Системное администрирование Linux (GL250)
Программа обучения HPE по администрированию Linux уникальна своей нейтральностью по отношению к выбору дистрибутива. Лекции общие для всех семейств Linux, а на практические занятия инструктор выбирает оптимальный дистрибутив, исходя из потребностей группы: Red Hat, SUSE или Fedora Core.
Если вы наметили в дальнейшем развиваться и как специалист по UNIX, то логично будет начать с основ этой операционной среды (например, пройдя курс U8583S (GL120)). И уже после такой предварительной подготовки (дополненной практическими действиями по установке системы) можно будет смело приступать к циклу тренингов по LINUX в области администрирования систем и сетей.
Первая часть курса (H7091S) предоставляет базовые знания, необходимые для установки, развёртывания и настройки основных сетевых служб Linux. Они включают базовые знания по установке, администрированию, настройке X-Window, настройке ядра и менеджеру логических разделов дисковой подсистемы (LVM) и RAID, основам безопасности и базовым навыкам поиска неисправностей.
Цели курса
- установка и настройка;
- процесс загрузки;
- администрирование пользователей и групп;
- администрирование файловой системы, включая квоты, FACL, RAID и LVM;
- автоматизация задач;
- клиентские сети;
- SELinux;
- управление программным обеспечением;
- лог-файлы;
- устранение проблем;
и больше.
Для кого предназначен:
Курс будет интересен всем, кто заинтересован в изучении администрирования Linux и имеет некоторый навык использования Linux или UNIX. Опытным системным администраторам окажет несомненную помощь в подготовке к Linux-сертификации.
Предварительная подготовка:
Начальные знания в области LINUX/UNIX систем, предполагается опыт практической работы с такими системами.
GL250 — Enterprise Linux System Administration
The GL250 is an in-depth course that explores installation, configuration and maintenance of Linux systems. The course focuses on issues universal to every workstation and server. Like all Guru Labs courses, the course material is designed to provide extensive hands-on experience. Topics include: installation and configuration; the boot process; user and group administration; filesystem administration, including quotas, FACLs, RAID and LVM; task automation; client networking; SELinux; software management; log files; troubleshooting; and more.
Students should already be comfortable working in a Linux or Unix environment. Fundamentals such as the Linux filesystem, process management, and how to edit files will not be covered in class. An understanding of network concepts, and the TCP/IP protocol suite is helpful. These skills are taught in the GL120 «Linux Fundamentals» course.
