easy_daemon

Very simple base daemon class. Just override method ‘run’.

Example

#!/usr/bin/env python3

import sys
import time
import logging
from easy_daemon.daemon import Daemon


class ExecDaemon(Daemon):
    def run(self):
        while True:
            self.logger.info('daemon worked')
            time.sleep(5)


if __name__ == "__main__":
    logger = logging.getLogger('very_simple')
    handler = logging.FileHandler('/tmp/very_simple.log', encoding='utf8')
    form = '%(levelname)-10s|%(asctime)s|%(process)d --- %(message)s (%(filename)s:%(lineno)d)'
    handler.setFormatter(logging.Formatter(form))
    logger.addHandler(handler)
    logger.setLevel(level=logging.INFO)
    daemon = ExecDaemon('/tmp/very_simple.pid', logger)
    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()
        else:
            print("Unknown command")
            sys.exit(2)
        sys.exit(0)
    else:
        print("usage: %s start|stop|restart" % sys.argv[0])
        sys.exit(2)
