  1. Linux Install

  2. Resources • Guide to Linux Installation and Administration, Nicholas Wells, Course Technology, 2000

  3. Hard Disk Partitions • Swap partition • Linux partition • Make Linux partition active partition

  4. Hard disk • Device name • /dev/hda • /dev/hdb • CD-ROM • /dev/hdc if it’s the third IDE device • Partition name • /dev/hdb1 • Refers to first partition on the second IDE disk • SCSI • /dev/sda

  5. Mount points • Linux uses “subdirectory” structure to access devices • No “drive letters” such as “A:”, “C:”, etc. • What is a mount point? • Subdirectory in which a set of data is accessed • Names are arbitrary • Standard names exist by convention • ‘root’ is the only mount point you must specify • Define the hard disk partition which holds the root directory structure

  6. Mount points • Devices such as floppy drive and CD-ROM drives can be mounted and ‘unmounted’ • Not permanently available

  7. Mount Points • /mnt/floppy • Floppy drive • / • “main” hard disk partition in Linux • /opt • Secondary Linux partition or second Windows drive • /mnt/cdrom • CD-ROM drive • /remote_home • Network server home directory

  8. Possible usage of disks • Core OS places on one hard disk • User directories on second disk • Applications / data on third disk • Configuration is defined at install time • Segregation of data • Allows upgrade of OS w/o impact to user files • Ensures user data won’t fill up OS drive • Eases backup / restore of information • Lends itself to security administration • R/W performance issues

  9. fdisk • Prepares a partition for usage • Command line interface • m help • n new partition • p primary partition • Multiple partitions per hard disk using extended / logical partitions • t type of partition (uses code numbers)

  10. DiskDruid • “gui” interface for partitioning disks • Will suggest a configuration • Creates mount points for Linux subdirectories

  11. Installation Type • Workstation • Server • Custom

  12. Boot Loader • Placement of LILO • Linux Loader • MBR • BIOS passes control to LILO, invoking Linux • May have problems with other OS on machine (Windows) • Boot sector of Linux install partition • BIOS to MBR, to copy of LILO on Linux partition • Linux partition must be marked as “bootable” • Allows for booting to another OS • Floppy • Start Linux from floppy, leaving MBR intact

  13. root user • Administrative user name • “superuser” • Create “regular” user accounts

  14. Linux version • Features and support available depend on version of Linux • Kernel contains support and drivers • Not all hardware supported
