Python Windows Service开发

注意要import script文件

另外script文件中的方法不要有控制台打印输出

 

'''
 Usage : python resartHubService.py install
 Usage : python resartHubService.py start
 Usage : python resartHubService.py stop
 Usage : python resartHubService.py remove

# Done! Lets go out and get some dinner, bitches!

 

 这里我调用的是一个Cron Job，所以没有使用while 1的loop，而是直接调用

service = RestartHub()

service.restartHubMain()

并且需要处理service stop的信号，service.stopJob()

 

这是job的代码：

def restartHubMain(self):
		self.write(self.hostname)
		self.scheduler = Scheduler(daemonic = False)
		self.scheduler.start()
		job = self.scheduler.add_cron_job(self.restartService,day_of_week=self.day_of_week,hour=self.hour,minute=self.minute,second=self.second)


	def stopJob(self):
		self.scheduler.shutdown()
