Two projects fail to import the same main app when I turn on both in Apache

[Thomas Levine]

Hi,

For like the first time ever I want to make complicated websites,
so using Django finally seems like a good idea. And it is! All the
small building blocks that I had never thought of are already here.
Anyway, the part that's relevant to my present concern is that I
haven't deployed Django many times before and thus don't really know
what I'm doing.

I have two sites that I want to host on the same computer.
I have root access on this computer. The two sites are called
"dadaportal", which is on https://thomaslevine.com, and "scott",
which is on http://scott.dada.pink.

I also have a bunch of other sites configured in Apache, but
none of those uses wsgi or even Python.

Both sites work fine if I disable the other. Here is what its
configuration looks like.
http://big.dada.pink/010-dadaportal.conf
http://dada.pink/dadaportal/dadaportal/wsgi.py
http://dada.pink/dadaportal/dadaportal/settings.py

And here is the other.
http://big.dada.pink/015-scott.conf
http://dada.pink/scott2/scott2/wsgi.py
http://dada.pink/scott2/scott2/settings.py

I have problem when I try to run both at the same time.
The 010-dadaportal.conf and 015-scott.conf are in my
/etc/apache2/sites-available directory, so I have been
enabling them and disabling them like this.

a2dissite 010-dadaportal && a2ensite 015-scott &&
service apache2 reload && sleep 1s &&
a2dissite 015-scott && a2ensite 010-dadaportal &&
service apache2 reload

If I disable both of them and access either one in a web
browser, this shows up in the error log corresponding to
the If I try to access either one.

[Tue May 05 09:10:14.433772 2015] [wsgi:error] [pid 4155] [remote 79.136.47.106:512] ImportError: No module named 'dadaportal'

For example, here is a line from /var/log/apache2/scott2-error.log,

[Tue May 05 09:10:14.433772 2015] [wsgi:error] [pid 4155] [remote 79.136.47.106:512] ImportError: No module named 'dadaportal'

and here is one from /var/log/apache2/dadaportal-error.log.

[Tue May 05 09:13:01.552357 2015] [wsgi:error] [pid 4338] [remote 79.136.47.106:512] ImportError: No module named 'dadaportal'

Note that both projects look for "dadaportal". dadaportal is the
app containing the settings file in the dadaportal project.
http://dada.pink/dadaportal/manage.py

It is not in the scott2 project; I checked by running the following
command from the root of the scott2 project.

$ grep --include='*.py' -r dadaportal .

It printed nothing. Here are versions of things.

$ pip3 freeze|grep Django
Django==1.8.1
$ python3 --version
Python 3.4.2

Any idea of what I'm doing incorrectly? Thanks

Tom

You're missing the process-group argument from WSGIScriptAlias so it
tries to run both of them in the default process group.
