[ckan-dev] Issues with Deploying Source Install on Vagrant VM

I've been following the Installing CKAN from
Source<http://docs.ckan.org/en/latest/maintaining/installing/install-from-source.html>
and
the Deploying a Source
Install<http://docs.ckan.org/en/latest/maintaining/installing/deployment.html>
guides
to construct an Ansible playbook to provision a Vagrant virtual machine.
Ideally once I have nailed down this process I will add the production
server to the Ansible hosts file. Everything seems to work fine except for
the actual site being served by Apache via WSGI.

A few general notes:
[1] I can SSH into the VM and run 'paster serve' to serve the site on port
5000. I can also accomplish this via a task in my Ansible playbook with the
same results. Visiting my domain on this port is successful; I can see the
CKAN site, e.g. http://opendata.chattlibrary.dev:5000

[2] I have checked that Apache Solr is correctly configured and running.
Visiting http://opendata.chattlibrary.dev:8983/solr lands me on the Solr
page.

[3] When I visit the root domain, i.e. http://opendata.chattlibrary.dev, I
am directed to the Apache default site page OR the Nginx default site page.
Upon disabling the default Apache site and reloading Apache + Nginx, I
visit the root domain and am presented with a HTTP 404 response stating
"The requested URL / was not found on this server".

>From my understanding, the Apache config file is redirecting HTTP requests
to my WSGI application (CKAN). It would appear that CKAN is not actually
running. I understand this problem has more to do with Apache + Nginx +
WSGI and less to do with Vagrant + Ansible, but I'm including the relevant
portions in this email. I was under the impression that serving the site
with paster is not best practice, so there is something here I'm missing.
Any help would be greatly appreciated!

[site.yml] This is my main playbook. It's ugly, but it gets the job done
for the moment.
