RHEL6.1 PXE网络安装

1、配置yum源，安装dhcp服务

cat /etc/yum.repos.d/my-source.repo

[my-source]

name=Red Hat Enterprise Linux $releasever - $basearch - my source

baseurl=file:///media

enabled=1

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-RedHat-release

Mount /dev/cdroom /media

Yum –y instasll dhcp

yes | find / -name dhcpd.conf.sample –exec cp -p {} /etc/dhcp/dhcpd.conf \;

过滤注释行：grep -v ^# < /etc/dhcp/dhcpd.conf

编辑dhcpd.conf 添加以下内容：
ddns-update-style interim;
ignore client-updates;
subnet 192.168.1.0 netmask 255.255.255.0 {
        option routers 192.168.1.124;
        option subnet-mask 255.255.255.0;
        next-server 192.168.1.124;
        filename "pxelinux.0";
        range 192.168.1.200 192.168.1.220;
        default-lease-time 600;
        max-lease-time 7200;
}
启动dhcp服务：

/etc/init.d/dhcpd start

Starting dhcpd: [ OK ]

2、安装tftp服务

yum search tftp ; yum -y install tftp-server

chkconfig tftp on; /etc/init.d/xinetd restart

测试tftp： tftp 192.168.1.124

tftp> get filename

3、部署安装源

Yum –y install nfs*;/etc/init.d/rpcbind start

echo "/media *(sync,ro)" >> /etc/exports; /etc/init.d/nfs star

查看共享信息：

exportfs -v

测试挂载：

mount.nfs 192.168.1.124:/media/ /opt/test

使用ftp的源：启动vsftp;mount /dev/cdroot /var/ftp/pub/linuxos;

4、部署PXE环境

获取Pxelinux.0文件需要安装pxelinux包

yum search pxelinux;yum –y install yum search pxelinux

mkdir /var/lib/tftpboot/pxelinux.cfg

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

cp /media/images/pxeboot/{vmlinuz,initrd.img} /var/lib/tftpboot/

cp /media/isolinux/isolinux.cfg /var/lib/tftpboot/pxelinux.cfg/default

修改后的default文件：

default linux

prompt 1

timeout 10

display boot.msg

menu background splash.jpg

menu title Welcome to Red Hat Enterprise Linux 6.1!

menu color border 0 #ffffffff #00000000

menu color sel 7 #ffffffff #ff000000

menu color title 0 #ffffffff #00000000

menu color tabmsg 0 #ffffffff #00000000

menu color unsel 0 #ffffffff #00000000

menu color hotsel 0 #ff000000 #ffffffff

menu color hotkey 7 #ffffffff #ff000000

menu color scrollbar 0 #ffffffff #00000000

label linux

menu label ^Install or upgrade an existing system

menu default

kernel vmlinuz

append initrd=initrd.img ks=ftp://192.168.1.124/pub/ksfile/ks.cfg

5、配置ks.cfg文件

yum -y install system-config-kickstart

运行system-config-kickstart

system-config-kickstart

Basic Configuration :

选择时区、不使用UTC clock、设置root密码Encrypt root password、体系结构x86

选择安装后重启系统

Installation Method

执行新安装、配置安装源：

方式一：FTP Server: 192.168.1.124 FTP Directory: /pub/linuxos

方式二：NFS Server:192.168.1.124 NFS Directory: /media

Boot Loader Options

默认即可、设置GRUB口令

Partition Information

清除主引导记录、删除所有现存分区、初始化磁盘标签、布局分区

最小安装包选项：

@core

@server-policy
