I am new to linux and have been using CentOS 6 as a Minecraft server for about 2 months now. I rarely use the GUI and mostly use SSH to the server. I want to place my Minecraft worlds in a ramdisk but have not had much luck understanding how to do this. I have found bloated shell scripts that are not commented so I cannot break it down to understand. I would love a basic, beginners guide to help me out.
All I want to do is assign a specific size to the ramdisk and load each world folder into its own ramdisk (maybe a single ramdisk if that's how it is supposed to be done), then start the server. I know data in a ram disk is volatile and would need to be backed up regularly. I have a backup plugin to do this. I appreciate any help you can offer. Thank you.
