Introduction

This tutorial guides you through the process of completely reinstalling your Proxmox server, based on the insights from Zatoufly's YouTube video. Whether you're upgrading or setting up a new server, this step-by-step guide will ensure a smooth transition, covering backup, installation, configuration, and restoration of virtual machines.

Step 1: Plan Your Project

• Understand the purpose of your Proxmox server and what you hope to achieve with the reinstallation.
• Determine if you need to keep existing configurations or if you're starting fresh.
• Make a checklist of necessary tasks and the resources you will need.

Step 2: Make a Backup

• Before proceeding with the reinstallation, perform a backup of your current Proxmox setup.
• Follow these steps for a successful backup:
  • Access the Proxmox web interface.
  • Select the virtual machines (VMs) or containers you wish to back up.
  • Use the backup feature to create a snapshot. Choose the storage location and format (usually best to use VMA format).
• Verify that the backup is complete and stored securely.

Step 3: Install the New Proxmox

• Download the latest Proxmox installer from the official website.
• Create a bootable USB drive with the downloaded ISO file using tools like Rufus or Etcher.
• Boot your server from the USB drive and follow these steps:
  • Select "Install Proxmox VE" from the boot menu.
  • Accept the license agreement and select the target hard drive for installation.
  • Configure your desired settings, such as timezone and network settings (static IP recommended).
• Complete the installation and reboot the server.

Step 4: Configure Network Interfaces

• After installation, log in to the Proxmox web interface.
• Navigate to the network settings:
  • Set up the network interfaces as needed (e.g., bridge mode for VMs).
  • Ensure that the correct IP addresses and subnet masks are configured.
• Test the network connectivity to ensure everything is correctly set up.

Step 5: Update Proxmox VE

• Keeping your Proxmox installation updated is crucial for security and performance.
• Run the following commands in the terminal to update:

  apt update
  apt full-upgrade
  

• Reboot the server after the updates are installed.

Step 6: Configure NFS Storage

• If you're using NFS for storage, configure it as follows:
  • Go to the Datacenter view in the Proxmox web interface.
  • Select "Storage" and add an NFS storage.
  • Input the server's IP address and export path.
• Verify the connection to ensure Proxmox can access the NFS storage.

Step 7: Restore Virtual Machines

• With your new Proxmox setup ready, it's time to restore your VMs.
• Use the following steps:
  • Go to the Backup section in the Proxmox web interface.
  • Select the backup file you created earlier.
  • Choose to restore the VM or container by following the prompts, ensuring you select the correct storage location.
• Verify that all VMs are functioning as expected post-restoration.

Conclusion

By following these steps, you can effectively reinstall your Proxmox server from scratch while preserving your important data and configurations. Make sure to regularly back up your server and keep it updated. For ongoing management, consider exploring additional features of Proxmox to enhance your home lab setup.
