``metadata.name`` and ``metadata.labels.name`` to
``mdb-instance-0``, and ``spec.selector.app`` to ``mdb-instance-0-ss``.
.. code:: bash
kubectl --context k8s-bdb-test-cluster-0 apply -f mongodb/mongo-svc.yaml
Step 7. Start the BigchainDB Kubernetes Service
-----------------------------------------------
* Change ``metadata.name`` and ``metadata.labels.name`` to
``bdb-instance-0``, and ``spec.selector.app`` to ``bdb-instance-0-dep``.
.. code:: bash
kubectl --context k8s-bdb-test-cluster-0 apply -f bigchaindb/bigchaindb-svc.yaml
Step 8. Start the NGINX Kubernetes Deployment
---------------------------------------------
* As in step 4, you have the option to use vanilla NGINX or an OpenResty NGINX
integrated with 3scale API Gateway.
Step 8.1. Vanilla NGINX
^^^^^^^^^^^^^^^^^^^^^^^
* This configuration is located in the file ``nginx/nginx-dep.yaml``.
* Since this is the first node, change the ``metadata.name`` and
``spec.template.metadata.labels.app`` to ``ngx-instance-0-dep``.
* Set ``MONGODB_BACKEND_HOST`` env var to
``mdb-instance-0.default.svc.cluster.local``.
* Set ``BIGCHAINDB_BACKEND_HOST`` env var to
``bdb-instance-0.default.svc.cluster.local``.
* Set ``MONGODB_FRONTEND_PORT`` to
``$(NGX_INSTANCE_0_SERVICE_PORT_NGX_PUBLIC_MDB_PORT)``.
* Set ``BIGCHAINDB_FRONTEND_PORT`` to
``$(NGX_INSTANCE_0_SERVICE_PORT_NGX_PUBLIC_BDB_PORT)``.
.. code:: bash
kubectl --context k8s-bdb-test-cluster-0 apply -f nginx/nginx-dep.yaml
Step 8.2. OpenResty NGINX + 3scale
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
* This configuration is located in the file
``nginx-3scale/nginx-3scale-dep.yaml``.
* Since this is the first node, change the metadata.name and
spec.template.metadata.labels.app to ``ngx-instance-0-dep``.
* Set ``MONGODB_BACKEND_HOST`` env var to
``mdb-instance-0.default.svc.cluster.local``.
* Set ``BIGCHAINDB_BACKEND_HOST`` env var to
``bdb-instance-0.default.svc.cluster.local``.
* Set ``MONGODB_FRONTEND_PORT`` to
``$(NGX_INSTANCE_0_SERVICE_PORT_NGX_PUBLIC_MDB_PORT)``.
* Set ``BIGCHAINDB_FRONTEND_PORT`` to
``$(NGX_INSTANCE_0_SERVICE_PORT_NGX_PUBLIC_BDB_PORT)``.
* Also, replace the placeholder strings for the env vars with the values
obtained from 3scale. You will need the Secret Token, Service ID, Version Header
and Provider Key from 3scale.
* The ``THREESCALE_FRONTEND_API_DNS_NAME`` will be DNS name registered for your
HTTPS certificate.
* You can set the ``THREESCALE_UPSTREAM_API_PORT`` to any port other than 9984,
9985, 443, 8888 and 27017. We usually use port ``9999``.
.. code:: bash
kubectl --context k8s-bdb-test-cluster-0 apply -f nginx-3scale/nginx-3scale-dep.yaml
Step 9. Create a Kubernetes Storage Class for MongoDB
-----------------------------------------------------
.. code:: bash
kubectl --context k8s-bdb-test-cluster-0 apply -f mongodb/mongo-sc.yaml
Step 10. Create a Kubernetes PersistentVolumeClaim
--------------------------------------------------
.. code:: bash
kubectl --context k8s-bdb-test-cluster-0 apply -f mongodb/mongo-pvc.yaml
Step 11. Start a Kubernetes StatefulSet for MongoDB
---------------------------------------------------
* Change ``spec.serviceName`` to ``mdb-instance-0``.
* Change the ``metadata.name``, ``template.metadata.name`` and
``template.metadata.labels.app`` to ``mdb-instance-0-ss``.
* It might take up to 10 minutes for the disks to be created and attached to
the pod.
* The UI might show that the pod has errored with the
message "timeout expired waiting for volumes to attach/mount".
* Use the CLI below to check the status of the pod in this case,
instead of the UI. This happens due to a bug in Azure ACS.
.. code:: bash
kubectl --context k8s-bdb-test-cluster-0 apply -f mongodb/mongo-ss.yaml
* You can check the status of the pod using the command:
.. code:: bash
kubectl --context k8s-bdb-test-cluster-0 get po -w
Step 12. Start a Kubernetes Deployment for Bigchaindb
-----------------------------------------------------
* Change both ``metadata.name`` and ``spec.template.metadata.labels.app``
to ``bdb-instance-0-dep``.
