What Is MariaDB?

MariaDB is a popular, free, and open-source database released as a replacement for MySQL. It is a fork of MySQL, which means MariaDB is an improved version of MySQL with similar but better functionality. Here’s a guide to set up MySQL on Ubuntu if you’d like to try it out.

MariaDB is a fast, scalable, top-notch performing database, with support for more storage engines. It also maintains many plugins, tools, and utilities that make it one of the best databases out there. MariaDB is mostly used to maintain inventories, and manage transactions and customer information.

How to Install MariaDB on Ubuntu 22.04

Here’s how you can install MariaDB on Ubuntu 22.04:

Step 1: Update Your System

To begin with the installation, you first need to update packages on your Ubuntu system. You can achieve this by running the following command on Ubuntu’s terminal:

sudo apt update && sudo apt upgrade

This may take some time, so hang on!

Step 2: Install the Necessary Packages for MariaDB

Once you have updated the system, you need to install some necessary packages required by MariaDB. Do this by executing the following command:

sudo apt-get install wget software-properties-common dirmngr ca-certificates apt-transport-https -y

Now that you’ve installed the essential packages, you will finally install MariaDB in this step. To install the database, run the following command as a root user or with sudo:

sudo apt install mariadb-server mariadb-client

To verify that MariaDB has been successfully installed on your system, check the version of the installed database by issuing the following command:


If you see the version number of the application in the output, this means that MariaDB exists on your system. This is one way to verify the installation. You can also check the active status of the installed database for verification.

Use the following command to check the status of MariaDB:

systemctl status mariadb

As you can see, MariaDB is up and running.

Step 3: Secure Your MariaDB Database

Once you’ve installed and verified the database, the next step is to perform some essential configurations in MariaDB. After installation, it is a good practice to run a security script to protect the MariaDB database from being compromised or attacked. Execute the script with this command:

sudo mysql_secure_installation

Next, the script will ask if you want to set a root password. Provide a secure password and hit Enter. Then, it’ll ask you to reconfirm the password. Once the password is saved, you will get a “Success” message as shown below.

After that, it will ask if you want to remove the anonymous user or not. It is recommended that you remove it.

It will also confirm if you want to disallow remote root login. If you disallow it, you can only log in as a root user from localhost.

By default, MariaDB installs a test database. The script will ask if you want to remove the database or keep it. It is better to delete it and create a new database. However, if you want to keep it for testing purposes, select no.

In the end, the script will take permission from you to reload privilege tables to update the new changes. To load them, enter Y. After you have made the changes, you will see a success message on the terminal.

How to Check if MariaDB Is Running

MariaDB begins to run as soon as it is installed. To test it, you can check the status of MariaDB with the following command:

sudo systemctl status mariadb

If MariaDB is running fine, you will see the following output on Ubuntu’s terminal:

In case, MariaDB is down, you will see a similar output as shown below:

How to Interact With MariaDB on Linux

Now that the installation and configurations are done, let’s explore how you can interact with the database.

1. Access the MariaDB Shell

To enter MariaDB’s shell, run the following command:

sudo mariadb

With this command, the MariaDB monitor will open. Here you can run MariaDB queries to interact with the database.

2. Create a MariaDB Admin Account

After getting access to MariaDB, the first thing you need to do is create a new account with the name “admin”. This account will have the same permissions as the root account, but you will mainly use it for password-based authentication.

To create the admin account with root privileges, use the command below. Make sure to use your password when issuing the command.

GRANT ALL ON *.* TO 'admin'@'localhost' IDENTIFIED BY 'password' WITH GRANT OPTION;

Next, flush the privileges to update the new changes in MariaDB.


You can now exit the MariaDB command line by typing:


3. Create a Database in MariaDB

To create a new database, make use of the following command and provide a name for your database in place of “TestDB”.


To check if the database has been successfully created, use this command to see all the existing databases in MariaDB:

Show Databases;

As you can see TestDB now exists in the list of MariaDB databases.
