Increase MYsql file size Upload

[betatester3.0]

Also can you tell me method to install my db via ssh so it gets to phpmyadmin and works with my website files? I am asking as I think it's much easier and faster to upload via ssh. 

And cpanel allows db_user to be like db_12442 but sentora only allows "xxxxxxx" without any prefix, so do i have to make any changes in my db so that it can be uploaded and works properly, if so, how do i achieve it?

Add your domain name, create a database using the db module, create a user for the database created. login using the new user credentials then simply import your db.sql file
