How to Install MariaDB 10.6 on Debian 11

MariaDB is one of the most popular open-source databases next to its originator MySQL. The original creators of MySQL developed MariaDB in response to fears that MySQL will suddenly become a paid service due to Oracle acquiring it in 2010. 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.

MariaDB has become just as popular as MySQL with developers, with features such as advanced clustering with Galera Cluster 4, faster cache/indexes, storage engines, and features/extensions that you won’t find in MySQL.

In the following tutorial, you will learn how to install MariaDB 10.6 on Debian 11.

Prerequisites

Updating Operating System

Update your Debian 11 operating system to make sure all existing packages are up to date:

sudo apt update && sudo apt upgrade

Install Depedencies

The first step is to install the dependencies needed for the installation. To do this, use the following command in your terminal:

sudo apt-get install curl software-properties-common dirmngr -y

Import GPG Key & Repository

To successfully install MariaDB, you will need to import the GPG key to verify that the packages are from the authentic source and not modified. To do this, use the following command:

sudo curl -LsSO 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/
sudo add-apt-repository 'deb [arch=amd64,arm64,ppc64el] https://mirror.realcompute.io/mariadb/repo/10.6/debian bullseye main'

Note, download mirrors can be found on this page from MariaDB foundation to find a location closer to you for the repository.

Secure MariaDB with Security Script

When installing MariaDB fresh, the default settings that default are considered weak by most standards and cause concern for potentially allowing intrusion or exploiting hackers, a solution is to run the installation security script that comes with the MariaDB installation.

First, use the following command to launch the (mysql_secure_installation):

sudo mysql_secure_installation

Next, follow below:

  • Setting the password for root accounts.
  • Removing root accounts that are accessible from outside the local host.
  • Removing anonymous-user accounts.
  • Removing the test database, which by default can be accessed by anonymous users.

Note, you use (Y) to remove everything.

Login to MariaDB instance

Now that you have completed the post-installation installation security script, login into your MariaDB database can be done using the following:

sudo mysql -u root -p

You will be prompted to enter your root password, and then you will be successfully logged into the MariaDB database terminal:

Example:
