How do you stop a perl Dancer/Starman/Plack server?

Question

I started a Dancer/Starman server using:

sudo plackup -s Starman -p 5001 -E deployment --workers=10 -a mywebapp/bin/app.pl

but I'm unsure how I can stop the server. Can someone provide me with a quick way of stopping it and all the workers it has spawned?

Why `sudo`? Do you really need to run this thing as root? – innaM Jun 22 '13 at 11:08 — innaM, Jun 22 '13 at 11:08
Good question... probably not! :) – Vijay Boyapati Jun 22 '13 at 22:44 — Vijay Boyapati, Jun 22 '13 at 22:44

Use the

--pid /path/to/the/pid.file

and you can kill the process based on his PID

So, using the above options, you can use

kill $(cat /path/to/the/pid.file)

the pid.file simply stores the master's PID - don't need analyze the ps output...

I killed the process, but now I can't restart it using plackup. It says there's still a server running on that port – Vijay Boyapati Jun 17 '13 at 21:42

don't use `kill -9`, but simple `kill`. Now manually remove the pid-file. The `kill -9` doesn't closes opened sockets and so on... – clt60 Jun 17 '13 at 21:44
Oops :( So I already used kill -9. Anyway to recover? Also, where do I find the pid-file? None was specified at startup. And the process seems to be continuing to serve requests on port 5001, even tho I killed it with kill -9! – Vijay Boyapati Jun 17 '13 at 21:45
if pid file is not specified, here in no one. The recover depends on your system (i hope) - maybe after some timeout the sockets closes - but im not sure. Bad habit using `kill -9` for all things... :) – clt60 Jun 17 '13 at 21:48
Thanks jm666 - good to know. Maybe I'll try a reboot and see if the pesky Starman job will die. It's weird tho that I can't even see it with a ps. Hardy little process! – Vijay Boyapati Jun 17 '13 at 21:55

use `lsof -i:5001` (or maybe `sudo lsof -i:5001`) to find which processes are serving that port – mob Jun 17 '13 at 22:10

On Windows you can do "CTRL + C" like making a copy but Cancel in this case. Tested working.

The OP's usage of `sudo` implies that he's on Linux (or Unix in general). CTRL+C works there as well _if_ the server runs in foreground. But I think the question was about stopping the server _with a command_. – PerlDuck Jun 23 '17 at 10:58
