mount /dev/cdrom /test mkdir /tftpboot/CentOS7.2 cp /test/isolinux/{vmlinuz,initrd.img} /tftpboot/CentOS7.2 cp /test/isolinux/isolinux.cfg /tftpboot/pxelinux.cfg/default
其实仅需要vmlinuz和initrd.img两个文件即可，不过这里还将isolinux.cfg这个文件拷贝出来了，这个文件里提供了开机选项，可以以它作为修改开机选项和菜单的模板，这样修改起来比较容易，也更便捷！
1.8 设置开机菜单并提供系统安装文件以下是CentOS 7.2中syslinux包中提供的isolinux.cfg中提供的默认内容。

所以，将其稍作修改，使其适合做pxe的菜单配置文件。
