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
haven’t set the root password yet, you should just press enter here.
Enter current password for root (enter for none): << Just press enter
OK, successfully used password, moving on…
Setting the root password or using the unix_socket ensures that nobody
can 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 << Disable Unix Socket Authentication
… skipping.
You already have your root account protected, so you can safely answer ‘n’.
Change the root password? [Y/n] Y << Change Root Password
New password: << Enter Password
Re-enter new password: << Re-Enter 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 << Remove Anonymous Users
… Success!
Normally, root should only be allowed to connect from ‘localhost’. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] Y << Disallow root login remotely
… 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 << Remove test database
Dropping test database…
… Success!
Removing privileges on test database…
… Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] Y << Reload Tables
… Success!
Cleaning up…
All done! If you’ve completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB!
