Proxmox VE unattend install

Note

we can find proxmox-installer source on https://git.proxmox.com/?p=pve-installer.git;a=blob;f=proxinstall;h=f9b67a37e042ed7503238e8cf4c2dd19e1ae5de8;hb=refs/heads/master

We can find this in proxmox-ve.iso

• debian-base-rootfs -->pve-base.squ

• pve-installer -->pve-base.squ

I add a start.sh to .xinitrc(pve-installer).

root@jammy:~/2/proxmox/packages# cat /tmp/iso/squashfs-root/.xinitrc 
/usr/bin/xrdb -load /.Xdefaults
/usr/bin/X11/xsetroot -solid grey
bash /start.sh
openbox &
/.spice-vdagent.sh &
G_SLICE=always-malloc /usr/bin/proxinstall

start.sh will executes install-pve.sh file which in /cdrom .

Now, We can edit install-pve.sh if we want to do more.

files

• geniso.sh ->modify iso
• install_pve_to_rootfs-for-pve-base.sh ->old scripts
• install-pve.sh ->install pve to disk shell scripts
• sart.sh ->add to .xinitrc
• rootfs.sh -> diy rootfs
• msg.conf -> conffile

How to use

1. Use UltraISO to modify iso

2. Create cluster server's config -->msg.conf

Don't more or less

root@Devops:~# cat /tmp/msg.conf
#this is config file
#mac hostname dn  ip_addr cidr  gateway install_way time_zone passwd  pvedisk
EA:5A:F0:5A:B3:D2 pve2 bingsin.com 10.13.14.22 24  10.13.14.252 cdrom Asia/Shanghai P@SSword /dev/sda

install_way --> apt|cdrom

3. Choose load conf way.

3.1. Config file with http --> modify install-pve.sh

#how to load config_file from http or cdrom (whitch is use local conf-file)
#you must set http_conf_url if you want't use http.
config_file="http"            --< set http
http_conf_url="http://192.168.3.120:801/msg.conf"

replace install-pve.sh in iso with your install-pve.sh

and push msg.conf to your webserver wwwroot

3.2. Config file with cdrom --> modify install-pve.sh

#how to load config_file from http or cdrom (whitch is use local conf-file)
#you must set http_conf_url if you want't use http.
config_file="cdrom"           --< set cdrom
#http_conf_url="http://192.168.3.120:801/msg.conf"

replace install-pve.sh in iso with your install-pve.sh

and add msg.conf to your iso root

3.3. Config file with local --> modify install-pve.sh

• local env from scripts, need config it first

#how to load config_file from http or cdrom (whitch is use local conf-file)
#you must set http_conf_url if you want't use http.
config_file="local"           --< set local
#http_conf_url="http://192.168.3.120:801/msg.conf"

edit local_config function

local_config(){
rootdisk="/dev/nvme0n1" ---> set your disk which is going to install
userpw="P@SSw0rd"
ipaddr="192.168.3.41"
netmask="24"
gateway="192.168.3.1"
eth="enp6s18"
fq="pve"
dn="bingsin.com"
}

replace install-pve.sh in iso with your install-pve.sh

3.4. Config file with rand --> modify install-pve.sh

• Use DHCP to obtain the NIC name and IP
• Generate hostname randomly

#how to load config_file from http or cdrom (whitch is use local conf-file)
#you must set http_conf_url if you want't use http.
config_file="rand"           --< set local
#http_conf_url="http://192.168.3.120:801/msg.conf"

edit rand_config function

rand_config(){
	echo > /tmp/nets
	echo > /tmp/ips
	for nets in `ls /sys/class/net/|grep -v lo`;do
	echo "$nets" `ip addr show dev $nets |grep -v inet6|grep inet|head -n 1|awk '{print $2}'` >>/tmp/ips;
	done
	eth=`grep / /tmp/ips |head -n 1 |awk '{print $1}'`
	ipaddr=`grep / /tmp/ips |head -n 1 |awk '{print $2}'|cut -d "/" -f1`
	netmask=`grep / /tmp/ips |head -n 1 |awk '{print $2}'|cut -d "/" -f2`
	gateway=                     --> if has different ip range,We suggest  set gateway to null
	dn="bingsin.com"
	fq=`strings /dev/urandom |tr -dc a-z | head -c14`
	userpw="P@SSw0rd"  
	rootdisk=""                  ---> set your disk which is going to install
}

replace install-pve.sh in iso with your install-pve.sh

4. Save your iso and use pxe-iso-2-pxe
