Creating a user and granting privileges to the user

Hi All,

This is how the use case goes.

I have to create a new database, a new user and grant privileges to the newly created user for the db which i just created.

The problem is that i am not able to grant the privileges as it says access denied to user.

My first problem:- How do i grant a root access to a user which i created from the dashboard.

If not root user:- How do i get the root credentials to make a new user.
