Here is a more detailed version of the process
- Download the fabric installer Installation for Minecraft Launcher | Fabric (Make sure to download the universal jar, not the windows jar)
- Run the fabric installer; click the Server tab, change Minecraft version if necessary, click Install, click Download server jar, then close the menus
- Go to downloads and delete fabric-server-launch.jar since you won’t need it
Now in MineOS, create a new server or do this process on an existing server
- Change the profile under the start button to the version of Minecraft you are using
*If it is not there download it from the profiles tab on the left - Click Copy profile to live servers
- Copy server.jar and fabric-installer-[version number].jar into the server via an sFTP program ([version number] should be something like 0.10.2)
Now open command prompt and connect to your server
*Do not include the quotations when running the following commands
- Run the command: “cd /var/games/minecraft/servers/[Your Server]” to set your directory to the Minecraft server you’re editing
-Replace [Your Server] with your server name - Run the command: “cp minecraft_server.[version].jar server.jar”
-Replace [version] with the version of Minecraft you’re using - Run the command: “java -jar fabric-installer-[version number].jar server”
-Replace [version number] with the version of the fabric installer you installed earlier
Now go back to MineOS
- Under Java Settings, change the runnable jar to “fabric-server-launch.jar”
- Start the server
- Wait a long time for the server to start
I hope this helps with the problems people were having!
