系统Centos6.5x86_64
ip:192.168.1.201
测试所需设备:(注意自己的dhcp网段修改,还有ip地址)
1.DHCP服务器
2.TFTP服务器
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 install httpd tftp-server system-config-kickstart dhcpsyslinux -y
挂载CentOS6.5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-r /dev/cdrom/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:Thetftpserverservesfilesusingthetrivialfiletransfer\
#protocol.Thetftpprotocolisoftenusedtobootdiskless\
#workstations,downloadconfigurationfilestonetwork-awareprinters,\
#andtostarttheinstallationprocessforsomeoperatingsystems.
servicetftp
{
socket_type=dgram
protocol=udp
wait=yes
user=root
server=/usr/sbin/in.tftpd
server_args=-s@H_404_132@/tftpboot
disable=@H_404_132@no
per_source=11
cps=1002
flags=IPv4
}
3、配置dhcp
# vim /etc/dhcp/dhcpd.conf
#dhcpd.conf
optiondomain-name "cnlinux.com";
optiondomain-name-servers 114.114.114.114;
default-lease-time86400;
max-lease-time86400;
log-facilitylocal7;
subnet192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.240 192.168.1.250;
option routers 192.168.1.1;
filename "pxelinux.0";
next-server 192.168.1.202;
}
4、配置支持PXE启动
# mkdir-p/tftpboot/pxelinux.cfg
# cp /usr/share/syslinux/pxelinux.0 /tftpboot/
# cd/mnt/images/pxeboot/;cpinitrd.imgvmlinuz/tftpboot
# cp /mnt/isolinux/boot.msg/tftpboot/
# cp /mnt/isolinux/vesamenu.c32 /tftpboot/
# cp /mnt/isolinux/splash.jpg/tftpboot/
# cp /mnt/isolinux/isolinux.cfg/tftpboot/pxelinux.cfg/default
# servicedhcpdrestart
# servicexinetdrestart
# servicehttpdrestart
# chkconfig--level35httpdon
# chkconfig--level35dhcpdon
# chkconfig--level35xinetdon
关闭selinux
# setenforce 0
# sed -i "s@SELINUX=enforcing@SELINUX=disabled@g"/etc/sysconfig/selinux
关闭iptables
# /etc/init.d/iptables stop
# chkconfig iptables off
# vim/tftpboot/pxelinux.cfg/default
default linux

最后构建一台服务器，会自动装机。
下图是在安装途中的。
下面是安装成功后 自动重启 然后输入密码登入的机器
