How to set a custom seed on your Minecraft Server
- Make sure your server is not running. If it is running, stop the server
- Go to the File Manager tab, and delete the “world” folder if there is one.
- Open the
server.properties
file in the File Manager and look for the “level-seed” option (or add it, in case the option does not exist), then enter the seed that you wanted and save the file. - Start the server and wait for your new world to generate using the seed.
