Linux red hat overview and installation Linux red hat overview and installation Presentation Transcript

  • LINUX RED HATPresented by Lonnye Bower Chris Orona Fardin Khan
  • 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.
  • Presentation Contents• Intro• About Linux• Installation Requirements• Installation Notes• RedHat 6.2 Installation• KDE• Welcome to Linux• Adding a Printer• Resources• Key Terms
  • 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!
  • Linux distributions• RedHat – www.redhat.com• Corel – linux.corel.com• Mandrake – www.linux-mandrake.com• Debian – www.debian.org• Caldera – www.caldera.com
  • Where to get Linux• CD-ROM – Fry’s, Best Buy• WWW – www.redhat.com/commerce• FTP or BBS – ftp.redhat.com/pub/redhat/current• Note: There are many other places to get Linux!
  • 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)• Ftp – If installing directly from an FTP server – Requires a network or PCMCIA boot disk• Http – If installing directly from an HTTP server – Requires a network or PCMCIA boot disk
  • Making Installation Diskettes in DOS• Insert RedHat CD into CD-ROM drive• Insert blank, formatted disk into floppy drive• Type the following – C:> d: – D:> cd dosutils – D:dosutils> rawrite – Enter disk image source file name: ..imagesboot.img – Enter target diskette drive: a: – Please insert a formatted diskette into drive A: and press –ENTER– : [ENTER] – D:dosutils>
