You should remove them before moving into a production
environment.Remove anonymous users? (Press y|Y for Yes, any other key for No) : Y
Success.Normally, root should only be allowed to connect from

the root password from the network.Disallow root login remotely? (Press y|Y for Yes, any other key for No) : N... skipping.
By default, MySQL 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? (Press y|Y for Yes, any other key for No) : N... skipping.
Reloading the privilege tables will ensure that all changes
