I have been living and breathing SharePoint 2010 PowerShell the past two months.
During this time, I have created PowerShell scripts to prepare the farm, install SharePoint 2010, install and provision all service applications with their custom database names solely with PowerShell. This is on a multi-server SharePoint 2010 environment. So my scripts had to be able to create and join servers to the farm, start relevant services on App servers. No more stsadm for me!
The crawl server (index) was the most interesting as my script creates the Search SA and then modifies it with the specific database names that your variables you provide.
There were some (many) lessons learned and I will write more on that later.
I would like to show you how the SharePoint Products and Technologies Wizard works underneath and then marry those steps with equivalent PowerShell commands….
