Python Daemon Packaging Best Practices

Question

I have a tool which I have written in python and generally should be run as a daemon. What are the best practices for packaging this tool for distribution, particularly how sho

Answer 1

There are many snippets on the internet offering to write a daemon in pure python (no bash scripts)

http://www.jejik.com/articles/2007/02/a_simple_unix_linux_daemon_in_python/ looks clean...

If you want to write your own,
the principle is the same as with the bash daemon function.

Basically:

On start:

• you fork to another process
• open a logfile to redirect your stdout and stderr
• Save the pid somewhere.

On stop:

• You send SIGTERM to the process with pid stored in your pidfile.
• With signal.signal(signal.SIGTERM, sigtermhandler) you can bind a stopping procedure to the SIGTERM signal.

I don't know any widely used package doing this though.
