Minecraft Server

Run Minecraft as a public server on Ubuntu without public ip or port forward over ZeroTier Network or via mods

Server Requirements

• Docker
• Java 21 (JDK)
• ZeroTier (optional)

HOW IT WORK

I use Google Cloud Shell as a server in this guide

ZeroTier setup

• Create ZeroTier Network (you need an account), see docs
• On your local machine, install ZeroTier and join the network you just created
• Log in to your google cloud shell and run: git clone https://github.com/TTlaugh/mcsv.git

Mods setup

By default, e4mc mod is already added to fabric server, so you don't need to do anything.

Note: you can use either zerotier or mod and you can use both if you like.

Run server

• Inside mcsv folder, run:

  chmod +x mcsv && ./mcsv -z fabric/1.20.1

• Then you need to authenticate every time you join a device to a ZeroTier Network if the network you created is private.
• Finally, follow the console log to get the address of your server, it should look like this:

  ╭─────────────────────────╮
  │ ZeroTier ip: 172.25.0.1 │
  ╰─────────────────────────╯
  
  # .... Some log lines
  
  ╭─────────────────────────────────────────╮
  │ e4mc address: pyramid-news.ap.e4mc.link │
  ╰─────────────────────────────────────────╯

Options

Note: run script without -z flag will only run Minecraft server jar file

Run:
    mcsv [OPTIONS...] PATH
PATH:
    The path of the folder contain server .jar file
OPTION:
    -z      start and join the Server to ZeroTier-Network
    -r      delete existing world and start Server
