Central Administration in SharePoint Server 2016 is where you go to perform administration tasks from a central location. SharePoint 2016 brings another improvement in this category as well. Now Central admin will not be provisioned on all servers in a farm by default. CA will install on the first server in the farm on which you run the SharePoint Products Configuration Wizard. 

Moreover, Central Administration site is not deepened on the MinRole. Now you can provision Central admin on any server irrespective of their role in the farm (MinRole). MinRole Health will not try to provision or un-provision it.

There are four different ways to provision / unprovision Central admin in a Local server:
  • Services on Server page on Central Administration > System Settings
  • Windows PowerShell cmdlets (new-spcentraladmininstration)
  • The psconfig.exe -cmd adminvs operation
  • The SharePoint Products Configuration Wizard
