所需第三方库：python-daemon[https://pypi.python.org/pypi/python-daemon/]

使用方式：

　　python linux_service.py start/stop/restart

from mythings import start
from daemon import runner
import os
import logging
import inspect

class App:

    def __init__(self):
        self.stdin_path = '/dev/null'
        self.stdout_path = '/dev/tty'
        self.stderr_path = '/dev/tty'
        self.pidfile_path = '/tmp/foo.pid'
        self.pidfile_timeout = 5
        self.status = {'alive': True}
        this_file = inspect.getfile(inspect.currentframe())
        current_path = os.path.abspath(os.path.dirname(this_file))
        self.logfile = os.path.join(current_path, 'service.log')

    def _getLogger(self):
        logger = logging.getLogger('[My Service]')
        logger.setLevel(logging.DEBUG)
        fh = logging.FileHandler(self.logfile)
        fh.setLevel(logging.DEBUG)
        #ch = logging.StreamHandler()
        #ch.setLevel(logging.DEBUG)
        formatter = logging.Formatter('%(asctime)s %(name)-12s %(levelname)-8s %(message)s')
        fh.setFormatter(formatter)
        #ch.setFormatter(formatter)
        logger.addHandler(fh)
        #logger.addHandler(ch)
        logger.info('init logger...')
        return logger

    def run(self):
        self.logger = self._getLogger()
        self.logger.info('linux svc do run...')
        start(self.status, self.logger)


app = App()
daemon_runner = runner.DaemonRunner(app)
daemon_runner.do_action()
