Подготовка к установке

Эта секция разъясняет некоторые аспекты, которые стоит рассмотреть перед установкой.

Ubuntu 12.04 LTS Server Edition поддерживает три (3) основных архитектуры: Intel x86, AMD64 and ARM. Ниже таблица показывает рекомендованные параметры оборудования. В зависимости от ваших потребностей вы можете снизить эти требования, однако большинство пользователей рискует разочароваться, если проигнорирует данные рекомендации.

Рекомендуемые минимальные требования:

Server Edition представляет собой базу для всех видов серверных приложений. Минималистичный дизайн представляет основу для необходимых сервисов, таких как файловый сервис, сервис печати, web сервис, постовый сервис и пр.

Требования для UEC (облачный сервер Ubuntu) немного другие; для требований Front End систем смотрите Front End Requirements, а для требований UEC узла смотрите Node Requirements.

There are a few differences between the Ubuntu Server Edition and the Ubuntu Desktop Edition. It should be noted that both editions use the same apt repositories, making it just as easy to install a server application on the Desktop Edition as it is on the Server Edition.

The differences between the two editions are the lack of an X window environment in the Server Edition, the installation process, and different Kernel options.

Kernel Differences:

Ubuntu version 10.10 and prior, actually had different kernels for the server and desktop editions. Ubuntu no longer has separate -server and -generic kernel flavors. These have been merged into a single -generic kernel flavor to help reduce the maintenance burden over the life of the release.

When running a 64-bit version of Ubuntu on 64-bit processors you are not limited by memory addressing space.

To see all kernel configuration options you can look through /boot/config-3.2.0-server. Also, Linux Kernel in a Nutshell is a great resource on the options available.

  Before installing Ubuntu Server Edition you should make sure all data on the system is backed up. See Backups for backup options.

  If this is not the first time an operating system has been installed on your computer, it is likely you will need to re-partition your disk to make room for Ubuntu.

  Any time you partition your disk, you should be prepared to lose everything on the disk should you make a mistake or something goes wrong during partitioning. The programs used in installation are quite reliable, most have seen years of use, but they also perform destructive actions.
