We assume that you have administrator access to the Ubuntu server, either as root or as a user with sudo privileges.

Install MariaDB on Ubuntu

At the time of this writing, the latest MariaDB version available in the Ubuntu repositories is version 10.3. To install it, run the following commands:

sudo apt updatesudo apt install mariadb-server

Once the installation is complete, the MariaDB service will start automatically. To verify that the database server is running, type the following:

sudo systemctl status mariadb

The output should show that the service is enabled and running:

● mariadb.service - MariaDB 10.3.22 database server
     Loaded: loaded (/lib/systemd/system/mariadb.service; enabled; vendor preset: enabled)
     Active: active (running) since Wed 2020-05-20 16:52:07 UTC; 12s ago
     ...

That’s it. MariaDB has been installed and you can use it.

Log in as root

To interact with the MariaDB server from the command line, use the mysql Client utility or its alias mariadb. This tool is installed as a dependency on the MariaDB server package.

On Ubuntu, the MariaDB root user is from. authenticated auth_socket Plugin by default. The plugin works by checking that the local system user calling the client program matches the specified MariaDB username. This means that you cannot authenticate as root by providing a password.

To log into the MariaDB server as the root user:

sudo mysql

You will be presented with the MariaDB shell as shown below:

Welcome to the MariaDB monitor.  Commands end with ; or g.
Your MariaDB connection id is 61
Server version: 10.3.22-MariaDB-1ubuntu1 Ubuntu 20.04

MariaDB [(none)]> Bye

If you want to log into your MariaDB server as root using an external program like phpMyAdmin, you have two options.

The first is to change the authentication method from auth_socket to mysql_native_password. You can do this by running the following command:

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'very_strong_password';FLUSH PRIVILEGES;

The second recommended option is to create a new dedicated administrator with access to all databases:

GRANT ALL PRIVILEGES ON *.* TO 'administrator'@'localhost' IDENTIFIED BY 'very_strong_password';

You can give the administrator any name you want, but make sure you use a strong password.