* Set ``BIGCHAINDB_DATABASE_HOST`` to ``mdb-instance-0``.
* Set the appropriate ``BIGCHAINDB_KEYPAIR_PUBLIC``,
``BIGCHAINDB_KEYPAIR_PRIVATE`` values.
* One way to generate BigchainDB keypair is to run a Python shell with
the command
``from bigchaindb_driver import crypto; crypto.generate_keypair()``.
.. code:: bash
kubectl --context k8s-bdb-test-cluster-0 apply -f bigchaindb/bigchaindb-dep.yaml
Step 13. Start a Kubernetes Deployment for MongoDB Monitoring Agent
-------------------------------------------------------------------
* Change both metadata.name and spec.template.metadata.labels.app to
``mdb-mon-instance-0-dep``.
.. code:: bash
kubectl --context k8s-bdb-test-cluster-0 apply -f mongodb-monitoring-agent/mongo-mon-dep.yaml
* Get the pod name and check its logs:
.. code:: bash
kubectl --context k8s-bdb-test-cluster-0 get po
kubectl --context k8s-bdb-test-cluster-0 logs -f <pod name>
Step 14. Configure MongoDB Cloud Manager for Monitoring
-------------------------------------------------------
* Open `MongoDB Cloud Manager <https://cloud.mongodb.com>`_.
* Click ``Login`` under ``MongoDB Cloud Manager`` and log in to the Cloud Manager.
* Select the group from the dropdown box on the page.
* Go to Settings, Group Settings and add a Preferred Hostnames regexp as
``^mdb-instance-[0-9]{1,2}$``. It may take up to 5 mins till this setting
is in effect. You may refresh the browser window and verify whether the changes
have been saved or not.
* Next, click the ``Deployment`` tab, and then the ``Manage Existing`` button.
* On the ``Import your deployment for monitoring`` page, enter the hostname as
``mdb-instance-0``, port number as ``27017``, with no authentication and no
TLS/SSL settings.
* Once the deployment is found, click the ``Continue`` button.
This may take about a minute or two.
* Do not add ``Automation Agent`` when given an option to add it.
* Verify on the UI that data is being by the monitoring agent.
Step 15. Start a Kubernetes Deployment for MongoDB Backup Agent
---------------------------------------------------------------
* Change both ``metadata.name`` and ``spec.template.metadata.labels.app``
to ``mdb-backup-instance-0-dep``.
.. code:: bash
kubectl --context k8s-bdb-test-cluster-0 apply -f mongodb-backup-agent/mongo-backup-dep.yaml
* Get the pod name and check its logs:
.. code:: bash
kubectl --context k8s-bdb-test-cluster-0 get po
kubectl --context k8s-bdb-test-cluster-0 logs -f <pod name>
Step 16. Configure MongoDB Cloud Manager for Backup
---------------------------------------------------
* Open `MongoDB Cloud Manager <https://cloud.mongodb.com>`_.
* Click ``Login`` under ``MongoDB Cloud Manager`` and log in to the Cloud
Manager.
* Select the group from the dropdown box on the page.
* Click ``Backup`` tab.
* Click on the ``Begin Setup``.
* Click on ``Next``, select the replica set from the dropdown menu.
* Verify the details of your MongoDB instance and click on ``Start`` again.
* It might take up to 5 minutes to start the backup process.
* Verify that data is being backed up on the UI.
Step 17. Verify that the Cluster is Correctly Set Up
----------------------------------------------------
* Start the toolbox container in the cluster
.. code:: bash
kubectl --context k8s-bdb-test-cluster-0 \
run -it toolbox \
--image bigchaindb/toolbox \
--image-pull-policy=Always \
--restart=Never --rm
* Verify MongoDB instance
.. code:: bash
nslookup mdb-instance-0
dig +noall +answer _mdb-port._tcp.mdb-instance-0.default.svc.cluster.local SRV
curl -X GET http://mdb-instance-0:27017
* Verify BigchainDB instance
.. code:: bash
nslookup bdb-instance-0
dig +noall +answer _bdb-port._tcp.bdb-instance-0.default.svc.cluster.local SRV
curl -X GET http://bdb-instance-0:9984
* Verify NGINX instance
.. code:: bash
nslookup ngx-instance-0
dig +noall +answer _ngx-public-mdb-port._tcp.ngx-instance-0.default.svc.cluster.local SRV
curl -X GET http://ngx-instance-0:27017 # results in curl: (56) Recv failure: Connection reset by peer
dig +noall +answer _ngx-public-bdb-port._tcp.ngx-instance-0.default.svc.cluster.local SRV
* If you have run the vanilla NGINX instance, run
.. code:: bash
curl -X GET http://ngx-instance-0:80
* If you have the OpenResty NGINX + 3scale instance, run
.. code:: bash
curl -X GET https://ngx-instance-0
* Check the MongoDB monitoring and backup agent on the MOngoDB Coud Manager portal to verify they are working fine.
* Send some transactions to BigchainDB and verify it's up and running!

