Python——Window启动服务

一、新建启动服务程序

# ZPF
# encoding=utf-8
import win32timezone
from logging.handlers import TimedRotatingFileHandler
import win32serviceutil
import win32service
import win32event
import os
import logging
import inspect
import time
import shutil

class PythonService(win32serviceutil.ServiceFramework):
    _svc_name_ = "PythonService"                    #服务名
    _svc_display_name_ = "Clearjob"                 #job在windows services上显示的名字
    _svc_description_ = "Clear system files"        #job的描述

    def __init__(self, args):
        win32serviceutil.ServiceFramework.__init__(self, args)
        self.hWaitStop = win32event.CreateEvent(None, 0, 0, None)
        self.logger = self._getLogger()
        #启动文件的地址
        #cmd命令self.path = os.popen("python manage.py runserver IP:端口")
        self.path = 'D:\\WebSite'
        self.T = time.time()
        self.run = True

    def _getLogger(self):
        '''日志记录'''
        logger = logging.getLogger('[PythonService]')
        this_file = inspect.getfile(inspect.currentframe())
        dirpath = os.path.abspath(os.path.dirname(this_file))
        if os.path.isdir('%s\\log'%dirpath):  #创建log文件夹
            pass
        else:
            os.mkdir('%s\\log'%dirpath)
        dir = '%s\\log' % dirpath

        handler = TimedRotatingFileHandler(os.path.join(dir, "Clearjob.log"),when="midnight",interval=1,backupCount=20)
        formatter = logging.Formatter('%(asctime)s %(name)-12s %(levelname)-8s %(message)s')
        handler.setFormatter(formatter)
        logger.addHandler(handler)
        logger.setLevel(logging.INFO)

        return logger

    def SvcDoRun(self):
        self.logger.info("service is run....")
        try:
            while self.run:
                self.logger.info('---Begin---')
                for path, name, file in os.walk('D:\\Website'):
                    if path == 'D:\\Website':
                        for IISname in name:
                            floder = []
                            for i in os.listdir(os.path.join(path, IISname)):
                                if i.isdigit():
                                    floder.append(int(i))
                            if len(floder) == 0:
                                pass
                            elif len(floder) >= 2:  # 设置保留备份
                                floder.sort()
                                for x in floder[:(len(floder) - 2)]:
                                    self.logger.info("delete dir: %s" % os.path.join(os.path.join(path, IISname), str(x)))
                                    shutil.rmtree(os.path.join(os.path.join(path, IISname), str(x)))

                self.logger.info('---End---')
                time.sleep(10)

        except Exception as e:
            self.logger.info(e)
            time.sleep(60)

    def SvcStop(self):
        self.logger.info("service is stop....")
        self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)
        win32event.SetEvent(self.hWaitStop)
        self.run = False

if __name__ == '__main__':
    win32serviceutil.HandleCommandLine(PythonService)

二、将服务安装到windows

#安装服务
python Clearjob.py install

#开启服务
python Clearjob.py start

#停止服务
python Clearjob.py stop

#移除服务
python Clearjob.py remove

三、异常解决方法

1.开启服务的时候会出现报错“The service did not respond to the start or control request in a timely fashion”，意思是“服务没有及时响应启动或控制请求”。

2.解决方案：将Python36\Lib\site-packages\win32路径下的pythonservice.exe注册一下。

注册命令：pythonservice.exe /register

3.这很尴尬。。。缺少pywintypes36.dll。找下，在Python36\Lib\site-packages\pywin32_system32路径。

解决方法：设置到环境变量或者将此dll copy到Python36\Lib\site-packages\win32。

注册完后执行python Clearjob.py start

服务运行成功！
