How To Install RethinkDB on Oracle Linux 8

RethinkDB is a powerful No-SQL database management system specially designed for applications requiring continuous data access. It supports many popular languages, including PHP, Java, Ruby, and Python. You can use it for automatic failover and robust fault tolerance. RethinkDB has very minimal response times and updates. In addition, it has a beautiful and user-friendly web interface that allows you to manage databases over the web.

This tutorial will show you how to install RethinkDB on Oracle Linux 8.

Step 1 – Install RethinkDB

By default, RethinkDB is not available in the Oracle Linux 8 default repository, so you will need to create a repo for RethinkDB. You can make it with the following command:

nano /etc/yum.repos.d/rethinkdb.repo

Add the following lines:

[rethinkdb]
name=RethinkDB
enabled=1
baseurl=https://download.rethinkdb.com/repository/rocky/8/x86_64/
gpgkey=https://download.rethinkdb.com/repository/raw/pubkey.gpg
gpgcheck=1

dnf install rethinkdb -y

Once the RethinkDB is installed, you can verify the RethinkDB version with the following command:

rethinkdb --version

You should get the following output:

rethinkdb 2.4.2 (GCC 8.5.0)

Step 2 – Configure RethinkDB

First, you will need to copy the RethinkDB sample configuration file with the following command:

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

Next, edit the configuration file using the following command:

nano /etc/rethinkdb/instances.d/instance1.conf

Then, change the following lines to enable the RethinkDB web console:

http-port=8080
server-name=server1

directory=/var/lib/rethinkdb/default
log-file=/var/log/rethinkdb
bind=0.0.0.0  

Save and close the file when you are finished. Next, create the necessary files and provide proper permissions with the following command:

touch /var/log/rethinkdb
chown -R rethinkdb:rethinkdb  /var/log/rethinkdb /var/lib/rethinkdb
chmod -R 775 /var/log/rethinkdb /var/lib/rethinkdb

Now, start the RethinkDB service and enable it to start at system reboot with the following command:

systemctl enable --now rethinkdb
systemctl start rethinkdb

Finally, you can directly verify the status of the RethinkDB service with the following command:

systemctl status rethinkdb

You should get the following output:

● rethinkdb.service - LSB: This starts a set of rethinkdb server instances.
   Loaded: loaded (/etc/rc.d/init.d/rethinkdb; generated)
   Active: active (running) since Fri 2022-09-16 05:06:25 EDT; 4s ago

           └─173907 /usr/bin/rethinkdb --daemon --config-file /etc/rethinkdb/instances.d/instance1.conf --runuser rethinkdb --rungroup rethin>

Sep 16 05:06:24 email.linuxbuz.com rethinkdb[173795]: rethinkdb: instance1: Starting instance. (logging to `/var/log/rethinkdb')

Sep 16 05:06:25 email.linuxbuz.com systemd[1]: Started LSB: This starts a set of rethinkdb server instances..

At this point, RethinkDB is started and listening on port 8080. You can check it with the following command:

ss -antpl | grep 8080

You should get the following output:

LISTEN 0      128                *:8080             *:*    users:(("rethinkdb",pid=173906,fd=25))   

Step 3 – Access RethinkDB Web Interface

Now, open your web browser and access the RethinkDB using the URL http://your-server-ip:8080. You should see the following page:

Now, click on the Tables button. You should see the following page:

Click on the Add Database button. You should see the following page:

Provide your database name and click on the Add button. You should see your database on the next page:
