Before I do anything on Proxmox, I do this first...
After setting up my Proxmox servers, there are a few things I do before I use them for their intended purpose.This ranges from updates, to storage, to networking and VLANS, to uploading ISOs, to clustering, and more.Join me as we pick up where the rest of the proxmox tutorials stop, and that’s everything you need to do to make these production ready (and maybe a bonus item too).

Cloning
These are the commands I run after cloning a Linux machine so that it resets all information for the machine it was cloned from.
(Note: If you use cloud-init-aware OS images as described under Cloud-Init Support on https://pve.proxmox.com/pve-docs/chapter-qm.html, these steps won’t be necessary!)
change hostname
1
sudo nano /etc/hostname
- find your hostname and change it
change hosts file
- find your hostname and change it
1
sudo nano /etc/hosts
reset machine ID

3
rm -f /etc/machine-id /var/lib/dbus/machine-id
dbus-uuidgen --ensure=/etc/machine-id
dbus-uuidgen --ensure
regenerate ssh keys

regen ssh keys
sudo rm /etc/ssh/ssh_host_*
sudo dpkg-reconfigure openssh-server

Alerts
I’ve added yet another item to my list when setting up a new Proxmox server, and that’s setting up alerts!
