Server.properties

is the file that 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 file, the server must be restarted for them to take effect. Another option is to use the command in the server console or in-game, which will also allow changes to be reloaded.
If the 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.
The file is simply a normal text file with UTF-8 encoding, despite its extension, and can therefore be edited with any text editor such as Notepad for Windows, TextEdit for Mac, or nano and vim for Linux.
== Java Edition ==
=== File location ===
This file is automatically generated upon the first start of the server (if it does not exist).
OS 	File Location 	Notes
Windows	In the Working Directory (Defaults to the same folder as )	If the player starts the server by clicking on either , a startup script in the same folder, or a shortcut to either of these, then the Working Directory is set to the same folder as .
Linux
Unix
Unix/Mac	Path of Working Directory (pwd) 	
If the player starts it from their home directory () the server files are created in /home/name. Follow these guidelines for ensuring that the server files are generated where the player would expect them.
* Set aside an entire directory for all of the server files. (Things could get messy if the player doesn't).
** The player's server.jar should be placed here.
* Use this script as a guideline for setting up a startup script for the Minecraft server.
** It should be in the player's executable 
** Be sure to add the execution permission to the startup script (chmod +x file_name, or use a folder manager)

=== Keys ===
Key 	Type 	Default Value 	Description
allow-flight 	boolean 	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.
:false - Flight is not allowed (players in air for at least 5 seconds get kicked).
:true - Flight is allowed, and used if the player has a fly mod installed.
allow-nether 	boolean 	true 	Allows players to travel to the Nether.
:false - Nether portals do not work.
:true - The server allows portals to send players to the Nether.
broadcast-console-to-ops 	boolean 	true 	Send console command outputs to all online operators.
broadcast-rcon-to-ops 	boolean 	true 	Send rcon console command outputs to all online operators.
difficulty 	string 	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.
:peaceful (0)
:easy (1)
:normal (2)
:hard (3)
enable-command-block 	boolean 	false 	Enables command blocks
enable-jmx-monitoring 	boolean 	false 	Exposes an MBean with the Object name net.minecraft.server:type=Server and two attributes averageTickTime and tickTimes exposing the tick times in milliseconds.
In order for enabling JMX on the Java runtime you also need to add a couple of JVM flags to the startup as documented here.
enable-rcon 	boolean 	false 	Enables remote access to the server console.
* It's not recommended to expose RCON to the Internet, because RCON protocol transfers everything without encryption. Everything (including RCON password) communicated between the RCON server and client can be leaked to someone listening in on your connection.
enable-status 	boolean 	true 	Makes the server appear as "online" on the server list.
If set to false, it will suppress replies from clients. This means it will appear as offline, but will still accept connections.
enable-query 	boolean 	false 	Enables GameSpy4 protocol server listener. Used to get information about server.
enforce-secure-profile 	boolean 	true 	If set to true, players without a Mojang-signed public key will not be able to connect to the server.
enforce-whitelist 	boolean 	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.
:false - No user gets kicked if not on the whitelist.
:true - Online users not on the whitelist get kicked.
entity-broadcast-range-percentage	integer (10-1000) 	100 	Controls how close entities need to be before being sent to clients. Higher values means they'll be rendered from farther away, potentially causing more lag. This is expressed the percentage of the default value. For example, setting to 50 will make it half as usual. This mimics the function on the client video settings (not unlike Render Distance, which the client can customize so long as it's under the server's setting).
force-gamemode 	boolean 	false 	Force players to join in the default game mode.
:false - Players join in the gamemode they left in.
:true - Players always join in the default gamemode.
function-permission-level 	integer (1-4) 	2 	Sets the default permission level for functions.
See permission level for the details on the 4 levels.
gamemode 	string 	survival 	Defines the mode of gameplay.
If a legacy gamemode number is specified, it is silently converted to a gamemode name.
:survival (0)
:creative (1)
:adventure (2)
:spectator (3)
generate-structures 	boolean 	true 	Defines whether structures (such as villages) can be generated.
:false - Structures are not generated in new chunks.
:true - Structures are generated in new chunks.
Note: Dungeons still generate if this is set to false.
generator-settings 	string 	{} 	The settings used to customize world generation. Follow its format and write the corresponding JSON string. Remember to escape all : with \:.
hardcore 	boolean 	false 	If set to true, server difficulty is ignored and set to hard and players are set to spectator mode if they die.
hide-online-players 	boolean 	false 	If set to true, a player list is not sent on status requests.
initial-disabled-packs 	string 	blank 	Comma-separated list of datapacks to not be auto-enabled on world creation.
initial-enabled-packs 	string 	vanilla 	Comma-separated list of datapacks to be enabled during world creation. Feature packs need to be explicitly enabled.
level-name 	string 	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.
:Characters such as ' (apostrophe) may need to be escaped by adding a backslash before them.
level-seed 	string 	blank 	Sets a world seed for the player's world, as in Singleplayer. The world generates with a random seed if left blank.
