Verify Partitioning

• In most cases, YaST proposes a reasonable
  partitioning scheme
• You might change the partitioning manually if
• You want to optimize the partitioning scheme
• You want to configure LVM
• You have more than one hard drive and want to
  configure RAID
• You want to delete existing operating systems

12
Verify Partitioning (continued)

• The basics of hard drive partitioning
• Partitions divide the available space of a hard
  drive into smaller portions
• A partition table has space for four entries
• A primary partition consists of a continuous
  range of cylinders assigned to a particular file
  system
• An extended partition consists of a continuous
  range of disk cylinders
• Can be subdivided into logical partitions
• Logical partitions do not require entries in the
  main partition table

15
Verify Partitioning (continued)

• The basic Linux partitioning scheme
• Swap partition
• Used by Linux to move unused data from the main
  memory to the hard drive
• Root partition
• Holds the top (/) of the file system hierarchy,
  the so-called root directory
• YaSTs partitioning proposal
• Use YaST to change the partition scheme
• Select the Partitioning headline in the
  installation proposal

Verify Partitioning (continued)

• Delete existing partitions
• You delete all logical partitions when you delete
  an extended partition
• If you select the entry for the entire hard disk
  and select Delete, all partitions on the disk are
  deleted
• Resize existing partitions
• See Figure 1-11

21
Verify Partitioning (continued)

22
Verify Partitioning (continued)

• Perform expert tasks
• Reread the Partition Table
• Import Mount Points from Existing /etc/fstab
• Delete Partition Table and Disk Label

23
Select Software

• SLED 10 contains many software packages for
  various application purposes
• You can select various software categories
• See Figure 1-12
• A package typically contains an application and
  all additional files required to use the software
• SUSE Linux Enterprise Software uses the RPM
  Package Manager for software management
• RPM packages contain dependencies information

24
Select Software (continued)

25
Start the Installation Process

• Before installing software packages, YaST changes
  the hard disk partitioning
• Depending on your software selection and the
  performance of your system
• The installation process takes 15 to 45 minutes
• After all software packages are installed, YaST
  reboots the computer and prompts you for some
  configuration information

26

• root has unlimited power to do anything
• root account should only be used for system
  administration, maintenance, and repair
• Set the root password during the installation
  process
• See Figure 1-15

Exercise 1-1 Install SUSE Linux Enterprise
Desktop 10

• In this exercise, you install SUSE Linux
  Enterprise Desktop 10
• Detailed steps to complete this exercise

Summary

• A SUSE Linux installation is typically started by
  booting from DVD installation media and selecting
  options from an installation boot screen
• After the installation program has loaded into
  computer memory, YaST prompts you for
  installation settings
• Before Linux can use a hard disk, it must first
  be partitioned
• At minimum, you must create a root and swap
  partition during an SLES installation

42
Summary (continued)

• The YaST Expert Partitioner allows you to create
  RAID, LVM, and EVMS partitions in addition to
  simple Linux partitions
• On the first boot following package installation,
  you are prompted for a root user password
• At the end of the installation process, you can
  change hardware device settings
