手动
需要安装dhcp。vsftp。ftp。xinetd。。。。。。
yum install dhcp
vi /etc/dhcp/dhcpd.conf
ddns-update-style interim;
ignore client-updates;
subnet 192.168.1.0 netmask 255.255.255.0 {
range dynamic-bootp 192.168.1.144 192.168.1.147; #段
option domain-name-servers 8.8.8.8,192.168.1.1; #dns服务
option subnet-mask 255.255.255.0; #掩码
option time-offset -18000; #租用时间
option routers 192.168.1.1; #吓一跳，网关

在/tftp下写boots.ms 可以用第三方源 toilet
