README.md

Introduction

This tutorial will help you install Proxmox 5 on a freshly installed Debian 9.
It was tested on a dedicated server at hetzner.

Installation

Fisrt things first. Create a custom repository to pickup Proxmox related packages:

echo "deb http://download.proxmox.com/debian/pve stretch pve-no-subscription" > /etc/apt/sources.list.d/pve-install-repo.list
wget http://download.proxmox.com/debian/proxmox-ve-release-5.x.gpg -O /etc/apt/trusted.gpg.d/proxmox-ve-release-5.x.gpg

Update the list of the available packages and update them:

apt update -y
apt dist-upgrade -y

Install the neccessary packages for Proxmox 5 and delete obsolete:

apt install proxmox-ve postfix open-iscsi -y
apt remove os-prober -y

Update Debian kernel and grub for it to be able to reboot OS properly:

apt remove linux-image-amd64 linux-image-4.9.0-3-amd64 -y
update-grub

Completly remove and disable the rcpbind service that is often used as a vulnerability:

apt-get remove rpcbind
iptables -A INPUT -p udp -s 192.168.0.0/24 --dport 111 -j ACCEPT
iptables -A INPUT -p udp -s 127.0.0.1 --dport 111 -j ACCEPT
iptables -A INPUT -p udp --dport 111 -j DROP
echo -e "rpcbind: ALL" >> /etc/hosts.deny
systemctl disable rpcbind.service
service rpcbind stop

Reboot your server for it to abe able to pickup new kernel with Proxmox support:

reboot

After that you can download your .iso files to the /var/lib/vz/template/iso folder where Proxmox will be able to pickup them.
