问题
getting confused here. I'm trying to install a second instance of reporting service sql server 2008 r2. Now does it mean I need to install a second instance of sql server or can i use the existing sql server instance to create anothe reportserver database?
回答1:
for 2005 I know that you would have to run setup again to install another instance. I am not sure if they changed it in later versions, although I believe it is still the same.
回答2:
See "Installing Multiple Instances of Reporting Services" and "Multiple Reporting Services instances on one machine". If you want to share one database, consider a scale-out deployment.

No, you don't have to install sql engine instance. You start an installation from SQL Installation Center and check only Reporting from features.
