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 10.5 on Ubuntu 20.04 LTS.

Next, run the command in your terminal to import the MariaDB 10.5 repository:
sudo add-apt-repository 'deb [arch=amd64,arm64,ppc64el] https://mariadb.mirror.liquidtelecom.com/repo/10.5/ubuntu focal main'
Now that the key and repository are imported, update the apt package manager list to reflect the new addition.

Secure MariaDB 10.5 with Security Script
When installing MariaDB fresh, default settings 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 10.5 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:
Remove (Uninstall) MariaDB 10.5
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 --purge
Type Y, then press the ENTER KEY to proceed with the removal of MariaDB 10.5. Note, this will also remove all traces from your system.
