Securing the MySQL server deployment.

Connecting to MySQL using a blank password.

VALIDATE PASSWORD PLUGIN can be used to test passwords  
and improve security. It checks the strength of password  
and allows the users to set only those passwords which are  
secure enough. Would you like to setup VALIDATE PASSWORD plugin?

Press y|Y for Yes, any other key for No: N  
Please set the password for root here.

New password:

Re-enter new password:  
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) : N

... skipping.

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) : Y  
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) : N

... skipping.  
Reloading the privilege tables will ensure that all changes  
made so far will take effect immediately.

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

All done!
