- 部署default默认的菜单文件
[[email protected] ~]# mkdir /var/lib/tftpboot/pxelinux.cfg #新建菜单文件路径
[[email protected] ~]# cp /mnt/isolinux/isolinux.cfg /var/lib/tftpboot/pxelinux.cfg/default #拷贝菜单文件到系统默认目录
[[email protected] ~]# chmod 644 /var/lib/tftpboot/pxelinux.cfg/default #文件增加权限644
[[email protected] ~]# cp /mnt/isolinux/vesamenu.c32 /var/lib/tftpboot/ #拷贝开机图形模块文件到默认目录
