Unable to login in gitlab community source install

Hi,

I cannot login to the GUI with the default, username/password of:
root/5iveL!fe
I need to understand how to create a user and assign a password to get into the GUI. gitlab-rails is not installed on the system. It is a basic install from source (I think) following the documentation.

All help will be appreciated. Regards,
