How To Install MariaDB on CentOS 9 Stream

In this tutorial, we will show you how to install MariaDB on CentOS 9 Stream. For those of you who didn’t know, MariaDB is a free and open-source database management system and acts as a drop replacement for the Oracle MySQL server. MariaDB is a development of MySQL which puts focus on stability and performance and makes it free to users.

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 the MariaDB on CentOS 9 Stream.

Prerequisites

• A server running one of the following operating systems: CentOS 9 Stream.
• It’s recommended that you use a fresh OS install to prevent any potential issues
• A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install MariaDB on CentOS 9 Stream

Step 1. First, let’s start by ensuring your system is up-to-date.

sudo dnf update

Step 2. Installing the MariaDB on CentOS 9 Stream.

By default, MariaDB is available on the CentOS 9 Stream base repository. Now we run the following command to install MariaDB to your system:

sudo dnf install mariadb-server

Check the version once the installation is complete:

mariadb --version

Once the installation is complete, now enable MariaDB (to start automatically upon system boot), start the MariaDB, and verify the status using the commands below:

sudo systemctl start mariadb
sudo systemctl enable mariadb
sudo systemctl status mariadb

Step 3. Secure MariaDB Installation.

By default, MariaDB is not hardened. You can secure MariaDB using the mysql_secure_installation script. you should read and below each step carefully which will set a root password, remove anonymous users, disallow remote root login, and remove the test database and access to secure MariaDB:

mysql_secure_installation

Configure it like this:

- Set root password? [Y/n] y
- Remove anonymous users? [Y/n] y
- Disallow root login remotely? [Y/n] y
- Remove test database and access to it? [Y/n] y
- Reload privilege tables now? [Y/n] y

To log into MariaDB, use the following command (note that it’s the same command you would use to log into a MariaDB database):

mysql -u root -p

Step 4. Create Database on the MariaDB server.

Now we create database, create MariaDB user and enable remote connections to MariaDB database:

For example uses following parameters:

• DB_NAME = idroot_db
• USER_NAME = idroot_user
• REMOTE_IP = 10.0.46.36
• PASSWORD = your-strong-passwd
• PERMISSIONS = ALL

## CREATE DATABASE ##
MariaDB [(none)]> CREATE DATABASE idroot_db;

## CREATE USER ##
MariaDB [(none)]> CREATE USER 'idroot_user'@'10.0.15.25' IDENTIFIED BY 'your-strong-passwd';

## GRANT PERMISSIONS ##
MariaDB [(none)]> GRANT ALL ON idroot_db.* TO 'idroot_user'@'10.0.46.36';

##  FLUSH PRIVILEGES, Tell the server to reload the grant tables  ##
MariaDB [(none)]> FLUSH PRIVILEGES;

Congratulations! You have successfully installed MariaDB. Thanks for using this tutorial to install the MariaDB on CentOS 9 Stream. For additional help or useful information, we recommend you check the official MariaDB website.
