在server ：

cd /var/lib/tftpboot/
mkdir pxelinux.cfg

在主机拷贝需要的文件：

mount the iso of the rhel7
scp isolinux/* 172.25.254.128:/var/lib/tftpboot

在server：

cp /var/lib/tftpboot/isolinux.cfg /var/lib/tftpboot/pxelinux.cfg/default
cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/

vim /var/lib/tftpboot/pxelinux.cfg/default
