Apache WSGI Konfiguration:

<VirtualHost _default_:443> 
    ... 
    # Default other config goes here... 
    WSGIScriptAlias//home/trex/workspace/scripts/appwsgi.py 
    WSGIScriptReloading On 
    <Directory "/home/trex/workspace/scripts"> 
    <Files "appwsgi.py">

    </Files> 
    </Directory> 
</VirtualHost> 

Lassen Sie mich wissen, wenn noch etwas anderes kann ich Ihnen die Details geben.

Answer 1

Es gab ein Problem mit Berechtigungen für meine virtualenv. Die folgende Datei hatte Berechtigungsprobleme.

myenv/lib/python2.7/site-packages/httplib2-0.9.2-py2.7.egg/httplib2/cacerts.txt 

Und diese einfache Lösung fixiert mein Problem:

chmod -R 755 /home/trex/workspace/myenv
