Introduction This hands-on 4-day Linux System Administration course teaches attendees how to administer, configure and upgrade Linux systems running one of the three major Linux distribution families (Red Hat, SUSE, Debian/Ubuntu). Focused on enterprise environments, it provides Linux system administrators with all the ools and concepts needed to efficiently build and manage a production Linux infrastructure. This course presents state-of-the-art techniques used in the industry and applies them in the context of practical labs.

Audience profile This course is intended for System administrators and users who already have at least some basic exposure to Linux or another UNIX-based operating system constitute the target audience for this class. Anyone who is looking to acquire practical knowledge in the field of system administration in enterprise environments will save significant time by attending this course. It should also be considered a necessary step to be taken by anyone considering more advanced classes in our System Administration curriculum track. The concepts covered provide important building blocks for anyone looking to attend more advanced classes, in particular LFS311: Linux Network Management. Prerequisites Before attending this course, students must have the following technical knowledge: • Knowledge of the basic components of Linux • Familiarity with text editors (emacs, VI) • Working knowledge of Bash scripting • Attendees should already have prior exposure to a Linux or UNIX system and practical experience with the command line interface at a level that is equivalent to what is covered in our free LFS101x - Introduction to Linux course (available on edX.org) • Basic tools such as text editors, file utilities and basic tasks are assumed to be well-understood prior to this course Course Objectives After completing this course, students will be able to: • Perform essential Linux commands such as installation, searches and manipulating files • Operate running Linux systems by managing the boot process, scheduling jobs, updating the system, monitoring system performance and managing security • Manage users and groups by adding/deleting/modifying, configuring LDAP and PAM, modifying user processes and resources • Ensure network performance via configuration, monitoring, tunnelling and routing of traffic • Configure services such as DNS, shares, SSH and SELinux/AppArmor as well as servers for DHCP and HTTP • Manage system storage by using partitions, logical volumes, phsyical volumes, ACLs, quotas and clustering Course Content Module 1: Introduction After completing this module, • FHS Linux Standard This module defines the students will be able to: Directory Tree organization responsible for Linux • Describe the mission of • root (/) directory and explains how it promotes, The Linux Foundation and • /bin protects, and advances Linux. its role in the Linux and • /dev Lessons: Open Source community • /etc • Linux Foundation • Configure the system for • /home • Linux Foundation Training safe use via the sudo • /lib and /lib64 • Linux Foundation command • /media Certifications • /mnt • Laboratory Exercises, Module 2: Linux Filesystem Tree • /opt Solutions and Resources Layout • /proc • E-Learning Course: This module explains how the Linux • /sys LFS201 Filesystem is organized and points • /root • Distribution Details out the key directories and their • /sbin Lab: Module 1 Labs roles. • /tmp • Conﬁguring the System for Lessons • /usr sudo • Data Distinctions • /var • /run
