The default server.properties file for Java Edition.

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 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 or in-game, which will also allow changes to be reloaded.

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.

The server.properties 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.

File location

Java Edition

This file is automatically generated upon the first start of the server (if it doesn't exist).

OS File Location Notes
Windows Same directory as server.jar
Linux

Unix Unix/Mac

Path of Working Directory (pwd)

If the player starts it from their home directory (\home\name) 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 $PATH
    • Be sure to add the execution permission to the startup script (chmod +x file_name, or use a folder manager)
      • minecraft_server.sh

Minecraft server properties

Java Edition

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.
sync-chunk-writes boolean true Enables synchronous chunk writes.
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.
entity-broadcast-range-percentage integer (0-500) 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 #op-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 blank 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.
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 default Determines the type of map that is generated.
default - Standard world with hills, valleys, water, etc.
flat - A flat world with no features, can be modified with generator-settings.
largeBiomes - Same as default but all biomes are larger.
amplified - Same as default but world-generation height limit is increased.
buffet - Only for 1.15 or before. Same as default unless generator-settings is set.
max-build-height integer 256 The maximum height allowed for building. Terrain may still naturally generate above a low height limit. 256 is the maximum possible, it also has to be a multiple of 8.
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 (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 (1-4) 4 Sets the default permission level for ops when using /op. All levels inherit abilities and commands from levels before them.
1 - Ops can bypass spawn protection.
2 - Ops can use all singleplayer cheats commands (except /publish, as it is not on servers; along with /debug) and use command blocks. Command blocks, along with Realms owners/operators, have the same permissions as this level.
3 - Ops can use most multiplayer-exclusive commands, including /debug, and commands that manage players (/ban, /op, etc).
4 - Ops can use all commands including /stop, /save-all, /save-on, and /save-off.
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:
prevent-proxy-connections boolean false If the ISP/AS sent from the server is different from the one from Mojang's authentication server, the player is kicked
true - Enabled. Server prevents users from using vpns or proxies.
false - Disabled. The server doesn't prevent users from using vpns or proxies.
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 100 MiB (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-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.

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).
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 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.
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.

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.

Minecraft Classic server properties

Key Type Default Value Description
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
admin-slot boolean false Allow ops to join even if the server is full.
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.
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.
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.

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.
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.
