Lightweight and no-nonsense POSIX daemon library for Python (2.x.x/3.x.x)

Project description

Daemonator (0.4.1.1) Formerly Daemon-Python
==================

Lightweight and no-nonsense POSIX daemon library. Extensible, complete
with process forking and
`PID <http://en.wikipedia.org/wiki/Process_identifier>`__ management.

Inspired by `Sander
Marechal <http://www.jejik.com/articles/2007/02/a_simple_unix_linux_daemon_in_python/>`__.

Getting Started
---------------

**Installation**

::

# git clone https://github.com/flaviocpontes/daemonator.git
# cd daemon-py/
# python setup.py install

1. **Instantiation**

::

import daemon
class MyDaemon(daemon.Daemon):
"""Subclass Daemon-Python."""
...
def run(self):
"""Define what to daemonize by implementing the run() method."""
...

2. **Implementing control**

Finally, we want to be able to control our daemon.

::

...
if __name__ == "__main__":
daemon = MyDaemon('/tmp/mydaemon.pid') #Define a pidfile location (typically located in /tmp or /var/run)
if len(sys.argv) == 2:
if 'start' == sys.argv[1]:
daemon.start()
elif 'stop' == sys.argv[1]:
daemon.stop()
elif 'restart' == sys.argv[1]:
daemon.restart()
elif 'status' == sys.argv[1]:
daemon.status()
else:
sys.stdout.write("Unknown command\n")
sys.exit(2)
sys.exit(0)
else:
sys.stdout.write("Usage: %s start|stop|restart|status\n" % sys.argv[0])
sys.exit(2)
