How To Install MariaDB on Debian 11

Install MariaDB on Debian 11

In this tutorial, we will show you how to install MariaDB on Debian 11. For those of you who didn’t know, MariaDB is a popular open-source relational database, developed by MySQL developers. Unlike MySQL, MariaDB was meant to be totally free for use. The original creators of MySQL developed MariaDB in response to fears that MySQL will suddenly become a paid service due to Oracle acquiring. With its history of doing similar tactics, the developers behind MariaDB have promised to keep it open source and free from such fears as what has happened to MySQL.

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 through the step-by-step installation of the MariaDB database on a Debian 11 (Bullseye).

Install MariaDB on Debian 11 Bullseye

Step 1. Before we install any software, it’s important to make sure your system is up to date by running the following apt commands in the terminal:

sudo apt update
sudo apt upgrade
sudo apt install software-properties-common dirmngr

Step 2. Installing MariaDB on Debian 11.

Now we add MariaDB signing key and APT repository:

wget https://mariadb.org/mariadb_release_signing_key.asc
sudo chmod -c 644 mariadb_release_signing_key.asc
sudo mv -vi mariadb_release_signing_key.asc /etc/apt/trusted.gpg.d/

Next, add the MariaDB repository manually on your Debian system:

echo "deb [arch=amd64,arm64,ppc64el] \
https://ftp.ubuntu-tw.org/mirror/mariadb/repo/10.6/debian \
bullseye main" | sudo tee /etc/apt/sources.list.d/mariadb.list

Once done, install MariaDB using the following command below:

sudo apt update
sudo apt install mariadb-server

Confirm the installation of MariaDB by checking the version and build:

mariadb --version

Now run the following commands to start MariaDB and enable it to automatically start on system reboot:

sudo systemctl start mariadb
sudo systemctl enable mariadb

Step 3. Secure MariaDB installation.

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

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

You can now connect to the MariaDB server using the new password:

mysql -u root -p
