By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL 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? (Press y|Y for Yes, any other key for No) :

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? (Press y|Y for Yes, any other key for No) :
Success.


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) :
