How To Install Redis on Ubuntu 20.04 LTS

Install Redis on Ubuntu 20.04 LTS

In this tutorial, we will show you how to install Redis on Ubuntu 20.04 LTS. For those of you who didn’t know, Redis is an open-source in-memory key-value data store. It can be used as a database, cache, and message broker, and supports various data structures such as Strings, Hashes, Lists, Sets, and more. Redis provides high availability via Redis Sentinel and automatic partitioning across multiple Redis nodes with Redis Cluster.

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 an Ubuntu 20.04 Focal Fossa.


  • A server running one of the following operating systems: Ubuntu 20.04, 18.04, 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 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.

Install Redis on Ubuntu 20.04 LTS Focal Fossa

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

Step 2. Installing Redis on Ubuntu 20.04.

Redis version 5.0.x is included in the default Ubuntu 20.04 repositories. To install it run the following command:

sudo apt install redis-server

Once the installation is completed, the Redis service will start automatically. To check the status of the service enters the following command:

sudo systemctl status redis-server

You can check the Redis version using the following command:

redis-cli -v

Step 3. Configure Redis Server.

Next, open up the Redis configuration file with your preferred text editor:

sudo nano /etc/redis/redis.conf

Update the following values in the Redis configuration file according to your requirement. You can increase the max memory limit is available on your server:

maxmemory 256mb
maxmemory-policy allkeys-lru

After completing any changes, restart the service once:

sudo systemctl restart redis-server

Step 4. Check Redis Connection.

We will now test the Redis instance with some commands:

$ redis-cli> ping
PONG> set test "Redis Working!"
OK> get test
"Redis Working!"> exit

Congratulations! You have successfully installed Redis. Thanks for using this tutorial for installing Redis in Ubuntu 20.04 LTS Focal Fossa system. For additional help or useful information, we recommend you to check the official Redis website.
