杀死使用Python的subprocess.Popen()创建的进程 [英] Killing a process created with Python's subprocess.Popen()

问题描述

这是我的想法:

首先，我使用subprocess.Popen创建了一个进程

First of all, I created a process by using subprocess.Popen

第二，经过一定时间后，我尝试通过Popen.kill()杀死它

Second, after certain amount of time, I tried to kill it by Popen.kill()

import subprocess
import os, signal
import time

proc1 = subprocess.Popen("kvm -hda /path/xp.img", shell = True)
time.sleep(2.0)
print 'proc1 = ', proc1.pid
subprocess.Popen.kill(proc1)

但是，"proc1"在Popen.kill()之后仍然存在. 有专家可以告诉我如何解决这个问题吗? 感谢您的考虑.

However, "proc1" still exists after Popen.kill(). Could any experts tell me how to solve this issue? I appreciate your considerations.

感谢所有专家的意见，我做了您所建议的一切，但结果仍然保持不变.

Thanks to the comments from all experts, I did all you recommended, but result still remains the same.

proc1.kill() #it sill cannot kill the proc1

os.kill(proc1.pid, signal.SIGKILL) # either cannot kill the proc1

谢谢你们.

我仍在等待您解决这一微妙问题的宝贵经验.

And I am still waiting for your precious experience on solving this delicate issue.

推荐答案

在您的代码中应该是

proc1.kill()

kill或terminate都是Popen对象的方法，该对象将信号signal.SIGKILL发送到进程.

Both kill or terminate are methods of the Popen object which sends the signal signal.SIGKILL to the process.
