tailieunhanh - Advanced Installation

In this chapter, you will learn how to manage Linux in advanced installation and configuration scenarios. The installation topics cover creating automated installation scripts and managing kernel modules. You will learn how to implement a Redundant Array of Inexpensive Disks (RAID), as well as an array of disks for the Logical Volume Manager (LVM), and master the intricate details of the automated Kickstart installation process. Finally, you’ll get a basic sense of how you can modularize the kernel to your advantage | RHCE RED HAT CERTIFIED ENGINEER 5 Advanced Installation CERTIFICATION OBJECTIVES Q A RAID Configuration Using Kickstart to Automate Installation Understanding Kernel Modules The lib modules keme _vers onZ Directory Structure Two-Minute Drill Self Test 250 Chapter 5 Advanced Installation In this chapter you will learn how to manage Linux in advanced installation and configuration scenarios. The installation topics cover creating automated installation scripts and managing kernel modules. You will learn how to implement a Redundant Array of Inexpensive Disks RAID as well as an array of disks for the Logical Volume Manager LVM and master the intricate details of the automated Kickstart installation process. Finally you ll get a basic sense of how you can modularize the kernel to your advantage. Remember one of the three RHCE exams is based on how well you know the installation process. By the time you finish this chapter you should be ready to install Linux in an automated fashion from a local boot disk or over a network from an NFS or HTTP server. And as you work with kernel modules near the end of the chapter you ll examine some of the techniques you can use on the RHCE troubleshooting exam to ensure that the kernel is properly set up to work with your hardware. CERTIFICATION OBJECTIVE RAID Configuration A Redundant Array of Independent Disks RAID is a series of disks that can save your data even if there is a catastrophic failure on one of the disks. While some versions of RAID make complete copies of your data others use the so-called parity bit to allow your computer to rebuild the data on lost disks. Linux RAID has come a long way. A substantial number of hardware RAID products support Linux especially from name brand PC manufacturers. Dedicated RAID hardware can ensure the integrity of your data even if there is a catastrophic physical failure on one of the disks. Alternatively you can configure software-based RAID on multiple .
