How to Install MySQL 8.4 LTS on Oracle Linux 9

MySQL 8 is a major MySQL series that includes features such as common table expressions, window functions, atomic DDL, and JSON functions.

In this tutorial, we will install MySQL 8 on Oracle Linux 9 from the default repositories.

Oracle Linux 9.6 and later provide the mysql:8.4 AppStream module. This procedure selects that stream explicitly; check the Application Stream lifecycle table.

Prerequisites

Before you install MySQL, you need:

• Oracle Linux 9 fresh installation
• Non-root user with sudo privileges
• Internet connection

Step 1 - Install MySQL 8.4 LTS

Install the MySQL 8.4 server module:

sudo dnf module install mysql:8.4

This selects the MySQL 8.4 stream and its server profile.

Step 2 - Verify the Installed Version

Check the installed MySQL version:

mysql --version

Step 3 - Start MySQL Service

Start the MySQL service:

sudo systemctl start mysqld

Step 4 - Secure the MySQL Installation

Run the mysql_secure_installation script:

sudo mysql_secure_installation

This will set the root password, remove anonymous users etc.

Step 5 - Create MySQL User

Create a dedicated MySQL user for your applications:

-- Run as an administrator before logging in with the application account.
CREATE DATABASE IF NOT EXISTS mytestdb;
-- MySQL 8.0.18+ returns a generated password; save it securely for the connection test.
CREATE USER 'myuser'@'localhost' IDENTIFIED BY RANDOM PASSWORD;
-- CREATE is included for the sample table; use a separate migration account for schema changes in production.
GRANT CREATE, SELECT, INSERT, UPDATE, DELETE ON mytestdb.* TO 'myuser'@'localhost';

Step 6 - Test MySQL

Connect to the MySQL shell:

mysql -u myuser -p
SHOW DATABASES;

Step 7 - Create a Sample Table

Create a table in the sample database:

USE mytestdb;

CREATE TABLE users (
  id INT AUTO_INCREMENT PRIMARY KEY,
  name VARCHAR(50),
  email VARCHAR(50)
);

MySQL is now installed and ready to use!
