Apache Virtual Hosts for Django

Question

Hi,

I have a django project up and running on Webfaction, but would now like to have it support multiple virtual hosts. All instances will use the same django project, just a different settings file and separate DB. I've been reading about setting up VirtualHosts in Apache, but I'm a little lost because the default httpd.conf doesn't already have a virtual host entry so I'm not sure what should go in that section versus what remains outside of it. Also, it seems there are different ways to set it up to be more efficient. Is there any documentation on how to go from a default httpd.conf to one with Virtual Host Entries?

Thanks

The VirtualHost entries should look like this:

NameVirtualHost *:YOUR_PORT

# Virtual Hosts

<VirtualHost *:YOUR_PORT>
    ServerName www.YOUR_DOMAIN.com
    ServerAlias YOUR_DOMAIN.com
    KeepAlive Off
    # The first "YOUR_DOMAIN.com" is just a process group.  The name is arbitrary.
    # The "display-name" shows up when running "ps -u YOUR_USERNAME -o pid,rss,command" to list processes.  Otherwise you can't tell which process belongs to which django app.
    WSGIDaemonProcess YOUR_DOMAIN.com processes=1 threads=20 inactivity-timeout=60 display-name=[wsgi-YOUR_APP_NAME]httpd
    WSGIProcessGroup YOUR_DOMAIN.com
    WSGIScriptAlias / /home/YOUR_USERNAME/webapps/django/wsgi/YOUR_APP_NAME.wsgi
</VirtualHost>

OK, that was one of the references I was using, but wasn't sure how to implement it. My httpd.conf (in part) went from this:

WSGIDaemonProcess django processes=2 threads=12 python-path=/home/roam3/webapps/django:/home/roam3/webapps/django/lib/python2.7
WSGIProcessGroup django
WSGIScriptAlias / /home/roam3/webapps/django/django.wsgi
WSGIRestrictEmbedded On
WSGILazyInitialization On

To this:

#WSGIDaemonProcess django processes=2 threads=12 python-path=/home/roam3/webapps/django:/home/roam3/webapps/django/lib/python2.7
#WSGIProcessGroup django
#WSGIScriptAlias / /home/roam3/webapps/django/django.wsgi
WSGIRestrictEmbedded On
WSGILazyInitialization On

NameVirtualHost roam3.webfactional.com:23113

# Virtual Hosts

<VirtualHost roam3.webfactional.com:23113>
ServerAdmin greg@reservation-net.com
ServerName roam3.webfactional.com
KeepAlive Off
# The first "YOUR_DOMAIN.com" is just a process group.  The name is arbitrary.
# The "display-name" shows up when running "ps -u YOUR_USERNAME -o pid,rss,command" to list processes.  Otherwise you can't tell which process belongs to which django app.
WSGIDaemonProcess django1 processes=2 threads=12 python-path=/home/roam3/webapps/django:/home/roam3/webapps/django/lib/python2.7 inactivity-timeout=60 display-name=[wsgi-roam3_roam3]httpd
WSGIProcessGroup django
WSGIScriptAlias / /home/roam3/webapps/django/django.wsgi
</VirtualHost>

But I get a 404 error now. I've mucked about, but I don't know enough to know what's wrong.

I just fixed the formatting on your comment (you need to indent code blocks).

The NameVirtualHost and VirtualHost bits needs to include asterisks as I showed in my example, "*: 23113" and not "username.webfactional.com:23113".

Can you fix that, restart your Apache, and try again?

Also, this is a public forum, so you might want to leave sensitive details like your username and hostname out of your comments :)

Replacing the url with * generates a 500 Internal Server Error message. I had tried that originally. I also figured that couldn't be the answer as how would I setup multiple domains? A * on NameVirtualHost and url in VirtualHost block gives me a warning when restarting Apache, and a 404. So I think the error is in the VirtualHost block.

The answer is that the setup I had was mostly correct. It does need *:port everywhere, but the problem was that the first value in WSGIDaemonProcess and the WSGIProcessGroup have to have the same value. However, if there are multiple <virtualhost> blocks the same Process name can't be used in each block.

That's the reason that the example I provided used "YOUR_DOMAIN.com" in the WSGIProcessGroup and WSGIDaemonProcess directives - to ensure that it would match within each virtual host, and that it would be unique to each virtual host.
