配置 dhcp

vim /etc/dhcp/dhcpd.conf subnet 192.168.43.0 netmask 255.255.255.0 { range 192.168.43.100 192.168.43.200; option routers 192.168.43.2; option domain-name "xuepeng.com"; option domain-name-servers 180.76.76.76, 114.114.114.114; next-server 192.168.43.8; filename "pxelinux.0"; }

立即启动，开机自启动服务

systemctl enable --now tftp dhcpd httpd

准备相关目录挂载光盘提前添加三张光驱，分别放入centos6,7,8的光盘

mkdir -p /var/www/html/Centos/{6,7,8}/os/x86_64 mount /dev/sr0 /var/www/html/Centos/8/os/x86_64/ mount /dev/sr1 /var/www/html/Centos/6/os/x86_64/ mount /dev/sr2 /var/www/html/Centos/7/os/x86_64/

将ks文件移动到 /var/www/html/ksdir Centos6，7，8 ks.cfg

mkdir /var/www/html/ksdir mv ks{6,7,8}.cfg /var/www/html/ksdir

准备启动相关文件放到 /var/lib/tftpboot 目录下

initre.img , vmlinuz 来自光盘
menu.c32， pxelinux.0 来自 syslinux-nonlinux 软件包
ldlinux.c32 ， libcom32.c32，libutil.c32 来自 centos8的光盘
pxelinux.cfg 自己创建的目录
