How To Install Redis on CentOS 8

Install Redis on CentOS 8

In this tutorial, we will show you how to install Redis on CentOS 8. For those of you who didn’t know, Redis is an open-source, BSD licensed, advanced key-value store. It is often referred to as a data structure server since keys can contain strings, hashes, lists, sets, and sorted sets. Redis also supports data types such as Transitions, Publish and Subscribe. ‘Redis ’ is considered more powerful than ‘Memcache’. It would be smart to bring ‘Redis’ into practice and put ‘Memcache’ down for a while.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of Redis on a CentOS 8 server.


  • A server running one of the following operating systems: CentOS 8.
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • SSH access to the server (or just open Terminal if you’re on a desktop).
  • A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, you can harm your system if you’re not careful when acting as the root.

Now open it for editing using your favorite text editing:

nano /etc/redis.conf

Then change line 69 bind to below:


After changes in the Redis configuration file, restart the Redis service to apply the changes:

sudo systemctl restart redis

Step 4. Configure Firewall for Redis.

If you have an active firewalld service, allow port 6379:

firewall-cmd --reload

Finally, access the Redis server using the redis-cli client program:

>client list
