Kickstart unattended, PXE+TFTP+FTP+DHCP

Centos6.5kickstart Unattended Installation

Method: Vsftpd+tftp+dhcp+kickstart+pxe

One: The environment a machine that has already installed the operating system (192.168.1.5) and a non-installed operating system of the machine

1. Do not install the operating system first raid, to Dell R710, for example, 6 hard disks, generally two pieces do raid1,

There are four pieces left to do RAID5.

2. Already installed the operating system of the machine first check whether to install VSFTPD,DHCPD,TFTP, if not installed, then install, close iptables,selinux.

/etc/init.d/iptables stop

Chkconfig iptables off	Close Iptables
Setenfence 0	Turn off SELinux

1) Hang on the disc image to the specified folder, this folder can be arbitrarily assigned, such as on/opt

Cd/opt/packages

RPM-IVH vsftpd* Installation vsftpd

/ETC/INIT.D/VSFTPD start	Start VSFTPD
Chkconfig vsftpd on	Boot up

Cp-r/opt/*/var/ftp/pub to the/var/ftp/pub of all the documents under OPT

2) Install TFTP and tftp-server

Yum Install tftp*-y

Vim/etc/xinetd.d/tftp

Service TFTP

{

Socket_type	= Dgram
Protocol	= UDP
Wait	= yes
User	= root
Server	=/USR/SBIN/IN.TFTPD
Server_args	=-s/var/lib/tftpboot
Disable = no				Change the original yes to No

Can

Per_source	= 11
Cps	= 100 2
flog=	= IPv4

}

/etc/init.d/xinetd start

Lsof-i:69 to see if TFTP starts properly, the TFTP process starts normally

3) Configure PXE Note I have copied the contents of the CD into the/var/ftp/pub , and then I need some files to go to this directory to test

1. Enter the Tftpboot folder, no one is built, there is no need to build

Cd/var/lib/tftpboot

2. copy pxelinux.0 and VESAMENU.C32 to Tftpboot if the Syslinux directory is not found, you need to install Yum installsystem-config-kickstart-y

Cd/usr/share/syslinux CP pxelinux.0/var/lib/tftpboot CP Vesamenu.c32/var/lib/tftpboot

3. Copy the initrd.img and Vmlinux to the Tftpboot

Cp/var/ftp/pub/image/pxeboot/initrd.img/var/lib/tftpboot Cp/var/ftp/pub/image/pxeboot/vmlinux/var/lib/tftpboot

4. Copy the isolinux/*.msg to Tftpboot cp/var/ftp/pub/isolinux/*.msg/var/lib/tftpboot

5. Create a pxelinux.cfg directory under Tftpboot and copy Isolinux.cfg to Pxelinux.cfg/default

Mkdir-p/var/lib/tftpboot/pxelinux.cfg cd/var/lib/tftpboot/pxelinux.cfg

Cp/var/ftp/pub/isolinux/isolinux.cfg/var/lib/tftpboot/pxelinux.cfg/default

6. Modify The default file and Modify permissions

Chmod 644default

Vim default Label Linux

Menu label ^install or upgrade an existing system menu default

4) Install DHCPD service

Yum Install dhcp*-y

Cp/usr/share/doc/dhcp-4.1.1/dhcpd.conf.sample/etc/dhcp/dhcpd.conf Replicating DHCP

template files, renaming

Vim/etc/dhcp/dhcpd.conf Modifying a configuration file

Ddns-update-styleinterim;

Ignoreclient-updates;

FileName "pxelinux.0";	Note that the filename position must not be placed under the subnet
Next-server 192.168.1.5;

Subnet 192.168.1.0netmask 255.255.255.0 {

#next-server 192.168.1.5; PXE server address

#filename "/var/lib/tftpboot/pxelinux.0";

#filename "pxelinux.0";

Optiondomain-name-servers 192.168.1.5;

Option routers	192.168.1.5;
Option Subnet-mask	255.255.255.0;
Range DYNAMIC-BOOTP	192.168.1.230 192.168.1.240;
Default-lease-time	21600;
Max-lease-time	43200;

}

5) Open the terminal input System-config-kickstart to select the installation parameters

Next to install the operating system of the machine can be set to network boot installed (to be in the same LAN), remember that after the installation, change the boot sequence, remember the boot does not take precedence from the network boot installation.
