I don’t have spare peripherals like a monitor and a keyboard. How do you suggest I do a bare-metal install of Debian on a computer (meant to be a server)?
While I agree with most people here that finding a keyboard and screen would be the easiest option, you do have a couple of other options:
Use a preseed file
A preseed lets the installer run completely automatically, without user intervention. Get it to install a basic system with SSH and take it from there. You’ll want to test the install in a VM, where you can see what’s going on before letting it run on the real server. More information here: https://wiki.debian.org/DebianInstaller/Preseed
Boot from a live image with SSH
Take a look at https://wiki.debian.org/LiveCD in particular ‘Debian Live’. It looks like ssh is included, but you’d want to check the service comes up on boot. You can then SSH to the machine and install to the harddrive that way. Again, test on a VM until you know you have the image working, and know how to run the install, then write it to a USB key and boot the tsrget server from that.
This all assumes the target server has USB or CD at the top of its boot order. If it doesn’t you’ll have to change that first, either with a keyboard and screen, or via a remote management interface sych as IPMI.
Once upon a time you could use a thing called debootstrap to install Debian on the hard disk in a chroot on another machine, then switch the hdd to the target machine. Not sure if that thing is still around.
Yes, that’ll work too, it does involve adding the disk to your machine temporarily though, so just be carefully which disk you format to do it. Please don’t ask why I say that, it brings back painful memories…
I did look at Preseed and it’s probably a good idea if I’m doing many installs at once. I will still look at it but I’ll likely have to purchase a monitor anyway. It is unfortunate because I don’t have any thrift stores nearby
It’s going to be a balance between your time getting an automated approach to work and the cost/effort of getting a monitor. Getting preseed working can be a bit fiddly, but it does mean you’ve learnt a new skill, getting a monitor sounds like it’ll be a pain, and you might only need it once.
Putting a simple preseed file on a debian install image is probably going to be your best bet. Assuming you can run a VM on your current machine it shouldn’t be too difficult to test it until you’re happy with it.
Wow that’s expensive. But thanks something to keep in mind. I’m planning to build my own $25 KVM with Chinese parts off of Aliexpress and PiKVM (if that’s possible)
Connect it to your PC or laptop and do a netinstall. Configure SSHD and a static ip. Plugin the disk to your server and then connect via ssh to admin it.
You could also set your laptop or PC to boot from the attached disk in the bios to test the services you want to start are starting
Plug drive in main computer, install Debian on it along with network config and SSH access, put drive back into server and power on.
I guess technically you can also make an ISO that will just auto wipe the drive and install upon booting it but you still need a keyboard to get into the boot menu.
I made my own tiny pilot device for less than £100 and it has worked flawlessly for a few years.
This assumes your server has a hdmi output, if not you will need a VGA to hdmi or similar converter, danger of it becoming a bit of a hodge-podge of adapters, but hey, if it works, it works!
I’ve no experience with either of those devices. So long as they’re comparable in terms of USBC features (otg) to emulate the keyboard and mouse then you should be good as the overhead of running the software seems to be minimal from my usage.
Without that, you’ll get video without keyboard and mouse support.
You’ll waste more time trying to figure out how to do this than it would take to move a monitor and keyboard to the server, do the install, and plug the monitor and keyboard back into your main computer. Once the server is up, you can administer it over the network via ssh.
True, it’s just that I’d like to avoid purchasing more useless stuff. I might move in a few months and maybe carry these computers but I definitely won’t be able to take my monitor. Just going to be a waste of money, and I’m trying to be frugal.
I am planning to build a small cheap DIY KVM using PiKVM and cheap Aliexpress parts (Raxda’s Zero 3W or the Banana Pi Zero, not sure if they are supported though) in about $25 which I can probably carry around
Definitely agree for a single install. If OP has a bunch of these installs to do, then editing an install USB to configure networking and enable sshd might be worth the effort. Do the install over ssh and hope the machine starts up as desired, but even then, if it doesn’t just magically appear on the network, he’s going to need a monitor to see where the startup failed.
Raspberry Pi’s disk imager will let you pre-configure networking, accounts, and ssh, so you just write the image to an SD card, plug it in, and go. That’s a great solutions for systems usually meant to be headless and removable media. If OP’s client hardware allows, he could plug in the M2 or SATA drive meant to be the server’s startup, install Deb there, and. transfer to the server hardware. That’s definitely more work that just swapping the keyboard & monitor, but it accomplishes OP’s stated goal. (Otherwise, a lot of this thread follows the linux meme of “How do I [X]?” “[X] is dumb, do [Y] instead.”)
My reply initially had a “if you had a fleet of these things…” addendum, but OP’s post read (to me) as though he was converting commodity hardware into a makeshift home server, so I removed it because it was almost certainly not relevant.
It is possible but I wouldn’t do it. Too much effort for too little result.
Just plug your main monitor / keyboard into the server, run the setup and don’t install a DE. Afterwards login, enable SSH, unplug the monitor and do whatever you need over SSH.
Let’s face it, you’ll have to do this procedure once every xyz years, there’s no point in complicating this stuff. Also depending on your motherboard you may or may not be able to boot into the installer without a screen / keyboard attached. Another option is to install the OS in another computer and the move the hard drive to the target server - this is all fine until you run into UEFI security or another detail and it doesn’t boot your OS.
Well I see your problem, but you’re going to have a bad time without a screen. Maybe you can get something second hand / cheap or even ask a friend to borrow one for a few days?
Take out the hard drive out of your laptop and put the drive for the server in it, install Debian using the built in monitor and keyboard of your laptop.

