One of the three parts of the RHCE certification is an exam that tests your ability to install Linux in different situations. In this chapter, you learned to install RHEL over a network. You've also worked with the major configuration tools that are part of the installation process.
Generally, there is no easy way to resize a Linux partition. This makes hard drive partition planning quite important. How you assign partitions to directories depends on the size of your hard drives, what you plan to install, and the demands on the system. Appropriately configured partitions can prevent overloads on key systems, allow for appropriate swap space, improve security on key files, and ensure that your BIOS can find the Linux /boot files.
It's easy to download the Red Hat CDs. Whether you're using Red Hat Linux 9, Fedora Linux, Red Hat Enterprise Linux, or Professional Workstation, the basic steps are the same. You'll download ISO files which you can then write to CDs.
In most cases, you'll install Red Hat Enterprise Linux over a network. I've shown you how to set up a network installation server in this chapter. The same basic lessons apply if you're studying for the RHCE or RHCT exams using Fedora Linux or Red Hat Professional Workstation.
There are a number of ways to customize your installation. The software is organized in package groups. Red Hat starts with baseline package groups, which are the minimum requirements for the operating system. These include default packages for a functional workstation or server. You can then customize by adding or subtracting the package groups of your choice. The selections you make are critical during the Red Hat installation exams.
Before you start your installation, you need to understand the relationship between the Filesystem Hierarchy Standard and Linux directories. You can then make intelligent decisions on what directories to mount on separate partitions.
Understanding the installation process is one of the keys to success on the RHCE exam. Find a spare computer. Practice every installation scenario that you can think of. Repeat this process as you work through the advanced installation scenarios in Chapter 3.
