I have some web applications that I wrote with python flask. I know which port I started each one on and each was started using nohup. Each one was started with something like nohup python mywebapp.py &
When I look at my processes with ps, I only see something like
36697 ? 60-21:36:16 python
36971 ? 63-19:11:43 python
37038 ? 65-06:57:22 python
37312 ? 54-23:33:16 python
37442 ? 54-09:14:57 python
37716 ? 47-19:45:17 python
68019 ? 00:29:24 python
146568 ? 00:20:57 python
146699 ? 00:17:08 python
150622 ? 00:32:20 python
If I need to stop one particular web application, how can I get from a port number back to a python process id so that I can kill the process?

where does the port number get specified when you start(ed) them?
– Jeff Schaller
Jun 26 at 16:21
@JeffSchaller Great question, that is specified within the python code, specifically with a call to start an app server with the flask library/framework.
– Unknown Coder
Jun 26 at 16:25
So the parametermywebapp.pyis enough to determine the port?

You can use lsof to find the process id associated with a known port number
lsof -i :*port*
Alternatively, you may wish to use netstat which can display all network connections, routing tables, interface statistics, masquerade connections, and multicast memberships.
Try netstat -tulpn

This sounds like its along the right track but this server does not have lsof and I cant use apt-get. Are there any other commands similar to this that you would recommend?

if you havenetstatyou may be able to find it usingnetstat -tulpn. You may have to grep the output for it to be useful.

That did it, thank you! I can see the ports and then it gives me the PID in the last column, this is perfect!

One other way is to add it to the flask app itself.
from os import getpid
print("Creating PID file.")
fh=open("/var/run/yourAppNameWithPort.pid", "w")
fh.write(str(getpid()))
fh.close()

You'd add this to you app, it would happen on startup. I usually use argparse and pass in the pidfile name as an argument, but that is just my preference.