This section is about how to set up a BigchainDB cluster where each node is operated by a different operator. If you want to set up and run a testing cluster on AWS (where all nodes are operated by you), then see [the section about that](aws-testing-cluster.html).
## Initial Checklist
## Initial Questions
There are many questions that must be answered before setting up a BigchainDB cluster. For example:
* Do you have a governance process for making consortium-level decisions, such as how to admit new members?
* What will you store in creation transactions (data payload)? Is there a data schema?
@ -15,14 +17,12 @@ This section is about how to set up a BigchainDB cluster where each node is oper
The consortium must decide some things before setting up the initial cluster (initial set of BigchainDB nodes):
1. Who will operate a node in the initial cluster?
2. What will the replication factor be? (It must be 3 or more for [RethinkDB failover](https://rethinkdb.com/docs/failover/) to work.)
3. Which node will be responsible for sending the commands to configure the RethinkDB database?
1. Who will operate each node in the initial cluster?
2. What will the replication factor be? (It should be 3 or more.)
3. Who will deploy the first node, second node, etc.?
Once those things have been decided, each node operator can begin setting up their BigchainDB (production) node.
Once those things have been decided, the cluster deployment process can begin. The process for deploying a production node is outlined in [the section on production nodes](../production-nodes/index.html).
Each node operator will eventually need two pieces of information from all other nodes:
1. Their RethinkDB hostname, e.g. `rdb.farm2.organization.org`
2. Their BigchainDB public key, e.g. `Eky3nkbxDTMgkmiJC8i5hKyVFiAQNmPP4a2G4JdDxJCK`
Every time a new BigchainDB node is added, every other node must update their [BigchainDB keyring](../server-reference/configuration.html#keyring) (one of the BigchainDB configuration settings): they must add the public key of the new node.
To secure communications between BigchainDB nodes, each BigchainDB node can use a firewall or similar, and doing that will require additional coordination.

Later, when we get to the models for the block and the vote, we'll see that both include a signature (from the node which created it). You may wonder why transactions don't have signatures... The answer is that they do! They're just hidden inside the ``fulfillment`` string of each input. A creation transaction is signed by whoever created it. A transfer transaction is signed by whoever currently controls or owns it.
What gets signed? For each input in the transaction, the "fullfillment message" that gets signed includes the ``operation``, ``data``, ``version``, ``id``, corresponding ``condition``, and the fulfillment itself, except with its fulfillment string set to ``null``. The computed signature goes into creating the ``fulfillment`` string of the input.

# Production Node Assumptions
If you're not sure what we mean by a BigchainDB *node*, *cluster*, *consortium*, or *production node*, then see [the section in the Introduction where we defined those terms](../introduction.html#some-basic-vocabulary).
We make some assumptions about production nodes:
1. **Each production node is set up and managed by an experienced professional system administrator (or a team of them).**
2. Each production node in a cluster is managed by a different person or team.
Because of the first assumption, we don't provide a detailed cookbook explaining how to secure a server, or other things that a sysadmin should know. (We do provide some [templates](../cloud-deployment-templates/index.html), but those are just a starting point.)

# Production Node Components
A BigchainDB node must include, at least:
* BigchainDB Server and
* RethinkDB Server.
When doing development and testing, it's common to install both on the same machine, but in a production environment, it may make more sense to install them on separate machines.
In a production environment, a BigchainDB node should have several other components, including:
* nginx or similar, as a reverse proxy and/or load balancer for the Gunicorn server(s) inside the node
* An NTP daemon running on all machines running BigchainDB code, and possibly other machines
* A RethinkDB proxy server
* A RethinkDB "wire protocol firewall" (in the future: this component doesn't exist yet)
* Scalable storage for RethinkDB (e.g. using RAID)
* Monitoring software, to monitor all the machines in the node
* Configuration management agents (if you're using a configuration managment system that uses agents)
* Maybe more
The relationship between these components is illustrated below.

# Set Up and Run a Cluster Node
This is a page of general guidelines for setting up a production node. It says nothing about how to upgrade software, storage, processing, etc. or other details of node management. It will be expanded more in the future.
## Get a Server
The first step is to get a server (or equivalent) which meets [the requirements for a BigchainDB node](node-requirements.html).
## Secure Your Server
The steps that you must take to secure your server depend on your server OS and where your server is physically located. There are many articles and books about how to secure a server. Here we just cover special considerations when securing a BigchainDB node.
There are some [notes on BigchainDB-specific firewall setup](../appendices/firewall-notes.html) in the Appendices.
## Sync Your System Clock
A BigchainDB node uses its system clock to generate timestamps for blocks and votes, so that clock should be kept in sync with some standard clock(s). The standard way to do that is to run an NTP daemon (Network Time Protocol daemon) on the node. (You could also use tlsdate, which uses TLS timestamps rather than NTP, but don't: it's not very accurate and it will break with TLS 1.3, which removes the timestamp.)
