Download the latest Proxmox VE ISO from the official website. Use tools like Rufus (Windows) or dd (Linux) to create a bootable USB drive.
Step 2: Install Proxmox VE
Boot from the USB and follow the installation wizard. Key decisions include:
- Choose your target disk (consider ZFS RAID for redundancy)
- Set a strong root password
- Configure network settings (static IP recommended)
Step 3: Access the Web Interface
After installation, access Proxmox at https://YOUR-IP:8006. Accept the self-signed certificate warning and log in with root credentials.
Essential Post-Installation Configuration
Remove Enterprise Repository (For Home Labs)
Edit the apt sources to use the no-subscription repository:
nano /etc/apt/sources.list.d/pve-no-subscription.listConfigure Storage
Set up your storage pools for VM disks, ISO images, and backups. ZFS is highly recommended for data integrity and snapshots.
Create Your First Virtual Machine
Upload an ISO, create a new VM, and start experimenting! Popular choices for home labs include:
- pfSense/OPNsense - Firewall and routing
- TrueNAS - Network-attached storage
- Ubuntu Server - General-purpose Linux
- Windows Server - Active Directory lab
Best Practices for Home Lab Success
