Question

I started a “rails server” in my Mac OS X terminal. Supposedly if I just hit Ctrl+c in that terminal, I can shut it down. But I accidentally closed the terminal and now I can’t shut it down.

I started another test project and try “rails server” again, and I got

Address already in use – bind(2) (Errno::EADDRINUSE)” error.

Can anyone help?

You can use killall -9 rails to kill all running apps with “rails” in the name.

The app should have died when the window closed though I have seen Ruby and/or Rails apps stick. You can have the system tell you if any “ruby” or “rails” apps are running with one of these commands:

ps auxw | grep ruby
ps auxw | grep rails`

This is the output of the first one:

greg     14461   0.3  0.7  2483432  15000 s001  S+   10:10PM   1:03.43 /Users/greg/.rvm/rubies/ruby-1.9.2-p0/bin/ruby script/rails c

You can see the path to the running app which will help identify the job. The number in the second column is the process ID. kill -9 14461 would kill it. Or, like above the killall command will do it by searching for apps with rails in the name.