:Some examples are: minecraft, 404, 1a2b3c.
level-type 	string 	minecraft:normal 	Determines the world preset that is generated.
Escaping ":" is required when using a world preset ID, and the vanilla world preset ID's namespace () can be omitted.
:minecraft:normal - Standard world with hills, valleys, water, etc.
:minecraft:flat - A flat world with no features, can be modified with generator-settings.
:minecraft:large_biomes - Same as default but all biomes are larger.
:minecraft:amplified - Same as default but world-generation height limit is increased.
:minecraft:single_biome_surface - A buffet world which the entire overworld consists of one biome, can be modified with generator-settings.
:buffet - Only for 1.15 or before. Same as default unless generator-settings is set.
:default_1_1 - Only for 1.15 or before. Same as default, but counted as a different world type.
:customized - Only for 1.15 or before. After 1.13, this value is no different than default, but in 1.12 and before, it could be used to create a completely custom world.
max-chained-neighbor-updates 	integer 	1000000 	Limiting the amount of consecutive neighbor updates before skipping additional ones. Negative values remove the limit.
max-players 	integer (0-(2^31 - 1)) 	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.
max-tick-time 	integer (-1 or 0–(2^63 - 1))	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).
:-1 - disable watchdog entirely (this disable option was added in 14w32a)
max-world-size 	integer (1-29999984) 	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. 
Examples: 
*Setting max-world-size to 1000 allows the player to have a 2000×2000 world border.
*Setting max-world-size to 4000 gives the player an 8000×8000 world border.
motd 	string 	A Minecraft Server	This is the message that is displayed in the server list of the client, below the name.
* The MOTD supports color and formatting codes.
* The MOTD supports special characters, such as "♥". However, such characters must be converted to escaped Unicode form. An online converter can be found here.
* If the MOTD is over 59 characters, the server list may report a communication error.
network-compression-threshold 	integer 	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.
:-1 - disable compression entirely
:0 - compress everything
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.
online-mode 	boolean 	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.
:true - Enabled. The server assumes it has an Internet connection and checks every connecting player.
:false - Disabled. The server does not attempt to check connecting players.
op-permission-level 	integer (0-4) 	4 	Sets the default permission level for ops when using .
player-idle-timeout 	integer 	0 	If non-zero, players are kicked from the server if they are idle for more than that many minutes. 
:Note: Idle time is reset when the server receives one of the following packets:
:*Click Window
:*Enchant Item
:*Update Sign
:*Player Digging
:*Player Block Placement
:*Held Item Change
:*Animation (swing arm)
:*Entity Action
:*Client Status
:*Chat Message
:*Use Entity
prevent-proxy-connections 	boolean 	false 	If the ISP/AS sent from the server is different from the one from Mojang Studios' authentication server, the player is kicked.
previews-chat 	boolean 	false 	If set to true, chat preview will be enabled.
:true - Enabled. When enabled, a server-controlled preview appears above the chat edit box, showing how the message will look when sent.
:false - Disabled.
pvp 	boolean 	true 	Enable PvP on the server. Players shooting themselves with arrows receive damage only if PvP is enabled.
:true - Players can kill each other.
:false - Players cannot kill other players (also known as Player versus Environment (PvE)).
Note: Indirect damage sources spawned by players (such as lava, fire, TNT and to some extent water, sand and gravel) still deal damage to other players.
query.port 	integer (1-(2^16 - 2)) 	25565 	Sets the port for the query server (see enable-query).
rate-limit 	integer 	0 	Sets the maximum amount of packets a user can send before getting kicked. Setting to 0 disables this feature.
rcon.password 	string 	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.
rcon.port 	integer (1-(2^16 - 2)) 	25575 	Sets the RCON network port.
resource-pack 	string 	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 250 MiB (Before 1.18: 100 MiB (≈ 100.8 MB)) (Before 1.15: 50 MiB (≈ 50.4 MB)). Note that download success or failure is logged by the client, and not by the server.
resource-pack-prompt 	string 	blank 	
Optional, adds a custom message to be shown on resource pack prompt when require-resource-pack is used.
Expects chat component syntax, can contain multiple lines.
resource-pack-sha1 	string 	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.
require-resource-pack 	boolean 	false 	When this option is enabled (set to true), players will be prompted for a response and will be disconnected if they decline the required pack.
server-ip 	string 	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.
:Set to blank, or the IP the player want their server to run (listen) on.
server-port 	integer (1-(2^16 - 2)) 	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).
simulation-distance 	integer (3-32) 	10 	Sets the maximum distance from players that living entities may be located in order to be updated by the server, measured in chunks in each direction of the player (radius, not diameter). If entities are outside of this radius, then they will not be ticked by the server nor will they be visible to players.
10 is the default/recommended. If the player has major lag, this value is recommended to be reduced.
snooper-enabled 	boolean 	true 	Sets whether the server sends snoop data regularly to http://snoop.minecraft.net.
:false - disable snooping.
:true - enable snooping.
spawn-animals 	boolean 	true 	Determines if animals can spawn.
