Для изучения возможностей современных open source программных продуктов арендовал у моего хостинг-провайдера BeGet.com виртуальный сервер под ОС Ubuntu Server. Будет доступен по адресу http://iabzalov.site - для этого купил на год второй домен, зарегистрировал в DNS через Beget. Хочу попробовать возможности Zabbix и подобные проекты. Ход работ буду отражать в этой заметке.
Начинается всё просто - арендовал сервер в режиме VPS (о том, что это такое пишет мой провайдер - VPS) по минимальному тарифу (330 руб/месяц). Аренда домена iabzalov.site также не дорогая. Регистрация домена занимает не более 5 минут. Домен SITE выбран исходя из минимальной цены, для желающих есть другие DNS-домены верхнего уровня (описаны Регистрация домена).
Что такое ОС Ubunt Server описано на сайтах ubuntu.com и ubuntu.ru. Начал изучение с этой ОС потому, что её по какой-то причине выбрал сам провайдер beget.com для установки на свои железные серверы. Причины выясняю :)
Вначале необходимо в DNS сообщить миру, что iabzalov.site = IP-адресу моего нового сервера. Делается просто, в консоли управления cp.beget.com - необходимо поправить A-запись, соответствующую домену.
Сервер пишет про себя так

Автоматическое подключение к серверу по SSH
1. Утилитой PuTTYgen сгенерируем публичный и приватный ключ
c:\ssh\iabzalov.site.ppk - приватный ключ,
c:\ssh\iabzalov.site - публичный ключ.
2. По окончании процесса генерации, утилита предоставит Вам сгенерированный приватный и публичный ключ.
Публичный, нужно занести в файл authorized_keys, который находится в папке .ssh в корне Вашего аккаунта на сервере, а приватный ключ сохраняем себе на компьютер. Для этого нажимаем на кнопку Save private key.

NAME
apt-get - APT package handling utility -- command-line interface
SYNOPSIS
apt-get [-asqdyfmubV] [-o=config_string] [-c=config_file] [-t=target_release] [-a=architecture] {update | upgrade |
dselect-upgrade | dist-upgrade | install pkg [{=pkg_version_number | /target_release}]... | remove pkg... |
purge pkg... | source pkg [{=pkg_version_number | /target_release}]... |
build-dep pkg [{=pkg_version_number | /target_release}]... |
download pkg [{=pkg_version_number | /target_release}]... | check | clean | autoclean | autoremove |
{-v | --version} | {-h | --help}}
DESCRIPTION
apt-get is the command-line tool for handling packages, and may be considered the user's "back-end" to other tools using
the APT library. Several "front-end" interfaces exist, such as aptitude(8), synaptic(8) and wajig(1).
Unless the -h, or --help option is given, one of the commands below must be present.
update
update is used to resynchronize the package index files from their sources. The indexes of available packages are
fetched from the location(s) specified in /etc/apt/sources.list. For example, when using a Debian archive, this
command retrieves and scans the Packages.gz files, so that information about new and updated packages is available.
An update should always be performed before an upgrade or dist-upgrade. Please be aware that the overall progress
meter will be incorrect as the size of the package files cannot be known in advance.
