Server properties control the basic rules of your Minecraft server. You can change every one of them in the control panel, without editing any files.
Change a setting
- Open Properties in the menu on the left.
- Every setting is on this page. The quickest way to find one is the search box at the top.
- When you're done, click Save.
- Restart your server, so your new settings are loaded.
The settings people change most
- motd: the message players see under your server's name in their server list. See Server icon and MOTD.
- max-players: how many people can be online at the same time. See Change your max players.
- gamemode: the mode new players start in: survival, creative, adventure or spectator.
- difficulty: works just like in single player, from peaceful to hard.
- white-list: when it's on, only players you've added can join. It's a great way to keep your server private. You add players with
whitelist addin the console. See Turn on the whitelist. - allow-flight: if your server has mods or plugins that let players fly, turn this on so they don't get kicked for flying.
- view-distance: how far players can see, in chunks. A lower number uses less memory and can help with lag.
- level-seed: the seed for your world. It's only used when a brand new world is created. See Use a world seed on a Java server.
