Hi Daniel,
Which version of Apache are you running?
Did you enabled all the modules?
$ sudo a2enmod vhost_alias
$ sudo a2enmod proxy
$ sudo a2enmod proxy_http
$ sudo a2enmod proxy_wstunnel
$ sudo a2enmod rewrite
For the launcher configuration, do you have a proper
"resources" and "apps" section?
I'm guessing you are looking at the following
documentation pages?
-
https://kitware.github.io/paraviewweb/docs/guides/apache_front_end.html
<https://kitware.github.io/paraviewweb/docs/guides/apache_front_end.html>
-
https://kitware.github.io/paraviewweb/docs/guides/python_launcher.html
<https://kitware.github.io/paraviewweb/docs/guides/python_launcher.html>
Once you have the forwarding of the launcher request
working, the next part will be the forwarding of the
ws. But we can talk about it when and if you run into
issue about it.

Hi Daniel,
I want to use paraview web with SSL. As far
as I understand I need apache as a proxy
server for that? Or is it possible with
pvpython?
It might be possible with pvpython, but I've
never done it, I've always used apache to rely on
a single opened port and handle the encryption.
I have my own launcher which opens pvpython
with a different port for each user. Is this
the right way? Will this work with ssl?
If pvpython directly support the wss connection,
you can be good. Usually the setup, that I do is
that I have Apache serving only the port 443
(https) for both the static content and the (wss)
websocket endpoint. And I use a mapping file
between the Websocket endpoint that get returned
by my launcher and the host/port I should connect
to on the backend to establish the link between
the client and the actual ParaViewWeb server
instance.
But that does not mean, that's the only way to do
it and if you don't mind having several port
open, I don't see why it could not work.
Concerning:
https://kitware.github.io/visualizer/docs/
<https://kitware.github.io/visualizer/docs/>
The web visuailzer should work via npm
installation? It does not work for me:
C:\Users\danie\AppData\Roaming\npm\node_modules\pvw-visualizer\bin\pvw-visualizer-cli.js:41
var pvPythonExecs =
find(paraview).filter(function(file) { return
file.match(/pvpython$/) ||
file.match(/pvpython.exe$/); });
^ TypeError:
find(...).filter is not a function at
Object.<anonymous>
(C:\Users\danie\AppData\Roaming\npm\node_modules\pvw-visualizer\bin\pvw-visualizer-cli.js:41:36)
at Module._compile (module.js:409:26)
at Object.Module._extensions..js
(module.js:416:10) at Module.load
(module.js:343:32) at
Function.Module._load (module.js:300:12)
at Function.Module.runMain (module.js:441:10)
at startup (node.js:139:18) at
node.js:968:3
Well, I guess I haven't tried to run the new
Visualizer server on a Windows machine.
But with ParaView 5.2 (yet to be released), we
should have a ParaViewWeb back in the binaries.
So we should make sure our Visualizer command
line tool work on that platform as well.
Although, the command line is more for beginners
than anything else as it only simplify the demo
usage. In real word deployment, with a launcher,
the true pvpython command line should be used
instead.
Here is an example of what you should see in a
working environment:
$ Visualizer -d ~/Downloads/
===============================================================================
| Execute:
| $ /Applications/paraview.app/Contents/bin/pvpython
| -dr
|
/Users/seb/Documents/code/Web2/visualizer/server/pvw-visualizer.py
| --content
| /Users/seb/Documents/code/Web2/visualizer/dist
| --port
| 8080
| --data
| /Users/seb/Downloads/
