Deploying a Ruby on Rails application: an example

Suppose you have a Ruby on Rails application in /somewhere. Add a server block
to your Nginx configuration file, set its root to /somewhere/public, and set
'passenger_enabled on', like this:

   server {
      listen 80;
      server_name www.yourhost.com;
      root /somewhere/public;   # <--- be sure to point to 'public'!
      passenger_enabled on;
   }

And that's it! You may also want to check the Users Guide for security and
optimization tips and other useful information:

  /usr/local/lib/ruby/gems/1.8/gems/passenger-2.2.14/doc/Users guide Nginx.html
