python - 停止 ipcluster 引擎(IPython Parallel)

Question

如何停止已启动的引擎:
ipcluster 引擎 --n=8 --daemonize


当前运行的进程如下所示:

/usr/bin/python /usr/local/bin/ipcluster engines --n=8 --daemonize
/usr/bin/python -m IPython.parallel.engine --profile-dir /home/ubuntu/.ipython/profile_default --cluster-id  --log-to-file --log-level=20

我不想运行killall python。

从客户端，您可以调用shutdown:

import IPython.parallel as ipp
rc = ipp.Client()
# shutdown specific engines
rc.shutdown([1, 5])
# shutdown all engines:
rc.shutdown()
# shutdown everything, including the Hub
rc.shutdown(hub=True)
