如下遇到自己编写的服务无法启动

需要添加环境变量(标红的)

C:\Python27\Scripts;C:\Python27\;C:\Python27\chromedriver.exe;C:\Python27\Lib\site-packages\win32;C:\Python27\Lib\site-packages\pywin32_system32;

1.需求

为什么要开发一个windows服务呢？之前做一个程序，必须要读取指定目录文件License， 因为其他程序也在读取这指定目录的License文件，且License不同时会修改License的内容，

修改了License后导致我们的程序无法运行，所以想做个windows 的服务时时检测这个License文件是否被修改，如果检测到被修改就覆盖该License。

2.依赖的第三方库

必须要借助第三方模块pywin32

下载地址： https://pypi.python.org/pypi/pywin32/214

3.实现过程

实例化win32serviceutil.ServiceFramework的时候，windows系统会自动调用SvcDoRun方法，

这个函数的执行不可以结束，因为结束就代表服务停止。所以当我们放自己的代码在SvcDoRun函数中执行的时候，必须确保该函数不退出，类似与这样的效果：

1 def SvcDoRun(self):

2 while True:

3 self._LicenseExist()

4 time.sleep(2)

当停止服务的时候，系统会调用SvcDoStop函数，该函数通过设置标志位等方式让SvcDoRun函数退出，就是正常的停止服务。

win32event.SetEvent(self.hWaitStop) 通过事件退出

服务操作命令：

1 #1.安装服务

2

3 python PythonService.py install

4

5 #2.让服务自动启动

6

7 python PythonService.py --startup auto install

8

9 #3.启动服务

10

11 python PythonService.py start

12

13 #4.重启服务

14

15 python PythonService.py restart

16

17 #5.停止服务

18

19 python PythonService.py stop

20

21 #6.删除/卸载服务

22

23 python PythonService.py remove

5.效果与问题

当直接运行py文件访问是可以添加服务，且服务也可运行，但是使用pyinstaller打包exe后程序就不能正常执行，

提示：错误1053 服务没有及时相应启动或控制请求

google 后找到解决方法，

原理我也不是很懂，貌似是要在实例化windows服务类时候，监控服务调度

2 try:

8 if details[0] == winerror.ERROR_FAILED_SERVICE_CONTROLLER_CONNECT:

9 win32serviceutil.usage()

10 else:

11 win32serviceutil.HandleCommandLine(PythonService)

pyinstaller 打包为控制台文件

1 if __name__ == '__main__':

2 from PyInstaller.main import run

3 params=['windows_services_in_python.py', '-F', '-c', '--icon=favicon.ico']

4 run(params)

打包后CMD到改目录：
