How to Set a Custom World Seed on your Minecraft Server

1. Log into your Pterodactyl panel and open your Minecraft server

2. Go to the file manager

3. Find server.properties and open it

4. Find and add your seed in the field level-seed=Your seed
For example – level-seed=12906402

5. After changing the seed, click on Save Content and restart your server.

Please note, the new seed will only affect newly loaded chunks. If you wish for your entire world to change seed, you need to delete your world folder – this will remove all of your game progress and start fresh.
