MariaDB is an open-source database management system, commonly used as an alternative for the MySQL portion of the popular LAMP (Linux, Apache, MySQL, PHP/Python/Perl) stack. It is intended to be a drop-in replacement for MySQL.
In this tutorial, we will explain how to install the latest version of MariaDB on a Rocky Linux 8 server. If you’re wondering about MySQL vs. MariaDB, MariaDB is the preferred package and should work seamlessly in place of MySQL. If you specifically need MySQL, see the How to Install MySQL on Rocky Linux 8 guide.
To follow this tutorial, you will need a Rocky Linux 8 server with a non-root
sudo-enabled user. You can learn more about how to set up a user with these privileges in the Initial Server Setup with Rocky Linux 8 guide.
You can also use an interactive terminal that is embedded on this page to experiment with installing and configuring MySQL in this tutorial. Click the following
Launch an Interactive Terminal! button to get started.
First, use dnf to install the MariaDB package:
- sudo dnf install mariadb-server
You will be asked to confirm the action. Press
ENTER to proceed.
Once the installation is complete, start the service with
- sudo systemctl start mariadb
Then check the status of the service:
- sudo systemctl status mariadb
Output● mariadb.service - MariaDB 10.3 database server Loaded: loaded (/usr/lib/systemd/system/mariadb.service; disabled; vendor preset: disabled) Active: active (running) since Fri 2020-04-03 17:32:46 UTC; 52min ago Docs: man:mysqld(8) https://mariadb.com/kb/en/library/systemd/ Main PID: 4567 (mysqld) Status: "Taking your SQL requests now..."

Apr 03 17:32:46 rocky8-mariadb systemd: Started MariaDB 10.3 database server.
If MariaDB has successfully started, the output should show
active (running) and the final line should look something like:
OutputApr 03 17:32:46 rocky8-mariadb systemd: Started MariaDB 10.3 database server..
Next, let’s take a moment to ensure that MariaDB starts at boot, using the
systemctl enable command:
- sudo systemctl enable mariadb
OutputCreated symlink /etc/systemd/system/mysql.service → /usr/lib/systemd/system/mariadb.service. Created symlink /etc/systemd/system/mysqld.service → /usr/lib/systemd/system/mariadb.service. Created symlink /etc/systemd/system/multi-user.target.wants/mariadb.service → /usr/lib/systemd/system/mariadb.service.
We now have MariaDB running and configured to run at startup. Next, we’ll turn our attention to securing our installation.
MariaDB includes a security script to change some of the less secure default options for things like remote root logins and sample users. Use this command to run the security script:
- sudo mysql_secure_installation
The script provides a detailed explanation for every step. The first step asks for the root password, which hasn’t been set so we’ll press
ENTER as it recommends. Next, we’ll be prompted to set that root password. Keep in mind that this is for the root database user, not the root user for your Rocky server itself.
ENTER to enter a password for the root database user, then follow the prompts.
After updating the password, we will accept all the security suggestions that follow by pressing
y and then
ENTER. This will remove anonymous users, disallow remote root login, remove the test database, and reload the privilege tables.
Now that we’ve secured the installation, we’ll verify it’s working by connecting to the database.
We can verify our installation and get information about it by connecting with the
mysqladmin tool, a client that lets you run administrative commands. Use the following command to connect to MariaDB as root (
-u root), prompt for a password (
-p), and return the version.
- mysqladmin -u root -p version
You should see output similar to this:
Outputmysqladmin Ver 9.1 Distrib 10.3.17-MariaDB, for Linux on x86_64 Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others. Server version 10.3.17-MariaDB Protocol version 10 Connection Localhost via UNIX socket UNIX socket /var/lib/mysql/mysql.sock Uptime: 6 min 5 sec Threads: 7 Questions: 16 Slow queries: 0 Opens: 17 Flush tables: 1 Open tables: 11 Queries per second avg: 0.043
This indicates the installation has been successful.
In this guide you installed MariaDB to act as an SQL server. During the installation process you also secured the server. Optionally, you also created a separate password-authenticated administrative user.
Now that you have a running and secure MariaDB server, here some examples of next steps that you can take to work with the server:
