[GeoNode-users] geonode causing alphabetic dependency in apache sites-enabled

[Charles Cossé]

When serving 2+ apache-wsgi-django sites from the same server each site's
wsgi.py contains a section like:

settings_module = "mysite.settings"
os.environ.setdefault("DJANGO_SETTINGS_MODULE", settings_module)
import django
django.setup()

After a couple requests to different virtual domains (using different
settings.py) site#2 can easily find itself trying to use site#1's
settings.py and producing errors.  Unless(!) you add the following in the
associated /etc/apache2/sites-available/mysite.conf files:

    WSGIDaemonProcess www.mysite.org processes=1 threads=20
inactivity-timeout=60 display-name=[wsgi-mysite]httpd
    WSGIProcessGroup www.mysite.org
    WSGIScriptAlias / /var/www/mysite/mysite/apache/wsgi.py

This keeps the respective wsgi processes separated and eliminates the above
confusion.  I've struggled with this for some time and only just found this
solution, so sharing for anyone with similar problems.  Have not tested
with respect to the "alphabetic dependency" mentioned in original message,
but this certainly applies when serving additional virtual domains
alongside geonode.
