Difficulty controls hostile mob behavior, combat pressure, and survival pacing. You can change it in two clean ways: persistent config, or live command.
Pick your target before changing anything#
peaceful: no natural hostile mob pressure.easy: lighter combat pressure.normal: default survival balance.hard: highest standard survival pressure.
Detailed mechanics by mode are documented in Minecraft Wiki: Difficulty.
Method 1: Set default difficulty in server.properties (Java)#
Use this when you want the server to always boot with the same value.
- Stop the server.
- Open
server.properties. - Set:
difficulty=hard
- Save the file.
- Start the server again.
Accepted values are peaceful, easy, normal, and hard.
Reference: Minecraft Wiki: server.properties.
Method 2: Change difficulty immediately with a command#
Use this when you want to switch live without editing files.
In-game (with permission):
/difficulty hard
From console:
difficulty hard
Command reference: Minecraft Wiki: /difficulty.
Bedrock dedicated server note#
Bedrock Dedicated Server also supports difficulty in its own server.properties format, but Java and Bedrock property sets are not identical. Always edit the variant that matches your server software.
Reference: Minecraft Wiki: server.properties (Java and Bedrock variants).
Verify the change worked#
- Run
difficultyin console (or/difficultyin-game) to confirm the active value. - Check hostile mob behavior in survival gameplay.
- If behavior does not match, confirm you edited the correct server instance and restarted after property edits.
Troubleshooting quick checks#
- Change resets after restart: you used command-only and did not update
server.properties. - No effect in expected world: verify you are testing the active server and world.
- Command denied: run from console or ensure your account has permission.
