testing, and to make the installation go a bit smoother.
You should remove them before moving into a production
environment.

Remove anonymous users? (Press y|Y for Yes, any other key for No) : yes

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

Success.

By default, MySQL comes with a database named 'test' that
anyone can access. This is also intended only for testing,

environment.

 - Dropping test database...
Success.

 - Removing privileges on test database...