NTP is a standard protocol. There are many NTP daemons implementing it. We don't recommend a particular one. On the contrary, we recommend that different nodes in a cluster run different NTP daemons, so that a problem with one daemon won't affect all nodes.
Please see the [notes on NTP daemon setup](../appendices/ntp-notes.html) in the Appendices.
## Set Up Storage for RethinkDB Data
Below are some things to consider when setting up storage for the RethinkDB data. The Appendices have a [section with concrete examples](../appendices/example-rethinkdb-storage-setups.html).
We suggest you set up a separate storage "device" (partition, RAID array, or logical volume) to store the RethinkDB data. Here are some questions to ask:
* How easy will it be to add storage in the future? Will I have to shut down my server?
* How big can the storage get? (Remember that [RAID](https://en.wikipedia.org/wiki/RAID) can be used to make several physical drives look like one.)
* How fast can it read & write data? How many input/output operations per second (IOPS)?
* How does IOPS scale as more physical hard drives are added?
* What's the latency?
* What's the reliability? Is there replication?
* What's in the Service Level Agreement (SLA), if applicable?
* What's the cost?
There are many options and tradeoffs. Don't forget to look into Amazon Elastic Block Store (EBS) and Amazon Elastic File System (EFS), or their equivalents from other providers.
**Storage Notes Specific to RethinkDB**
* The RethinkDB storage engine has a number of SSD optimizations, so you _can_ benefit from using SSDs. ([source](https://www.rethinkdb.com/docs/architecture/))
* If you want a RethinkDB cluster to store an amount of data D, with a replication factor of R (on every table), and the cluster has N nodes, then each node will need to be able to store R×D/N data.
* RethinkDB tables can have [at most 64 shards](https://rethinkdb.com/limitations/). For example, if you have only one table and more than 64 nodes, some nodes won't have the primary of any shard, i.e. they will have replicas only. In other words, once you pass 64 nodes, adding more nodes won't provide more storage space for new data. If the biggest single-node storage available is d, then the most you can store in a RethinkDB cluster is < 64×d: accomplished by putting one primary shard in each of 64 nodes, with all replica shards on other nodes. (This is assuming one table. If there are T tables, then the most you can store is < 64×d×T.)
* When you set up storage for your RethinkDB data, you may have to select a filesystem. (Sometimes, the filesystem is already decided by the choice of storage.) We recommend using a filesystem that supports direct I/O (Input/Output). Many compressed or encrypted file systems don't support direct I/O. The ext4 filesystem supports direct I/O (but be careful: if you enable the data=journal mode, then direct I/O support will be disabled; the default is data=ordered). If your chosen filesystem supports direct I/O and you're using Linux, then you don't need to do anything to request or enable direct I/O. RethinkDB does that.
<p style="background-color: lightgrey;">What is direct I/O? It allows RethinkDB to write directly to the storage device (or use its own in-memory caching mechanisms), rather than relying on the operating system's file read and write caching mechanisms. (If you're using Linux, a write-to-file normally writes to the in-memory Page Cache first; only later does that Page Cache get flushed to disk. The Page Cache is also used when reading files.)</p>
* RethinkDB stores its data in a specific directory. You can tell RethinkDB _which_ directory using the RethinkDB config file, as explained below. In this documentation, we assume the directory is `/data`. If you set up a separate device (partition, RAID array, or logical volume) to store the RethinkDB data, then mount that device on `/data`.
## Install RethinkDB Server
If you don't already have RethinkDB Server installed, you must install it. The RethinkDB documentation has instructions for [how to install RethinkDB Server on a variety of operating systems](https://rethinkdb.com/docs/install/).
## Configure RethinkDB Server
Create a RethinkDB configuration file (text file) named `instance1.conf` with the following contents (explained below):
```text
directory=/data
bind=all
direct-io
# Replace node?_hostname with actual node hostnames below, e.g. rdb.examples.com
join=node0_hostname:29015
join=node1_hostname:29015
join=node2_hostname:29015
# continue until there's a join= line for each node in the cluster
```
* `directory=/data` tells the RethinkDB node to store its share of the database data in `/data`.
* `bind=all` binds RethinkDB to all local network interfaces (e.g. loopback, Ethernet, wireless, whatever is available), so it can communicate with the outside world. (The default is to bind only to local interfaces.)
* `direct-io` tells RethinkDB to use direct I/O (explained earlier). Only include this line if your file system supports direct I/O.
* `join=hostname:29015` lines: A cluster node needs to find out the hostnames of all the other nodes somehow. You _could_ designate one node to be the one that every other node asks, and put that node's hostname in the config file, but that wouldn't be very decentralized. Instead, we include _every_ node in the list of nodes-to-ask.
If you're curious about the RethinkDB config file, there's [a RethinkDB documentation page about it](https://www.rethinkdb.com/docs/config-file/). The [explanations of the RethinkDB command-line options](https://rethinkdb.com/docs/cli-options/) are another useful reference.
See the [RethinkDB documentation on securing your cluster](https://rethinkdb.com/docs/security/).