PXE boot? It must be enable in the bios already. Then you could prep a image and deploy it that way.
I don’t think it’s enabled, but I guess I can’t check

You could just use the installer

Exactly. It’s junk after that

I’ll have to try that. Thanks!
example preseed file which I use to provision new servers (VMs)
Thank you!
A Debian preseed I guess
Buy a keyboard and monitor
No thrift stores nearby though
If OP has a thrift store nearby it’s pretty likely they can get both for under $30.
I bought a 21 inch 1080p Viewsonic monitor from a thrift store just the other day for $6. I got it just for this use case.
I had a spare for this purpose up until about a month ago when the backlight went out on one of my daily drivers.
Also, a couple of days ago I got a pretty nice steelcase apex 3 keyboard with RGB lights for $5.
If you really, really, really don’t want to buy a keyboard and monitor, you can buy a USB KVM console, but it’ll likely cost more. Something like this: https://www.startech.com/en-us/server-management/notecons01
Wow that’s expensive. But thanks something to keep in mind. I’m planning to build my own $25 KVM with Chinese parts off of Aliexpress and PiKVM (if that’s possible)
My go-to solution is to use a vm and pass it raw access to the os disk on my normal desktop. Then I just put the disk into the server.
The traditional way is to use a serial console from another device.
Can you remove the boot disk?
Yes
Connect it to your PC or laptop and do a netinstall. Configure SSHD and a static ip. Plugin the disk to your server and then connect via ssh to admin it.
You could also set your laptop or PC to boot from the attached disk in the bios to test the services you want to start are starting
deleted by creator
Planning to do that yes
Do you have a second computer running Linux? If you do install virtual manager and then pass though the disk. (LUN passthough)
Next boot the VM with the Debian installer and install. Finally shutdown the VM and plug it into the physical device.
Plug drive in main computer, install Debian on it along with network config and SSH access, put drive back into server and power on.
I guess technically you can also make an ISO that will just auto wipe the drive and install upon booting it but you still need a keyboard to get into the boot menu.
Yes that’s an option I’m looking at. Thanks
Also, the word you’re looking for is: “headless”, as in, “headless install”
Usually I want to see the BIOS settings at least once. So that’s enough reason to carry a keyboard + monitor there.
Otherwise that network boot option with a TFTP server comes to my mind. But I have never tried it on a new, empty machine.
Ipmi interface?
I use a KVM over IP.
I made my own tiny pilot device for less than £100 and it has worked flawlessly for a few years.
This assumes your server has a hdmi output, if not you will need a VGA to hdmi or similar converter, danger of it becoming a bit of a hodge-podge of adapters, but hey, if it works, it works!
I’m planning to use a Raxda Zero 3W/Banana Pi Zero for this. Do you think this will suffice? I don’t need speed or power, it just needs to be usable.
I’ve no experience with either of those devices. So long as they’re comparable in terms of USBC features (otg) to emulate the keyboard and mouse then you should be good as the overhead of running the software seems to be minimal from my usage.
Without that, you’ll get video without keyboard and mouse support.
Thanks, I’ll take a look!
There’s a bunch of other variants like PiKVM and BIiKVM as well. Even some cheap knockoffs on Aliexpress that may do the job.
You’ll waste more time trying to figure out how to do this than it would take to move a monitor and keyboard to the server, do the install, and plug the monitor and keyboard back into your main computer. Once the server is up, you can administer it over the network via ssh.

Agreed on all counts.

All I have is a laptop. I’m getting these machines for free from a friend

Take out the hard drive out of your laptop and put the drive for the server in it, install Debian using the built in monitor and keyboard of your laptop.
You’re going to want a monitor and keyboard anyway. It’s going to be pretty hard to troubleshoot a boot issue in the future without them.
yep, a tiny boot error and suddenly you need to punch commands into initramfs. good luck with that headlessly.
I picked up a second hand monitor from a goodwill shop for like $7USD. It would be worth having a display of some sort for troubleshooting.
Yeah at those price points it isn’t worth it at all to attempt a headless install.
