I understand the "brain-dead easy" way to turn on Apache in OS-X, but how do I use my own domain (http://chanoc.com) and not whatever IP address the cable company gives me with dynamic addressing, looking like this: http://1010.01.010gci.net/~chanoccomputer. I would rather use my Mac to host my site, with access to over 120GB of content.
So is this easy, or should I be prepared to go to BASH and learn something new?
Actually, this is nothing to do with your system setup at all - it's something that you would set up with your domain registrar. See if they offer something called "URL forwarding" (some offer it free, some charge). If your IP is static, it's a simple matter of forwarding chanoc.com to your IP.
You can also get a "masked" forward, where your visitors are totally unaware that they've just been redirected (which is useful, since their browsers always display your domain name, rather than the less useful IP address).
