How To Install RethinkDB on CentOS 8 / CentOS 7

Install RethinkDB on CentOS 8 / CentOS 7

After adding the repository, install RethinkDB on CentOS 8 / CentOS 7 with the command:

sudo yum -y install rethinkdb

Configuring RethinkDB on CentOS 8 / CentOS 7

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

Examples:

Enable http admin console and listen on any address.

### Network options
bind=all

### Web options

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

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.
server-name=server1

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// (where  is the name of this file without the extension)
directory=/var/lib/rethinkdb/default

Set Log directory:

log-file=/var/log/rethinkdb

Set bind address – default is all

bind=all
# bind=all           # Bind to all addresses
# bind=192.168.10.10 # Bind to specific ip address

Create data & log directory /file:

sudo mkdir /var/lib/rethinkdb
sudo touch /var/log/rethinkdb

Set proper permissions

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

Start and enable rethinkdb service service.

sudo systemctl enable rethinkdb
sudo systemctl start rethinkdb

Confirm service status:

$ systemctl status rethinkdb

If you have an active firewall service, allow port 8080:

sudo firewall-cmd --add-port=8080/tcp --permanent
sudo firewall-cmd --reload

Access RethinkDB Web console on the Server IP and port 8080.

You can perform most database operations like add tables, check servers, view logs e.t.c from the web console.

List of servers added to the cluster can be viewed under the Servers section.
