INSTALLING LINUX / LIVE LINUX / VIRTUALIZATION

Content under development.

Main Objectives of this Practice Tutorial

  • Download and install the VirtualBox VM software application
  • Download and run the Knoppix Live VirtualBox file in a virtual machine
  • Open a terminal and connect to your Matrix account via the ssh utility
  • Run several open-source applications in your graphical Knoppix Linux environment
  • Understand the limitation of running Knoppix Live as opposed to a persistent Knoppix installation

KEY CONCEPTS

Installing Linux

Having a Linux system on your home computer provides access to a large selection of open source software.

Installing your own version of Linux on your notebook or desktop computer also can make it easier to practice working
in the Linux environment and learn how to perform routine Linux OS administration tasks.


Listing of Common Linux Distributions.
(Image licensed under cc)

A Linux distribution (often abbreviated as distro) is an operating system made from a software collection that is based upon the Linux kernel and, often, a package management system. Linux users usually obtain their operating system by downloading one of the Linux distributions, which are available for a wide variety of systems...

Reference: https://en.wikipedia.org/wiki/Linux_distribution


Steps in the Linux Installation Process:

  • Select a Linux Distribution to download (ISO image file or VM file).
  • Create VM and install Linux Distribution or run VM file.


Linux Installation Methods

Standalone Installation

Linux is the only OS on the computer.
Any existing data on your hard disk will be erased.

Dual-boot / Multi-boot Installation

A boot menu allows the user to select the desired OS.

Advantages of Dual-Boot or Multi-Boot:
  1. This option provides a method to access your computer if one OS fails to boot-up.
  2. Access the Windows partition if your Windows OS cannot boot-up.
  3. This booting method is great for troubleshooting
    (for example: boot into Linux OS to eliminate a hardware issue).
Installation Tips:
  1. It is recommended to back up important data before proceeding.
  2. It is recommended to install the Linux OS last, as other operating systems may not offer a multi-boot option.


Virtual Machine Installation

Virtualization is the process of running a virtual instance of a computer system in a layer abstracted from the actual hardware. Reference: https://opensource.com/resources/virtualization
The virtualized OS is installed and run in a window under another OS. Special software is used to manage the entire process, referred to as the hypervisor.

Advantages of Virtualization:
  1. You can run VM from an ISO image file or a VM file.
  2. One or more virtual machines can be run at the same time.
  3. The guest OS shares hardware with the host OS and possibly other virtualized systems.
  4. The guest systems have network access through the host.
Installation Tips:
  1. Virtualization requires a compatible processor: not all processors support that feature.
  2. Your BIOS should be set to enable Virtualization.
  3. Popular VM software for Windows, Apple and Linux OS include:
    • VMware
    • Oracle Virtual Box


Live Linux CD

A live CD (also live DVD, live disc, or live operating system) is a complete bootable computer installation including operating system which runs directly from a CD-ROM or similar storage device into a computer's memory, rather than loading from a hard disk drive. A Live CD allows users to run an operating system for any purpose without installing it or making any changes to the computer's configuration. You can also create a Live USB, which depending on the configuration and USB size may also allow saving data back to the USB (unlike a Live CD/DVD).

INVESTIGATION 1: CREATING A RED HAT ACCOUNT AND DOWNLOADING THE ISO

ATTENTION: The due date for successfully completing this tutorial (i.e. tutorial 1) is by Friday, December 15 @ 11:59 PM (Week 14).

In this investigation, you will first create a Red Hat account and download the install medium (ISO). This is required to install Red Hat as a virtual machine in INVESTIGATION 2. Be sure to remember your login and password.

Perform the Following Steps

Registering for a Red Hat account.

  • On the top right side, click Login and select Register Now. You should see the following screen.
