Apache subdomain for graphite using mod_wsgi and SSL - ssl

Question

I am having trouble configuring my apache with a new subdomain.
Its a ubuntu server with apache2 and graphite, I have graphite working on port 80 (installed via apt-get)
Now the apache server currently serves a website (https://subdomain1.domain.com) and I would like to set up apache to serve the graphite app on https://subdomain2.domain.com (port 443). This is so subdomain1 can access the charts from graphite.
This is my apache2-graphite.conf
<VirtualHost *:80>
WSGIDaemonProcess _graphite processes=5 threads=5 display-name='%{GROUP}' inactivity-timeout=120 user=_graphite group=_graphite
WSGIProcessGroup _graphite
WSGIImportScript /usr/share/graphite-web/graphite.wsgi process-group=_graphite application-group=%{GLOBAL}
WSGIScriptAlias / /usr/share/graphite-web/graphite.wsgi
Alias /content/ /usr/share/graphite-web/static/
<Location "/content/">
SetHandler None
</Location>
ErrorLog ${APACHE_LOG_DIR}/graphite-web_error.log
# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.
LogLevel warn
CustomLog ${APACHE_LOG_DIR}/graphite-web_access.log combined
</VirtualHost>
and the /usr/share/graphite-web/graphite.wsgi :
import os, sys
os.environ['DJANGO_SETTINGS_MODULE'] = 'graphite.settings'
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()
from graphite.logger import log
log.info("graphite.wsgi - pid %d - reloading search index" % os.getpid())
import graphite.metrics.search
I have tried changing the port and setting a ServerName and ServerAlias, and enabling SSL, but I havent been able to get this working.
Sample (not working):
<IfModule mod_ssl.c>
<VirtualHost *:443>
ServerName graphite.<my_domain_here>
WSGIDaemonProcess _graphite processes=5 threads=5 display-name='%{GROUP}' inactivity-timeout=120 user=_graphite group=_graphite
WSGIProcessGroup _graphite
WSGIImportScript /usr/share/graphite-web/graphite.wsgi process-group=_graphite application-group=%{GLOBAL}
WSGIScriptAlias / /usr/share/graphite-web/graphite.wsgi
Alias /content/ /usr/share/graphite-web/static/
<Location "/content/">
SetHandler None
</Location>
ErrorLog ${APACHE_LOG_DIR}/graphite-web_error.log
# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.
LogLevel warn
CustomLog ${APACHE_LOG_DIR}/graphite-web_access.log combined
SSLEngine on
SSLCertificateFile /etc/apache2/ssl/public.crt
SSLCertificateKeyFile /etc/apache2/ssl/private.key
SSLCACertificateFile /etc/apache2/ssl/ca.crt
</VirtualHost>

Answer 1

I found what I was doing incorrectly:
I added the subdomain to my /etc/hosts on my workstation and It worked!
Registered the subdomain with our web host and all OK now
Ill leave this here in case it helps someone else...
