How can I configure my server.properties file?

server.properties is a file in the main folder of your server which stores many of its important configuration options. Changing a setting should be as simple as opening the file in your server's Files tab, finding the line with the setting name on it, then editing the text after the = sign (sometimes there won't be anything after the = because it hasn't been set yet).

We've listed below some of the options in your server.properties that you might want to change, along with an example of what you might like to set it to.

level-seed

level-seed=-1696067516

A "seed" is a unique string of text which Minecraft uses when generating a world. This means if you find a world with terrain you like while playing singleplayer Minecraft, you can run the /seed command and copy the text to your clipboard, then paste it into your server.properties

gamemode

gamemode=adventure

The default gamemode is set to survival when creating your server, but you're welcome to set this to another one like creative, adventure or spectator. Setting players to Adventure Mode might be useful if you're making an adventure map, and don't want players destroying the world!

If you want players to be forced into this gamemode whenever they join the server (overriding if they were manually set to creative before, for example), set force-gamemode to true

enable-command-block

enable-command-block=true

If you'd like command blocks to be usable in the world (although you'll still need to be an operator to give them to yourself), remember to set this to true otherwise they won't work.

enforce-secure-profile

enforce-secure-profile=true

Minecraft 1.19.1 introduced a chat reporting system, which also came with something called "chat signing" which ensures messages sent by players are legitimate, and were actually sent by their account. Disabling this means chat messages sent on your server cannot be reported, however this can sometimes solve issues where players with certain mods on their client are not able to join your server.

level-name

level-name=dropper-map-1

This is set to world by default, the name of the world folder on the server. If you have multiple worlds and want to switch between them easily, you can have multiple world folders with different names in the main folder of your server, then set this setting to the name of the world which you want to load on the next server start.

motd

motd=JOSH'S COOL SERVER!\ncool people only

The "MOTD" (Message Of The Day) is the two lines of text displayed below the server name in the server list:

The easiest way to create a fancy MOTD is using this website, where you can then copy and paste your generated MOTD into your server.properties – it can be customised using colour codes, icons, and even gradients if you use a tool like this. Use \n if you want to go onto the second line.

pvp

pvp=false

Players killing each other when you told them not to? PvP is on by default, but you can set it to false!

difficulty

difficulty=hard

Similar to the command, this allows you to set your server's "difficulty", with the available ones being:

• peaceful – hostile mobs don't spawn, hunger is always full meaning health regenerates quickly
• easy – mobs don't deal much damage, zombies can't break doors, cave spiders don't poison players
• normal – mobs deal more damage, hunger can decrease a lot, vindicators can break doors
• hard – mobs deal the most damage, hunger can kill players, zombies can break wooden doors

max-players

max-players=100

The maximum number of players who can play on your server at the same time. We don't limit your server's actual player slots, so you're free to up this number to whatever you wish (we set the default to 100), although keep in mind you're going to have to optimise your server heavily to handle large numbers like 100+.

online-mode

online-mode=true

Setting this to false can allow "cracked" players running illegal/illegitimate versions of Minecraft to join your server, but this can pose a security risk as it means anyone can join with the username of another player. We highly recommend keeping this set to true and will not provide support for cracked servers as they violate Mojang's EULA.

If you're running your server behind a Velocity/BungeeCord proxy, you will most likely have to set your server to offline mode, so ensure adequate protection (a forwarding secret ideally) is set up so players can't join directly. Please get in touch with us if this if you're setting up a network so we can also firewall your backend servers accordingly.

resource-pack

resource-pack=https://download.mc-packs.net/pack/ae1f474756c0011f0837188b6be478da5764d495.zip

Sets a resource pack for players to automatically download when connecting to the server. Learn more about how to set one up here.

allow-nether

allow-nether=true

If you don't want players entering the Nether just yet, set this to false to prevent players from entering it. I'm not sure what happens if you do this while players are in the Nether, but I wouldn't recommend finding out.

view-distance

view-distance=8

This controls the maximum "render distance" a user can have. Even if a user has the render distance on their client set to 16, it won't display chunks beyond the number which you set here. Sometimes decreasing this number can help with lag issues caused by lots of players exploring new chunks at once (something that can be avoided by pregenerating your world).

simulation-distance

simulation-distance=4

This sets the maximum "simulation distance" which is the number of chunks in each direction of the player in which entities are loaded. Again, this limit is set on the server so clients' render distances above this number won't have any effect. Lowering this may help with entity lag issues, but will mean players will have to be close to any mob farms they've built otherwise they won't activate/trigger mob spawns.

white-list

whitelist=true

We enable the whitelist by default and recommend you keep it enabled for private servers with friends. This avoids unwanted players from joining and griefing your server, which can happen even if you don't share your server's IP outside of your friend group!

level-type

level-type=minecraft\:normal

You can set your Minecraft server's world to a variety of "level types" which include:

• flat – a superflat world with no terrain, just grass
• large_biomes – a default world but with much larger biomes than usual
• amplified – a default world but the world gen height limit is increased, making for some pretty cool mountains

spawn-protection

spawn-protection=0

This is the number of blocks around your spawn point which will be protected from griefing by non-operators. If you want to work with your players to build a server spawn, it might be best to set this to 0 so spawn protection is disabled.

hardcore

hardcore=true

If set to true, the server is set to "Hard" difficulty and players will be set to Spectator Mode when they die. For professional Minecraft players only!

allow-flight

allow-flight=true

Contrary to what the name suggests, keeping this enabled won't allow players to fly around as if they're in Creative Mode, even if they are just in Survival. We have it enabled by default because it can prevent players from being kicked for "flying" while in minecarts/boats/other entities.
