How to start cloudforms appliance and access the configuration page when logged in as root user.

Issue

• Working with openstack, I could not access the instance with user admin directly to start the application and working with the openstack console in horizon is not convenient. How can I start the appliance when logged in as
  root user?

• I could ssh to cloudforms as root user but not admin user? why? From root
  user how can I start evm appliance and access configuration page?
