Introduction
 Solaris 8 versions
– Platform Editions – SPARC, Intel
– International Edition – multilingual versions in
European and Asian languages
– Hardware Releases – labeled MM/YY, for
example, Solaris 8 2/02. Updated editions with
new device driver, updated patches, etc.

Installation Options
 Interactive – GUI driven and the one I use the
most. Only installs the OS and no other products.
 Web Start 3.0 – JAVA powered GUI that installs
the OS and any other packages.
 Network Install – install from a server. Used
more in the labs and quite effective in rebuilding
systems quickly. Allows multiple systems to be
installed simultaneously.

Installation Options
 Default JumpStart – allows a new system
to be installed under a default setup.
 Custom Jumpstart – sysadmin defines the
configuration for various models and the
system is tailored to that configuration
automatically.

Installation Requirements
 Platforms – SPARC or Intel/X86. See
www.sparc.com for a list of other manufacturers.
 Disk Space – full blown Solaris requires 2.5GB.
Most systems ship with a 20GB drive so this
shouldn’t be a problem.
 Memory – 128MB minimum but preferably
256MB.
 Hardware – attached CDROM or network
interface card (NIC).

Software Packages
 Pkginfo file – contains info about the package, its
title, purpose, version.
 Pkgmap file – contains the names, locations,
sizes and permissions of all of the files.
 Preinstall script – queries the installer about what
components to install, where to install them and
how to configure them
 Binary files – the actual executable binaries
 Removal script – ensures all components are
removed

Software Cluster
 A collection of several packages that
logically belong together.
 Examples:
– Common Desktop Environment
– High Performance Cluster
– Freeware cluster

Software Groups
 Core – SUNWCreq, minimum required
software for a system to run. No man
pages, GUI, Java, compiler/development
tools. Takes up about 700MB of disk.
 End-user – SUNWCuser, generally
considered for a desktop workstation.
Core, GUI, Java, man pages, WWW
browser. Uses 1.2GB of disk.

Software Groups
 Developer – SUNWCprog, contains all of the
previous groups plus programming tools,
software libraries, include files, etc. Uses about
1.9GB of disk
 Entire – SUNWCall, all of the above plus WWW
server, DHCP server, NFS and freeware utilities.
Requires about 2GB.
 Entire + OEM – SUNWCxall, all of the above
plus HW drivers for OEM equipment. Use this if
you’re not sure what HW will be installed on the
system. Uses about
2.9GB of disk.

Sample Scenarios
Installing a desktop for a
user who only runs
remote applications
Installing a desktop for a
software developer
Installing a www server
system
Install end-user software
group on the system
Install the developer
software group
Install the entire
distribution or
entire/OEM group
Old system, 2 GB hard
Install Core operating

Preinstallation Planning
 Decide if your system is a client,
standalone or server.
– Client – part or all of the Solaris OS is on
another system.
– Standalone – all of Solaris is on the system
– Server – provides some form of service to
other systems – NFS, etc.

Preinstallation Planning
 Networked? Most likely, Yes
– Get hostname, IP address, subnet mask,
default gateway information, DNS server
locations
– Have this information ahead of time.

System Installation
 Power On Sequence
– POST – ensures all the HW is connected and
working
– Prom environment variable auto-boot? Should
be set to FALSE.
– When you get the OK prompt, insert the OS cd
and enter ‘boot cdrom’ to start the installation
process

You’ll be prompted for the following:
Networked? Yes
DCHP? No
Hostname? Enter fully qualified host name
IP address? Enter your assigned address
Subnet mask? Enter your subnet mask
IPv6? Yes but you can say No
Type of service? Select OTHER or NONE.

System Installation
 Enter geographic region, date/time, root
password information when prompted.
 Power management? No!
 Proxy server? N/A in most cases
 Confirmation Screen? Read the
information carefully and if it’s accurate,
hit CONFIRM. Remember, you can always
start over from the beginning if you want.

System Installation
 Default or custom install? Select default unless
you know what you’re doing.
 If you choose Custom Install:
– Select the internationalization option
– Select the Products you want
– Select 64 bit support unless you have specific
applications that can’t run in that environment.
– Select the appropriate software group to be installed

Disk Configuration
 Complicated because the defaults are never
enough and if you don’t get it right during
installation, you’ll have to reinstall later to fix it.
 We reviewed the basics in an earlier unit.
 The first screen has 2 windows.
– Left window contains available disks
– Right window contains the disks you’ve selected for
the install. You can spread the OS across multiple
disks if you want. No gain from that, however.

Disk Configuration
 Carefully check the selected boot disk.
Click NEXT to go to the next screen.
 This window contains the default disk
layout. I never use these values.
– Press MODIFY to change the disk layout.
Have an idea of what you want ahead of time.
– Advantage of spreading filesystems across
partitions is that backups are easier to do.

Disk Configuration
 Some recommendations:
 / - 128MB minimum
 /var – 2GB minimum, syslogs are stored here by
default so you want enough space to hold them
 /opt – 2-2.5GB minimum, this is the default
location for all Solaris system software packages.
You need this much space for compilers,
freeware tools, etc.
 /home – size as needed for your users

System Installation - Final
 Once you’ve laid out the file systems, you will
then get a confirmation screen listing all of the
information you’ve entered so far.
 Review the information and if it’s correct, press
the INSTALL NOW button. Note, that up to this
point, your old system is still preserved. You
could abort the install process and reboot under
the old, existing system.
 Once you hit the INSTALL NOW button, you’re
committed.

Software Packages, Clusters,
Groups
 Solaris 8 software is organized into 3
components.
 Package – collection of files and
information necessary install software. A
compiler is an example.
 Cluster – logical collection of software
such as windowing software.
 Group – collection of clusters
