Remote unattended installation means installation of remote server without any human interference.
Remote unattended installation means installation of remote server without any human interference.
This process is very useful for bare metal provisioning, automated installation on multiple servers, etc.  
This process is very useful for bare metal provisioning or automated installation on multiple servers.
 
I have used FAI (Fully Automatic Installation) to automate remote installation of ProxmoxVE. I have used steps from "ProxmoxVE installation over Debian wheezy". So this does not install ProxmoxVE from ProxmoxVE ISO. It installs Debian wheezy first and then ProxmoxVE.  
'''What is Proxmox?'''<br />
Proxmox is debian based OS, which provides Virtualization Platform like VMware.
https://www.proxmox.com/en/
 
'''What is FAI?'''<br />
FAI is a non-interactive system to install, customize and manage Linux systems and software configurations on computers as well as virtual machines and chroot environments, from small networks to large-scale infrastructures like clusters and cloud environments. It's a tool for unattended mass deployment of Linux.

In this example Bare Metal Provisioning of Proxmox OS is shwon. We can do with any other Linux as well.

Introduction

Remote unattended installation means installation of remote server without any human interference. This process is very useful for bare metal provisioning or automated installation on multiple servers. I have used FAI (Fully Automatic Installation) to automate remote installation of ProxmoxVE. I have used steps from "ProxmoxVE installation over Debian wheezy". So this does not install ProxmoxVE from ProxmoxVE ISO. It installs Debian wheezy first and then ProxmoxVE. FAI is a non-interactive system to install, customize and manage Linux systems and software configurations on computers as well as virtual machines and chroot environments, from small networks to large-scale infrastructures like clusters and cloud environments. It's a tool for unattended mass deployment of Linux. "FAI-Fully Automatic Installation" is used to automate headless installation of Proxmox or Debian. http://fai-project.org/

Basic Architecture

Components:
This setup has following components required.

fai-server
DHCP server
NFS Server
TFTP Server

Basic Process:

- Client machine (On which Proxmox is going to be installed.) boots from Network PXE.
- It searches for DHCP Server.
- DHCP Server on FAIserver provides Network Details to Client such as IP address, Netmask, Gateway, etc. It also points clients to TFTP & NFS server.
- TFTP trasfers the kernel to Client Machine
- NFS Server Mounts the nfsroot on Client machine
- FAI Scripts starts the installation

Important Configurations files and folders of FAI:

Configuration File/Directory Details
/etc/fai/ FAI configuration folder
/etc/fai/fai.conf FAI configuration file
/etc/fai/nfsroot.conf NFSroot configuration file
/etc/fai/apt/ FAI repositories which will be used while installation
/srv/fai/config/ FAI Client configuration space. It has scripts which will be used while installation of Client
/srv/fai/package_config/ Configurations related to Package installation
/srv/fai/disk_config/ Configurations related to disk partition layout
/srv/fai/scripts Miscellaneous scripts required for installations
/srv/fai/nfsroot NFS Root file system which will be shared by NFS and will be mounted as Root filesystem on client machine
/etc/dhcp/dhcpd.conf DHCP configuration file
/etc/exports NFS configuration file
/etc/default/tftpd-hpa TFTP configuration file
/etc/hosts Hosts declaration file / File DNS


Implementation:

Scenario:
To follow these steps require 2 machines Server & Client. Server is the one which has FAI Server configured on Debian Wheezy. Client is the one on which ProxmoxVE is going to be installed.

 Server Name: faiserver  
 Server IPAddress: 192.168.0.1/24
 Client Name: demohost
 Client IPAddress: 192.168.0.2/24


Steps:
Prepare FAI-Server:
1. Install Debian Wheezy with net-install ISO. Just install OpenSSH server nothing else on it.
2. Install Required Applications

 apt-get -y install apache2 fai-quickstart fai-doc fai-server isc-dhcp-server tftpd-hpa nfs-kernel-server syslinux-common debmirror

Create Local Debian Mirror:

 ln -s /files/scratch/debmirror /var/www/debmirror
 /usr/share/doc/fai-doc/examples/utils/mkdebmirror
 /etc/init.d/apache2 restart

Configure /etc/hosts: Add below entries:

