My friend and fellow WHS MVP Nigel Wilks has just released a guide to the Microsoft Web Platform Installer which will work on WHS 2011.
Here is how the guide starts:
Some time ago, I created a couple of Add-Ins for Windows Home Server V1 to make things easier for installing applications such as WordPress, PHP and MySql. Since the release of Windows Home Server 2011 I have had numerous requests to port them to the new platform which I was loath to do due to the age of the Add-Ins and the versions of the software I used.
Now that we have a good foundation Operating System in Windows 2008, the installation of web applications is easy enough that I won’t be fulfilling these requests. This is where the “Microsoft Web Platform Installer” comes in.
The installer will enable you to easily install a whole suite of applications from Sql through to WordPress, even Forum software such as PhpBB.
