NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDEDFOR ALL MariaDB

SERVERS IN PRODUCTION USE! PLEASEREAD 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, thepassword will be blank

So you should just press enter here.

Enter current password for root (enter fornone):

OK, successfully used password, moving on...

Setting the root password ensures thatnobody can log into the MariaDB

Root user without the proper authorisation.

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 ananonymous user, allowing anyone

To log into MariaDB without having to have auser 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 toconnect from 'localhost'. This

Ensures that someone cannot guess at theroot password from the network.

Disallow root login remotely? [Y/n] y

... Success!

By default, MariaDB comes with a databasenamed '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

-Dropping test database...

... Success!

-Removing privileges on test database...

... Success!

Reloading the privilege tables will ensurethat all changes made so far

Will take effect immediately.

Reload privilege tables now? [Y/n] y

... 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!
