Proxmox on Hetzner Without Console Access

Automated Installation for Hetzner Dedicated Servers

📑 Overview

This project provides an automated solution for installing Proxmox VE on Hetzner dedicated servers without requiring console access. It streamlines the installation process using a custom script that handles all the complex configuration steps automatically.

Compatible Hetzner Server Series:

• AX Series
• EX Series
• SX Series

⚠️ Note: This script has been primarily tested on AX-102 servers and configures disks in RAID-1 (ZFS) format.

🚀 Installation Process

1. Prepare Rescue Mode

1. Access the Hetzner Robot Manager for your server
2. Navigate to the Rescue tab and configure:
   • Operating system: Linux
   • Architecture: 64 bit
   • Public key: optional
3. Click Activate rescue system
4. Go to the Reset tab
5. Check: Execute an automatic hardware reset
6. Click Send
7. Wait a few minutes for the server to boot into rescue mode
8. Connect via SSH to the rescue system

2. Run Installation Script

Execute this single command in the rescue system terminal:

bash <(curl -sSL https://github.com/ariadata/proxmox-hetzner/raw/main/scripts/pve-install.sh)

The script will:

• Download the latest Proxmox VE ISO
• Create an auto-installation configuration
• Install Proxmox VE with RAID-1 ZFS configuration
• Configure networking for both IPv4 and IPv6
• Set up proper hostname and FQDN
• Apply recommended system settings

3. Optional Post-Installation Optimizations

Run these commands in your Proxmox environment for additional optimizations:

# Update system packages
apt update && apt -y upgrade && apt -y autoremove && pveupgrade && pveam update

# Install useful utilities
apt install -y curl libguestfs-tools unzip iptables-persistent net-tools

# Remove subscription notice
sed -Ezi.bak "s/(Ext.Msg.show\(\{\s+title: gettext\('No valid sub)/void\(\{ \/\/\1/g" /usr/share/javascript/proxmox-widget-toolkit/proxmoxlib.js && systemctl restart pveproxy.service

Optimize ZFS Memory Usage

# Configure ZFS memory limits
echo "nf_conntrack" >> /etc/modules
echo "net.netfilter.nf_conntrack_max=1048576" >> /etc/sysctl.d/99-proxmox.conf
echo "net.netfilter.nf_conntrack_tcp_timeout_established=28800" >> /etc/sysctl.d/99-proxmox.conf
rm -f /etc/modprobe.d/zfs.conf
echo "options zfs zfs_arc_min=$[6 * 1024*1024*1024]" >> /etc/modprobe.d/99-zfs.conf
echo "options zfs zfs_arc_max=$[12 * 1024*1024*1024]" >> /etc/modprobe.d/99-zfs.conf
update-initramfs -u

✅ Accessing Your Proxmox Server

After installation completes:

1. Access the Proxmox Web GUI: https://YOUR-SERVER-IP:8006
2. Login with:
   • Username: root
   • Password: the password you set during installation

You can also refer to the notes.txt file (downloaded during installation) for additional useful information.
