server.properties is the file stores all the settings for a multiplayer (Minecraft or Minecraft Classic) server.
When editing server.properties it is important that the same structure as the original is used, although the order of the lines is arbitrary. The text before the equal sign is the key, which should not be changed. The text after the equal sign is the property's value, which can be edited. Lines that begin with
# are comments – altering or removing these lines has no effect on the game.
After changes are made to the server.properties file, the server must be restarted for them to take effect. Another option is to use the
/reload command in the server console, which will also allow changes to be made.
If the server.properties file does not list all properties (such as if a new version of the server adds new properties, or if the file does not exist), then on startup, the server rewrites the server.properties file with the new properties listed and set them to their default values.
This file is automatically generated upon the first start of the server (if it doesn't exist).

Minecraft server properties
|boolean||allow-flight||false|| Allows users to use flight on the server while in Survival mode, if they have a mod that provides flight installed.
With allow-flight enabled, griefers may become more common, because it makes their work easier. In Creative mode, this has no effect.
|boolean||allow-nether||true||Allows players to travel to the Nether.|
|string||difficulty||easy|| Defines the difficulty (such as damage dealt by mobs and the way hunger and poison affects players) of the server.
If a legacy difficulty number is specified, it is silently converted to a difficulty name.
|boolean||enable-command-block||false||Enables command blocks|
|boolean||enable-rcon||false||Enables remote access to the server console.|
|boolean||sync-chunk-writes||true||Enables synchronous chunk writes.|
|boolean||enable-query||false||Enables GameSpy4 protocol server listener. Used to get information about server.|
|boolean||force-gamemode||false|| Force players to join in the default game mode.
|integer (1-4)||function-permission-level||2|| Sets the default permission level for functions.
See #op-permission-level for the details on the 4 levels.
|string||gamemode||survival|| Defines the mode of gameplay.
If a legacy gamemode number is specified, it is silently converted to a gamemode name.
|boolean||generate-structures||true|| Defines whether structures (such as villages) can be generated.
Note: Dungeons still generate if this is set to false.
|string||generator-settings||blank||The settings used to customize world generation. See Superflat and Customized for possible settings and examples.|
|boolean||hardcore||false||If set to true, server difficulty is ignored and set to hard and players are set to spectator mode if they die.|
|string||level-name||world|| The "level-name" value is used as the world name and its folder name. The player may also copy their saved game folder here, and change the name to the same as that folder's to load it instead.
|string||level-seed||blank|| Add a seed for the player's world, as in Singleplayer.
|string||level-type||default|| Determines the type of map that is generated.
|integer||max-build-height||256||The maximum height allowed for building. Terrain may still naturally generate above a low height limit.|
|integer (0-2147483647)||max-players||20||The maximum number of players that can play on the server at the same time. Note that more players on the server consume more resources. Note also, op player connections are not supposed to count against the max players, but ops currently cannot join a full server. However, this can be changed by going to the file called ops.json in the player's server directory, opening it, finding the op that the player wants to change, and changing the setting called bypassesPlayerLimit to true (the default is false). This means that that op does not have to wait for a player to leave in order to join. Extremely large values for this field result in the client-side user list being broken.|
|integer (0–(2^63 - 1))||max-tick-time
||60000|| The maximum number of milliseconds a single tick may take before the server watchdog stops the server with the message, A single server tick took 60.00 seconds (should be max 0.05); Considering it to be crashed, server will forcibly shutdown. Once this criterion is met, it calls System.exit(1).
||29999984|| This sets the maximum possible size in blocks, expressed as a radius, that the world border can obtain. Setting the world border bigger causes the commands to complete successfully but the actual border does not move past this block limit. Setting the max-world-size higher than the default doesn't appear to do anything.
|string||motd||A Minecraft Server||This is the message that is displayed in the server list of the client, below the name.|
||256|| By default it allows packets that are n-1 bytes big to go normally, but a packet of n bytes or more gets compressed down. So, a lower number means more compression but compressing small amounts of bytes might actually end up with a larger result than what went in.
