挂载镜像

[root@rhel8-study mirrors]# mkdir -p /var/www/html/RHEL8
[root@rhel8-study mirrors]# mount -o loop -t iso9660 rhel-8.2-x86_64-dvd.iso /var/www/html/RHEL8
[root@rhel8-study mirrors]# dnf install dhcp-server tftp-server  syslinux -y

配置DHCP服务器

[root@rhel8-study mirrors]# vim /etc/dhcp/dhcpd.conf

#
# DHCP Server Configuration file.
#   see /usr/share/doc/dhcp-server/dhcpd.conf.example
#   see dhcpd.conf(5) man page
#

        range                   203.0.113.201    203.0.113.210;

        filename                "pxelinux.0";
}

[root@rhel8-study mirrors]# cp  /var/www/html/RHEL8/isolinux/{vmlinuz,ldlinux.c32,initrd.img}       /var/lib/tftpboot/  
[root@rhel8-study mirrors]# mkdir /var/lib/tftpboot/pxelinux.cfg

[root@rhel8-study mirrors]# vim /var/lib/tftpboot/pxelinux.cfg/default #生成default文件
