Introduction

Proxmox is an open-source virtualization management platform. This guide explains how to set up a Proxmox cluster on Hetzner servers for high availability and efficient resource management.

Prerequisites

  • Hetzner dedicated servers with Proxmox installed
  • Private network setup between the nodes
  • SSH access to the servers

Installation Steps

  1. Update System Packages:

    apt update && apt upgrade -y

  2. Set Up a Private Network: Use Hetzner's Robot or Cloud Console to configure a private network.

  3. Configure Proxmox Cluster: On the primary node, run:

    pvecm create my-cluster

    On the secondary nodes, join the cluster:

    pvecm add [IP of primary node]

  4. Test the Cluster: Ensure that all nodes are visible in the Proxmox web interface under "Datacenter".

Best Practices

  • Use RAID for disk redundancy.
  • Regularly back up your virtual machines.
  • Configure fencing to handle node failures.

Conclusion

A Proxmox cluster on Hetzner provides a powerful and flexible virtualization solution. Ensure to follow best practices for optimal performance and reliability.
