I have a Linode instance of Ubuntu 10.4 using the LAMP stack to host an instance of Magento and a couple other things. I currently have Magento set up at: http://123.459.780.123/magento.
When I apply my domain using the Linode tools, I can apply it so that I can access the Magento site at: http://example.com/magento.
I would like to host multiple sites, so that I can have /magento, /mysite, and /aclientsite all hosted under Apache, but have domains resolve to those paths, so that the root of the individual sites are those, so I can have http://exampleA.com, http://exampleB.com and http://exampleC.com.
I've done this before using tools in GoDaddy, but never using just Ubuntu and SSH access. Can someone explain what I need to do to point domains to folders in Apache?
