Server.properties



Server.properties is the file which stores all the settings for a multiplayer (Classic, Alpha or Beta) server.

If you are going to edit server.properties it is important that you use the same structure as the original uses. The text before the equal sign is the key, which you shouldn't change. The text after the equal sign is the key's value, which you can edit. Lines that begin with  are comments - altering or removing these has no effect on the game.

You need to restart your server if you change the settings file for the new changes to take effect.
