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):

Prompt for password, no password to enter directly

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]

Prompt to set root user password Y

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]

... 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.

Disable root user telnet to Y

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]
