Improve mysql installation security
mysql_secure_installation
This program enables you to improve the security of your MySQL installation in the following ways:
You can set a password for root accounts.
You can remove root accounts that are accessible from outside the local host.
You can remove anonymous-user accounts.
You can remove the test database (which by default can be accessed by all users, even anonymous users), and privileges that permit anyone to access databases with names that start with test_.
mysql_secure_installation helps you implement security recommendations similar to those described at Section 2.10.4, “Securing the Initial MySQL Accounts”.
Invoke mysql_secure_installation without arguments:
shell> mysql_secure_installation
When executed, the script prompts you to determine which actions to perform.
