Redis

Redis is a free and open source in memory data structure store. It is widely used as a database, in memory cache or a message broker.

Quick start

To install Redis on Fedora, run the following commands:

$ sudo dnf install redis     # Install redis cli and server
$ sudo systemctl start redis # Initialize redis server

To start redis on boot, run

$ sudo systemctl enable redis

To test redis-cli, run

$ redis-cli ping
pong

Configuring Redis

The config file for Redis is located at /etc/redis/redis.conf.

$ sudo nano /etc/redis/redis.conf

Redis should be always restarted after changing settings. Restart redis by running

$ sudo systemctl restart redis

Secure redis by enabling authentication. Add this line in /etc/redis/redis.conf

requirepass  <AuthPassword>

and after the Redis server restarts, all clients must execute AUTH <AuthPassword> to be able to execute commands in Redis.
