仅重新启动运行在承载许多乘客应用程序的VPS上的Passenger / nginx上的单个Rails应用程序

Question

I am running multiple rails apps and a sinatra app under the same domain on a VPS using nginx and passenger. When I deploy code I need to restart the application process for the app that got updated. Right now I'm running service nginx stop followed by service nginx start thereby restarting all the passenger processes. It seems silly to have to restart nginx instead of a just the target passenger process. Is there a way to do such a thing?

Here's my nginx.conf file: https://gist.github.com/srt32/8535548 . Thanks.

Goto the root of your Rails application and touch a tmp/restart.txt file.

touch /webapps/mycook/tmp/restart.txt

Remove restart.txt once application is restarted, not mandatory though.
