How To Install MySQL on Rocky Linux 9

In this tutorial, we will show you how to install MySQL on Rocky Linux 9. For those of you who didn’t know, MySQL is an open-source, cross-platform, and one of the most widely used Relational Database Management Systems (RDMS) distributed by the Oracle Corporation. MySQL has been in production use for over 20 years and is considered one of the most secure and reliable database systems.

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 MySQL 8 on Rocky Linux. 9.

Prerequisites

• A server running one of the following operating systems: Rocky Linux 9.
• It’s recommended that you use a fresh OS install to prevent any potential issues.
• SSH access to the server (or just open Terminal if you’re on a desktop).
• 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 MySQL on Rocky Linux 9

Step 1. The first step is to update your system to the latest version of the package list. To do so, run the following commands:

sudo dnf check-update
sudo dnf install dnf-utils

Step 2. Installing MySQL Database on Rocky Linux 9.

By default, MySQL is available on Rocky Linux 9 base repository. Now run the following command below to install the latest version of MySQL to your system:

sudo dnf install mysql mysql-server mysql-devel

Next, start the MySQL service and enable it to automatically start on boot by running the following command below:

sudo systemctl enable --now mysqld
sudo systemctl start mysqld
sudo systemctl status mysqld

Verify the build of the version of MySQL:

mysql --version

Step 3. Securing MySQL.

By default, MySQL is not hardened. You can secure MySQL 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 MySQL:

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

Step 4. Accessing the MySQL.

Once secured, you can test the connection to your MySQL server:

mysql -u root -p

• mysql is the name of the command you are using to connect to the MySQL server.
• -u root tells MariaDB that you want to log in as the root user.
• -p ensures that you are prompted to enter your password before the MySQL shell will connect.

You will see your MySQL console:

Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 15
Server version: 8.0.31 MySQL Community Server - GPL
