Step 5: Secure MariaDB Install

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current password for the root user. If you've just installed MariaDB, and you haven't set the root password yet, the password will be blank, so you should just press enter here.

Enter current password for root (enter for none): OK, successfully used password, moving on…

Setting the root password ensures that nobody can log into the MariaDB root user without the proper authorization.

Set root password? [Y/n] y New password: Re-enter new password: Password updated successfully! Reloading privilege tables.. … Success!

By default, a MariaDB installation has an anonymous user, allowing anyone to log into MariaDB without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment.

Remove anonymous users? [Y/n] y … Success!

Normally, root should only be allowed to connect from the 'localhost'. This ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] y … Success!

By default, MariaDB comes with a database named 'test' that anyone can access. This is also intended only for testing and should be removed before moving into a production environment.

Remove test database and access to it? [Y/n] y
