Proxmox Preparation

  1. System Requirements

    • CPU: x86_64 architecture required
    • RAM: Minimum 8GB (16GB+ recommended)
    • Storage: SSD recommended
    • Network: Gigabit Ethernet recommended

  2. Download MineOS Turnkey

MineOS Turnkey Installation

  1. Create VM in Proxmox

    General:
- Node: your-node
- VM ID: 100 (or available ID)
- Name: mineos-turnkey

OS:
- Use CD/DVD: MineOS-Turnkey.iso
- Type: Linux
- Version: Debian 11

System:
- Machine: q35
- BIOS: OVMF (UEFI)
- EFI Storage: local-lvm
- SCSI Controller: VirtIO SCSI

Disks:
- Bus/Device: SCSI
- Storage: local-lvm
- Disk size: 32GB minimum
- Cache: Write back

CPU:
- Cores: 4 (adjust as needed)
- Type: host

Memory:
- Size: 8GB minimum
- Ballooning Device: Disabled

Network:
- Bridge: vmbr0
- Model: VirtIO

  2. Install MineOS Turnkey

    • Start VM and access console
    • Follow Turnkey installation prompts:
      Set root password
Set MySQL password
Set webmin admin password
Configure email settings (optional)

Initial Configuration

  1. First Login

    Web Interface:
URL: https://your-server-ip:8443
Default credentials will be shown in console after installation

SSH Access:
ssh root@your-server-ip

  2. Update System

    apt update
apt upgrade -y

  3. Configure Backup Location

    mkdir -p /var/backups/minecraft
chmod 755 /var/backups/minecraft

Multiple Server Setup

  1. Access Web Interface

  2. Create Minecraft Servers

    For each server:
1. Click "Create New Server"
2. Configure unique settings:
   - Server Name
   - Port Number (increment from 25565)
   - Memory Allocation
   - Minecraft Version

  3. Server Configuration Template

    # server.properties
server-port=25565      # Increment for each server
max-players=20
view-distance=10
spawn-protection=16
allow-nether=true
difficulty=normal

  4. Resource Allocation

    Server 1 (Main):
  Port: 25565
  RAM: 4GB
  CPU Cores: 2

Server 2:
  Port: 25566
  RAM: 2GB
  CPU Cores: 1

Server 3:
  Port: 25567
  RAM: 2GB
  CPU Cores: 1

Network Configuration

  1. Turnkey Firewall Configuration

    # Edit /etc/csf/csf.conf
# Allow Minecraft ports
TCP_IN = "8443,25565:25570"
TCP_OUT = "8443,25565:25570"

# Restart firewall
csf -r

  2. Port Forwarding

    Router/Firewall Settings:
- TCP 8443 (Web Interface)
- TCP 25565 (Minecraft Server 1)
- TCP 25566 (Minecraft Server 2)
- TCP 25567 (Minecraft Server 3)

Performance Optimization

  1. Java Settings per Server

    # Edit in MineOS Web Interface for each server
java_xms=1G
java_xmx=4G

# Additional JVM arguments
-XX:+UseG1GC
-XX:+ParallelRefProcEnabled
-XX:MaxGCPauseMillis=200
-XX:+UnlockExperimentalVMOptions
-XX:+DisableExplicitGC
-XX:+AlwaysPreTouch
-XX:G1NewSizePercent=30
-XX:G1MaxNewSizePercent=40
-XX:G1HeapRegionSize=8M
-XX:G1ReservePercent=20

  2. Scheduled Tasks

    # Automatic backups (via webmin)
0 4 * * * /usr/local/games/minecraft/backup.sh

# Memory cleanup
0 */6 * * * sync; echo 3 > /proc/sys/vm/drop_caches

  3. System Monitoring

    • Use built-in Webmin monitoring
    • Enable MineOS server statistics
    • Monitor through Proxmox interface

Maintenance Procedures

  1. Regular Backups

    # Configure in Webmin:
Scheduled Backups:
- World files
- Server configurations
- Player data

  2. Update Schedule

    Weekly:
- Check for Minecraft updates
- System updates (apt upgrade)

Monthly:
- Review logs
- Clean old backups
- Check resource usage

  3. Recovery Procedures

    • Keep latest known-good backup
    • Document all custom configurations
    • Maintain server-specific restore points

Additional Notes

  • MineOS Turnkey includes Webmin for additional server management
  • Use SFTP for file transfers (available by default)
  • Monitor server logs through web interface
  • Utilize MineOS’s built-in server templates
  • Keep system updated using apt package manager

Troubleshooting

  • Check logs in /var/log/mineos
  • Monitor system resources with Webmin
  • Use htop for real-time resource monitoring
  • Check network connectivity with netstat -tulpn

Remember to:

  • Regularly backup all server data
  • Monitor system resources
  • Keep MineOS and system updated
  • Document any custom configurations
  • Test backups periodically