Note: The Ethernet spec requires that packets less than 64 bytes become padded to 64 bytes. Thus, setting a value lower than 64 may not be beneficial. It is also not recommended to exceed the MTU, typically 1500 bytes.
|boolean||online-mode||true|| Server checks connecting players against Minecraft account database. Set this to false only if the player's server is not connected to the Internet. Hackers with fake accounts can connect if this is set to false! If minecraft.net is down or inaccessible, no players can connect if this is set to true. Setting this variable to off purposely is called "cracking" a server, and servers that are present with online mode off are called "cracked" servers, allowing players with unlicensed copies of Minecraft to join.
|integer (1-4)||op-permission-level||4|| Sets the default permission level for ops when using |
|integer||player-idle-timeout||0||If non-zero, players are kicked from the server if they are idle for more than that many minutes.|
|boolean||prevent-proxy-connections||false||If the ISP/AS sent from the server is different from the one from Mojang's authentication server, the player is kicked
|boolean||pvp||true|| Enable PvP on the server. Players shooting themselves with arrows receive damage only if PvP is enabled.
|integer (1-65534)||query.port||25565||Sets the port for the query server (see enable-query).|
|string||rcon.password||blank||Sets the password for RCON: a remote console protocol that can allow other applications to connect and interact with a Minecraft server over the internet.|
|integer (1-65534)||rcon.port||25575||Sets the RCON network port.|
|string||resource-pack||blank|| Optional URI to a resource pack. The player may choose to use it.
Note that (in some versions before 1.15.2), the ":" and "=" characters need to be escaped with a backslash (\), e.g. http\://somedomain.com/somepack.zip?someparam\=somevalue
The resource pack may not have a larger file size than 50 MiB (≈ 50.4 MB). Note that download success or failure is logged by the client, and not by the server.
||blank|| Optional SHA-1 digest of the resource pack, in lowercase hexadecimal. It is recommended to specify this, because it is used to verify the integrity of the resource pack.
Note: If the resource pack is any different, a yellow message "Invalid sha1 for resource-pack-sha1" appears in the console when the server starts. Due to the nature of hash functions, errors have a tiny probability of occurring, so this consequence has no effect.
|string||server-ip||blank|| The player should set this if they want the server to bind to a particular IP. It is strongly recommended that the player leaves server-ip blank.
|integer (1-65534)||server-port||25565||Changes the port the server is hosting (listening) on. This port must be forwarded if the server is hosted in a network using NAT (if the player has a home router/firewall).|
|boolean||snooper-enabled||true|| Sets whether the server sends snoop data regularly to http://snoop.minecraft.net.
|boolean||spawn-animals||true|| Determines if animals can spawn.
If the player has major lag, it is recommended to turn this off/set to false.
|boolean||spawn-monsters||true|| Determines if monsters can spawn.
This setting has no effect if difficulty = 0 (peaceful). If difficulty is not = 0, a monster can still spawn from a spawner.
If the player has major lag, it is recommended to turn this off/set to false.
|boolean||spawn-npcs||true|| Determines whether villagers can spawn.
|integer||spawn-protection||16||Determines the side length of the square spawn protection area as 2x+1. Setting this to 0 does not disable spawn protection, but protects the single block at the spawn point. A value of 1 protects a 3×3 square centered on the spawn point. 2 protects 5×5, 3 protects 7×7, etc. This option is not generated on the first server start and appears when the first player joins. If there are no ops set on the server, the spawn protection is disabled automatically.|
|boolean||use-native-transport||true|| Linux server performance improvements: optimized packet sending/receiving on Linux
|integer (3-32)||view-distance||10|| Sets the amount of world data the server sends the client, measured in chunks in each direction of the player (radius, not diameter). It determines the server-side viewing distance.
10 is the default/recommended. If the player has major lag, this value is recommended to be reduced.
Note: A value less than 9 has a big impact on mob spawning on the server, as noted in bug .
|boolean||white-list||false|| Enables a whitelist on the server.
With a whitelist enabled, users not on the whitelist cannot connect. Intended for private servers, such as those for real-life friends or strangers carefully selected via an application process, for example.
Note: Ops are automatically whitelisted, and there is no need to add them to the whitelist.
|boolean||enforce-whitelist||false|| Enforces the whitelist on the server.
When this option is enabled, users who are not present on the whitelist (if it's enabled) get kicked from the server after the server reloads the whitelist file.
In versions prior to Java Edition 1.12, the announce-player-achievements boolean property (default true) was used to toggle whether achievements were broadcasted to all players. This property no longer exists, but if it is set, the
announceAdvancements gamerule is automatically updated to match, and the property is removed.

Minecraft Classic server properties
|verify-names||boolean||true||If enabled, the server ensures that the client is logged in with the same IP address seen on Minecraft.net. This has caused problems for people trying to play on the same computer they are hosting the server on as the server sees the local IP (127.0.0.1) while Minecraft.net sees the external IP. It is recommended that this is enabled unless the player want to play on the player's server from the same computer the player is hosting it on.
