Answer 4

We can kill rails session on Linux using PORT no

fuser -k 3000/tcp 

here 3000 is a port no. Now restart your server, you will see your server is in running state.

Answer 5

If you are using a more modern version of Rails and it uses Puma as the web server, you can run the following command to find the stuck Puma process:

ps aux | grep puma

It will result in output similar to this:

85923 100.0  0.8  2682420 131324 s004  R+    2:54pm   3:27.92 puma 3.12.0 (tcp://0.0.0.0:3010) [my-app]
92463   0.0  0.0  2458404   1976 s008  S+    3:09pm   0:00.00 grep puma

You want the process that is not referring to grep. In this case, the process ID is 85923.

I can then run the following command to kill that process:

kill -9 85923

Answer 6

killall -9 ruby will kill all the ruby processes, and at-least on my machine, rails servers appear as ruby processes. killall -9 rails is much more specific and doesn't work for older versions of rails servers (it gives a 'rails:no process found' because the process is named ruby)

Encountered this problem a while ago. After submitting a form in activeadmin, the rails server just hanged and I was unable to kill it using normal means (even after ctrl+z it was still running in the background). Learner's answer helped, but this command doesn't need process id.
