python程序后台运行的实现

后台运行work()方法。

work.py

 # -*- coding:utf-8 -*-

 def work():
     print "running"
     import time
     time.sleep(100)

 if __name__ == '__main__':
     work()

方法1 使用nohup命令

nohup python work.py >my.log &

方法2 python-daemon

安装python-daemon

pip install python-daemon

编写入口程序

use_daemon.py

 # -*- coding:utf-8 -*-

 import daemon
 from work import work
 with daemon.DaemonContext():
     work()

运行

python use_daemon.py
