1. yum -y install dhcp*
2. yum -y install tftp*
3. yum -y install nfs
4. 修改tftp配置文件

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 /var/lib/tftpboot
disable = no
per_source = 11
cps = 100 2
flags = IPv4
}
Disable 的yes改成no
5挂载光盘
mount /dev/cdrom /mnt/

ln -s /var/lib/tftpboot/ /
6查找是否有
find / -name “pxelinux.0”
没有
yum -y install syslinux

7cd /tftpboot/
拷贝到当前目录
cp /usr/share/syslinux/pxelinux.0 .
8
cp /mnt/images/pxeboot/vmlinuz .
cp /mnt/images/pxeboot/initrd.img .
mkdir -p pxelinux.cfg
cd pxelinux.cfg
vi default
cp /mnt/isolinux/isolinux.cfg default
9修改default
加入
append ks=nfs:192.168.118.129:/centosinstall/ks.cfg ksdevice=eno16777736 initrd=initrd.img
10
mkdir -p centosinstall
cd centosinstall
touch ks.cfg

nohup cp -r /mnt/* .&
echo “/centosinstall *(rw，sync)” >>/etc/exports
11把root下的ks文件拷贝过来替换我们新建的ks.cfg
Chmod -R 777 ks.cfg
nfs --server = 192.168.118.128 --dir=/centosinstall
key --skip
#version=DEVEL

12修改dhcp配置文件

allow booting;

启动nfs’服务
Dhcp服务
安装虚拟机就可以使用了，失败了，改天再战
本次安装由于涉及很多服务，准备等其他服务深造一下再战，毕竟没有歌谣解决不了的难题
