问题描述
我从 python 脚本中生成 5 个不同的进程，如下所示:
I'm spawning 5 different processes from a python script, like this:
p = multiprocessing.Process(target=some_method,args=(arg,)) p.start()
我的问题是，当父进程(主脚本)以某种方式被杀死时，子进程继续运行.
My problem is, when, somehow the parent process (the main script) gets killed, the child processes keeps on running.
当父进程被杀死时，有没有办法杀死像这样产生的子进程?
Is there a way to kill child processes, which are spawned like this, when the parent gets killed ?
我正在尝试这个:
p = multiprocessing.Process(target=client.start,args=(self.query_interval,)) p.start() atexit.register(p.terminate)
但这似乎不起作用
推荐答案
我自己也遇到过同样的问题，我的解决方法如下:
I've encounter the same problem myself, I've got the following solution:
在调用p.start()之前，你可以设置p.daemon=True.然后在这里提到 python.org 多处理
before calling p.start(), you may set p.daemon=True. Then as mentioned here python.org multiprocessing
当一个进程退出时，它会尝试终止其所有守护进程.
When a process exits, it attempts to terminate all of its daemonic child processes.
