How to shutdown CherryPy

Question

I created the following function to shutdown cherrypy:

import cherrypy
cherrypy.engine.exit()

Name of the file: shutdown.py. And then I enter the command python shutdown.py in the command line. The following messages showed up:

[06/Sep/2014:11:28:22] ENGINE Bus STOPPING
[06/Sep/2014:11:28:22] ENGINE HTTP Server None already shut down
[06/Sep/2014:11:28:22] ENGINE No thread running for None.
[06/Sep/2014:11:28:22] ENGINE No thread running for None.
[06/Sep/2014:11:28:22] ENGINE Bus STOPPED
[06/Sep/2014:11:28:22] ENGINE Bus EXITING
[06/Sep/2014:11:28:22] ENGINE Bus EXITED

However, CherryPy is still running. How do I shutdown CherryPy then?

Also, what if I have multiple cherrypy servers running at the same time? Does the shutdown.py kill all of them?

Which OS are you running? You need to use signals to kill another process. There is no global cherrypy server. — cyraxjoe, Sep 06 '14 at 05:36

CherryPy application is contained in ordinary Python process. To treat CherryPy application like a server (e.g. mysql, nginx, etc. which you can /etc/init.d/mysql stop) you should deploy it accordingly.

For an ad-hoc case, just tell cherryd to save pid file with --pidfile or integrate PIDFile plugin into your code directly. Then just kill `cat /path/to/pidfile`.

For a full-blown deployment read this answer.

Thanks, but I used the `server.py` to start cherrypy as provided by this tutorial (https://www.digitalocean.com/community/tutorials/how-to-deploy-python-wsgi-applications-using-a-cherrypy-web-server-behind-nginx). How can obtain the process id of cherrypy? – Randy Tang Sep 08 '14 at 13:13
I've already told you -- use PIDFile plugin. Something like ``plugins.PIDFile(engine, '/run/yourapp/yourapp.pid').subscribe()``. Take a look at [cherryd source](https://bitbucket.org/cherrypy/cherrypy/src/2a045705a5e403699aab915ab32ea8484f259fa1/cherrypy/cherryd?at=default#cl-39) for the context. – saaj Sep 08 '14 at 15:06

This question is 6 years ago, but I want to answer something important. The best way to shutdown Cherrypy server is setting the following configuration in your code:

cherrypy.config.update({ 'server.shutdown_timeout': 1 })

Of this way you are sure the server is shutdown, you can see more about that in this issue. So, I hope this can help someone.
