python程序后台运行的实现

后台运行work()方法。

work.py

 1 # -*- coding:utf-8 -*-
 2 
 3 def work():
 4     print "running"
 5     import time
 6     time.sleep(100)
 7 
 8 
 9 if __name__ == '__main__':
10     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

1 # -*- coding:utf-8 -*-
2 
3 import daemon
4 from work import work
5 with daemon.DaemonContext():
6     work()

运行

python use_daemon.py
