Re: Running application using cherryd

After a lot of trial and error and some research I came to following most 
simple solution.

I use Ubuntu 16.04 which by default uses systemd. So the solution is to 
create a systemd service. Advantage being that you do not need any 
daemonizing or forking.

In 

/lib/systemd/system 

create a file called cherrypy.service (or whatever you want to call it). 
Add to that file following info:

    [Unit]
    Description=Cherrypy Web Server

    [Service]
    Type=simple
    WorkingDirectory=/path/to/cwd
    ExecStart=/path/to/cherrpy/script.py

    [Install]
    WantedBy=multi-user.target

Run commands:

sudo systemctl daemon-reload
sudo systemctl enable cherrypy.service

If you now reboot your cherrypy application should start automatically at 
boot.

You can manually start/stop the service with

sudo systemctl start cherrypy
sudo systemctl stop cherrypy

You do not need to add any daemonzing code to your application.
An interesting "trick" is to add 

#!/path/to/virtualenv/bin/python

to the top of your script/application file. This way your desired 
virtualenv is used for running the script

Hope this helps other people new to this to get this up and running quick 
and simple.
