I’ve recently noticed some posts on the BuddyPress forums where people are having problems getting WordPress MU and BuddyPress running locally on their machine.
I spent some time today to put together a twenty minute video that will show you how to set up and run WordPress MU and BuddyPress locally on a Mac. There is a tool you can use that will make this very easy called MAMP. For those of you running Windows, there is a similar tool called WAMP that will basically do the same thing.
I also make use of Textmate in this screen cast to edit the hosts file, if you don’t use it you can simply open the Finder, use the “Go” menu, and then the “Go to folder” option. Enter /etc/ as the folder and then scroll to the “hosts” file and use the editor of your choice. If you are familiar with the terminal you can also use your command line editor of choice.
I highly recommend you turn on the HD option for this video and make it full screen, that way you’ll easily be able to read and follow along.
