SimpleDaemon

A fork of Shane Hathaway's daemon.py script.

Features

  • 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

Example

Writing a daemon requires creating two files, a daemon file and a configuration file with the same name.

hellodaemon.py:

import simpledaemon
import logging
import time

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

    def run(self):
        while True:
            logging.info('The daemon says hello')
            time.sleep(1)

if __name__ == '__main__':
    HelloDaemon().main()

hellodaemon.conf:

[hello]
uid =
gid =
pidfile = ./hellodaemon.pid
logfile = ./hellodaemon.log
loglevel = info
