Enter password for user root:

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!
