使用PXE需要kickstart，（ftp，HTTP，nfs中的一项），，tftp，DHCP，CentOS 6.4系统光盘
1）ks.cfg文件制作
[root@www share]# yum install -y system-config-kickstart
kickstart 基于 /root/anaconda-ks.cfg（本系统安装时配置的磁盘分配，时区，语言，选择的rpm包等参数）制作ks.cfg
# Partition clearing information 复制anaconda-ks.cfg中分区信息clearpart –all –initlabel part /boot –fstype=ext4 –size=500part pv.008002 –grow –size=1
volgroup vg_centos –pesize=4096 pv.008002logvol / –fstype=ext4 –name=lv_root –vgname=vg_centos –grow –size=1024 –maxsize=51200logvol swap –name=lv_swap –vgname=vg_centos –grow –size=1984 –maxsize=1984

%end
2）搭建ftp服务器准备RPM软件包
[root@www ~]# yum install -y vsftpd
[root@www ftp]#mkdir CentOS_6.4_x86_64
[root@www ftp]# mount -r /dev/sr0 /var/ftp/CentOS_6.4_x86_64
[root@www ~]# cp ks.cfg /var/ftp/kickstart/ks.cfg
3）准备Centos6.4引导文件这是关键部分（TFTP）
安装并启动tftp
[root@www ~]# rpm -ivh tftp-0.49-7.el6.x86_64.rpm

[root@www ~]# rpm -ivh tftp-server-0.49-7.el6.x86_64.rpm
Preparing… ########################################### [100%]
1:tftp-server ########################################### [100%]
[root@www ~]# chkconfig tftp on
[root@www ~]# service xinetd restart
Stopping xinetd: [ OK ]
Starting xinetd: [ OK ]
[root@www ~]# ss -uan | grep 69
UNCONN 0 0 *:69 *:*
启动文件及kernel准备
[root@www ~]# yum istall -y syslinux 此软件包准备pxelinux.0用于引导网络安装Linux
[root@www ~]# cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/
[root@www ~]# cp /var/ftp/CentOS_6.4_x86_64/isolinux/{boot.msg,splash.jpg,vesamenu.c32} /var/lib/tftpboot/ 定义CentOS 6.4默认安装界面
[root@www ~]# cp /var/ftp/CentOS_6.4_x86_64/images/pxeboot/{initrd.img,vmlinuz} /var/lib/tftpboot/
[root@www tftpboot]# mkdir pxelinux.cfg
[root@www pxelinux.cfg]# cp /var/ftp/CentOS_6.4_x86_64/isolinux/isolinux.cfg ./default
label linux
menu label ^Install or upgrade an existing system
menu default
kernel vmlinuz
append initrd=initrd.img ks=
[root@www tftpboot]# ls -lR 验证tftp上文件是否准备完毕

4）DHCP服务器安装
[root@www ~]# rpm -ivh dhcp-common-4.1.1-38.P1.el6.centos.x86_64.rpm
Preparing… ########################################### [100%]
1:dhcp-common ########################################### [100%]
[root@www ~]# rpm -ivh dhcp-4.1.1-38.P1.el6.centos.x86_64.rpm
Preparing… ########################################### [100%]
1:dhcp ########################################### [100%]
[root@www ~]# cp /usr/share/doc/dhcp-4.1.1/dhcpd.conf.sample /etc/dhcp/dhcpd.conf
subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.200 192.168.1.225;
option routers 192.168.1.1;
}
next-server 192.168.1.150; 指定tftp用于引导安装
filename=”pxelinux,0″;
[root@www ~]# service dhcpd start
Starting dhcpd: [ OK ]
5)Client准备调整BIOS启动顺序
