Download image and extract files into some directory. I had to use separate machine, so I copied files to my ftp server (192.168.1.28).
mount -o loop /tmp/CentOS-8-x86_64-1905-boot.iso /mnt/iso scp -r * admin@192.168.1.28:/data/pub/CentOS-8.0.1905-boot umount /mnt/iso
On my tftp/ftp server:
mkdir /data/tftpboot/networkboot/CentOS8-1905
cp /data/pub/CentOS-8.0.1905-boot/images/pxeboot/vmlinuz \
/data/tftpboot/networkboot/CentOS8-1905/
cp /data/pub/CentOS-8.0.1905-boot/images/pxeboot/initrd.img \
/data/tftpboot/networkboot/CentOS8-1905/Add entry to PXE configuration (in my case /data/tftpboot/pxelinux.cfg/default):
LABEL InstallCentOS-8.0.1905
MENU LABEL Install CentOS 8 1905
kernel /networkboot/CentOS8-1905/vmlinuz
APPEND initrd=/networkboot/CentOS8-1905/initrd.img \
ip=dhcp \
inst.repo=ftp://192.168.1.28/CentOS-8.0.1905-boot