:true - Animals spawn as normal.
:false - Animals immediately vanish.
If the player has major lag, it is recommended to turn this off/set to false.
spawn-monsters 	boolean 	true 	Determines if monsters can spawn.
:true - Enabled. Monsters appear at night and in the dark.
:false - Disabled. No monsters.
This setting has no effect if difficulty = 0 (peaceful). If difficulty is not = 0, a monster can still spawn from a monster spawner.
If the player has major lag, it is recommended to turn this off/set to false.
spawn-npcs 	boolean 	true 	Determines whether villagers can spawn.
:true - Enabled. Villagers spawn.
:false - Disabled. No villagers.
spawn-protection 	integer 	16 	Determines the side length of the square spawn protection area as 2x+1. Setting this to 0 disables the spawn protection. 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 as well.
sync-chunk-writes 	boolean 	true 	Enables synchronous chunk writes.
text-filtering-config 	 	blank 	
use-native-transport 	boolean 	true 	Linux server performance improvements: optimized packet sending/receiving on Linux
:true - Enabled. Enable Linux packet sending/receiving optimization
:false - Disabled. Disable Linux packet sending/receiving optimization
view-distance 	integer (3-32) 	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.
white-list 	boolean 	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.
:false - No white list is used.
:true - The file whitelist.json is used to generate the white list.
Note: Ops are automatically whitelisted, and there is no need to add them to the whitelist.

online-mode 	true, false 	true 	Always 	If true then all connected players must be authenticated to Xbox Live. 	
player-idle-timeout 	Any integer 	30 	Always 	After a player has idled for this many minutes they get kicked. 	
player-movement-distance-threshold 	Any positive number 	0.3 	Always 	The difference between server and client positions that needs to be exceeded before abnormal behavior is detected. 	Disabled by server-authoritative-movement.
player-movement-duration-threshold-in-ms	Any positive integer 	500 	Always 	The duration of time the server and client positions can be out of sync (as defined by player-movement-distance-threshold) before the abnormal movement score is incremented. This value is defined in milliseconds. 	Disabled by server-authoritative-movement.
player-movement-score-threshold 	Any positive integer 	20 	Always 	The number of incongruent time intervals needed before abnormal behavior is reported. 	Disabled by server-authoritative-movement.
server-authoritative-block-breaking 	true, false 	false 	Always 	If true, the server will compute block mining operations in sync with the client so it can verify that the client should be able to break blocks when it thinks it can. 	
server-authoritative-movement 	client-auth, server-auth, server-auth-with-rewind	server-auth 	Always 	Enables server authoritative movement. If server-auth, the server will replay local user input on the server and send down corrections when the client's position doesn't match the server's. If "server-auth-with-rewind" is enabled and the server sends a correction, the clients will be instructed to rewind time back to the correction time, apply the correction, then replay all the player's inputs since then. This results in smoother and more frequent corrections.	Corrections will only happen if correct-player-movement is set to server-auth.
server-name 	Any string 	Dedicated Server 	Always 	Used as the server name. Cannot contain a ":" (colon). 	This is the server name shown in the in-game server list.
server-port 	Integers in the range [1, 65535] 	19132 	Always 	Which IPv4 port the server should listen to. 	
server-portv6 	Integers in the range [1, 65535] 	19133 	Always 	Which IPv6 port the server should listen to. 	
texturepack-required 	true, false 	false 	Always 	Force clients to use texture packs in the current world 	
tick-distance 	An integer in the range [4, 12] 	4 	Always 	The world is ticked this many chunks away from any player. 	Higher values have performance impact.
view-distance 	Any positive integer greater than or equal to 5 	32 	Always 	The maximum allowed view distance in number of chunks. 	Higher values have performance impact.
== Minecraft Classic server properties ==
Key 	Type 	Default Value	Description
admin-slot 	boolean 	false 	Allow ops to join even if the server is full.
grow-trees 	boolean 	 	Whether or not the server allows planted saplings to grow into trees.
:true - the server allows saplings to grow into trees.
:false - the server does not allow saplings to grow into trees.
max-connections	integer (1-3) 	 	The max number of connections the server accepts from the same IP.
Note: If set higher than 3, it is changed back to 3.
max-players 	integer (0-256)	 	The max numbers of players that can play on the server at the same time. Note that if more players are on the server it uses more resources. Note also, admin connections are not counted against the max players.
motd 	string 	 	MOTD is short for Message of the day, though the player does not need to change it every day. The MOTD is displayed when people join the server.
public 	boolean 	 	Whether the server should be displayed in the server list, or not.
:true - The server appears in the server list - anyone can see it.
:false - Only people with the URL that can be found in externalurl.txt and people who know the IP and port can join the server
server-name 	string 	 	The name of the server. This is displayed in the server list and when someone is joining the server
* A single line of text. Characters such as ' (apostrophe) may need to be escaped by adding a backslash before them.
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.
:true - Enabled. The server checks all names with Minecraft.net
:false - Disabled. The server makes sure the IP matches
