LINUX RED HAT

Summary• Research for the Power Point presentation revealed that

Linux is a free operating system that has been compared to and even rated better and faster than the Windows operating system. Additionally, Linux is very popular with software developers because of the many programming language compilers Linux is equipped with. One of the preferred features of Linux is the fact that one can run different applications at the same time on different desktops.

• Our original intentions for this project were to include an actual demonstration of the RedHat installation. Unfortunately, after many hours were invested in the attempt to install Linux, we were unsuccessful. We attribute the failed installation to incompatible hardware, and have not given up on the belief that Linux is easy to install. We plan on successfully installing Linux in the near future and will be happy to share our results with anyone interested.

Introduction

Introduction to Linux

• “line-ucks” or “lih-nicks”• Created primarily by Linus

Torvalds in 1991• First commercial release was in

March, 1992

Introduction to Linux (con’t)

• Linux is an operating system very much like Unix– Multi-tasking, multi-user

• Developed by several users to replace Minix

• Freely distributed, becoming more popular every day

Why Linux is so popular

• Free• Reliable – no crashes• Simple to use and install• Developer friendly• Runs on several different platforms• Allows older 386 and 486 processors to

run much faster• Can coexist with other OS’s

About Linux

The Linux kernel

• Originally developed for the Intel 80386 CPU’s protected mode

• Completely compatible with Unix standards

• Allows shared executables• Supports demand paging• Uses a unified memory• Supports swap space

The Linux kernel (con’t)

• Uses dynamically shared libraries extensively– Allows full library linking

• Supports a number of file systems– DOS– OS/2

• Ideally suited for application development

The Linux kernel (con’t)

• Includes several programming language compilers– C– C++– Fortran– Pascal– LISP– Ada– BASIC

Linux and DOS

• Linux provides a DOS emulator, allowing DOS applications to be executed– WINE (Windows emulator)– WABI

• Files can be transferred between the DOS and Linux file systems– Linux can access DOS partitions on a hard disk directly

Linux and TCP/IP

• Provides complete TCP/IP networking software to– Create a local area network– Attach to an existing Ethernet LAN– Connect to the internet

Linux environments

• Text-based• Graphical user interface (GUI) –

called “X” or “X Window”– Very popular, especially with users

new to Linux• KDE• GNOME

Importance of Linux’s XFree86

• XFree86 is Linux’s GUI• Easy to use• Very similar to Windows

environment– Windows users can make easy

transition

• Can install and run Windows applications

Installation Requirements

Linux installation requirements

• Minimum installation– 80386SX or better– 2 MB RAM– Floppy disk drive– 40MB hard drive– Video card– Monitor

Linux installation requirements (con’t)

• Realistic installation– Text based

• 80386 or better• 8 MB RAM

– GUI based• 80486 or Pentium class• 16 MB RAM

Linux recommended hardware

• Motherboards - ISA, EISA, PCI, VESA• RAM – 2 MB will work, 16 is best

– Multi-user – 4 MB per user

• Hard disk – IDE, EIDE, ESDI, RLL, SCSI– If using SCSI, only uses most common

• Video – Almost any• Mouse – Any• Tape – Any SCSI

Linux recommended hardware (con’t)

• Removable media – Most SCSI• Printer – Almost any parallel or

serial port• Modem – Most serial, if DOS can

use it, Linux can too• NIC – 3Com, Novell, HP, Intel

– Clones are NOT recommended!

Installation Notes

RedHat Linux 6.2 Installation Notes

• Before installation– Check hardware compatibility!!!

• www.redhat.com/support/hardware

• Make sure you have enough disk space• Decide which installation method to use

– CD-ROM– Hard Drive– Ftp– Http

RedHat Linux 6.2 Installation Notes (con’t)

• Decide how to start the installation– Bootable CD-ROM– Local media boot disk

• Included with Official RedHat Linux 6.2 set

– Network boot disk– PCMCIA boot disk

• Used if CD-ROM drive is attached to PC through PCMCIA card

RedHat Linux 6.2 Installation Notes (con’t)

• Decide which installation type you need– Workstation

• Most appropriate for Linux newbies

– Server• Most appropriate for Linux-based servers

– Custom• Allows for the greatest flexibility

– Upgrade• Upgrading to a newer version of RedHat

A Note on Workstation Installations

• There are two types available, we will choose KDE for this presentation

– GNOME• www.gnome.org

– KDE• www.kde.org

Installation methods

• CD-ROM – we will use this method– Requires a boot disk, a bootable CD-

ROM, or a PCMCIA boot disk

• Hard drive– If you have copied all RedHat Linux

file to your hard drive– Requires a boot disk or PCMCIA boot

disk

Installation methods (con’t)
