Restarting a rails app on shared hosting

Posted in

I don't work in Rails very much these days, so when I do go back to it I get frustrated that I've forgotten even the most basic principles and techniques.

If you've made tweaks to a Rails app and need to reload the cached version of the site, use the following commands to first find the process id (pid) of the dispatch.fcgi job, then kill that process:

  1. ps aux | grep ruby
  2. kill -USR2 [pid]
