Configuring SharePoint with PowerShell is quite easy, rather than running the Configuration Wizard post-installation. The primary advantage is to give you control over the Administration database. This method works with SharePoint 2010 and SharePoint 2013.
After installing SharePoint, run the SharePoint Management Shell as Administrator.
New-SPConfigurationDatabase -DatabaseName Config -DatabaseServer SPSQL -AdministrationContentDatabase Admin -FarmCredentials (Get-Credential) -Passphrase (ConvertTo-SecureString "Password1" -AsPlainText -Force)
New-SPCentralAdministration -Port 8080 -WindowsAuthProvider NTLM
TechNet also has this information, I just had to scroll too much. And now I have a source to directly copy and paste from :-)
