Redis is a fast, in-memory data structure store that can be used as a database, cache, and message broker. In this tutorial, we will show you how to install Redis on AlmaLinux 8 and switch it from supervised no to supervised systemd.
Step 1: Update your system
Before installing Redis, it's recommended that you update your system's packages to their latest versions. You can do this by running the following command:
dnf update -y
Step 2: Install Redis
To install Redis on AlmaLinux 8, you can use the DNF package manager. Use the following command to install Redis:
dnf install redis -y
Step 3: Configure Redis
By default, Redis is configured to run as a daemon process with supervised no. To switch Redis to supervised systemd, you need to modify the Redis configuration file. You can open the configuration file with a text editor using the following command:
nano /etc/redis.conf
Find the line that starts with supervised no and change it to supervised systemd, like this:
supervised systemd
Save the changes to the configuration file and exit the text editor.
Step 4: Start Redis
After configuring Redis, you can start the Redis service using the following command:
systemctl start redis
To check the status of the Redis service, you can run the following command:
systemctl status redis
If the service is running, the output should show an active (running) status.
Step 5: Enable Redis to start automatically
If you want Redis to start automatically at system boot, you can enable the Redis service using the following command:
systemctl enable redis
This will ensure that Redis starts automatically whenever your system boots up.
