新建的虛擬機，想搭建一個yum，於是乎就先進行了一次本地掛載。

結果竟然掛載不上。

[root@localhost ~]# mount /root/rhel-server-6.5-x86_64-dvd.iso /mnt/

mount: /root/rhel-server-6.5-x86_64-dvd.iso is not a block device (maybe try `-o loop‘?)

經過解決，發現mount後需要加-o loop

-o loop=：使用 loop 模式用來將一個檔案當成硬盤分割掛上系統

網上有人說，iso文件鏡像都是需要添加-o loop.

[root@localhost ~]# mount -o loop /root/rhel-server-6.5-x86_64-dvd.iso /mnt/

[root@localhost ~]# ls /mnt/
