How to Install Proxmox VE on Bare Metal Step-by-Step

The step-by-step guide on this page will show you how to Install Proxmox VE on bare metal.

Proxmox Virtual Environment (VE) is a powerful, open-source platform for managing virtual machines (VMs) and containers. It combines two virtualization technologies, KVM (Kernel-based Virtual Machine) for virtual machines and LXC (Linux Containers) for lightweight containerization. Installing Proxmox VE on bare metal provides a solid foundation for building a virtualization infrastructure that can efficiently manage your workloads.

Prerequisites

• A bare metal server with hardware virtualization support (Intel VT-x/AMD-V).
• A bootable USB drive with the Proxmox VE ISO image.
• Access to the server’s management interface (e.g., IPMI, iDRAC, or a physical console).
• Basic knowledge of Linux commands.

1) Download Proxmox VE ISO Installer

Click Next

7) Network Configuration

Next, you’ll need to configure the network settings for Proxmox VE. Set FQDN, static IP address, subnet mask, gateway, and DNS server. Ensure that you specify the correct network configuration according to your environment.

Click Next to proceed further with the installation.

8) Begin Proxmox VE Installation

Review your installation settings one last time.

If everything looks correct, click on “Install“. The installation process will begin, and Proxmox VE will be installed on your bare metal server.

Once the installation is complete, server will be rebooted automatically. Don’t forget to remove the USB drive and change boot medium from BIOS settings so that Proxmox VE will boot from the installed disk.

9) Access the Proxmox VE Web Interface

Open a web browser and navigate to the IP address you assigned in Step 7, followed by port 8006 (e.g., http://your_server_ip:8006).

While accessing the Web interface, we will get following screen, So Accept the Risk and Continue as we are using self-signed certificates for web interface.

Next, log in with the username “root” and the password you set in Step 6.

Click on Login, this will take us to dashboard (Web UI). You will get a warning message like “No Valid Subscription”, Choose OK to ignore the warning,

Finally, we will get the following Proxmox VE Web UI.

Great, this confirms that Proxmox VE has been installed successfully on your server.

As we don’t have valid subscription, let’s change its enterprise package repository to community repository in the following step.

10) Change Proxmox Enterprise Repository to Community

From the Web UI, Select the host (pv01) under the Datacenter and then click on console,

Now, go to directory “/etc/apt/sources.list.d/”

# cd /etc/apt/sources.list.d/

Edit ceph.list file, comment out the enterprise repo and add community repo for ceph,

# vi ceph.list

#deb https://enterprise.proxmox.com/debian/ceph-quincy bookworm enterprise
deb http://download.proxmox.com/debian/ceph-quincy bookworm no-subscription

save and close the file

Next edit the ‘pve-enterprise.list’ and comment out enterprise proxmox repo and add community repo url.

# vi pve-enterprise.list

#deb https://enterprise.proxmox.com/debian/pve bookworm pve-enterprise
deb http://download.proxmox.com/debian/pve bookworm pve-no-subscription

save and quit the file.
