I recently read this walkthrough of how to use multisite and I'm almost there, but stuck on how to get my subdomains to work: http://weblogtoolscollection.com/archives/2010/06/02/wordpress-3-multisite/
Just changed servers and my configuration of WP from multiple installs using one database to a one install-network-on-one-database. My blogs consist of one domain and four subdomains of that main one. I feel that I am missing something key to get the installation to work properly. I can see the main blog, but cannot access my four subdomains. I will not be allowing others to register new subdomains under my WP network so, correct me if I’m wrong, I don’t need access to wildcard subdomains. Within WP I’ve created the info to make the four subdomain sites. In CPanel I’ve created the subdomains I need, but I did notice that they are pointing to subfolders outside the WP install (I perceive that herein lies part of the problem). If I need a static IP, that may be an issue. I want my sites to garner their own pagerank not to be viewed as mere extensions of the main domain (why I am not using subdirectories).
One thing mentioned in the tutorial is: “If your host supports it, you’ll have the option here to choose between subdomains and subdirectories.” How do I know if my host supports it? What do I need to look for or ask? Would it be better to switch to subdirectory installation and use the domain mapping? Or does that require a static IP? If I do this should I erase the subdomain records in my CPanel and change the CNAME/ANAME records with my domain provider? As you can tell I’m kinda stuck and very confused. I feel like I am missing the keystone to my bridge – both sides are done but the part that ties them together is gone. It may just be a lack of understanding on my part how they are supposed to communicate together, but I’m stuck nonetheless.
I would really appreciate anyone's help. I haven't been able to get my subdomains to work at all. I don't know if it's something I am not configuring correctly or if it's something that my webhost doesn't offer. Any guidance and explicit instructions on what to look for or ask would be very appreciated.
