2 , installation method

CD-ROM installation

HDD Installation

Ftp

Nfs

HTTP

3, the installation of the start disk production

method One, in Windows can be done and burned. Among them:

Bootdisk.img Installing the boot disk image file

DRVNET.IMG Network card driver disk

DRVBLOCK.IMG block device driver disk

Pcmciadd.img PCMCIA device driver disk

method Two, in Linux to make boot disk

#dd if=bootdisk.img of=/dev/fd0 bs=1440

4. Preparation Linux Partitioning

/boot

/

Swap

Other partitions

The Linux system partition does not have the concept of a drive letter, if the user to access a partition content can go into a directory, that is , under Linux users can link the partition to a directory, which is called the link partition of the mount point

installation root partitioning is essential for Linux systems, typically requiring three partitions

know common system catalogs for Linux systems, such as:

/boot: Files to be used in the system process

/USR: System Application Folder

/home: Is the location of the user's directory

/var/log: Is the system log record partition

/dev: Store device files

/OPT: Storage of optional software for installation

/sbin: Storing standard system Management files

/tmp: Used to store temporary files

/bin: Storing standard system utilities

/etc: Store System configuration file

the lower version of the Linux boot partition must be located within the front of the hard disk

installation Linux partitions typically use ext2,ext3,vfat,raid,LVM,Reiserfs

naming rules for partitions in Linux systems:

5. Start the installation Linux

A. Introduction to Virtual Consoles

The installation process can be switched to different virtual consoles, they provide a variety of useful information and the method of entering commands under the shell, the installation process encountered problems in the location and resolution of a great help.

<Ctrl+Alt+F1>	Installation dialog box
<Ctrl+Alt+F2>	Shel Tips
<Ctrl+Alt+F4>	System-related messages
<Ctrl+Alt+F5>	Other information
<Ctrl+Alt+F3>	Installation log
<Ctrl+Alt+F7>	Graphical display

b. Local CDROM installation

Put the CD-ROM on the CD-ROM drive and start the installation Wizard

The boot: prompt waits for the user to enter a command that the user can command:

Linux or press ENTER directly

using the graphical installation interface, in this mode the user can choose the installation options, easy installation, but because the graphics ' interface occupies a lot of memory, so the installation speed is slow

Linux text

Using the text installation interface, in this mode the user can only use the keyboard to select the installation options, using this mode of installation, the installation program occupies a small amount of memory, so installation faster

Linux Rescue

Enter Linux Repair mode, in which users can repair the original Linux System file system and other errors

Linux Askmethod

means to enter Linux chooses the installation mode in which the user can choose to use one of the hard disk installation,CD-ROM,FTP,NFS,SAMBA installation Methods

Linux Expert

represents the use of Expert mode to install Linux, the so-called expert mode refers to the user can use the hardware driver to install hardware drivers during the installation process

C, the following is the REDHAT7 installation

VMware analog Real-machine installation:

First step: Mount CD Boot, select Insert Red Hat Enterprise linux7

6, shutting down and rebooting the system

(1) shutdown

function: restart/ shutdown

format:shutdown [ parameter ] time [ info ]

parameter:-R: restart

-K: Send Message

-C: Cancel the action of shutdown

-H: Turn off the computer (do not power off)

-F: Use fsck to check the file system when restarting

-F: Do not check files when restarting

Time: Set the period hh:mm a certain point

+MM Current time next few minutes

now immediately

Example:#shutdown-R now

#shutdown-R +5

#shutdown-H 18:00

(2)reboot

Function: Reboot the system

Example:#reboot

(3)halt

Function: Turn off the computer

Example:#halt
