nohup

info nohup

‘nohup’ runs the given COMMAND with hangup signals ignored(也就是说,nohup 打头而启动的任务不会被hangup信号挂起,因而得以在后台保持运行(即使您退出了启动任务的shell), so that the command can continue running in the background after you log out.
‘nohup’ does not automatically put the command it runs in the background;
you must do that explicitly, by ending the command line with an &;
需要注意,nohup通常配合&来使用

Also, ‘nohup’ does not alter the niceness of COMMAND; use ‘nice’ for that, e.g., ‘nohup nice COMMAND’.

!!使用命令的别名可能会报错;
某些内建命令也不能够使用nohup来处理

通过ps aux可以看到,manage.py命令已经成为了TTY为?的进程,它的父进程号为1,因之,即使启动manage.py的shell被终止,也不会影响到django服务

启动命令为: nohup py manage.py runserver 0:8080 &

$ psh manage.py
