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:Python27Scripts;C:Python27;C:Python27chromedriver.exe;C:Python27Libsite-packageswin32;C:Python27Libsite-packagespywin32_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

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

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：
