How to install Ubuntu on a dedicated server via SSH

Warning: As you may have guessed, the approach described here may cause your system to fail to boot and you have to rely on yourself to fix it. Apt Install linux-image-686

This guide describes how to install http://www.aliyun.com/zixun/aggregation/13835.html ">ubuntu" on a dedicated server via SSH. I assume that your supplier provides you with a standby (or recovery or first aid) system that can guide and prepare your normal operating system; In this way, the online "system replacement" is possible, but it takes a lot of risk and is prepared to do a lot of remedial work in case things get worse (the basic Idea are to temporarily disable your swap and install a transitional system on it).

Preparing disks

Creating partitions

Use Fdisk to create partitions on disk.

# Fdisk/dev/hda

Remember to set the root partition as the active partition (which can be started)! In a later introduction, I will assume that you use the following zoning layout, depending on your situation.

/DEV/HDA1 (Linux)-for/,
/dev/hda2 (with Linux swap)-as swap

Creating a file system

Below I will format my/partition using the popular EXT3 format

# mke2fs-j/DEV/HDA1
Or
# MKFS.EXT3/DEV/HDA1

Initialize and enable our swap partition with the following command

# Mkswap/dev/hda2
# sync; Sync; Sync
# Swapon/dev/hda2

Basic system

Mount Root Partition

# Mkdir/mnt/ubuntu
# mount-t Ext3/dev/hda1/mnt/ubuntu

Get Debootstrap

Debootstrap is a set of scripts to be used in the next steps to build a "basic system". We need to get a suitable version of Debootstrap from http://archive.ubuntu.com/ubuntu/pool/main/d/debootstrap/(the nearest mirror also). First make sure that your standby system has binutils (including basic command-line tools, such as wget) tools. On a system based on APT, we can install it using dpkg.

# wget Http://archive.ubuntu.com/ubuntu/pool/main/d/debootstrap/debootstrap_0.3.3.0ubuntu2_all.deb
# dpkg-i Debootstrap_0.3.3.0ubuntu2_all.deb

If your current system is based on RPM, install it using the Alien tool or you can find its RPM version on this site (e.g., http://azhrarn.underhanded.org/debootstrap-0.2.23-1.i386.rpm). If your system does not belong to any of the above, the following commands may be useful:

# mkdir/work; Cd/work
# wget Http://archive.ubuntu.com/ubuntu/pool/main/d/debootstrap/debootstrap_0.3.3.0ubuntu2_all.deb
# AR-XF Debootstrap-udeb_0.3.3.0ubuntu7_i386.udeb
# CD/
# tar ZXVF work/data.tar.gz

Install the basic system

#/usr/sbin/debootstrap--arch i386 Dapper/mnt/ubuntu Http://archive.ubuntu.com/ubuntu

(Your arch may be different, for example: Md64, Hppa, IA64, PowerPC, or SPARC)
