Changing the Central Administration TCP port
During installation the SharePoint Central Administration site is assigned a randomly generated TCP port. I have decided to change mine to something memorable as I can never remember it and have to log on to the server to check.
The best way to change the port is via the PowerShell using the following command:
Set-SPCentralAdministration -Port <PortNumber>
Note: You cannot assign a port lower than 1023, higher than 32767, 0r 443
