How to Deploy Redis on Rocky Linux 8

Rocky Linux is an ideal distribution for deploying servers and other applications that require robustness. Some of these applications require Redis. That’s why today you will learn how to install Redis on Rocky Linux, and not only that. You will also learn how to configure it and get it ready for your work.

Introduction—What is Redis?

Thanks to AWS, we have the following definition

Redis, which stands for Remote Dictionary Server, is a fast open source in-memory key-value data store. The project started when Salvatore Sanfilippo, the original developer of Redis, was trying to improve the scalability of his Italian start-up company. From there, he developed Redis, which is now used as a database, cache, message broker and queue.

As a result, Redis is emerging as a critical tool in many applications such as chat messaging and for large-scale caching.

Redis offers sub-millisecond response times, enabling millions of requests per second for real-time industry applications such as gaming, advertising technology, financial services, healthcare, and IoT.

Installing Redis on Rocky Linux 8

Fortunately, we can install Redis on Rocky Linux 8, via the distribution’s official repositories. This is a great advantage as you can install it without much effort and with the certainty that it will work.

After you connect to your server with Rocky Linux 8, you have to update it

sudo dnf update

Thereafter, just run

sudo dnf install redis

And it will be quickly installed on your system.

Configure Redis to your liking to get it ready for use.

After it is installed, we need to make some configurations. These are all present in the /etc/redis.conf file, so edit it.

sudo vi /etc/redis.conf

And find the supervised directive and change the value to it. It will look like this.

supervised systemd

This way, Redis will be managed by systemd and the systemctl command.

So, Save your changes and close the editor. Then, start Redis.

sudo systemctl start redis

Then check the status

sudo systemctl status redis
Redis Status
Redis Status

By now, Redis is working correctly and if we type the command

sudo redis-cli ping

We will get PONG as a response and thus verify that Redis is correctly installed.

Another fundamental thing we need to do is to set a password so that not everything is allowed in Redis.

To achieve this, go back to editing the configuration file

sudo vi /etc/redis.conf

And locate the requirepass directive and set an appropriate password for it.

requirepass your-password

Save your changes and close the editor. To apply the changes, restart Redis.

sudo systemctl restart redis

To authenticate, you need to access the Redis console.

sudo redis-cli

And from there, just run

auth your-password

Now you can run whatever you want.

Enabling remote access to Redis

Although not always convenient, some people prefer to enable remote access to Redis. To achieve this, open the Redis configuration file.

sudo vi /etc/redis.conf

Now find the bind directive and assign it the server address

bind [IP]

Another option is to make it reachable from the whole network


After this, find the protected-mode directive and set it to no.

protected-mode no

Save the changes and close the editor.

Finally, restart Redis.

sudo systemctl restart redis

Remember to open port 6379.

sudo firewall-cmd --add-port=6379/tcp --permanent
sudo firewall-cmd --reload

This way you will have Redis up and running.


Thanks to this post, you learned how to install and configure Redis on Rocky Linux 8 to take advantage of this in-memory database concept.

So, I hope you liked it and help us to share it.
