Linux System Administration

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 tools 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.

Target audience:
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.

Prerequisities:

  • 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. Basic tools such as text editors, file utilities and basic tasks are assumed to be well-understood prior to this course.

Program:

  • Module 1: Introduction
    • This module defines the organization responsible for Linux and explains how it promotes, protects, and advances Linux.
  • Module 2: Linux Filesystem Tree Layout
    • This module explains how the Linux Filesystem is organized and points out the key directories and their roles.
  • Module 3: Processes
    • This module explains how to work with Linux processes. It begins with an overview of what processes are and how they work before proceeding to illustrate how to create, monitor, prioritize and limit processes.
  • Module 4: Package Management Systems
    • This module explains how to work with the major package management systems used in Linux distributions. Covers both RPM and DKPG as well as the use of version control systems such as git.
  • Module 5: Package Installers
    • This module explains how to use the major package installers, including yum, zypper and APT. It also explains the role that package installers play in automating software management and dealing with dependencies.
  • Module 6: System Monitoring
    • This module explains how to monitor your Linux system and use tools to test it and report any issues.
  • Module 7: Linux Filesystems
    • This module explains how to work with Linux Filesystems, starting with the understanding that Linux treats everything as a file. IT covers Virtual filesystem (VFS), Filesystem Usage and Attributes, Major types (ext4, XFS, btrfs) and how to create, format, mount, swap and repair Filesystems.
  • Module 8: Partitioning and Formatting Disks
    • This module explains how to work with disks in Linux by naming, partitioning and sizing them.
  • Module 9: More on Linux Filesystems
    • This module expands on Module 8. It explains how to create, format, mount and check filesystems.
  • Module 10: Encrypting Disks
    • This module explains how to protect filesystems from prying eyes and protect the data they contain.
  • Module 11: LVM and RAID
    • This module explains how to work with RAID and Logical Volume Management (LVM).
  • Module 12: Kernel Services and Configuration
    • This module explains how the Linux Kernel is configured, how the modules and utilities work, the function of sysctl and udev and Device Management.
  • Module 13: Virtualization Overview
    • This module explains Virtualization, gives a brief history, and shows how to create and install a virtual machine.
  • Module 14: Containers Overview
    • This module explains the basics of what a container is, what application virtualization is, and Docker as an example of container technology.
  • Module 15: User and Group Account Management
    • This module explains how to work with users and groups in Linux. It also covers how to work with passwords, restricted shells, the root account, Pluggable Authentication Modules (PAM), LDAP and SSH.
  • Module 16: Networking
    • This module explains how to conduct basic networking in Linux. It covers IP addresses, Hostnames, Network Interfaces, Routing and Name Resolution.
  • Module 17: Firewalls
    • This module explains how to work with firewalls in Linux. It covers both command line tools and GUI tools as well as firewalld. Zones and source management are discussed, as is service and port management.
  • Module 18: System Startup and Shutdown
    • This module explains how to manage startup and shutdown processes in Linux.
  • Module 19: Backup and Recovery Methods
    • This module explains how to backup data in Linux. It covers the tools that are used for backup and compression as well as for moving and copying files and also for restoring files.
  • Module 20: Linux Security Modules
    • This module explains how the Linux kernel enhances security through the use of the Linux Security Modules framework, particularly with the deployment of SELinux.
  • Module 21: Local System Security
    • This module explains how to secure systems against both internal and external threats. It covers how to identify risks and provides guidance on how to decide what protection is appropriate. Finally, it covers the basic types of security available (physical, filesystem, and security modules e.g. SELinux).
  • Module 22: Basic Troubleshooting and System Rescue
    • This module explains how to conduct troubleshooting in Linux as well as likely sources of issues. It covers basic concepts in system rescue and recovery and how to identify corrupted filesystems.
