目录
Caveat
As you may already have guessed following this instruction may break your system and you are on your own to fix it again.
Scenario
This instruction describes how to install Ubuntu on a dedicated server over ssh. I assume that your provider provides you with a rescue system from which you can boot and prepare your system. An Online replacement is possible, but it is some more work and a lot more risky if things go bad (the basic idea is to temporarily disable your swap and install a transitional system on it).
Preparing the Hard Disk
Partitioning
Use fdisk to partition your hard disk.
Remember to set the root partition bootable!
For the rest of this instruction we assume the following partition layout.
/dev/hda1 (83 Linux) - for /, /dev/hda2 (82 Linux swap) - as swap
Creating File Systems
Below is how we get our / populated with ext3.
And the same for our swap partition.
The Base System
Mounting Root
Getting Debootstrap
Debootstrap is a collection of scripts that we will use in the next step to set up a base system. We need an appropriate version of debootstrap from http://archive.ubuntu.com/ubuntu/pool/main/d/debootstrap/ to make this work.
Make sure that binutils is installed on your system.
On an apt based system we can use dpkg to install it.
If your current system is rpm based, use alien to install it or find a rpm on the web (http://azhrarn.underhanded.org/debootstrap-0.2.23-1.i386.rpm).
If your system is neither, this might work.
Installing the Base System
(arch may be different for you, e.g. md64, hppa, ia64, powerpc, or sparc)
Basic Configuration
Set the Hostname
Change HOSTNAME to whatever suits your environment.
fstab
Put the following in fstab:
proc /proc proc defaults 0 0 /dev/hda1 / ext3 defaults,errors=remount-ro 0 1 /dev/hda2 none swap sw 0 0
Networking
Make sure to use your network details instead.
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 10.0.0.10
network 10.0.0.0
braodcast 10.0.0.255
gateway 10.0.0.1
netmask 255.255.255.0
Make sure to use your hostname and domain.
127.0.0.1 localhost 127.0.0.1 hostname.domain.tld hostname
You need a valid resolv.conf with at least one valid nameserver, e.g.:
nameserver 10.0.0.1
Enter the new environment
Before we chroot into the new environment we need to mount /proc and /dev
mount -t proc none /mnt/ubuntu/proc mount -o bind /dev /mnt/ubuntu/dev LANG= chroot /mnt/ubuntu /bin/bash
Change the root password
It is just bad if you forget this, so just ....
Create a user and switch shadow password on
Installing Packages
Installing OpenSSH Server
Install a Kernel
Choose the right kernel for your architecture. I go with:
Installing GRUB
The boot loader is most important, so do:
apt-get install grub mkdir /boot/grub cp /lib/grub/i386-pc/* /boot/grub vim /boot/grub/grub.conf
default 0 timeout 3 title=Ubuntu root (hd0,0) kernel /vmlinuz root=/dev/hda1 initrd /initrd.img
ln -s /boot/grub/grub.conf /boot/grub/menu.lst
grub> root (hd0,0) grub> setup (hd0) grub> quit
Reboot
Finishing
After the reboot ssh in again.
Generate locales
Istall some more packages
apt-get install ubuntu-standard

- The Gentoo Handbook contains a very good (Gentoo specific) instruction on chrooted installation procedures.
- An other instruction from the Ubuntu Installation Guide is somewhat outdated and has shortcomings related to the bootloader installation.
