I have a site I need to create a subdomain for, managed by rackspace cloud.
The domain is already setup and online. I just need to copy the current www.mysite.com to lab.mysite.com.
How do I go about doing this?
Do I add the subdomain in the cloud sites listing, or under the listing for the domain?
And where do I copy the files to? The current site is at /www.mysite.com/web/content on the ftp.
Actually, there is much difference between Rackspace Cloud Sites and Rackspace Cloud Servers, and the ways to manage domains/subdomains are also different.
So, if you have a Cloud Sites account, that should be a part of the control panel.
But if you are on a Cloud Server, it's not the same thing :
Login to your NextGen admin panel choose your server, and open the DNS tab.
Here, you can add a record for your domain sub.domain.com to make it match your server's IP. Then you'll have to tell Apache there's a new domain to deal with (a virtual host).
As an example, if you are running an Ubuntu Server, that should work something like that.
PS: There's also an official article in the Rackspace Knowledge Center, but i'm not a fan of the proposed solution.
