Nginx/Passenger/Rails, where to set RAILS_ENV?

Question

I've deployed my site to its testing location, but I'm not sure where I set what the RAILS_ENV should be for this server. Where should I look?

Answer 1

You can use rack_env directive to set the rails env as described here in passenger for nginx documentation

6.16. Rack and Rails >= 3 specific options

If you are on rails 1.x or 2.x, you can use rails_env directive

Answer 2

Short Answer: passenger_app_env development;

Sets: RAILS_ENV RACK_ENV WSGI_ENV NODE_ENV PASSENGER_APP_ENV

Example nginx conf:

    http {
    passenger_root /home/user/.rvm/gems/ruby-2.1.0@app/gems/passenger-4.0.29;
    passenger_ruby /home/user/.rvm/wrappers/ruby-2.1.0@app/ruby;
    passenger_app_env development;
}
