How to install Proxmox


  • A physical or dedicated server.
  • 64bit CPU.
  • At least 1GB of RAM (and additional RAM needed for guests).
  • A USB stick with at least 1GB.

Step 1: Download Proxmox ISO Image

The first step is to download the Proxmox VE ISO image.

1. Navigate to the official Proxmox Downloads page and select Proxmox Virtual Environment.

2. This takes you to the Proxmox Virtual Environment Archive that stores ISO images and official documentation. Select ISO Images to continue.

3. At the time of writing, the latest version of the Proxmox VE ISO Installer is 7.1. If a newer version is available, it is listed at the top. Click Download and save the file.

Step 2: Create a Bootable media

Make Bootable USB Drive from the downloaded image. See –

Step 3: Start the installation

1. Move to the server (machine) where you want to install Proxmox and plug in the USB device.

2. While the server is booting up, access the boot menu by pressing the required keyboard key(s). Most commonly, they are either EscF2F10F11, or F12.

3. Select the installation medium with the Proxmox ISO image and boot from it.

4. Next, the Proxmox VE menu appears. Select Install Proxmox VE to start the standard installation.

5. Read and accept the EULA to continue.

6. Choose the target hard disk where you want to install Proxmox. Click Options to specify additional parameters, such as the filesystem. By default, it is set to ext4.

7. Then, set the location, time zone, and keyboard layout. The installer autodetects most of these configurations.

8. Create a strong password for your admin credentials, retype the password to confirm, and type in an email address for system administrator notifications.

9. The final step in installing Proxmox is setting up the network configuration. Select the management interface, a hostname for the server, an available IP address, the default gateway, and a DNS server. During the installation process, use either an UPv4 address.

10. The installer summarizes the selected options. After confirming everything is in order, press Install.

11. After the installation is complete, remove the USB drive and reboot the system.

Step 4: Run Proxmox

1. Once the installation is completed and the system rebooted itself, the Proxmox GRUB menu loads. Select Proxmox Virtual Environment GNU/Linux and press Enter.

2. Next, the Proxmox VE welcome message appears. It includes an IP address which loads Proxmox. Navigate to that IP address in a web browser of your choice.

3. After navigating to the required IP address, you will most likely see a warning message that the page is unsafe because Proxmox VE uses self-signed SSL certificates. Select to proceed to the Proxmox web management interface.

4. To access the interface, log in as root and provide the password set when installing Proxmox.

5. A dialogue box pops up saying there is no valid subscription for the server. Proxmox offers an add-on service you can subscribe to, which is optional. To ignore the message, click OK.

Step 5: Increase usable Storage

By default the storage is devided by local – the usable storage and local-lvm – which is not usable so its good practice to delete local-lvm and add all storage to local :

After that , execute these 3 commands (confirm with Y where its needed) After the execution full storage size will be locateed in local

lvremove /dev/pve/data
lvresize -l +100%FREE /dev/pve/root
resize2fs /dev/mapper/pve-root
