Redis, the open-source in-memory data structure store, has become popular among developers for its exceptional performance and versatility.

What makes Redis useful

Redis offers a wide range of features like caching, real-time analytics, queuing, etc. That makes it an ideal choice for different types of applications. Its in-memory architecture allows it to deliver data at lightning-fast speeds. Its support for various data structures like strings, lists, sets, and hashes, makes it a powerful tool for building complex applications. Redis is also easy to use, deploy, and scale, making it a developer's favorite. In this article, we'll explore Redis and how to set it up on a Linux machine.

How to setup Redis on Linux

NOTE: It's not always applicable but you may need to run an update on your machine to proceed.

Step 1 - Installing Redis using the Terminal

For Arch

sudo pacman -S redis

For Ubuntu

sudo apt install redis

For CentOS

sudo yum install redis

For Fedora

sudo dnf -y install redis

Step 2 - Check the Redis Version

Once the installation is complete, you can check if the installation was successful using this command below:

redis-cli --version

Step 3 - Start the Redis Service

sudo systemctl start redis

Step 4 - Enable the Redis Service

To automatically start Redis on boot run the command below

sudo systemctl enable redis

Step 4 - Verify your installation

sudo systemctl status redis

You should now see something similar to the image below. In the output, locate the Active: active (running) line.

NOTE: If what you saw is Active: inactive, then it means that you must have missed Step 3.

You can also verify your installation using this Ping command.

redis-cli ping

The expected return should be PONG.
