MariaDB is an open-source relational database management system, commonly used as an alternative for MySQL as the database portion of the popular LAMP (Linux, Apache, MySQL, PHP/Python/Perl) stack.

It is intended to be a drop-in replacement for MySQL.

In our previous posts, we have explained how to install MariaDB in Debian , Mint , and CentOS .

Here at LinuxAPT, as part of our Server Management Services, we regularly help our Customers to perform database management related queries.

In this context, we shall look into how to install MariaDB on Ubuntu 20.04.

How to Secure MariaDB after Installation ?

After successfully installing MariaDB, you can secure MariaDB server. We will do this by running a script mysql_secure_installation available on the Linux system. 

This script allows you to configure passwords for root, disable root login remotely, remove root anonymous user accounts and test database, and so on.

To configure the security settings for MariaDB, run the script as follows:

$ sudo mysql_secure_installation

After running the above script, you will be prompted for the various questions. 

It will ask you to provide your root password for MariaDB. As we have not configured it yet, therefore press Enter

Then it will ask if you want to configure a root password, hit y, and then enter the password and confirm by re-entering it.

Then for all the subsequent questions, hit y .


How to Verify MariaDB Service ?

MariaDB service starts running automatically after the installation is completed. 

To verify if the MariaDB service is running fine without any issues, run the following command in Terminal:

$ sudo systemctl status mariadb

It is expected that MariaDB server is active and running.

If the MariaDB service does not run automatically, you can start it manually as follows:

$ sudo systemctl start mariadb


How to connect to MariaDB ?

Now try connecting to the MariaDB server as a root user. 

Run the following command to do so:

$ sudo mysql -u root -p

You will be prompted to enter the root for MariaDB password (that you have configured earlier). 

Once you entered the password, you will be connected to the MariaDB database.


How to uninstall MariaDB from Ubuntu ?

In case, you want to completely remove MariaDB from your system, you can do so easily using the following command in Terminal:

$ sudo apt-get purge mariadb-server

After running the purge command, the system will ask if you want to continue the process by providing you with the y/n option. 

Hit y to carry on the uninstallation process.


Then remove the packages that were automatically installed to satisfy dependencies for MariaDB. 

Run the following command to do so:

$ sudo apt autoremove
