=== Setup Instance ===
Now you can Upload your FTB Modpacks into an subfolder of /opt/minecraft/. For example, you would place the modpack "FTB Beyond" in "/opt/minecraft/FTBBeyond" (without spaces in the name).
If you want to run vanilla instances, just create a folder within /opt/minecraft and upload the minecraft_server.jar and create the eula.txt file (using: echo "eula=true" > /opt/minecraft/vanilla/eula.txt).

After you uploaded the minecraft server files, make sure, that "minecraft" is the owner and owning group. To do so just run "ls -la /opt/minecraft". If it is not, run "chown minecraft:minecraft /opt/minecraft/FTBBeyond".
You may also require to complete the installation. For current FTB packages you would run:
<pre>
cd /opt/minecraft/FTBBeyond
echo "eula=true" > /opt/minecraft/FTBBeyond/eula.txt
su -c "/opt/minecraft/FTBBeyond/FTBInstall.sh" -s "/bin/bash" minecraft
</pre>
