PXE+DHCP+TFTP+HTTP+KS

11ho

系统Centos 6.3 x86_64

vim /etc/sysconfig/i18n

LANG=" zh_CN.utf-8"

export.utf-8

测试所需设备:

1.DHCP 服务器

2.TFTP 服务器

3.KickStart所生成的ks.cfg配置文件

4.一台存放系统安装文件的服务器，如 NFS、HTTP 或 FTP 服务器，本文选择HTTP进行

5.带有一个 PXE 支持网卡的将安装的主机

1、安装相应的软件包

yum -y install httpd* tftp-server system-config-kickstart dhcp syslinux

挂载CentOS6.3的DVD光盘，并复制第一张光盘下的所有内容到/var/www/html/centos6/

mkdir -p /var/www/html/centos6

mount /dev/sr0 /mnt

cp -rf /mnt/* /var/www/html/centos6

2、配置tftp，启动http、tftp服务

vim /etc/xinetd.d/tftp

# default: off

# description: The tftp server serves files using the trivial file transfer \

#protocol.The tftp protocol is often used to boot diskless \

#workstations, download configuration files to network-aware printers, \

#and to start the installation process for some operating systems.

service tftp

{

socket_type= dgram

protocol= udp

wait= yes

user= root

server= /usr/sbin/in.tftpd

server_args= -s /tftpboot

disable= no

per_source= 11

cps= 100 2

flags= IPv4

}

3、配置dhcp

vim /etc/dhcp/dhcpd.conf

ddns-update-style interim;

ignore client-updates;

next-server 192.168.205.128;#PXE服务器IP地址

filename "/pxelinux.0";

subnet 192.168.205.0 netmask 255.255.255.0 {

# --- default gateway

option routers192.168.205.2;#网关

option subnet-mask255.255.255.0;#子网掩码

#option nis-domain"domain.org";

#option domain-name"domain.org";

option domain-name-servers1.2.4.8;#DNS服务器

option time-offset-18000; # Eastern Standard Time

#option ntp-servers192.168.1.1;

#option netbios-name-servers192.168.1.1;

# --- Selects point-to-point node (default is hybrid). Don't change this unless

# -- you understand Netbios very well

#option netbios-node-type 2;

range dynamic-bootp 192.168.205.80 192.168.205.90;#DHCP下放地址段

default-lease-time 21600;

max-lease-time 43200;

# we want the nameserver to appear at a fixed address

#host ns {

#next-server marvin.redhat.com;

#hardware ethernet 12:34:56:78:AB:CD;

#fixed-address 207.175.42.254;

#}

}

4、配置支持PXE启动

mkdir -p /tftpboot/pxelinux.cfg

cp /usr/share/syslinux/pxelinux.0 /tftpboot

cd /mnt/images/pxeboot/;cp initrd.img vmlinuz /tftpboot

cp /mnt/isolinux/*.msg /tftpboot

cp /mnt/isolinux/isolinux.cfg /tftpboot/pxelinux.cfg/default

service dhcpd restart

service xinetd restart

service httpd restart

chkconfig --level 35 httpd on

chkconfig --level 35 dhcpd on

chkconfig --level 35 xinetd on

关闭SELINUX

sed -i 's/\(SELINUX=\)\(.*\)/\1disabled/' /etc/selinux/config

vim /tftpboot/pxelinux.cfg/default

default linux
