I have Nginx with Passenger. In nginx.conf I have line:
user pass users;
and Nginx process works on \'pass\' user, but Passenger* processe
Put the following into your nginx.conf in the http block:
passenger_default_user custom_username; passenger_default_group custom_group;
You can find more configuration options here:
