It took some time as i had to find a moment to translate my notes.
I did my best with formatting but for some reason new paragraphs aren't a thing i can get working in an untiered list in a lemmy comment 🤷
I presume some basic knowledge of linux and how to install an OS on a machine, but i've tried to add every single step with commands.
If anybody knows an easier way or have any comments regarding this, feel free to educate me.
Here is the way i installed it:
Switching the kernel:
- Install default debian bookworm without desktop environment, but with “standard systems utilities” and “ssh server”
- Don't forget to LUKS it, or else you could have just used the proxmox iso 😉
- SSH server could probably be omitted if everything is done directly on the machine, but i wanted it so i could copy/paste commands
- Boot and log in as root
- Check /etc/hosts and change the ip in front of the hostname to the static ip of the machine
- Check with
hostname --ip-address, it should return the ip-address - Add proxmox repo with
echo "deb [arch=amd64] http://download.proxmox.com/debian/pve bookworm pve-no-subscription" > /etc/apt/sources.list.d/pve-install-repo.list - Add proxmox key with
wget https://enterprise.proxmox.com/debian/proxmox-release-bookworm.gpg -O /etc/apt/trusted.gpg.d/proxmox-release-bookworm.gpg - Run
apt update && apt full-upgrade - Install proxmox kernel with
apt install proxmox-default-kernel - Restart with
systemctl reboot - NOTE: The machine will boot and get stuck on loading initial ramdisk, type in the LUKS key and press enter despite not getting a prompt
Installing the packages
- Install Proxmox packages with
apt install proxmox-ve postfix open-iscsi chrony- Postfix needs to be configured, if no mailserver choose local only and let system name stay as default
- Remove debian kernel with
apt remove linux-image-amd64 'linux-image-6.1 - Update and check grub config with
update-grub- Seems redundant, because i think it does this by it self when running the command above
- If proxmox is the only OS, remove os-proper with
apt remove os-prober- This gave me an error about it not being empty, but it fixed itselv after a reboot
- I think a reboot is needed here, but i honestly don't remember. If in doubt run
systemctl reboot
Adding SSH access for root user
It's easier to copy/paste commands, this requires SSH access to the server
This can be done at any point. I did it as soon as i installed debian, and then removed it as i booted into proxmox
- Edit /etc/ssh/sshd_config with
nano /etc/ssh/sshd_config - Around line 32 find #PermitRootLogin without-password and make en new line below it and write
PermitRootLogin yes.- The commented line can be edited but i find it easier to add the line as it needs to be removed again later
- Restart the SSH server with
/etc/init.d/ssh restart - When done with copy/pasting the commands it's better to remove root SSH access again, this is done by removing the line that was added above
Removing debian user
This removes the user that was made as part of installing debian. It can probably be used, but i found it better to add all needed users once i got in to proxmox instead the [username] of course needs to be changed out for the username you used when you installed debian.
- Log in to the terminal as root
- Find the list of users with
grep ‘users’ /etc/group - Use
deluser [username]to remove the user
I'm happy to help.
Good luck with proxmox and selfhosting.
