1、配置yum源，安裝dhcp服務
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 \;
過濾注釋行：grep -v ^# < /etc/dhcp/dhcpd.conf
編輯dhcpd.conf 添加以下內容：
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;
}
啟動dhcp服務：
/etc/init.d/dhcpd start
Starting dhcpd: [ OK ]
2、安裝tftp服務
yum search tftp ; yum -y install tftp-server
chkconfig tftp on; /etc/init.d/xinetd restart
測試tftp： tftp 192.168.1.124
tftp> get filename
3、部署安裝源
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
測試掛載：
mount.nfs 192.168.1.124:/media/ /opt/test
使用ftp的源：啟動vsftp;mount /dev/cdroot /var/ftp/pub/linuxos;
4、部署PXE環境
獲取Pxelinux.0文件需要安裝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
修改後的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
運行system-config-kickstart
system-config-kickstart
Basic Configuration :
選擇時區、不使用UTC clock、設置root密碼Encrypt root password、體系結構x86
選擇安裝後重啟系統
Installation Method
執行新安裝、配置安裝源：
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
默認即可、設置GRUB口令
Partition Information
清除主引導記錄、刪除所有現存分區、初始化磁盤標簽、布局分區
最小安裝包選項：
@core