## Install Python 3.4+
If you don't already have it, then you should [install Python 3.4+](https://www.python.org/downloads/).
If you're testing or developing BigchainDB on a stand-alone node, then you should probably create a Python 3.4+ virtual environment and activate it (e.g. using virtualenv or conda). Later we will install several Python packages and you probably only want those installed in the virtual environment.
## Install BigchainDB Server
First, [install the OS-level dependencies of BigchainDB Server (link)](../appendices/install-os-level-deps.html).
With OS-level dependencies installed, you can install BigchainDB Server with `pip` or from source.
### How to Install BigchainDB with pip
BigchainDB (i.e. both the Server and the officially-supported drivers) is distributed as a Python package on PyPI so you can install it using `pip`. First, make sure you have an up-to-date Python 3.4+ version of `pip` installed:
```text
pip -V
```
If it says that `pip` isn't installed, or it says `pip` is associated with a Python version less than 3.4, then you must install a `pip` version associated with Python 3.4+. In the following instructions, we call it `pip3` but you may be able to use `pip` if that refers to the same thing. See [the `pip` installation instructions](https://pip.pypa.io/en/stable/installing/).
On Ubuntu 16.04, we found that this works:
```text
sudo apt-get install python3-pip
```
That should install a Python 3 version of `pip` named `pip3`. If that didn't work, then another way to get `pip3` is to do `sudo apt-get install python3-setuptools` followed by `sudo easy_install3 pip`.
You can upgrade `pip` (`pip3`) and `setuptools` to the latest versions using:
```text
pip3 install --upgrade pip setuptools
pip3 -V
```
Now you can install BigchainDB Server (and officially-supported BigchainDB drivers) using:
```text
pip3 install bigchaindb
```
(If you're not in a virtualenv and you want to install bigchaindb system-wide, then put `sudo` in front.)
Note: You can use `pip3` to upgrade the `bigchaindb` package to the latest version using `pip3 install --upgrade bigchaindb`.
### How to Install BigchainDB from Source
If you want to install BitchainDB from source because you want to use the very latest bleeding-edge code, clone the public repository:
```text
git clone git@github.com:bigchaindb/bigchaindb.git
python setup.py install
```
## Configure BigchainDB Server
Start by creating a default BigchainDB config file:
```text
bigchaindb -y configure rethinkdb
```
(There's documentation for the `bigchaindb` command is in the section on [the BigchainDB Command Line Interface (CLI)](bigchaindb-cli.html).)
Edit the created config file:
* Open `$HOME/.bigchaindb` (the created config file) in your text editor.
* Change `"server": {"bind": "localhost:9984", ... }` to `"server": {"bind": "0.0.0.0:9984", ... }`. This makes it so traffic can come from any IP address to port 9984 (the HTTP Client-Server API port).
* Change `"keyring": []` to `"keyring": ["public_key_of_other_node_A", "public_key_of_other_node_B", "..."]` i.e. a list of the public keys of all the other nodes in the cluster. The keyring should _not_ include your node's public key.
For more information about the BigchainDB config file, see [Configuring a BigchainDB Node](configuration.html).
## Run RethinkDB Server
Start RethinkDB using:
```text
rethinkdb --config-file path/to/instance1.conf
```
except replace the path with the actual path to `instance1.conf`.
Note: It's possible to [make RethinkDB start at system startup](https://www.rethinkdb.com/docs/start-on-startup/).
You can verify that RethinkDB is running by opening the RethinkDB web interface in your web browser. It should be at `http://rethinkdb-hostname:8080/`. If you're running RethinkDB on localhost, that would be [http://localhost:8080/](http://localhost:8080/).
## Run BigchainDB Server
After all node operators have started RethinkDB, but before they start BigchainDB, one designated node operator must configure the RethinkDB database by running the following commands:
```text
bigchaindb init
bigchaindb set-shards numshards
bigchaindb set-replicas numreplicas
```
where:
* `bigchaindb init` creates the database within RethinkDB, the tables, the indexes, and the genesis block.
* `numshards` should be set to the number of nodes in the initial cluster.
* `numreplicas` should be set to the database replication factor decided by the consortium. It must be 3 or more for [RethinkDB failover](https://rethinkdb.com/docs/failover/) to work.
Once the RethinkDB database is configured, every node operator can start BigchainDB using:
```text
bigchaindb start
```

# Production Node Assumptions
Be sure you know the key BigchainDB terminology:
* [BigchainDB node, BigchainDB cluster and BigchainDB consortum](https://docs.bigchaindb.com/en/latest/terminology.html)
* [dev/test node, bare-bones node and production node](../introduction.html)
We make some assumptions about production nodes:
1. Production nodes use MongoDB, not RethinkDB.
1. Each production node is set up and managed by an experienced professional system administrator or a team of them.
1. Each production node in a cluster is managed by a different person or team.
You can use RethinkDB when building prototypes, but we don't advise or support using it in production.
