On deploying 2013 on SQL Server 2012, you might get an error when running the configuration wizard to create the SharePoint farm:

“Configuration Failed.”

“Failed to create the configuration database”

“An exception was thrown: This SQL Server instance does not have the required “maxdegree of parallelism” setting of 1”

 

This can be resolved as follows:

  1. Open SQL Server Management Studio
  2. Right Click on your SQL instance and select Properties
  3. Select “Advanced” and change “Max Degree of Parallelism” from 0 to 1
