flask bokeh bokeh服务器-图不渲染（ubuntu），但在本地计算机上工作

Question

I've created a bokeh plot that is accessible through Flask. I am able to successfully run bokeh server through flask on my local machine via

bokeh server bokeh serve--allow-websocket-origin=localhost:5000 filename.py

flask python run.py on two command windows

Now I want to do the same thing but on a virtual machine running ubuntu. Using the exact same commands on two putty windows no longer work. I am able to access non-bokeh html pages though.

When trying to access the bokeh plot, I get:

OSError: Cannot pull session document because we failed to connect to the server (to start the server, try the 'bokeh serve' command)

but I already intitiated bokeh serve

this is the code snippet in flask that will call bokeh server

@main.route("/grid")
def bokehserver():
    session=pull_session(url="http://localhost:5006/filename")
    bokeh_script=autoload_server(None, url="http://localhost:5006/filename",session_id=session.id)
    return render_template("bokserv.html",bokeh_script=bokeh_script)

edit: I'm reading something about 'linux server configuration files' for running bokeh server on linux. I have not made such configuration files. Can someone confirm whether these are totally necessary? I don't want to overstuff my project with excess. In many examples I've seen, the developer uses nginx and gunicorn and other things to get flask/bokeh up and running, but so far I've been able to avoid these extra layers..

edit2: bokeh serve --show filename.py in the ubuntu terminal generates the standard messages as if it is working but it doesn't open the browser to display the figure.

Answer 1

I created the configuration files referenced in the initial post and used bokeh serve --allow-websocket-origin=(my ip):5000 filename.py .

Then in the flask file from werkzeug.contrib.fixers import ProxyFix

then outside of the app.route(/) i put app.wsgi_app=ProxyFix(app.wsgi_app)

then I navigated to (my ip):5000

and it worked.
