Setting up pico behind apache using mod_wsgi

StackOverflow https://stackoverflow.com/questions/21599270

Question

I'm trying to use pico for a small project. It works fine using the standard server shipped with pico but I'm unable to get it running on apache.

I've already gone through this guide and everything went smoothly so I know that mod_wsgi is configured correctly.

I followed the WSGI set up instructions on the pico wiki to the letter but this is the error I get when trying to access my page:

GET localhost/pico/client.js 404 (NOT FOUND)

Which results in the "pico is not defined" reference error.

All my test code is located in /var/www/ (I've tried other locations as well)

pico was installed using pip and is located in /usr/local/lib/python2.7/dist-packages/pico (I even tried modifying the access permission of the files in pico).

pico.wsgi is located in /var/www/pico/pico.wsgi

My pico.wsgi:

import pico.server
import sys
sys.stdout = sys.stderr # sys.stdout access restricted by mod_wsgi
path = '/var/www/' # the modules you want to be usable by Pico
if path not in sys.path:
    sys.path.insert(0, path)

# Set the WSGI application handler
application = pico.server.wsgi_app

I might not be using my "path" variable as intended but I don't see what else it should reference.

My httpd.conf:

WSGIScriptAlias /pico /var/www/pico/pico.wsgi

    <Directory /var/www/>
    Order allow,deny
    Allow from all
    </Directory>

My index.html (located in /var/www/):

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <link rel="stylesheet" type="text/css" href="style.css">
    <script src="http://d3js.org/d3.v3.js"></script>
    <script src="/pico/client.js"></script>
    <script src="picoTest.js"></script>
</head>
<body>
    <div id="container">
        <div id="toolbar"></div>
        <div id="graph"></div>
    </div>
</body>
</html>

And finally, sys.path printed from pico.wsgi:

['/var/www/', '/var/www/pico', '/usr/local/lib/python2.7/dist-packages/pip-1.3.1-py2.7.egg', '/usr/local/lib/python2.7/dist-packages/virtualenv-1.9.1-py2.7.egg', '/usr/local/lib/python2.7/dist-packages/distribute-0.6.35-py2.7.egg', '/usr/local/lib/python2.7/dist-packages/numpy-1.7.0-py2.7-linux-x86_64.egg', '/usr/local/lib/python2.7/dist-packages/gevent_websocket-0.3.6-py2.7.egg', '/usr/local/lib/python2.7/dist-packages/South-0.8.1-py2.7.egg', '/usr/local/lib/python2.7/dist-packages/daemon-1.0-py2.7.egg', '/home/kjartan/work/risk/maynard', '/var/www/pico', '/usr/lib/python2.7', '/usr/lib/python2.7/plat-linux2', '/usr/lib/python2.7/lib-tk', '/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload', '/usr/local/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages', '/usr/lib/python2.7/dist-packages/PIL', '/usr/lib/python2.7/dist-packages/gst-0.10', '/usr/lib/python2.7/dist-packages/gtk-2.0', '/usr/lib/pymodules/python2.7', '/usr/lib/python2.7/dist-packages/ubuntu-sso-client', '/usr/lib/python2.7/dist-packages/ubuntuone-client', '/usr/lib/python2.7/dist-packages/ubuntuone-control-panel', '/usr/lib/python2.7/dist-packages/ubuntuone-couch', '/usr/lib/python2.7/dist-packages/ubuntuone-installer', '/usr/lib/python2.7/dist-packages/ubuntuone-storage-protocol', '/usr/lib/python2.7/dist-packages/wx-2.8-gtk2-unicode']

I'm new to apache and wsgi in general so there might be something obvious I'm missing.

Was it helpful?

Solution

I think the WSGIScriptAlias line should be 

WSGIScriptAlias /pico /var/www/pico/pico.wsgi/pico

Note the /pico after the .wsgi

This became necessary after an update to pico a while ago but I forgot to update the wiki. Apologies for that.
