CHAPTER 2: BASIC OF OPEN SOURCE

OPERATING SYSTEMPart 2 (Linux installation)

By the end of this chapter, students will be able to:

1)Specify the minimum hardware requirements

2)Describe the various methods of Linux installation

Example: Ubuntu Personal computer

1) 1 GHz CPU (x86 processor (Pentium 4 or better))

2) 1 GB RAM (system memory)3) 15 GB of hard-drive space (or USB stick,

memory card or external drive but see LiveCD for an alternative approach)

4) 800 by 600 screen resolution5) Either a CD/DVD drive or a USB port for the

installer media

Example: Ubuntu Server

1)300 MHz x86 processor2)128 MiB of system memory (RAM)3)1 GB of disk space4)Graphics card and monitor capable of

640x4805)CD drive

1) DVD/CD-ROM If you have a DVD/CD-ROM drive and the

installation CD, you can use this method.

2) Hard Drive If you have copied the Red Hat

Enterprise Linux ISO images to a local hard drive, you can use this method.

You need a boot CD-ROM

3) NFS If you are installing from an NFS server using ISO

images or a mirror image of Red Hat Enterprise Linux, you can use this method.

You need a boot CD-ROM Note that NFS installations may also be

performed in GUI mode.

4) FTP If you are installing directly from an FTP server,

use this method. You need a boot CD-ROM

5) HTTP If you are installing directly from an HTTP (Web)

server, use this method. You need a boot CD-ROM

The FTP dialog applies only if you are installing from an FTP server (if you selected FTP in the Installation Method dialog).

This dialog allows you to identify the FTP server from which you are installing Red Hat Enterprise Linux.

The NFS dialog applies only if you are installing from an NFS server (if you selected NFS Image in the Installation Method dialog).

Enter the domain name or IP address of your NFS server. For example, if you are installing from a host named eastcoast in the domain example.com, enter eastcoast.example.com in the NFS Server field.

Next, enter the name of the exported directory.

The HTTP dialog applies only if you are installing from an HTTP server (if you selected HTTP in theInstallation Method dialog). This dialog prompts you for information about the HTTP server from which you are installing Red Hat Enterprise Linux.

Enter the name or IP address of the HTTP site you are installing from, and the name of the directory containing the variant/ directory for your architecture.