We don't provide a detailed cookbook explaining how to secure a server, or other things that a sysadmin should know. (We do provide some [templates](../cloud-deployment-templates/index.html), but those are just a starting point.)

# Production Node Components
A production BigchainDB node must include:
* BigchainDB Server
* MongoDB Server 3.4+ (mongod)
* Scalable storage for MongoDB
It could also include several other components, including:
* NGINX or similar, to provide authentication, rate limiting, etc.
* An NTP daemon running on all machines running BigchainDB Server or mongod, and possibly other machines
* **Not** MongoDB Automation Agent. It's for automating the deployment of an entire MongoDB cluster, not just one MongoDB node within a cluster.
* MongoDB Monitoring Agent
* MongoDB Backup Agent
* Log aggregation software
* Monitoring software
* Maybe more
The relationship between the main components is illustrated below. Note that BigchainDB Server must be able to communicate with the _primary_ MongoDB instance, and any of the MongoDB instances might be the primary, so BigchainDB Server must be able to communicate with all the MongoDB instances. Also, all MongoDB instances must be able to communicate with each other.

# Production Node Requirements
**This page is about the requirements of BigchainDB Server.** You can find the requirements of MongoDB, NGINX, your NTP daemon, your monitoring software, and other [production node components](node-components.html) in the documentation for that software.
## OS Requirements
BigchainDB Server requires Python 3.4+ and Python 3.4+ [will run on any modern OS](https://docs.python.org/3.4/using/index.html), but we recommend using an LTS version of [Ubuntu Server](https://www.ubuntu.com/server) or a similarly server-grade Linux distribution.
_Don't use macOS_ (formerly OS X, formerly Mac OS X), because it's not a server-grade operating system. Also, BigchaindB Server uses the Python multiprocessing package and [some functionality in the multiprocessing package doesn't work on Mac OS X](https://docs.python.org/3.4/library/multiprocessing.html#multiprocessing.Queue.qsize).
## General Considerations
BigchainDB Server runs many concurrent processes, so more RAM and more CPU cores is better.
As mentioned on the page about [production node components](node-components.html), every machine running BigchainDB Server should be running an NTP daemon.

# Using a Reverse Proxy
You may want to:
* rate limit inbound HTTP requests,
* authenticate/authorize inbound HTTP requests,
* block requests with an HTTP request body that's too large, or
* enable HTTPS (TLS) between your users and your node.
While we could have built all that into BigchainDB Server,
we didn't, because you can do all that (and more)
using a reverse proxy such as NGINX or HAProxy.
(You would put it in front of your BigchainDB Server,
so that all inbound HTTP requests would arrive
at the reverse proxy before *maybe* being proxied
onwards to your BigchainDB Server.)
For detailed instructions, see the documentation
for your reverse proxy.
Below, we note how a reverse proxy can be used
to do some BigchainDB-specific things.
You may also be interested in
[our NGINX configuration file template](https://github.com/bigchaindb/nginx_3scale/blob/master/nginx.conf.template)
(open source, on GitHub).
## Enforcing a Max Transaction Size
The BigchainDB HTTP API has several endpoints,
but only one of them, the `POST /transactions` endpoint,
expects a non-empty HTTP request body:
the transaction (JSON) being submitted by the user.
If you want to enforce a maximum-allowed transaction size
(discarding any that are larger),
then you can do so by configuring a maximum request body size
in your reverse proxy.
For example, NGINX has the `client_max_body_size`
configuration setting. You could set it to 15 kB
with the following line in your NGINX config file:
```text
client_max_body_size 15k;
```
For more information, see
[the NGINX docs about client_max_body_size](https://nginx.org/en/docs/http/ngx_http_core_module.html#client_max_body_size).
Note: By enforcing a maximum transaction size, you
[indirectly enforce a maximum crypto-conditions complexity](https://github.com/bigchaindb/bigchaindb/issues/356#issuecomment-288085251).
**Aside: Why 15 kB?**
Both [RethinkDB](https://rethinkdb.com/limitations/) and
[MongoDB have a maximum document size of 16 MB](https://docs.mongodb.com/manual/reference/limits/#limit-bson-document-size).
In BigchainDB, the biggest documents are the blocks.
A BigchainDB block can contain up to 1000 transactions,
plus some other data (e.g. the timestamp).
If we ignore the other data as negligible relative to all the transactions,
then a block of size 16 MB
will have an average transaction size of (16 MB)/1000 = 16 kB.
Therefore by limiting the max transaction size to 15 kB,
you can be fairly sure that no blocks will ever be
bigger than 16 MB.
Note: Technically, the documents that MongoDB stores aren't the JSON
that BigchainDB users think of; they're JSON converted to BSON.
Moreover, [one can use GridFS with MongoDB to store larger documents](https://docs.mongodb.com/manual/core/gridfs/).
Therefore the above calculation shoud be seen as a rough guide,
not the last word.

