[TUTORIAL] [DHCP] Single node install ONLY (no static reservation necessary)

[esi_y]

This is a specialised case of Cluster deployment tutorial on the same matter. It does NOT require DHCP static reservations and does NOT rely on DNS resolution. It is therefore easily feasible in a typical homelab setup.

DISCLAIMER DO NOT use this setup for clusters.

1. Perform regular ISO installation [1] - use a temporary static IP for the first boot, use hostname you would like to retain (pvehost in this example).

2. Install Avahi [2] daemon: apt -y update; apt install avahi-daemon

3. Remove superfluous static entry in /etc/hosts, e.g. remove 192.168.1.101 pvehost.internal pvehost line completely:

Spoiler: /etc/hosts

127.0.0.1 localhost.localdomain localhost

# The following lines are desirable for IPv6 capable hosts

::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

4. Change from static to dhcp and remove address and gateway specified in /etc/network/interfaces - example (if default install):

Spoiler: /etc/network/interfaces

auto lo
iface lo inet loopback

iface enp1s0 inet manual

auto vmbr0
iface vmbr0 inet dhcp
    bridge-ports enp1s0
    bridge-stp off
    bridge-fd 0

5. Reboot.



You may wish to check if everything is alright with journalctl -eu pve-cluster.service - it should contain a line such as (with NO errors):

pvehost pmxcfs[706]: [main] notice: resolved node name 'pvehost' to '192.168.1.101' for default node IP address

You may also want to check simply hostname --ip-address does NOT return 127.*.*.* address.

And that's about it. Also, if you are on the same subnet, you may now access your node GUI at: https://pvehost.local:8006/
