Preparing for MariaDB Installation

Before installing MariaDB, you need to update your system and set up the correct repository. These steps ensure you get the latest version and avoid potential issues.

Updating System Packages

First, update your Ubuntu package index and upgrade existing packages. Open a terminal and run:

sudo apt update
sudo apt upgrade

This refreshes the list of available packages and installs any updates. It’s a good practice to do this regularly.

Next, install some required packages:

sudo apt install software-properties-common dirmngr apt-transport-https

These tools help manage software repositories and secure connections.

Configuring the MariaDB Repository

To get the latest MariaDB version, add the official MariaDB repository. This ensures you have access to the most up-to-date builds.

First, import the MariaDB GPG key:

sudo apt-key adv --fetch-keys 'https://mariadb.org/mariadb_release_signing_key.asc'

Then, add the MariaDB repository to your system:

sudo add-apt-repository 'deb [arch=amd64,arm64,ppc64el] https://mirror.rackspace.com/mariadb/repo/10.6/ubuntu focal main'

Replace ‘10.6’ with your desired MariaDB version if needed. After adding the repository, update the package index again:

sudo apt update

Your system is now ready for MariaDB installation.

Installing and Securing MariaDB

Installing MariaDB on Ubuntu 22.04 is straightforward. The process involves installing the software, setting up initial security, and managing the service.

Executing the Installation

To install MariaDB on Ubuntu, use the following command:

sudo apt update
sudo apt install mariadb-server

This installs the MariaDB server and related tools. The installation process is quick and doesn’t require user input.

After installation, check the MariaDB version:

mariadb --version

Initial Security Configuration

Run the security script to set up initial security measures:

sudo mysql_secure_installation

This script prompts you to:

Set a root password
Remove anonymous users
Disallow root login remotely
Remove test database
Reload privilege tables

Answer “Y” to all prompts for maximum security. These steps enhance MariaDB’s security by limiting access and removing potential vulnerabilities.

Managing MariaDB Service

Control the MariaDB service using systemctl:

Start MariaDB: sudo systemctl start mariadb
Enable MariaDB to start on boot: sudo systemctl enable mariadb
Check status: sudo systemctl status mariadb
Restart MariaDB: sudo systemctl restart mariadb
Stop MariaDB: sudo systemctl stop mariadb

These commands allow easy management of the MariaDB service. Regular status checks ensure the database is running smoothly.

To further secure MariaDB, consider setting up a firewall and creating separate user accounts with limited privileges for different applications or users.
