下面由centos教程栏目给大家介绍centos8基于pxe自动安装操作系统，希望对需要的朋友有所帮助！
pxe服务器配置安装相关软件dnf install -y httpd tftp-server dhcp-server syslinux-nonlinux
配置 dhcpvim /etc/dhcp/dhcpd.confsubnet 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_64mount /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/ksdircentos6，7，8 ks.cfg
mkdir /var/www/html/ksdirmv 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
