Installing and Configuring MariaDB on AlmaLinux

MariaDB, a robust open-source relational database management system, is a key component for many applications. In this advanced guide, we'll walk you through the installation and configuration of MariaDB on your AlmaLinux system.

Prerequisites:

Ensure you have root or sudo privileges. Before installation, update the package repository:

sudo dnf update -y

Installing MariaDB from Package Manager

Run the MariaDB repository setup script:

wget https://downloads.mariadb.com/MariaDB/mariadb_repo_setup
chmod +x mariadb_repo_setup
sudo ./mariadb_repo_setup

Execute the MariaDB repository setup script to integrate the latest stable release into your system's repositories. This script ensures that your package manager is aware of the up-to-date MariaDB version, allowing you to install it seamlessly.

Use the package manager to install MariaDB:

sudo dnf install mariadb-server -y

This command installs the MariaDB server along with necessary dependencies.

Start and enable MariaDB

sudo systemctl start mariadb
sudo systemctl enable mariadb

Secure MariaDB Server installation

sudo mysql_secure_installation

This script prompts you to set the root password, remove anonymous users, restrict root login to local, and more.

Accessing MariaDB

Log in to MariaDB with the root user:

sudo mariadb -u root -p

Enter the root password when prompted.

Creating a Database and User

Create a new database and user with appropriate privileges:

CREATE DATABASE krython_database;
CREATE USER 'krython_user'@'localhost' IDENTIFIED BY 'krython_password';
GRANT ALL PRIVILEGES ON krython_database.* TO 'krython_user'@'localhost';
FLUSH PRIVILEGES;

Replace krython_database, krython_user, and krython_password with your desired values.

Adjusting MariaDB Configuration

Edit the MariaDB configuration file to optimize performance:

sudo nano /etc/my.cnf.d/server.cnf

Add or modify parameters such as innodb_buffer_pool_size based on your system requirements.

Restarting MariaDB

After making changes, restart the MariaDB service:

sudo systemctl restart mariadb
