How To make 2 Private servers

I want to know how to make 2 Private Server on the same Dedicated
If Any one can help to Change Ports and give me Msg and Npc Server and Sell with New Ports i will be pleased . i waiting . i really need it fast [ for 5065 ]

Okay so im not flaming or anything like that... but you need to run 2 servers on one dedi and dont know how to change ports? and Msg and NPC server???? Seriously how do you expect to run 2 servers/worlds/realms or w/e from 1 IP if you don't know how to do much?

Why not just try running one successful server first?

if (WantingPortChange == true)
{
TypeInSearchBox("PortNumber");
Search.Press();
}

tbh I dont know how you would go about searching for something like a port number... and changing it MUST be really hard... Hah sorry for the sarcasm lmao
