  1. Unit 3 – Installing Solaris Randy Marchany VA Tech Computing Center Copyright 2002, Marchany

  2. 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. Copyright 2002, Marchany

  3. 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. Copyright 2002, Marchany

  4. 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. Copyright 2002, Marchany

  5. 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). Copyright 2002, Marchany

  6. 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 Copyright 2002, Marchany

  7. Software Cluster • A collection of several packages that logically belong together. • Examples: • Common Desktop Environment • High Performance Cluster • Freeware cluster Copyright 2002, Marchany

  8. 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. Copyright 2002, Marchany

  9. 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.

  10. Sample Scenarios Copyright 2002, Marchany

  11. 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. Copyright 2002, Marchany

  12. Preinstallation Planning • Networked? Most likely, Yes • Get hostname, IP address, subnet mask, default gateway information, DNS server locations • Have this information ahead of time. Copyright 2002, Marchany

  13. 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 Copyright 2002, Marchany

  14. 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. Copyright 2002, Marchany

  15. 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. Copyright 2002, Marchany

  16. 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 Copyright 2002, Marchany

  17. 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. Copyright 2002, Marchany

  18. 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. Copyright 2002, Marchany

  19. 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 Copyright 2002, Marchany

  20. 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. Copyright 2002, Marchany

  21. 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 Copyright 2002, Marchany
