For Linux (Ubuntu/Debian/Red Hat-based distributions)

The most common way to install MariaDB on Linux is through your system's package manager.

Steps:

1. Update Package List:

   Before installing, it's a good practice to update your package index.

   • For Debian/Ubuntu:Bash

     sudo apt update

   • For Red Hat/CentOS/Fedora:Bash

     sudo yum update # For older systems
     sudo dnf update # For newer systems

2. Install MariaDB Server:

   Install the MariaDB server and client packages.

   • For Debian/Ubuntu:Bash

     sudo apt install mariadb-server mariadb-client galera-4

   • For Red Hat/CentOS/Fedora:Bash

     sudo dnf install mariadb mariadb-server

3. Secure the Installation:

   After installation, run the security script to set a root password, remove anonymous users, and disable remote root login.

   sudo mariadb-secure-installation

   Follow the prompts to configure your security settings.

4. Start and Verify the Service:

   MariaDB typically starts automatically after installation. You can check its status and manually start it if needed.

   • Check status:

     sudo systemctl status mariadb

   • Start service (if not running):Bash

     sudo systemctl start mariadb

   • Verify installation by connecting as root:Bash

     mariadb -u root -p

     Enter the root password you set during the secure installation.

For Windows

For Windows, MariaDB provides an .msi installer for a straightforward graphical installation.

Steps:

1. Download MariaDB:

   Visit the MariaDB downloads page to get the latest .msi installer.

2. Run the Installer:

   Double-click the downloaded .msi file to start the installation wizard.

3. Follow On-Screen Instructions:

   The installer will guide you through the process, including:

   • Accepting the end-user license agreement.

   • Selecting features and the installation directory.

   • Setting a password for the root user.

   • Configuring MariaDB as a service and setting the port (default is 3306).

   • Optionally, enabling UTF8 as the default server character set.

Important Notes:

• Firewall: Ensure your firewall is configured to allow connections to MariaDB on the appropriate port (default 3306) if you need remote access.

• Root Password: Always set a strong root password during the secure installation step.

• Further Configuration: For production environments, you may need to adjust further settings in the MariaDB configuration files (e.g., my.cnf on Linux).
