Chapter 15: Performing Advanced Installation


Overview

Installing an OS on a large number of machines can be a very time consuming and cumbersome activity. When you need to do the same thing over and over again, it is time for automation. Not only is doing the same thing manually over and over again time consuming but it can also lead to error. For example, if all 25 machines need to have the same value for a configuration parameter, some of these machines may end up having a different value due to human error. That's why the JumpStart installation method offers not only time saving but also a robust automated way to install Solaris on a group of machines that have identical configuration and software requirements. In a different situation, you may need to make a number of identical installations by using an image of an already installed system. This is accomplished through the flash archive installation method. Another installation situation is related to an x86 machine that does not have a local medium to boot from. This is addressed by the PXE installation method. If you want to install another application (or a set of applications) that require an isolated environment, you will need to install Solaris on another machine on which this set of applications will run. The question is: can I create multiple, isolated environments on one machine? The Solaris zone technology provides the answer to this question with a resounding yes.

So, the core issue in this chapter to think about is how to use the advanced installation methods offered by Solaris. To address this issue, we will explore three thought streams: JumpStart and files archive installation methods, the PXE method for booting an x86 machine, and Solaris zone technology.
