Hands-On Novell Open Enterprise Server for
NetWare and Linux

• Chapter 12
• Installing and Working with SUSE Linux

2
Objectives

• After reading this chapter and completing the
  activities,
• you will be able to
• Describe the steps in preparing for a SUSE Linux
  installation
• Perform a SUSE Linux installation
• Use various tools to configure SUSE Linux

3
Preparing for SUSE Linux Installation

• You must know
• Hardware requirements
• How to configure a disk system

4
Hardware Compatibility

• Minimum hardware requirements
• Pentium III 750 MHz or faster processor
• 256 MB RAM (512 MB preferred)
• 4 GB hard drive (8 GB preferred)
• CD drive
• VGA adapter and monitor
• Network interface card
• Linux system components
• Linux kernel
• Input/output system
• X-Server

5
Hardware Compatibility (continued)

• Can use the command-line interface
• Starts the system and updates the driver software
• Linux kernel is independent of the GUI interface

6
Network ConfigurationPartitions

• Points to consider
• Disk system partitions-3 Primary and 60 logical
• Partitions
• Divide hard disk space into smaller functional
  units
• Partition table
• Provides information of up to four physical
  partitions
• Each partition can be divided into multiple
  logical partitions

9
Network Configuration (continued)

• SUSE Linux typical partitions
• Boot-essential system files
• Swap-page areas of memory
• Root-donated by / character
• OS files and utilities are stored
• Advantages of multiple partitions
• Faster performance
• Improves system security
• Gives you more options when setting up disk quotas

10
Network ConfigurationLinux Partition Names
11
Network ConfigurationMultiboot Configurations

• Multiboot for testing or educational servers
• Consider Virtual Disk instead
• Dual boot configurations are created by
  installing an MBR loader program that enables you
  to select the partition record to boot from.

12
Network Configuration

• Multiboot configurations
• Master Boot Record (MBR)
• Special area on the first track of a hard disk
• Stores small program that determines how to start
  OS
• Boot manager
• Responsible for starting process of loading the
  OS into memory
• Dual-boot configuration
• Enables you to select the partition record to
  boot from
• Linux boot manager programs
• LILO and GRUB

13
Network Configuration
14
Installing SUSE Linux

• Controlled by Yet Another Setup Tool (YaST)
• Installation methods
• Text-based
• GUI
• AutoYaST
• GUI-based installation is the standard method
• Beginning with SUSE Linux 6.3
• Installation steps
• Base installation
• Configuration

15
The Base Installation Phase

• Welcome screen options
• Boot from Hard Disk
• Installation
• starts the normal installation process
• Installation ACPI Disabled
• For computers that do not have Advanced
  Configuration and Power management
• (common interfaces for hardware recognition,
  motherboard and device configuration and power
  management)power management
• Installation Safe Settings
• For older computers that do not have any kind of
  power management

16
Installing SUSE Linux

• Steps
• Hardware verification
• Video driver detection
• SUSE Linux Novell software license agreement
• Select language used during installation
• Choose installation settings

17
The Base Installation Phase (continued)
18
The Base Installation Phase

• Choosing installation settings for
• Detected hardware
• Partitions
• Software to be installed
• Booting
• Time zone

19
The Base Installation Phase (continued)

• Software selection screen options
• Minimum system
• Only required package without a GUI
• Minimum graphical system (without KDE)
• With a GUI
• Full installation-fully configured server
• Default system-most commonly used software
• Select software packages you want to install
• Use Detailed Selection or Package Selection
  screens

20
The Base Installation Phase (continued)
21
The Base Installation Phase (continued)

• Booting section
• Displays boot loader type and location
• GRUB is the default boot loader
• Time Zone section
• Used to set the system to your time zone

22
The Configuration Phase

• Set the root user password
• Password restrictions
• Should be five to eight characters
• Contain both uppercase and lowercase letters
• As well as one or more numbers
• Should consist of random patterns
• Should not be based on dictionary words
• Root password is encrypted using
• Data Encryption Standard (DES Linux default)
• MD5
• Blowfish

23
The Configuration Phase (continued)

• Configure network settings
• Set your SUSE Linux servers IP address and name
• Default settings
• Get IP address from a DHCP server
• Name is set to Linux with no domain name
• Use YaST (graphical and text-based version) to
  set up these values

24
The Configuration PhaseNetwork Card
25
The Configuration PhaseAddress Setup
26
The Configuration Phase

• Perform online updates
• Download and install available updates
• Service Configuration
• Offers options to create a CA and configure LDAP
  services
• Open Enterprise Server Configuration
• Includes eDirectory and several Novell services
• Makes SUSE Linux server perform most of the
  NetWare services

27
The Configuration Phase (continued)

• Specify device configuration settings
• Review release notes
• Use Hardware Configuration window
• To specify device configuration settings

Working with SUSE Linux

• Normally you shouldnt log in as the root user
• Unless you need to perform major system tasks
• You can switch user modes
• And become the root user
• Login process
• Enter username and password
• Linux passwords are case sensitive

Using the KDE Desktop Environment

• KDE desktop
• Steps for changing default background picture
• Right-click the desktop and click Configure
  Desktop
• Click Background icon
• Click the Picture list arrow to select another
  background graphic

  performed with this utility
• By default, Konqueror window displays contents of
  a users home directory
