I currently have a VPS to host a gaming website. But however, I don't know what OS to put. Here's the list it gave me. Note: I need a OS that's preferably for a gaming website. Also, I'm using xenForo too
@Yashjeet, you won't go wrong with either centOS or Debian (which is MY poison of choice). With either one you will get some good help here on the forums. I just got through setting up recently a VPS for another site owner on Debian but I mess very little with centOS currently (mainly because I'm not comfortable enough with it to do it for someone else).
The main thing I WILL tell you - whichever one you choose, be sure that you secure it well and that you keep it updated regularly. To often those that get a VPS get it set up and then don't worry about it to much. There ARE regular updates that come out that do need to be applied.
Disable ROOT logon in SSH and then install sudo (if it isn't already installed) and configure it. Then you are able to assume the root user completely if needed or just run a command with root priv's (which is normally what you need).
