This guide shows you how to install and configure SQL Server 2012. The configuration includes assigning permissions and configuring networking.
SQL Server 2008 installation
The installation of SQL Server 2008 compared to SQL Server 2008 R2 is almost the same and described below.
If you get a compatibility warning while trying to install SQL Server 2008 on Windows Server 2008 R2 you can proceed with install.
Before running SQL Server you need to apply Service Pack 1.
SQL Server 2008 R2 installation
If you haven’t done yet install .NET Framework 3.5 SP1.
On the left side click “Installation” and on the right side click "New installation or add features to an existing installation".
Install the setup support files.
Select “SQL Server Feature Installation”.
Select the “Database Engine Services” feature and the “Management Tools - Basic” feature. Check additional features if needed.
Check additional features if needed.
Keep the default instance and default folders.
Use the same account for the services and select the sqlSvcAcc you created in Active Directory.
Keep the collation settings you can see in the screenshot.
Add the SharePoint 2010 setup administrator user as a “SQL Server Administrator”.
Click next at the “Installation Configuration” Rules screen.
Start the installation of SQL Server 2008 R2.
SQL Server 2008 R2 configuration
There are 2 configuration steps you need to do: assign permission to the SharePoint 2010 setup administrator and configure networking.
The SharePoint 2010 setup administrator needs to have the securityadmin and dbcreator role. The sysadmin role is assigned if you decide during SQL Server 2008 installation that your SharePoint 2010 setup administrator should be the SQL admin.
I decided to do so in my Hyper-V development environment.
At the end you need to configure networking if you are planning to deploy a farm with multiple SharePoint Server 2010 servers.
According to TechNet  you need to “ensure that SQL Server 2005 or SQL Server 2008 is updated to the required level and configured as follows”:
- SQL Server 2005: Local and remote connections are enabled and are configured to use the TCP/IP protocol.
- SQL Server 2008: The TCP/IP protocol is enabled for the network configuration.
RTM: TechNet still says (May 6, 2010) you need TCP/IP but you don’t need Named Pipes. From my experience you need Named Pipes.
Difference to SharePoint 2007
In SharePoint 2007 you needed to configure named pipes which isn’t necessary in SharePoint 2010.
Step 8: SharePoint Server 2010 installation
