  • 1

Throughout this tutorial, you'll learn how to install Redis and the PHP Redis to drastically improve your server's performances

Redis is an open source solution which acts as a database of structured cached data which is stored in a the RAM of your server. Instead of relying on the disk latency, the cache, being in the memory, will provide a way faster throughput. 

The guide presupposed that you have a CentOS 7 server with cPanel installed. If you have a Managed Server the installation can be done by our support.

1) Login through SSH and run the following commands : 

sudo yum install epel-release yum-utils
sudo yum install
sudo yum-config-manager --enable rem
yum install redis

2) Once installed, you would need to start it:

sudo systemctl start redis
sudo systemctl enable redis
sudo systemctl status redis

The latest command should give you a confirmation of that Redis is running.

redis.service - Redis persistent key-value database
Loaded: loaded (/usr/lib/systemd/system/redis.service; enabled; vendor preset: disabled)
Drop-In: /etc/systemd/system/redis.service.d
Active: active (running) since Sat 2020-06-24 15:21:55 GMT +1; 40s ago
Main PID: 2157 (redis-server)
CGroup: /system.slice/redis.service
        └─2157 /usr/bin/redis-server

It also returns the port being used (here 6379) which you may need for your application.
