Configuring DNS

Starting a brand new website and running into issues with setting up Multisite. i want to use subdomains (like username.my-domain.net ).

I have WordPress set up for that by the instructions here.

(Thanks, Ipstenu!)

Now I’m trying to configure the DNS side of things.

I set up a ‘A’ record in my DNS on Godaddy.

Host | Points To
—————————
* | IP Address of Server

Then my Apache 000-default file:

<VirtualHost *:80>
DocumentRoot /var/www/websites/My Directory.net
ServerName http://www.my-domain.net
ServerAlias *.my-domain.net
</VirtualHost>

All well and good. I log in with no problem, although my browser points to my-domain.net instead of http://www.my-domain.net.

When I try to go in to the Super-Admin dashboard, it logs me out and won’t let me log in. It tries to route me, I’ve noticed, to http://www.my-domain.net/wp-admin/network, but I can’t get to http://www.my-domain.net no matter what I try. It keeps taking me to my-domain.net without the “www”. Seems to me that it’s an Apache configuration issue.

I get a lot of lines similar to this in the error.log:

File does not exist:/var/www/websites/my-domain.net/users

There shouldn’t even be a file called that, right?

I’m a bit confused here and would appreciate some help.

Thanks, all!
