Provides a simple Daemon class to ease the process of forking a python application on Unix systems.

Project Description

A fork of Shane Hathaway’s script.


  • reads the command line
  • reads a configuration file
  • configures logging
  • calls root-level setup code
  • drops privileges
  • calls user-level setup code
  • detaches from the controlling terminal
  • checks and writes a pidfile


pip install simpledaemon


Writing a daemon requires creating two files, a daemon file which simply enters an infinite loop and does whatever you want it to do, and a configuration file with the same name which tells simpledaemon how to setup your daemon.

import simpledaemon
import logging
import time

class HelloDaemon(simpledaemon.Daemon):
    default_conf = '/etc/hellodaemon.conf'
    section = 'hello'

    def run(self):
        while True:
  'The daemon says hello')

if __name__ == '__main__':


pidfile = ./
logfile = ./hellodaemon.log
loglevel = info


To use your new daemon, execute your script like so:

./ --start

Stopping is similar:

./ --stop

For a full list of options, see the help:

./ --help
