How to change the mysql root password

Question

I have installed MySQL server 5 on redhat linux. I can\'t login as root so I can\'t change the root password.

mysql -u root -p  
Enter password:  

        

Answer 1

The root user password is an empty string by default.

And (using password: NO) says that there is no password.

Do you try to login from another system? I imagine you can only login as root user locally.
