Best Practices for Configuring ​Two-Factor ⁢Authentication‌ for MariaDB on CentOS 8

Best Practices for Configuring Two-Factor Authentication⁤ for MariaDB on CentOS 8

Configuring two-factor authentication ‌(2FA) for MariaDB on⁤ CentOS 8 is an essential security measure that⁤ helps protect ⁢your database from⁤ unauthorized access. By ⁤adding an extra layer of ⁢authentication, you significantly enhance the security of your MariaDB installation. In this tutorial, we will walk you through the‍ best practices for configuring 2FA on ⁤MariaDB running⁢ on CentOS 8.

To​ start, ensure that you have MariaDB ⁣installed on ‌your CentOS 8 system. ​If not, you‌ can install ​it by running the‌ following commands in your terminal:

$ sudo dnf install mariadb-server

$ sudo systemctl start mariadb

$ sudo systemctl enable mariadb

Once MariaDB⁢ is up and running, the next step is to enable the 2FA plugin. Begin by logging into your MariaDB server using⁤ the root⁣ account:

$ sudo mysql -u root -p

After entering the root‌ password, execute the following SQL⁢ command to install and enable the⁢ plugin:

MariaDB [(none)]> INSTALL PLUGIN two_factor SONAME '';

Now that the 2FA plugin is installed, we need ⁤to create a separate user account that will be required to use 2FA for authentication. ⁢Run the following SQL command to create a new user with 2FA enabled:

MariaDB [(none)]> CREATE USER 'myuser'@'localhost' REQUIRE TWO_FACTOR;

Make sure to replace ‘myuser’ with the desired username for your MariaDB account. With the new user ⁣created,⁣ you can exit the ⁣MariaDB shell using the ​ quit command.

Next, we⁢ need to generate a secret ​key for the 2FA authentication. Open your terminal and run the following command:

$ otputil show myuser

This​ command will generate a QR code and display​ the secret key in your⁢ terminal. To proceed, you need to install a QR code reader ⁣application on your⁢ mobile device or use​ an online‌ QR code reader. Scan ‌the QR‌ code or manually enter the secret key ⁤into the 2FA ‌authentication app of your choice.

Finally, to complete the configuration, we need to ‌modify the MariaDB‌ configuration file. Open the file /etc/my.cnf.d/mariadb-server.cnf with a text ⁤editor and add the following two lines under the [mysqld] ⁣section:

plugin_load_add =
plugin_dir = /usr/lib64/mysql/plugin/

Save the changes and restart the MariaDB ⁤service using the ​following command:

$ sudo systemctl restart mariadb

Congratulations!‍ You have successfully configured two-factor authentication for MariaDB on CentOS ‌8. ⁤From now on, ⁢any user account created⁤ with 2FA enabled will require the OTP code in addition to the password for authentication. This adds an extra layer of security to your MariaDB database, protecting it ‍from‍ unauthorized access.
