Do you know any guide on this forum that teach how to run a ragnarok server on a dedicated server or vps?

VPS behaves just like a real machine in term of running programs. So there's no difference between the two on running rAthena
Thanks , and another question,imagine that i buy a dedicated server, to configure for run my server i need to configure on CentOS? all dedicated servers are on centOS? sorry i dont know nothing about this, I've never buy a dedicated server or a vps
No you can select the one you know distribution on linux Like centos is the most easiest and always use for hosting server.
So if i choose CentOS i need tu put codes all time on putty to configure my server? like "-cmd.....", imagine that i want to change a thing on the rates, i need to put codes etc to change the rates and access the file?
