上傳或者從其它服務器scp傳輸鏡像CentOS-7-x86_64-DVD-1908.iso到目標服務器/mnt目錄下（我這里從集群中別的服務器scp過來的）：

scp傳輸命令(1024是服務器端口，需要改成你自己的，IP地址也是同樣的需要修改)：

如果服務器上有鏡像就不用管下面這條命令

scp -P 1024 -r CentOS-7-x86_64-DVD-1908.iso root@192.168.67.200:/mnt/登錄到目標服務器查看鏡像[root@localhost mnt]# lltotal 4554750-rw-r--r-- 8 root root 4664066080 Dec 5 2016 CentOS-7-x86_64-DVD-1908.iso創(chuàng)建掛載目錄[root@localhost mnt]# mkdir /mnt/iso[root@localhost mnt]# ls4554752-rw-r--r-- 8 root root 4664066080 Dec 5 2016 CentOS-7-x86_64-DVD-1908.isodrwxr-xr-x 8 root root 2048 Dec 5 2016 iso掛載鏡像[root@localhost mnt]# mount CentOS-7-x86_64-DVD-1908.iso /mnt/iso/mount: /dev/sr0 is write-protected, mounting read-only

有的系統(tǒng)會提示錯誤需要使用mount -o loop -t iso9660

則將上面的mount語句換成下面語句：（如果你執(zhí)行上面的mount語句不報錯就跳過下面這條命令）

鏡像已經(jīng)被解壓到掛載目錄。

可以看到?jīng)]問題了，本地yum源已經(jīng)可以使用了。

以上為個人經(jīng)驗，希望能給大家一個參考，也希望大家多多支持好吧啦網(wǎng)。
