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 currentpassword for the root user. If you've just installed MariaDB,
andhaven't set the root password yet, you should just press enter here.
Enter current password for root (enter for none):
successfully used password, moving on...
Setting the root password or using the unix_socket ensures that nobodycan log into the MariaDB root user without the proper authorisation.
You already have your root account protected, so you can safely answer 'n'.
Switch to unix_socket authentication [Y/n] n
... skipping.You already have your root account protected, so you can safely answer 'n'.
Change the root password? [Y/n] y
Re-enter new password:
Password updated successfully!
Reloading privilege tables.....
By default, a MariaDB installation has an anonymous user, allowing anyoneto log into MariaDB without having to have a user account created for
them.This is intended only for testing, and to make the installationgo a bit smoother.
You should remove them before moving into aproduction environment.
Remove anonymous users? [Y/n] y
Normally, root should only be allowed to connect from 'localhost'.Thisensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] y...
MariaDB comes with a database named 'test' that anyone canaccess.This is also intended only for testing, and should be removedbefore moving into
a production environment.Remove test database and access to it? [Y/n] y
- Dropping test database...... Success!
- Removing privileges on test database...... Success!
Reloading the privilege tables will ensure that all changes made so farwill take effect immediately.Reload privilege tables now? [Y/n] y
Cleaning up...All done!If you've completed all of the above steps, your MariaDBinstallation should now be secure.Thanks for using MariaDB!
