Get Your Database Up and Running in No Time! 🚀
Welcome, readers! In today’s world, businesses generate and store an enormous amount of data. To deal with that data effectively, installing a robust database system like MariaDB server is crucial. MariaDB server is an open-source database management system that provides all the features of a professional database server, including scalability, security, and reliability. This guide will walk you through the complete process of installing MariaDB server on Debian, one of the most popular Linux distributions. So, let’s get started! 😃
Introduction: Overview of MariaDB and Debian
MariaDB is a community-driven fork of the MySQL relational database management system. It was created by the original developers of MySQL because of concerns over its acquisition by Oracle Corporation. MariaDB offers a high-performance, scalable, and secure database server that is optimized for modern systems. Debian, on the other hand, is a free Linux distribution known for its stability, security, and ease of use. It is widely used in web servers, desktops, and embedded systems. Installing MariaDB server on Debian is a straightforward process that anyone can complete with basic Linux knowledge.

Pre-Installation Checks
Before we start installing MariaDB server on Debian, let’s make sure that we have the necessary prerequisites:
- A running Debian installation with root access
- An active internet connection
Once you have these prerequisites, you can proceed to the next step.
Step-by-Step Guide: Installing MariaDB Server on Debian
Step 1: Update the System
It is always a good practice to update the system before installing any new software. To do this, open a terminal and type:
sudo apt update && sudo apt upgrade
This will update the package lists and upgrade all the installed packages to their latest versions.
Step 2: Install MariaDB Server
To install MariaDB server, run the following command:
sudo apt install mariadb-server
This will install the MariaDB server and all the required dependencies. During the installation, you will be prompted to set a root password for the database server. Make sure to choose a strong and secure password.
Step 3: Secure the MariaDB Installation
After installing MariaDB server, it is recommended to secure the installation by running the following command:
sudo mysql_secure_installation
This command will prompt you to perform several security-related tasks, such as changing the root password, removing anonymous users, disabling remote root login, and removing the test database. Follow the prompts and answer them appropriately.
Step 4: Verify the Installation
To verify that MariaDB server is installed and running, run the following command:
sudo systemctl status mariadb
If the installation is successful, you should see a message that says “Active: active (running)”.
Step 5: Connect to MariaDB Server
To connect to MariaDB server, run the following command:
sudo mysql -u root -p
This will prompt you to enter the root password that you set during the installation. If the password is correct, you should see the MariaDB command prompt.
Step 6: Create a Database and User
Now that you have access to MariaDB server, you can create a new database and user by running the following commands:
CREATE DATABASE mydatabase;
CREATE USER 'myuser'@'localhost' IDENTIFIED BY 'mypassword';
GRANT ALL PRIVILEGES ON mydatabase.* TO 'myuser'@'localhost';
FLUSH PRIVILEGES;
Replace “mydatabase”, “myuser”, and “mypassword” with your desired names and passwords.
Step 7: Test the Database Connection
To test the database connection, create a simple PHP script that connects to the database and displays a message:
<?php
// Database connection parameters
$host = 'localhost';
$user = 'myuser';
$password = 'mypassword';
$database = 'mydatabase';
// Connect to the database
$conn = new mysqli($host, $user, $password, $database);
// Check the connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
// Display a message
echo "Connected successfully!";
?>
Save the script as “test.php” and place it in the document root of your web server. Then, open your web browser and navigate to “http://localhost/test.php”. If everything is configured correctly, you should see the message “Connected successfully!”.
