如何停止bokeh服务器? [英] How to stop bokeh server?

问题描述

我确实使用bokeh来实时绘制本地LAN上的传感器数据.Bokeh是从我的python应用程序中使用popen启动的: Popen("bokeh serve --host = localhost:5006 --host = 192.168.8.100:5006"，shell = True)

I do use bokeh to plot sensor data live on the local LAN. Bokeh is started from within my python application using popen: Popen("bokeh serve --host=localhost:5006 --host=192.168.8.100:5006", shell=True)

我想从应用程序中关闭bokeh服务器.但是，我在文档中找不到任何内容.同样， bokeh服务--help 也没有给出任何提示.

I would like to close bokeh server from within the application. However, I cannot find anything in the documentation. Also bokeh serve --help does not give any hint how to do that.

基于公认的答案，我想出了以下解决方案:

based on the accepted answer I came up with following solution:

        self.bokeh_serve = subprocess.Popen(shlex.split(command),
                             shell=False, stdout=subprocess.PIPE)

我使用 self.bokeh_serve.kill()结束了该过程.也许 .terminate()会更好.我会尝试的.

I used self.bokeh_serve.kill() for ending the process. Maybe .terminate() would be better. I will try it.

推荐答案

在不了解bokeh且假设您使用Python> = 3.2或Linux的情况下，您可以尝试使用 SIGTERM ， SIGINT 或 SIGHUP ，使用 os.kill() 与

Without knowing bokeh and assuming that you use Python >= 3.2 or Linux, you could try to kill the process with SIGTERM, SIGINT or SIGHUP, using os.kill() with Popen.pid or even better Popen.send_signal(). If bokeh has proper signal handlers, it will even shutdown cleanly.

但是，最好使用选项 shell = False ，因为使用 shell = True 时，信号会发送到Shell，而不是实际的进程.

However, you may be better off using the option shell=False, because with shell=True, the signal is sent to the shell instead of the actual process.
