摘要: windows上如果想執行一些常駐進程，使用python需要打開終端，容易誤操作關掉。本文介紹一種在后臺啟動的解決方法，其實核心功能很簡單，使用 start pythonw xxx.py 進行，附加一些常用的運維批處理腳本 start.bat stop.bat restart.bat status.bat

1.使用start pythonw xxx.py可在機器上執行python但隱藏終端，通常日志來查問題

2.使用ping實現sleep操作，避免使用pause導致的交互問題

app.py

import?os import?time import?datetimepid?=?os.getpid()fp?=?file("app.pid",?"wt") fp.write("%d"?%?pid) fp.close()while?True:time.sleep(1)fp?=?file("app.log","at")fp.write("%s\n"?%?datetime.datetime.now())fp.close()

start.bat

@echo?off if?exist?app.pid?(echo?"[%date%?%time%]?Running.." ping?-n?3?localhost?>nul exit )else?(?echo?"[%date%?%time%]?Starting.." start?pythonw?app.py ping?-n?3?localhost?>nul status.bat ping?-n?3?localhost?>nul )

stop.bat

@echo?offif?exist?app.pid?(echo?"[%date%?%time%]?Stopping..."python?-c?"import?os;?os.system('taskkill?/F?/PID?%%s'?%%?open('app.pid').read());"del?app.pid )else?(echo?"[%date%?%time%]?Stopped.." ping?-n?3?localhost?>nul )

status.bat

@echo?off if?exist?app.pid?(echo?"[%date%?%time%]?Runningg...")else?(echo?"[%date%?%time%]?Stopped..") ping?-n?3?localhost?>nul

restart.bat

@echo?off if?exist?app.pid?(echo?"[%date%?%time%]?Stopping..."python?-c?"import?os;?os.system('taskkill?/F?/PID?%%s'?%%?open('app.pid').read());"del?app.pid )else?(echo?"[%date%?%time%]?Stopped.." ping?-n?3?localhost?>nul )if?exist?app.pid?(echo?"[%date%?%time%]?Running.." ping?-n?3?localhost?>nul exit )else?(?echo?"[%date%?%time%]?Starting.." start?pythonw?app.py ping?-n?3?localhost?>nul status.bat ping?-n?3?localhost?>nul )
