Identity

MOTD motd

The message shown under your server in the multiplayer list. Supports color codes with § (section sign), e.g. §6Gold §lBold.

Ports managed by my panel (Pterodactyl / Solace)

Recommended. On Pterodactyl-based panels the server-port and query.port are written from your allocation on every boot, so any value you set here is overwritten. Leave this on and we'll omit those lines so they don't fight the panel.

Server port server-port

Default 25565. On shared/panel hosts this is assigned for you — don't change it unless told to.

Max players max-players

How many can join at once. More players = more RAM and CPU.

Server IP server-ip

Leave blank in almost all cases — the server binds to all interfaces. Only set this if you know you need a specific bind address.

Gameplay

Default gamemode gamemode

Difficulty difficulty

peaceful = no hostile mobs and natural health regen.

Force gamemode force-gamemode

Reset players to the default gamemode every time they join, even if you changed theirs.

Hardcore mode hardcore

Difficulty locked to hard; death is permanent (player switched to spectator). Overrides the difficulty setting.

Allow PvP pvp

Players can damage each other. Turn off for purely co-op/build servers.

Allow flight allow-flight

Stops the server kicking players for "flying" — needed for some mods/plugins (jetpacks, elytra hacks). Leave off on vanilla anti-cheat servers.

Allow Nether allow-nether

Enables Nether portals and the Nether dimension.

Enable command blocks enable-command-block

Required for redstone/command-block contraptions and many map mechanics.

Spawn monsters spawn-monsters

Hostile mobs spawn naturally. (Peaceful difficulty disables them regardless.)

World

World folder name level-name

The folder your world saves to. Change it to swap between multiple worlds.

World seed level-seed

Leave blank for a random world. Only applies when the world is first generated.

Level type level-type

amplified is very CPU-heavy. flat is great for creative/minigame servers.

Spawn protection spawn-protection

Radius (blocks) around spawn only ops can build in. 0 = off.

Max world size max-world-size

World border radius cap. Lower it to limit map size + disk use.

Performance

View distance view-distance

Chunks sent to players. The biggest performance lever. 6–8 for big/low-end servers, 10 is default.

Simulation distance simulation-distance

Chunks where mobs, crops, and redstone actually tick. Lowering this saves the most CPU.

Entity broadcast range entity-broadcast-range-percentage

How far away entities are sent to clients (percent). Lower (e.g. 75) reduces bandwidth/CPU on busy servers.

Network compression threshold network-compression-threshold

Packets above this byte size get compressed. -1 disables it (good for LAN); default 256.

Sync chunk writes sync-chunk-writes

Safer saves, but can cause lag spikes on some disks. Turning off can help on slower storage — at slightly higher corruption risk.

Players & Access

Online mode online-mode

Keep this ON. Verifies players against Mojang/Microsoft auth. Turning it off allows cracked clients and is a major security risk (unless you're behind a proxy like Velocity/BungeeCord that handles auth).

Whitelist white-list

Only players on the whitelist can join. Manage names with /whitelist add <name>.

Enforce whitelist enforce-whitelist

Immediately kicks online players who get removed from the whitelist (not just at next join).

Player idle timeout (min) player-idle-timeout

Auto-kick AFK players after N minutes. 0 = never. Useful on full, popular servers.

Op permission level op-permission-level

Function perm level function-permission-level

Permission level datapack functions run at.

RCON & Query (advanced)

Enable RCON enable-rcon

Remote console access (for panels, Discord bots, restart scripts). Always set a strong password if enabled.

RCON port rcon.port

RCON password rcon.password

Required if RCON is on. Never reuse your account password.

Enable query enable-query

Lets server-list sites and tools read live stats (player count, MOTD). Safe to enable.

Query port query.port

Resource Pack (optional)

Resource pack URL resource-pack

A direct download link to a .zip. Leave blank for none.

Require resource pack require-resource-pack

Players who decline the pack get kicked. Only meaningful when a pack URL is set.

Upload this as server.properties in your server's root folder, then restart. On Solace, drop it in via the panel file editor or SFTP. Most version-specific settings live in the Startup tab, not this file.

Solace runs Minecraft on high-clock dedicated CPUs with NVMe storage and DDoS protection. Paper, Fabric, Forge, vanilla — live in 60 seconds.

View Minecraft Hosting

Defaults follow the official server.properties reference. Some properties (version, JAR type, RAM) are set in your host's panel, not this file. Found a bug? Tell us in Discord.
