I'm using Ubuntu 14.04. I found the install script, and I've got basic nginx functioning, but the passenger part is not working. I'm serving several web sites, and the ones that don't use passenger are now functioning, but when I visit a URL that should give me a rails application, I get no response, and I don't see any errors in the error log. I see messages indicating that Passenger watchdog is starting and stopping.
I'm using the same nginx server config files that I was using before, and Passenger appears to be listening, but for some reason the requests are not be passed from nginx to Passenger. I get an empty response error page in my browser.
Thanks so much for your help.
