MySQL : A little security tip

In this article I am going to show you a little trick about MySQL ,which might help you to prevent some attack on production database server.Every MySQL server has a root user attached to it and for intruders it's very easy to guess that and launch attack on it.

Here is how you can change the root user name for that MySQL server :


bhaskar@bhaskar-laptop_08:55:51_Thu Jan 13:~> sudo mysql -u root -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 26
Server version: 5.1.51-log Gentoo Linux mysql-5.1.51

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql>use mysql;
mysql> update user set password=PASSWORD("NEWPASSWORD") where
User='';
mysql> flush privileges;
mysql> quit


That's all!!

Hope this will help.

Cheers!
