Phusion Passenger ngnix.conf location

I have a Rails 3 application that uses Phusion Passenger. I install the standalone version of Passenger usin开发者_Python百科g the command "gem install passenger" on my Macintosh MacBook Pro. The application works fine. Now, I want to change some configurations for the ngnix server but I can not find the location of the ngnix.conf file. I have looked in /usr/local and /opt/ and /etc/. Can someone assist me in either finding or creating the ngnix.conf?

Thanks

Look for the nginx.conf file in /opt/nginx/conf

You must have su privileges to edit this file.

Remember to stop and start nginx after making your changes
