How To Install Redis on Fedora 38

In this tutorial, we will show you how to install Redis on Fedora 38. For those of you who didn’t know, Redis is more than just a database; it’s an efficient and versatile in-memory data structure store. Whether you’re managing cache, sessions, analytics, or real-time data, Redis excels with its support for various data structures such as strings, lists, sets, hashes, and more. Its lightning-fast response times stem from its data-in-memory architecture, making it a top choice for modern applications where speed and responsiveness are paramount.

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 Fedora 38.

Prerequisites

• A server running one of the following operating systems: Fedora 38.
• 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).
• An active internet connection. You’ll need an internet connection to download the necessary packages and dependencies for Redis.
• A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install Redis on Fedora 38

Step 1. Before we can install Redis on Fedora 38, it’s important to ensure that our system is up-to-date with the latest packages. This will ensure that we have access to the latest features and bug fixes and that we can install Redis without any issues:

sudo dnf update

Step 2. Installing Redis on Fedora 38.

Install Redis using the package manager, making the entire process seamless:

sudo dnf install redis

Confirm that Redis has been successfully installed and note the version:

redis-server --version

Step 3. Configuring Redis for Optimal Performance.

• Locating the Configuration File:

Redis’s configuration file is located at /etc/redis.conf. Navigate to this file to access and modify its settings.

nano /etc/redis.conf

• Memory Limits:

Enhance performance by adjusting the maximum memory Redis can utilize. Open the configuration file and find the maxmemory setting. Modify it to suit your application’s requirements.

• Persistence Options:

Ensure your data remains intact across system reboots. In the configuration file, you’ll find save directives. Tweak these to define when Redis should perform automatic data snapshots.

• Enabling Authentication:

Security is paramount. In the configuration file, set a strong password to safeguard your Redis instance:

requirepass Your-Strong-Password

• Cache Eviction Policies:

Redis employs cache eviction policies to manage memory usage. Experiment with different policies to find what suits your application best.

Step 4. Working with Redis Instances.

Control the Redis service using the following commands:

sudo systemctl start redis
sudo systemctl stop redis

Interact with Redis through the command-line interface:

redis-cli

Step 5. Basic Redis Commands with Examples.

• SET and GET Operations:

Store and retrieve data with key-value pairs:

SET username "meilana_maria"
GET username

• Lists and Sets:

Leverage Redis lists and sets for data organization:

LPUSH mylist "item1"
SADD myset "item2"

• Pub/Sub Messaging:

Broadcast messages with Redis’s Pub/Sub feature:

SUBSCRIBE news_channel
PUBLISH news_channel "Breaking News: Redis Rocks!"

• Key Expiration:

Set keys to expire automatically after a certain period:

SETEX session_token 3600 "user12345"
TTL session_token
