How To Install Redis on Ubuntu 22.04 LTS

Install Redis on Ubuntu 22.04

In this tutorial, we will show you how to install Redis on Ubuntu 22.04 LTS. For those of you who didn’t know, Redis is an open source in-memory data structure store, used as a database, cache, and message broker. Redis supports different kinds of abstract data structures, such as strings, lists, maps, sets, sorted sets, HyperLogLogs, bitmaps, streams, and spatial indices.

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 Ubuntu 22.04 (Jammy Jellyfish). You can follow the same instructions for Ubuntu 22.04 and any other Debian-based distribution like Linux Mint, Elementary OS, Pop!_OS, and more as well.

Prerequisites

  • A server running one of the following operating systems: Ubuntu 22.04, 20.04, and any other Debian-based distribution like Linux Mint.
  • 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 useror 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 Ubuntu 22.04 LTS Jammy Jellyfish

Step 1. First, make sure that all your system packages are up-to-date by running the following apt commands in the terminal.

sudo apt update
sudo apt upgrade
sudo apt install wget apt-transport-https gnupg2 software-properties-common

Step 2. Installing Redis on Ubuntu 22.04.

By default, Redis is available on Ubuntu 22.04 base repository. Now run the following command below to install the latest stable version of Redis to your Ubuntu system:

sudo apt install redis-server

After successfully installation, enable Redis (to start automatically upon system boot), start, and verify the status using the commands below:

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

Confirm the installation and check the installed build version of Redis:

redis-server -v

Step 3. Configure Redis.

The Redis configuration file is located in this path /etc/redis/redis.conf. In this section, we are going to update the Redis configuration file to allow remote access and set an authentication password:

sudo nano /etc/redis/redis.conf

Find line:

requirepass fooboard

Uncomment it by removing the# symbol. After that change “fooboard” with whatever password you want to set for Redis-tool.

Save and close the file, then restart the Redis service to apply changes:

sudo systemctl restart redis

Let’s check whether the Redis tool is asking for a password to send commands or not:

redis-cli

This means we need to supply the password. For that type:

auth your-password

Step 4. Testing Redis.

To test that Redis is functioning correctly, connect to the server using redis-cli, Redis’s command-line client:

redis-cli

Next, type “ping” on the Redis command prompt. On successful connection with the Redis server, you will get PONG as a result:

127.0.0.1:6379> ping
PONG

Congratulations! You have successfully installed Redis. Thanks for using this tutorial for installing Redis on Ubuntu 22.04 LTS Jammy Jellyfish system. For additional help or useful information, we recommend you check the official Redis website.