 192.168.0.1     faiserver
 192.168.0.2     demohost

Configure /etc/fai/fai.conf: Make sure you have these entries in fai.conf

 SERVER=192.168.0.1
 FAI_CONFIG_SRC=nfs://$SERVER/srv/fai/config
 # Account for saving log files and calling fai-chboot.
 LOGUSER=fai
 FAI_LOGPROTO=ssh

Configure /etc/fai/nfsroot.conf": Make sure nfsroot.conf looks like:

 FAI_DEBOOTSTRAP="wheezy http://http.debian.net/debian"
 FAI_ROOTPW='$1$kBnWcO.E$djxB128U7dMkrltJHPf6d1'
 NFSROOT=/srv/fai/nfsroot
 TFTPROOT=/srv/tftp/fai
 NFSROOT_HOOKS=/etc/fai/nfsroot-hooks/
 FAI_DEBOOTSTRAP_OPTS="--exclude=info"
 
 # Configuration space
 FAI_CONFIGDIR=/srv/fai/config

Configure /etc/fai/apt/sources.list: sources.list should look like below:

 deb http://192.168.0.1/debmirror/debian wheezy main contrib non-free
 deb http://192.168.0.1/debmirror/debian-security wheezy/updates main contrib non-free
 
 # PVE repository provided by proxmox.com, only for installation (this repo will stay on 3.1)
 deb http://download.proxmox.com/debian wheezy pve
 
 # security updates
 deb http://security.debian.org/ wheezy/updates main contrib

Prepare fai: Run fai-setup command to prepare fai

 $ fai-setup -v


Configure /etc/dhcp/dhcpd.conf: Note down MAC address of NIC of the client machine.

 deny unknown-clients;
 option dhcp-max-message-size 2048; 
 use-host-decl-names on;
 
 subnet 192.168.0.0 netmask 255.255.255.0 {
 option routers 192.168.0.1;
 option domain-name "<domainName>";
 option domain-name-servers 8.8.8.8;
 option time-servers 192.168.0.1;
 option ntp-servers 192.168.0.1;
 server-name faiserver;
 next-server faiserver;
 filename "pxelinux.0";
 }
 
 host demohost {hardware ethernet <MAC Address>;fixed-address 192.168.0.2;}

Restart Dhcp server: Run below command to restart dhcp server. Note that I am using init script here.

 /etc/init.d/isc-dhcp-server restart

Configure /etc/exports for NFS share: fai-setup command will add required entries in /etc/exports. Still you need to do some modifications so please make sure it should look like as below:

 /srv/fai/config 192.168.0.0/24(async,ro,no_root_squash)
 /srv/fai/nfsroot 192.168.0.0/24(async,ro,no_root_squash)

Restart NFS service:

 /etc/init.d/nfs-kernel-server restart

Configure TFTP Server: Config file /etc/default/tftpd-hpa should look like below.

 TFTP_USERNAME="tftp"
 TFTP_DIRECTORY="/srv/tftp/fai"
 TFTP_ADDRESS="0.0.0.0:69"
 TFTP_OPTIONS="--secure"

Create directory for tftp:

 mkdir -p /srv/tftp/fai/pxelinux.cfg

Copy pxelinux.0, kernel and initrd to tftp root:

 cp /boot/vmlinuz-3.2.0-4-amd64 /srv/tftp/fai/
 cp /usr/lib/syslinux/pxelinux.0 /srv/tftp/fai/
 cp /boot/initrd.img-3.2.0-4-amd64 /srv/tftp/fai/

Copy fai.conf inside nfsroot

 cp /etc/fai/fai.conf /srv/fai/nfsroot/etc/fai/

Add to /srv/fai/nfsroot/etc/ssh/ssh_config

 StrictHostKeyChecking no

Make sure /srv/fai/nfsroot/etc/hosts have below entry:

 192.168.0.1 faiserver

Initialize Bootloader config for demohost (client)

 fai-chboot -IB demohost

Above command will create config file under /srv/tftp/fai/pxelinux.cfg/ File Name will be something like: C0A87A64 Just edit that file and make sure it should look like below:

 default fai-generated
 label fai-generated
 kernel vmlinuz-3.2.0-4-amd64
 append initrd=initrd.img-3.2.0-4-amd64 ip=dhcp root=/dev/nfs nfsroot=192.168.0.1:/srv/fai/nfsroot:vers=3 aufs FAI_FLAGS=verbose,sshd,reboot FAI_ACTION=install


Now reboot client machine from Network PXE boot. It will get automatically Proxmox installed.
