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.
va-scan Copyright 2002, Marchany
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
Install end-user software group on the system
Installing a desktop for a software developer
Install the developer software group
Installing a www server system
Install the entire distribution or entire/OEM group
Old system, 2 GB hard drive
Install Core operating environment

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.
va-scan Copyright 2002, Marchany
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
va-scan Copyright 2002, Marchany
System Installation
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
