Linux Administration

This course discusses the system administrative functions endemic to the Linux Operating System. 

About the Course

This course aims to give its learners the technical know-how needed to effectively conduct and manage the operations within the system namely its maintenance, enhancement, creation of user accounts and reportage, and the usage of Linux tools and its command-line interface tools.

Who this Course is for?

This course was created for individuals and professionals wanting to specialize in Linux Development and had already gone through preliminary training in the Linux OS course.

Prerequisites

As with the previous course, the individuals and professionals wanting to take this program need not hold any special certifications save for the Linux OS course which introduces the learner to the basic features of the OS from a developer's standpoint. The following credentials still hold efficacy for this particular course:

- A Bachelor's Degree in Computer Science or any related field

- A working knowledge of the Linux Operating System (from a developer's point of view)

- An experience in working on application development projects

- A familiarity with coding languages namely C and Python

Linux Administration Overview

Part 1 of 7: Get Started

This lesson serves as an introductory discussion of the system administrative functions that Linux Developers need to have a grasp of before diving into actual development.

Part 2 of 7: Basic Command Line

This lesson details the most pertinent basic command lines in the Linux system that a Linux Developer must know. This includes curl, Is, tail, cat, grep, and ps, just to mention a few.

Part 3 of 7: Files and Input Output

This lesson details how a developer should go about conducting File Management in Linux. This lesson discusses how Linux chooses to employ only a single hierarchical structure for its directory. The learners would be made to understand that this file system, simply called, "hierarchical structure" is managed not by the operating system, but by the programs themselves which are called "program directories".

This lesson also discusses the basics of how Linux Input/Output (I/O) Redirection works. This lesson informs its learners that this feature gives users the capability of redirecting the input and output of commands from and to files. This also includes the joining of multiple commands through the use of pipes that form the "command pipeline".

Part 4 of 7: Linux Shell

This lesson informs its learners of what the Linux Shell is and its function. 

The discussion defines the Linux Shell as the Linux Comand Line interpreter. The learners would be made to understand that this function provides the interface for the user to use the kernel and execute commands.

Part 5 of 7: Boot Process

This lesson details the six (6) distinct stages in a typical booting process. The following would be discussed at length: BIOS, MBR, GRUB, kernel, Init, and Runlevel programs.

Part 6 of 7: Volumes and Users

This lesson explains how Volume Management is administered through Linux. The discussion goes on to discuss what is called, "Logical Volume Management", or simply, LVM. It is defined here as a method used by Linux users to effectively manage the storage volumes for all types of physical hard disks. The lesson makes the distinction between the LVM and RAID, while bearing similarities in concept.

This lesson also discusses the three (3) types of users in Linux namely, the "Superuser" or "Root User", "System User", and "Normal User". The lesson specifies the differences across each.

Part 7 of 7: Troubleshooting

This lesson discusses general troubleshooting in Linux Administration. The discussion includes how to resolve application problems, login issues, and other server-related issues.
