After completing these steps, MySQL will be successfully installed on your Debian 12 system. You can now proceed to the next step to start and enable the MySQL server.

Important Note:

During the installation process, it's essential to keep your root password secure and confidential. This password grants you full access to your MySQL server, so make sure to choose a strong password and store it in a safe place.

Step 4: Start and Enable the MySQL Server

Now that you have successfully installed MySQL on Debian 12, it's time to start and enable the MySQL server. This will allow you to start using MySQL and managing your databases on your Debian 12 system.

To start the MySQL server, open your terminal and enter the following command:

sudo systemctl enable --now mysql

This command will launch and enable the MySQL service on your Debian 12 system. Once the service is enabled, it will automatically start whenever your system boots up.

To check the status of the MySQL service, use the following command:

sudo systemctl status mysql

This command will display the current status of the MySQL service, including whether it is running or not. If the service is running, you can proceed to log in to your MySQL server and start managing your databases.

Step 5: How to Secure the MySQL Database Server

Securing your MySQL database server is crucial to protect your data from unauthorized access and potential security threats. Follow these steps to ensure the security of your MySQL installation on Debian 12:

1. Run the MySQL Secure Installation Script: Start by running the MySQL secure installation script using the command sudo mysql_secure_installation. This script will guide you through various security-related configurations, such as disabling anonymous user access, removing test databases, and disallowing remote root login.
2. Set a Strong Root Password: During the MySQL secure installation script, you will be prompted to set a new password for the MySQL root user. Be sure to choose a strong password that includes a combination of uppercase and lowercase letters, numbers, and special characters. This will help prevent unauthorized access to your database server.
3. Restrict Remote Access: By default, MySQL allows access from any remote host. To enhance security, consider restricting remote access to specific IP addresses or networks. You can do this by modifying the MySQL configuration file (/etc/mysql/mysql.conf.d/mysqld.cnf) and adding bind-address = your_server_ip. Restart the MySQL service for the changes to take effect.
4. Regularly Update MySQL: Stay updated with the latest version of MySQL to benefit from security patches and bug fixes. Regularly check for updates and apply them to keep your MySQL installation secure.

By following these steps, you can significantly enhance the security of your MySQL database server on Debian 12.

Step 6: Login to Your MySQL Server

Now that you have successfully installed and secured MySQL on Debian 12, it's time to log in to your MySQL server and start managing your databases. Logging in to MySQL server on Debian 12 is a straightforward process that can be done using the command line interface.

To log in to your MySQL server, open a terminal window and enter the following command:

mysql -u root -p

This command instructs MySQL to log in as the root user with the "-u root" option. The "-p" option prompts you to enter the root password, ensuring secure access to your MySQL server.

Once you enter the command, you will be prompted to enter your root password. After successful authentication, you will be greeted with the MySQL command-line interface, where you can execute various commands and manage your databases.

Accessing MySQL Server on Debian 12

Logging in to your MySQL server grants you access to a powerful tool for managing your databases. With the MySQL command-line interface, you can create databases, manage users, change privileges, and perform other administrative tasks.

For example, you can create a new database using the following command:

CREATE DATABASE mydatabase;
