If you’re thinking SEO – it’s myth. You do not need each one on a separate IP. Think of shared hosts. Unless you’re doing heavy interlinking (which is considered blackhat seo) then there really is no need at all.

I have wordpress MU (3.0) set up and configured on my server. I was wonder if there is anyway to map domains using multiple different IP adress. I have 10 IP address set up on my VPS. Is there anyway to use different IPs on new mapped domains?

Just wanted to chime in here. I have my network that I commented about above, running on a Hostgator server just fine. I have 10 domains. The main install, and 9 others all mapped to network sites.

For my above issue, trying to get the non-www addresses to work, I just wrote an .htaccess rule for each site pointing the non-www back to the www address. I figured this out with some help on the wp.org forums. You can see the thread here:

http://wordpress.org/support/topic/plugin-wordpress-mu-domain-mapping-non-www-mapped-domians-erroring-out

My only issue is that in the section of any of the subdomains, it references the main site. I don’t thinks that’s good for SEO purposes.

Andrea: Yes I did. Here’s a screen shot of the Super Admin panel (ok, can’t past it in – image uploaded here: http://www.becomebetter.com/domain-map.jpg). As you can see, according to the panel, the domain is mapped. However, when I try to actually load it, either directly in a browser or in the Super Admin panel by hitting the “Backend” or “Visit Site” links, I get the aforementioned 403 error.

From what I’ve researched on the Net, it might be a server side issue. Should I bother trying to mess with that or just go ahead and change hosts now? I’m planning to do that anyway. I’m considering a VPS account at HostGator – are they “WPMU-friendly?”

Thanks in advance for the advice.

My problem comes in trying to add domain mapping. I have a separate domain name (www.betternotolder.com) that I purchased from GoDaddy that I’d like to map to http://www.becomebetter.com/test/.

First, I’ve installed the Domain Mapping plugin and got it running with no problems.

Second, I’ve added an A record to the DNS record of http://www.betternotolder.com so that it points to the root directory of my multi-WP install.

I should be all set, right? However, when I load http://www.betternotolder.com into my browser, instead of loading the “Test Blog,” I get:

Forbidden

You don’t have permission to access / on this server.
Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.

Apache/1.3.33 Server at AppStuff Port 80

Anybody have any hints as to what I should try next? Any help, suggestions, or comments, would be greatly appreciated.

One thing that seems to come up a few times in this discussion, but never really explained by the ninjas, is getting a subdomain that it mapped to work if someone types subdomain.com into their address bar.

Just so I can let you know all my steps:

A. I have my main domain as the main account on a shared host (hostgator with cpanel)

B. I created a subdomain and called it * and the root domain = maindomain.com and the document root is /public_html

C. In my wp-config.php I have this rule define( ‘DOMAIN_CURRENT_SITE’, ‘maindomain.com’ );

D. In my domain mapping options, I have it set to to server CNAME domain instead of the IP address (the ip doesn’t go to my main site if I type it in my address bar) and I’ve entered maindomain.com

E. I’ve successfully parked 10 subdomains and added 10 subdomain.maindomain.com sites.

F. I’ve successfully mapped each subdomain to work at http://www.subdomain.com.

G. Here is where my trouble starts. If I navigate to subdomain.com or maindomain.com without the www I get an error “The page isn’t redirecting properly Firefox has detected that the server is redirecting the request for this address in a way that will never complete. * This problem can sometimes be caused by disabling or refusing to accept cookies.” – This seems like a big error to me. How can I force an attempt to navigate to a non www site go to the correct http://www.site.com address?

Any help would be greatly appreciated.
