Step 3: Secure the MariaDB Installation
After successfully installing MariaDB on your Debian 12 system, it is crucial to take steps to secure your installation. By implementing appropriate security measures, you can protect your database from unauthorized access and potential security threats.
To secure your MariaDB installation on Debian 12, you can use the default security script provided by MariaDB. This script offers a convenient way to enhance the security of your database. To execute the security script, open the terminal and run the following command:
sudo mariadb-secure-installation
This script will guide you through a series of prompts to configure various security settings. You will be prompted to set a root password, remove anonymous users, restrict root remote access, and remove the test database. It is recommended to follow the prompts and make the necessary selections to secure your MariaDB installation.
Additional Security Measures
In addition to running the security script, there are additional security measures you can consider implementing to further protect your MariaDB installation:
- Regularly update MariaDB and other dependencies to ensure the latest security patches are applied.
- Create separate user accounts with appropriate privileges for different applications and users accessing the database.
- Enable a firewall to restrict access to the MariaDB port (usually port 3306) from unauthorized sources.
- Implement strong password policies for user accounts, including the use of complex passwords and regular password rotations.
- Monitor and review MariaDB logs for any suspicious activity or potential security breaches.
By following these security measures, you can significantly enhance the security of your MariaDB installation on Debian 12 and ensure the integrity of your database.
Step 4: Verify MariaDB Installation
After successfully installing MariaDB on your Debian 12 system, it is important to verify the installation to ensure everything is working correctly. Below are the steps to verify the installation and check the version and service status of MariaDB.

sudo mysql -V
This command will display the version of MariaDB along with additional details such as the distribution name and version.
Check MariaDB Service Status
To verify the status of the MariaDB service, you can use the following command:
sudo systemctl status mariadb
This command will show you whether the MariaDB service is running, along with information about its uptime, active connections, and more.
Verifying the MariaDB installation and service status is crucial to ensure that everything is set up correctly. It allows you to confirm that the installation was successful and that the service is running as expected.
Step 5: Accessing MariaDB
With the installation and security setup complete, you can now access MariaDB. To access the MariaDB shell, open the terminal and enter the following command:
sudo mariadb
This will launch the MariaDB command-line interface, where you can interact with the database and execute SQL queries. The MariaDB shell provides a powerful toolset for managing your database and running various operations.
Using the MariaDB Shell
Once you are inside the MariaDB shell, you can perform a wide range of tasks, such as creating and managing databases, creating tables, inserting data, and running complex queries. Here are a few examples of common commands:
SHOW DATABASES;: Displays a list of all databases in the MariaDB server.USE database_name;: Switches to the specified database, allowing you to perform operations within that database.CREATE DATABASE database_name;: Creates a new database with the specified name.CREATE TABLE table_name (column1 datatype, column2 datatype, ...);: Creates a new table with the specified columns and data types.INSERT INTO table_name (column1, column2, ...) VALUES (value1, value2, ...);: Inserts data into the specified table.
These are just a few examples of the commands you can use in the MariaDB shell. The shell provides a comprehensive set of tools for managing your database and executing SQL queries. You can refer to the MariaDB documentation for more information on the available commands and their usage.
