Deiman is a Python utility class for daemonizing a process. It has start and stop methods as well as a method for retrieving a process status information. It can also detect stale PIDs and remove them.
Deiman uses the Unix double fork method to push the process to the background.
Linux/Unix only, untested on Mac OS.
pip install deiman
pip install -e git+git://github.com/kura/deiman.git#egg=deiman
Download the latest tarball from PyPI or GitHub. Unpack and run:
python setup.py install
To use Deiman, you simply need to import the main Deiman class, passing a path to where you want the pid to be stored and call the start and stop methods as required
from deiman import Deiman
d = Deiman("/tmp/a.pid")
print "This print will be hidden because I am daemonized"
