1、想写一个监视服务器是否运行的简单服务，网上搜到的例程不太完善，如梅劲松的许久

没有更新，而且SvcDoRun写得不完整（见http://www.chinaunix.net/jh/55/558190.html，

不知道是不是原始出处）；而mail.python.org中的没有定义_svc_name_等变量（见

http://mail.python.org/pipermail/python-list/2005-December/315190.html）

2、这个实现功能很简单，就是把当前时间写入‘c:\\temp\\time.txt’文件，一看即知，

大家可以随意扩充。

3、用

service install 安装

service start 启动

service stop 停止

service debug 调试

service remove 删除

service.py

---代码开始

#coding:utf-8

import win32serviceutil

import win32service

import win32event

import win32evtlogutil

import time

class service(win32serviceutil.ServiceFramework):

_svc_name_ = "test_python"

_svc_display_name_ = "test_python"

def __init__(self, args):

win32serviceutil.ServiceFramework.__init__(self, args)

self.hWaitStop = win32event.CreateEvent(None, 0, 0, None)

print '服务开始'

def SvcDoRun(self):

import servicemanager

#------------------------------------------------------

# Make entry in the event log that this service started

#------------------------------------------------------

servicemanager.LogMsg(servicemanager.EVENTLOG_INFORMATION_TYPE,servicemanager.PYS_SERVICE_STARTED,(self._svc_name_,''))

#-------------------------------------------------------------

# Set an amount of time to wait (in milliseconds) betweenruns

#-------------------------------------------------------------

self.timeout=100

while 1:

#-------------------------------------------------------

# Wait for service stop signal, if I timeout, loop again

#-------------------------------------------------------

rc=win32event.WaitForSingleObject(self.hWaitStop,self.timeout)

#

# Check to see if self.hWaitStop happened

#

if rc == win32event.WAIT_OBJECT_0:

#

# Stop signal encountered

#

break

else:

#

# Put your code here

#

#

f=open('c:\\temp\\time.txt','w',0)

f.write(time.ctime(time.time()))

f.close()

print '服务运行中'

time.sleep(1)

#

# Only return from SvcDoRun when you wish to stop

#

return

def SvcStop(self):

#---------------------------------------------------------------------

# Before we do anything, tell SCM we are starting the stopprocess.

#---------------------------------------------------------------------

self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)

#---------------------------------------------------------------------

# And set my event

#---------------------------------------------------------------------

win32event.SetEvent(self.hWaitStop)

print '服务结束'

return

if __name__=='__main__':

win32serviceutil.HandleCommandLine(service)
