Redis is an in-memory data structure store, used as a database server, cache and message broker. It also provides a PHP module for communication between PHP scripts and the Redis server.

This guide will help you with the installation of the Redis server and binding with PHP using Redis PHP extensions on a cPanel server.

Step 1 – Prerequisites

Redis packages are not available under default yum repositories. You need to enable EPEL yum repository on your server first. Execute the following command to enable EPEL:

### CentOS/RHEL 7 
yum install epel-release

Step 2 – Install Redis Server

Next, install Redis using yum

yum install redis

After successfully installing, start Redis service and enable to auto-start on system reboot.

### CentOS/RHEL 7 
systemctl enable redis
systemctl start redis

Redis server is up and is running on your system.

Step 3 – Install Redis PHP extension
