How To Install And Configure Redis on Ubuntu

In this article, we have covered how it is easy to install and configure Redis on Ubuntu 22.04. We will install redis-cli 6.0.16.

Redis is an open source (BSD licensed), in-memory data structure store, used as a database, cache and message broker. It supports data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs, geospatial indexes with radius queries and streams.

Redis was designed for use by trusted clients in a trusted environment, and has no robust security features of its own. Redis does, however, have a few security features like a basic unencrypted password as well as command renaming and disabling.

We have covered installation and configuration of Redis.


  • A Ubuntu 22.04 installed dedicated server or KVM VPS.
  • A root user access or normal user with sudo privileges.

Step 1 – Keep the server up to date

apt update && apt upgrade -y

Step 2 – Install Redis

Run following DNF package manager command to install Redis.

apt install redis-server -y

This is important configuration change to make in the Redis configuration file. supervised directive allows you to delivery an init system to manage Redis as a service.

Edit "redis.conf" file.

nano /etc/redis/redis.conf

Find supervised no. Uncomment it and change the supervised value to systemd like shown below:

supervised systemd

Save and exit the Redis configuration file. After editing the file, start and enable the Redis service:

systemctl restart redis
systemctl status redis

To verify that Redis has installed successfully, we can run following command:

redis-cli ping



At this point, Redis is running on our server and we can begin configuring it to enhance its security.

Step 3 – Configure Firewall

If you are using UFW. Add port in the UFW

ufw allow 6379/tcp

Step 4 – Configure a Redit password

Configuring a Redis password enables one of its built-in security features. The auth command, which requires clients to authenticate before being allowed access to the database. Like the bind setting, the password is configured directly in Redis’s configuration file, /etc/redis/redis.conf. Reopen that file:

nano /etc/redis/redis.conf

Find requirepass.

# requirepass foobared

Uncomment it by removing the #, and change foobared to a very strong password of your choosing. You can generate strong password using our Password Generator tool.

After setting the password, save and close the file then restart Redis:

systemctl restart redis

To test that the password works, open the Redis client:


A sequence of commands used to verify whether the Redis password is working is as follows. Before authenticating, the first command tries to set a key to a value:> set key1 23

That won’t work as you have not yet authenticated, so Redis returns an error:

(error) NOAUTH Authentication required.

The following command authenticates with the password specified in the Redis configuration file:> auth your_redis_password

Redis will acknowledge that you have been authenticated:


After that, running the previous command again should be successful:> set key1 23

The get key1 command queries Redis for the value of the new key:> get key1

This last command exits redis-cli. You may also use exit:> quit

Step 5 – Rename Commands

Redis allows us to rename commands as a security feature. Also we can disable certain commands.

To Rename commands, follow this steps:

Edit Redis configuration file.

nano /etc/redis/redis.conf

Add following line:

rename-command FLUSHDB FDB

To disable commands, add follow line:

rename-command FLUSHDB ""

Empty string will disable that command.

Save and exit the configuration file. Then apply the changes by restarting Redis:

systemctl restart redis

You can verify it by running the command in the "redis-cli".

WARNING: avoid using this option if possible. Instead use ACLs to remove commands from the default user, and put them only in some admin user you create for administrative purposes.

Remember: The best time to rename/disable a command is, before your Redis-using application has been deployed
