WHM Login and SQL Server conflict

[deo_hai_van]

Hi,
I had to change my root password the other day. As a result, the SQL server was down. So I had to restart through SSH. As a result, I cannot log into WHM because "The login is invalid". But then when I rebooted the server, I am able to log into WHM (without changing any credentials). But now the SQL Server is down.
Very frustrating. So it seems like one of the two (WHM Login, and SQL Server) can be accessible at a time.
Do you have any idea?

Changing root password does NOT take mySQL server down.
I am changing root passwords in our servers quite often and it has never affected mySQL server in any way.
