启动一个单独的进程

Starting a separate process(启动一个单独的进程)

问题描述

我想要一个脚本来启动一个新进程，以便在初始脚本退出后新进程继续运行.我希望我可以使用 multiprocessing.Process 来启动一个新进程，并设置 daemon=True 以便主脚本可以在创建的进程继续运行时退出.

I want a script to start a new process, such that the new process continues running after the initial script exits. I expected that I could use multiprocessing.Process to start a new process, and set daemon=True so that the main script may exit while the created process continues running.

但似乎第二个进程在主脚本退出时被静默终止.这是预期的行为，还是我做错了什么?

But it seems that the second process is silently terminated when the main script exits. Is this expected behavior, or am I doing something wrong?

推荐答案

来自 Python 文档:

From the Python docs:

当一个进程退出时，它会尝试终止其所有的恶魔孩子进程.

When a process exits, it attempts to terminate all of its daemonic child processes.

这是预期的行为.
