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 would 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 Ubuntu 20.04 LTS.
- Recommended OS: Ubuntu 20.04 – optional (Ubuntu 21.04)
- User account: A user account with sudo or root access.
Updating Operating System
Update your Ubuntu 20.04 operating system to make sure all existing packages are up to date:

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 apt-key adv --fetch-keys 'https://mariadb.org/mariadb_release_signing_key.asc'
Example output if successful:
Executing: /tmp/apt-key-gpghome.HOUXri7uzh/gpg.1.sh --fetch-keys https://mariadb.org/mariadb_release_signing_key.asc
gpg: requesting key from 'https://mariadb.org/mariadb_release_signing_key.asc'
gpg: key F1656F24C74CD1D8: public key "MariaDB Signing Key <[email protected]>" imported
gpg: Total number processed: 1
gpg: imported: 1
Next, run the command in your terminal to import the MariaDB 10.6 repository:
sudo add-apt-repository 'deb [arch=amd64,arm64,ppc64el] https://mariadb.mirror.liquidtelecom.com/repo/10.6/ubuntu focal main'
Note, download mirrors can be found on this page from MariaDB foundation to find a location closer to you for the repository.
Now that the key and repository are imported update the apt package manager list to reflect the new addition.

Secure MariaDB 10.6 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):
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 10.6 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 the root password that you set in either the installation setup or post-installation security script. Once inside the MySQL service instance, you can execute the following command as a test to see it in operation.
Type the following SHOW DATABASE command:
For those new to MySQL, all commands syntax must end with “;”
To exit the terminal, type the following exit command:
Uninstall MariaDB 10.6
If you no longer wish to use MariaDB and want to remove it in full, execute the following command:
sudo apt autoremove mariadb-server mariadb-client
Type Y and then press the enter key to proceed with the uninstallation.
Note that this command will remove most of the unused dependencies included in the MariaDB installation to help clean up your system.
