Server Setup

Install and Setup Crafty Controller 4 (on Proxmox LXC)

1. My Server runs on a Proxmox Ubuntu LXC Container

2. Install Crafty Controller 4 according to the official Guide

Here is the TLDR Version of this Guide

• Automated Install Script (Quick)

  Please ensure your distro's packages are up-to-date and Git is present before installing Crafty:

  sudo apt update && sudo apt upgrade && sudo apt install git
  

  One line installer

  git clone https://gitlab.com/crafty-controller/crafty-installer-4.0.git && \ 
  cd crafty-installer-4.0 && \ 
  sudo ./install_crafty.sh
  

  Once installation is complete to run Crafty manually run the following. Note that if you used a directory other then the default to install Crafty you will need to cd into that directory.

  sudo su crafty
  

  cd /var/opt/minecraft/crafty
  

  ./run_crafty.sh
  

  Info

  If you said yes to adding a service file you may run the following to start Crafty

  sudo systemctl start crafty`
  

  If you added a service file and want to have Crafty start automatically on system boot please run the following:

  sudo systemctl enable crafty`
  

• now you should be able to access the Crafty Controller via https://YOUR_SERVER_IP:8443

  Default Login

  Username: admin
  Password: crafty

Create your Servers in Crafty Controller 4

• I used this Guide to create my Better MineCraft 4 Server

  • Basically it is this
    • Create a Forge Server
  • Fill out all the necessary details
  • 
    • Modded
    • forge
    • Server Version (Check the one needed from you Modpack)
    • Set the Memory (4/16 seems to work just fine)
    • Set the Server Port
    • Build Server!
  • Download the Modpack you want from Curse-Forge make sure download the Server Pack, not the regular one

  • Upload the ZIP File *

    Tip

    you might run in to the issue that it isnt uploading, that means you need to adjust the streamsize in here to 10GB or 100GB (if it is bigger the 1GB):

    location of config.json

    sudo nano /var/opt/minecraft/crafty/crafty-4/app/config/config.json
    

    

    If it didn't work

    If this didn't worked you can also use WinSCP.
    For this to work, you need to be able to login as crafty user, otherwise the permissions don't work
    Login via SSH as root, then type:

        sudo passwd crafty
    

    set a new password and use this to login to WinSCP After this, you can just add the unzipped files from the downloaded server .zip file to the server directly
    (not the .zip folder, just the files in the folder)
    If it askes you if it should override the data, you can say yes

  • when it autorefreshed and for that matter uploaded, Rightclick to extract

  • Adjust the server.properties, whitelist.json and ops.json (or do it ingame afterwords)
    • my default server.properties ( Link) are

  • Adjust the configs with the right
  • IP
  • Port
  • Autostart
  • Crash Detection and

  • Show on Public Status Page toggle

  • Go to Backups and set, how the Server gets backed up and how many Backups it keeps

    

  • and then Sheduale a Backup (i also added some Warning Messages before)

    

  Warning

  Make sure you have the proper server.properties ( Link) added before you start your server.
  If the IP in this file (most of the times it should be server-ip=192.168.X.X) is not set correctly definied, it throws an error and won't start the server.

  • Now go to the Terminal in Crafty Control, add your player to the whitelist with whitelist add <Playername> and Start the Server

Make Server Accessible from outside

• Cloudflare DDNS Updater (Docker)

  My current docker-compose.yaml

  version: "3"
  services:
  cloudflare-ddns-updater:
      image: favonia/cloudflare-ddns:latest
      network_mode: host
      cap_add:
      - SETUID # Leave this alone, as is
      - SETGID # Leave this alone, as is
      cap_drop:
      - all
      read_only: true
      security_opt:
      - no-new-privileges:true
      environment:
      - PUID=1000
      - PGID=1000
      - CF_API_TOKEN=${CF_API_TOKEN} # (1)!
      - DOMAINS=${DOMAINS} # (2)!
      - PROXIED=true
      - IP6_PROVIDER=none
      restart: unless-stopped
  

  1. The value of CF_API_TOKEN should be an API token (not an API key), which can be obtained from the API Tokens page.
     Use the Edit zone DNS template to create and copy a token into the environment file.
     (The less secure API key authentication is deliberately not supported.)
  2. Example:
     

     yourdomain.com, *.yourdomain.com`   
     

     or in the .env file
     

     DOMAINS=yourdomain.com, *.yourdomain.com
     

• This will then create the A-Record for you and keeps it up to date