# Set Up and Run a Cluster Node
This is a page of general guidelines for setting up a production BigchainDB node. Before continuing, make sure you've read the pages about production node [assumptions](node-assumptions.html), [components](node-components.html) and [requirements](node-requirements.html).
Note: These are just guidelines. You can modify them to suit your needs. For example, if you want to initialize the MongoDB replica set before installing BigchainDB, you _can_ do that. If you'd prefer to use Docker and Kubernetes, you can (and [we have a template](../cloud-deployment-templates/node-on-kubernetes.html)). We don't cover all possible setup procedures here.
## Security Guidelines
There are many articles, websites and books about securing servers, virtual machines, networks, etc. Consult those.
There are some [notes on BigchainDB-specific firewall setup](../appendices/firewall-notes.html) in the Appendices.
## Sync Your System Clock
A BigchainDB node uses its system clock to generate timestamps for blocks and votes, so that clock should be kept in sync with some standard clock(s). The standard way to do that is to run an NTP daemon (Network Time Protocol daemon) on the node.
MongoDB also recommends having an NTP daemon running on all MongoDB nodes.
NTP is a standard protocol. There are many NTP daemons implementing it. We don't recommend a particular one. On the contrary, we recommend that different nodes in a cluster run different NTP daemons, so that a problem with one daemon won't affect all nodes.
Please see the [notes on NTP daemon setup](../appendices/ntp-notes.html) in the Appendices.
## Set Up Storage for MongoDB
We suggest you set up a separate storage device (partition, RAID array, or logical volume) to store the data in the MongoDB database. Here are some questions to ask:
* How easy will it be to add storage in the future? Will I have to shut down my server?
* How big can the storage get? (Remember that [RAID](https://en.wikipedia.org/wiki/RAID) can be used to make several physical drives look like one.)
* How fast can it read & write data? How many input/output operations per second (IOPS)?
* How does IOPS scale as more physical hard drives are added?
* What's the latency?
* What's the reliability? Is there replication?
* What's in the Service Level Agreement (SLA), if applicable?
* What's the cost?
There are many options and tradeoffs.
Consult the MongoDB documentation for its recommendations regarding storage hardware, software and settings, e.g. in the [MongoDB Production Notes](https://docs.mongodb.com/manual/administration/production-notes/).
## Install and Run MongoDB
* [Install MongoDB 3.4+](https://docs.mongodb.com/manual/installation/). (BigchainDB only works with MongoDB 3.4+.)
* [Run MongoDB (mongod)](https://docs.mongodb.com/manual/reference/program/mongod/)
## Install BigchainDB Server
### Install BigchainDB Server Dependencies
Before you can install BigchainDB Server, you must [install its OS-level dependencies](../appendices/install-os-level-deps.html) and you may have to [install Python 3.4+](https://www.python.org/downloads/).
### How to Install BigchainDB Server with pip
BigchainDB is distributed as a Python package on PyPI so you can install it using `pip`. First, make sure you have an up-to-date Python 3.4+ version of `pip` installed:
```text
pip -V
```
If it says that `pip` isn't installed, or it says `pip` is associated with a Python version less than 3.4, then you must install a `pip` version associated with Python 3.4+. In the following instructions, we call it `pip3` but you may be able to use `pip` if that refers to the same thing. See [the `pip` installation instructions](https://pip.pypa.io/en/stable/installing/).
On Ubuntu 16.04, we found that this works:
```text
sudo apt-get install python3-pip
```
That should install a Python 3 version of `pip` named `pip3`. If that didn't work, then another way to get `pip3` is to do `sudo apt-get install python3-setuptools` followed by `sudo easy_install3 pip`.
You can upgrade `pip` (`pip3`) and `setuptools` to the latest versions using:
```text
pip3 install --upgrade pip setuptools
pip3 -V
```
Now you can install BigchainDB Server using:
```text
pip3 install bigchaindb
```
(If you're not in a virtualenv and you want to install bigchaindb system-wide, then put `sudo` in front.)
Note: You can use `pip3` to upgrade the `bigchaindb` package to the latest version using `pip3 install --upgrade bigchaindb`.
### How to Install BigchainDB Server from Source
If you want to install BitchainDB from source because you want to use the very latest bleeding-edge code, clone the public repository:
```text
git clone git@github.com:bigchaindb/bigchaindb.git
cd bigchaindb
python setup.py install
```
## Configure BigchainDB Server
Start by creating a default BigchainDB config file for a MongoDB backend:
```text
bigchaindb -y configure mongodb
```
(There's documentation for the `bigchaindb` command is in the section on [the BigchainDB Command Line Interface (CLI)](../server-reference/bigchaindb-cli.html).)
Edit the created config file by opening `$HOME/.bigchaindb` (the created config file) in your text editor:
* Change `"server": {"bind": "localhost:9984", ... }` to `"server": {"bind": "0.0.0.0:9984", ... }`. This makes it so traffic can come from any IP address to port 9984 (the HTTP Client-Server API port).
