How To Install Redis on Linux Mint 20

Install Redis on Linux Mint 20

In this tutorial, we will show you how to install Redis on Linux Mint 20. 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 a Linux Mint 20 (Ulyana).


  • A server running one of the following operating systems: Linux Mint 20 (Ulyana).
  • 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 Linux Mint 20 Ulyana

Step 1. Before running the tutorial below, it’s important to make sure your system is up to date by running the following apt commands in the terminal:

sudo apt update

Step 2. Enable and Install Snapd on the Linux Mint system.

Snap is available for Linux Mint 20, Before install on Linux Mint /etc/apt/preferences.d/nosnap.pref needs to be removed. This can be accomplished from the command line:

sudo rm /etc/apt/preferences.d/nosnap.pref
sudo apt update

Then, run the following command to install Snap:

sudo apt install snapd

Step 3. Installing Redis on Linux Mint 20.

To install Redis, simply use the following command:

sudo snap install redis

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

sudo systemctl status redis-server.service

Step 3. Configure Redis.

Redis can be started without a configuration file using a built-in default configuration. Now, 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 max memory limit as available on your server:

maxmemory 512mb
maxmemory-policy allkeys-lru

The above configuration tells Redis to remove any key using the LRU algorithm when the max memory of 512mb is reached. After completing any changes, restart the service once:

sudo systemctl restart redis-server.service

Step 4. Test Connection to Redis Server.

We will now test the Redis instance with some commands:

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

Few more examples of redis-cli the command-line tools. You can find more details redis-cli here.

Congratulations! You have successfully installed Redis. Thanks for using this tutorial for installing the latest version of Redis on the Linux Mint system. For additional help or useful information, we recommend you to check the official Redis website.
