Hey folks!. Our blog guide for today is on how to Install RethinkDB on Ubuntu 20.04|18.04|16.04 & Debian 10|9 Linux system. RethinkDB is the leading Open-source, scalable database for building realtime web applications. It enables you to build amazing realtime applications with dramatically less engineering effort.

RethinkDB is a NoSQL database that stores schemaless JSON documents. It was designed with automatic failover and robust fault tolerance in mind. It exposes a new database access model instead of polling for changes, the developer can tell the database to continuously push updated query results to applications in realtime.

Let’s now dive to the installation of RethinkDB on Ubuntu 20.04|18.04|16.04 & Debian 10|9 Linux system.

For CentOS: How To Install RethinkDB on CentOS 8 / CentOS 7

Install RethinkDB on Debian / Ubuntu

There is an official APT repository for both Debian and Ubuntu system where you can install RethinkDB packages from.

Add RethinkDB repository to your system using the commands below.

Add RethinkDB repository to Ubuntu

Add the repository to Ubuntu with the commands:

source /etc/lsb-release && echo "deb https://download.rethinkdb.com/apt $DISTRIB_CODENAME main" | sudo tee /etc/apt/sources.list.d/rethinkdb.list
wget -qO- https://download.rethinkdb.com/apt/pubkey.gpg | sudo apt-key add -

Add RethinkDB repository to Debian

On your Debian machine, add RethinkDB repository with the command:

echo "deb https://download.rethinkdb.com/apt `lsb_release -cs` main" | sudo tee /etc/apt/sources.list.d/rethinkdb.list
wget -qO- https://download.rethinkdb.com/apt/pubkey.gpg | sudo apt-key add -

Install RethinkDB

After adding the repository, update APT cache and install RethinkDB on your Ubuntu / Debian machine.

sudo apt update
sudo apt -y install rethinkdb

Configuring RethinkDB on Ubuntu / Debian

Copy the sample configuration file and use the configuration file documentation as a guide to customize it. (If you don’t have the sample .conf file, you can download it here.)

sudo cp /etc/rethinkdb/default.conf.sample /etc/rethinkdb/instances.d/instance1.conf
sudo vim /etc/rethinkdb/instances.d/instance1.conf


Enable http admin console.

### Web options

## Port for the http admin console
## Default: 8080 + port-offset

Set the name for the server.

### Meta

## The name for this server (as will appear in the metadata).
## If not specified, it will be randomly chosen from a short list of names.

The default Data directory is /var/lib/rethinkdb/ but you can change it.

### File path options

## Directory to store data and metadata
## Command line default: ./rethinkdb_data
## Init script default: /var/lib/rethinkdb/<name>/ (where <name> is the name of this file without the extension)

Restart systemd service.

$ sudo systemctl restart rethinkdb.service 
$ systemctl status rethinkdb.service