* Change `"keyring": []` to `"keyring": ["public_key_of_other_node_A", "public_key_of_other_node_B", "..."]` i.e. a list of the public keys of all the other nodes in the cluster. The keyring should _not_ include your node's public key.
* Ensure that `database.host` and `database.port` are set to the hostname and port of your MongoDB instance. (The port is usually 27017, unless you changed it.)
For more information about the BigchainDB config file, see the page about the [BigchainDB configuration settings](../server-reference/configuration.html).
## Get All Other Nodes to Update Their Keyring
All other BigchainDB nodes in the cluster must add your new node's public key to their BigchainDB keyring. Currently, the only way to get BigchainDB Server to "notice" a changed keyring is to shut it down and start it back up again (with the new keyring).
## Maybe Update the MongoDB Replica Set
**If this isn't the first node in the BigchainDB cluster**, then someone with an existing BigchainDB node (not you) must add your MongoDB instance to the MongoDB replica set. They can do so (on their node) using:
```text
bigchaindb add-replicas your-mongod-hostname:27017
```
where they must replace `your-mongod-hostname` with the actual hostname of your MongoDB instance, and they may have to replace `27017` with the actual port.
## Start BigchainDB
**Warning: If you're not deploying the first node in the BigchainDB cluster, then don't start BigchainDB before your MongoDB instance has been added to the MongoDB replica set (as outlined above).**
```text
# See warning above
bigchaindb start
```

## database.backend, database.host, database.port, database.name & database.replicaset
## database.*
The database backend to use (`rethinkdb` or `mongodb`) and its hostname, port and name. If the database backend is `mongodb`, then there's a fifth setting: the name of the replica set. If the database backend is `rethinkdb`, you *can* set the name of the replica set, but it won't be used for anything.
The settings with names of the form `database.*` are for the database backend
(currently either RethinkDB or MongoDB). They are:
* `database.backend` is either `rethinkdb` or `mongodb`.
* `database.host` is the hostname (FQDN) of the backend database.
* `database.port` is self-explanatory.
* `database.name` is a user-chosen name for the database inside RethinkDB or MongoDB, e.g. `bigchain`.
* `database.replicaset` is only relevant if using MongoDB; it's the name of the MongoDB replica set, e.g. `bigchain-rs`.
* `database.connection_timeout` is the maximum number of milliseconds that BigchainDB will wait before giving up on one attempt to connect to the database backend. Note: At the time of writing, this setting was only used by MongoDB; there was an open [issue to make RethinkDB use it as well](https://github.com/bigchaindb/bigchaindb/issues/1337).
* `database.max_tries` is the maximum number of times that BigchainDB will try to establish a connection with the database backend. If 0, then it will try forever.

These settings are for the [Gunicorn HTTP server](http://gunicorn.org/), which is used to serve the [HTTP client-server API](../http-client-server-api.html).
`server.bind` is where to bind the Gunicorn HTTP server socket. It's a string. It can be any valid value for [Gunicorn's bind setting](http://docs.gunicorn.org/en/stable/settings.html#bind). If you want to allow IPv4 connections from anyone, on port 9984, use '0.0.0.0:9984'. In a production setting, we recommend you use Gunicorn behind a reverse proxy server. If Gunicorn and the reverse proxy are running on the same machine, then use 'localhost:PORT' where PORT is _not_ 9984 (because the reverse proxy needs to listen on port 9984). Maybe use PORT=9983 in that case because we know 9983 isn't used. If Gunicorn and the reverse proxy are running on different machines, then use 'A.B.C.D:9984' where A.B.C.D is the IP address of the reverse proxy. There's [more information about deploying behind a reverse proxy in the Gunicorn documentation](http://docs.gunicorn.org/en/stable/deploy.html). (They call it a proxy.)
`server.loglevel` sets the log level of Gunicorn's Error log outputs. See
[Gunicorn's documentation](http://docs.gunicorn.org/en/latest/settings.html#loglevel)
for more information.
`server.workers` is [the number of worker processes](http://docs.gunicorn.org/en/stable/settings.html#workers) for handling requests. If `None` (the default), the value will be (cpu_count * 2 + 1). `server.threads` is [the number of threads-per-worker](http://docs.gunicorn.org/en/stable/settings.html#threads) for handling requests. If `None` (the default), the value will be (cpu_count * 2 + 1). The HTTP server will be able to handle `server.workers` * `server.threads` requests simultaneously.

Log files have a size limit of 200 MB and will be rotated up to five times.
For example if we consider the log file setting:
```
{

"file": "~/bigchain.log"
}
}
```
logs would always be written to `bigchain.log`. Each time the file
`bigchain.log` reaches 200 MB it would be closed and renamed
`bigchain.log.1`. If `bigchain.log.1` and `bigchain.log.2` already exist they
would be renamed `bigchain.log.2` and `bigchain.log.3`. This pattern would be
applied up to `bigchain.log.5` after which `bigchain.log.5` would be
overwritten by `bigchain.log.4`, thus ending the rotation cycle of whatever
