I am using a ssh to run the command, after it I have to log off. I find after some time the process is exited. I suspect it's Linux send some signal to it? I think if I can make the daemon then I can avoid this?

我正在使用ssh运行这个命令，在它之后我必须注销。我怀疑是Linux给它发送信号?我想如果我能做这个守护进程我就能避免这个?

Although nohup will work, it's a quick and dirty solution. To make a proper daemon process you need to use SysV init or (If you are running Ubuntu 6.10+ or Fedora 9+) upstart.

尽管nohup是有效的，但它是一个快速而肮脏的解决方案。要做一个适当的守护进程，您需要使用SysV init或(如果运行Ubuntu 6.10+或Fedora 9+) upstart。

Here's a simple script that starts a.py and restarts it whenever it gets killed (up to 5 times inside a 5 minute span):

下面是一个启动a的简单脚本。当它被杀死时(在5分钟内最多5次)，就重新启动:

respawn

respawn limit 5 300

exec python /path/to/a.py

Then just put that script in /etc/init/.

然后把这个脚本放到/etc/init/中。

Upstart has a lot more options too. Checkout the Quick Start tutorial.
