[I want to create a private server and then make it public]

Hi, I haven't played ragnarok for a long time, but I want to create a private server and then make it public and between people. 
The question is: what do I need to open a private server on my own PC and be able to modify it? I need to know what I should download (even that ragnarok download) please I need help.
 Now I study programming and understand code but I don't remember what to download.
