Unit 1: Installing Linux




          1.2 The Installation                                                                  Notes

          Different types of installation methods are available. You can select any one from them.

          z z  CD-ROM: If you have a CD-ROM drive and the Red Hat Linux CD-ROMs, you can use this
               method. You will need a boot diskette or a bootable CD-ROM. A PCMCIA driver diskette
               may also be used.
          z z  Hard Drive: If you have copied the Red Hat Linux ISO images to a local hard drive, you
               can use this method. You will need a boot diskette. A PCMCIA driver diskette may also
               be used.
          z z  NFS Image: If you are installing from an NFS server using ISO images or a mirror image
               of Red Hat Linux, you can use this method. You will need a network driver diskette. A
               PCMCIA driver diskette may also be used. Please note that NFS installations may also be
               performed in GUI mode.

          z z  FTP: If you are installing directly from an FTP server, use this method. You will need a
               network driver diskette. A PCMCIA driver diskette may also be used.

          z z  HTTP: If you are installing directly from an HTTP (Web) server, use this method. You will
               need a network driver diskette. A PCMCIA driver diskette may also be used.

          1.2.1 Installing Red Hat Linux

          There is quite a variety of Linux distributions from which to choose from. Each distribution offers
          the same base Linux kernel and system tools, but differ on installation method and bundled
          applications. Each distribution has its own advantages as well as disadvantages, so it is wise
          to spend a bit of time researching which features are available in a given distribution before
          deciding on one.

          The installation of a Linux system requires a little more up-front research than does a Windows
          installation.  As  many  Linux  device  drivers  are  created  through  community-based  reverse-
          engineering, rather than by those devices’ manufacturers, it’s important to check a number of
          hardware compatibility lists prior to commencing the installation. This will help you ensure that
          drivers exist for the devices on your server.
          Linux  support  can  take  many  forms,  the  most  popular  being  Web-based  lists  and  forums.
          This approach truly represents the spirit of community in the open source world, where user
          experience is relied upon to provide solutions to Linux issues. All commercial Linux distributors
          provide some level of paid support, though  the support period may vary widely from one
          distributor to another.
          Linux systems can be installed with a full complement of graphical tools, or as a minimal text-
          based system. The installers follow suit, providing options to complete an installation from a
          graphical environment, or from a purely text-based environment.
          Unlike Windows systems, the desktop environment is not inextricably bound to the operating
          system kernel code. Instead, the X Windows and desktop management systems are distinct systems
          that run in their own space. This feature of Linux allows for the creation of a fully operational,
          text-based system, which boasts a very small installation code base. However, most users will opt
          for a graphical system based on X Windows and any of a number of desktop managers.

          1.2.2 Creating a Boot Disk

          In order to install Linux, we must begin by booting the Linux kernel. This is accomplished in
          exactly the same manner as if you wanted to reload MS-DOS: we need a boot disk. But most
          distributions  come  only  with  a  CD-ROM,  and  even  if  we  had  a  running  Linux  system,  the
