Killing a process created with Python's subprocess.Popen()
提问by user495511
Here is my thought:
这是我的想法：
First of all, I created a process by using subprocess.Popen
首先，我使用 subprocess.Popen 创建了一个流程
Second, after certain amount of time, I tried to kill it by Popen.kill()
其次，经过一定时间后，我尝试通过 Popen.kill() 杀死它
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)
However, "proc1" still exists after Popen.kill(). Could any experts tell me how to solve this issue? I appreciate your considerations.
但是，“proc1”在 Popen.kill() 之后仍然存在。有没有高手能告诉我如何解决这个问题？我很欣赏你的考虑。
Thanks to the comments from all experts, I did all you recommended, but result still remains the same.
感谢所有专家的意见，我做了你推荐的所有事情，但结果仍然一样。
proc1.kill() #it sill cannot kill the proc1
proc1.kill() #it sill cannot kill the proc1
os.kill(proc1.pid, signal.SIGKILL) # either cannot kill the proc1
Thank you all the same.
谢谢大家一样。
And I am still waiting for your precious experience on solving this delicate issue.
我仍在等待您解决这个棘手问题的宝贵经验。

How about using os.kill? See the docs here: http://docs.python.org/library/os.html#os.kill
使用 os.kill 怎么样？请参阅此处的文档：http: //docs.python.org/library/os.html#os.kill

In your code it should be
在你的代码中它应该是
proc1.kill()
Both killor terminateare methods of the Popenobject which sends the signal signal.SIGKILLto the process.
两者kill或terminate都是Popen向signal.SIGKILL进程发送信号的对象的方法。

Only use Popenkill method
只使用Popenkill方法
process = subprocess.Popen(
task.getExecutable(),
stdout=subprocess.PIPE,
stderr=subprocess.PIPE,
shell=True
)
process.kill()
