Note:running all PARTS of this SCRIPT are RECOMMENDED for all MySQL
SERVERS in PRODUCTION use! Please READ each STEP carefully!

In order to log into MySQL to secure it, we'll need the current
Password for the root user. If you ' ve just installed MySQL, and
You haven ' t set the root password yet, the password would be blank,
So, should just press ENTER here.

Enter current password to root (enter for none):
OK, successfully used password, moving on ...

Setting The root password ensures that nobody can log into the MySQL
Root user without the proper authorisation.

Set root Password? [y/n] Y [set root user password]
New Password:
Re-enter new password:
Password Updated successfully!
Reloading privilege tables.
... success!

By default, a MySQL installation have an anonymous user, allowing anyone
To log into MySQL without has to has a user account created for
them. This was intended only for testing, and the installation
Go a bit smoother. You should remove them before moving into a
Production environment.

Remove anonymous users? [y/n] Y [delete anonymous user]
... success!

Normally, Root should only is allowed to connect from ' localhost '. This
Ensures that someone cannot guess at the root of password from the network.

Disallow Root login remotely? [y/n] n [Disable root login]
... skipping.

By default, MySQL comes with a database named ' test ' that anyone can
Access. This was also intended only for testing, and should be removed
Before moving into a production environment.

Remove test database and access to it? [y/n] Y [delete test database]

• Dropping test database ...
  ERROR 1008 (HY000) at line 1:can ' t drop database ' test '; Database doesn ' t exist
  ... failed! Not critical, keep moving ...
• Removing privileges on test database ...
  ... success!

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

Reload privilege tables now? [y/n] Y [UPDATE permissions]
... success!

All done! If you've completed all of the above steps, your MySQL
Installation should now is secure.
