　　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: y
　　There are three levels of password validation policy:
　　LOW    Length >= 8
　　MEDIUM Length >= 8, numeric, mixed case, and special characters
　　STRONG Length >= 8, numeric, mixed case, special characters and dictionary                  file
　　Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 2
　　Using existing password for root.
　　Estimated strength of the password: 25
　　Change the password for root ? ((Press y|Y for Yes, any other key for No) : y

　　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) : y
　　Success.
　　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) : y
　　- Dropping test database...
　　Success.
　　- Removing privileges on test database...
　　Success.
　　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!
