Linux如何配置本地yum源(光盤鏡像掛載)

更新時間：2023年05月29日 15:07:05 作者：slyybw

這篇文章主要介紹了Linux如何配置本地yum源(光盤鏡像掛載)，具有很好的參考價值，希望對大家有所幫助。如有錯誤或未考慮完全的地方，望不吝賜教

光盤鏡像掛載

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]# ll
total 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]# ls
4554752
-rw-r--r-- 8 root root 4664066080    Dec  5  2016 CentOS-7-x86_64-DVD-1908.iso
drwxr-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）

mount -o loop -t iso9660 CentOS-7-x86_64-DVD-1908.iso  /mnt/iso

掛載完畢進入掛載目錄查看

[root@localhost mnt]# cd iso/
[root@localhost iso]# ll
total 654
-rw-r--r-- 1 root root     14 Dec  5  2016 CentOS_BuildTag
drwxr-xr-x 3 root root   2048 Dec  5  2016 EFI
-rw-r--r-- 1 root root    215 Dec 10  2015 EULA
-rw-r--r-- 1 root root  18009 Dec 10  2015 GPL
drwxr-xr-x 3 root root   2048 Dec  5  2016 images
drwxr-xr-x 2 root root   2048 Dec  5  2016 isolinux
drwxr-xr-x 2 root root   2048 Dec  5  2016 LiveOS
drwxrwxr-x 2 root root 630784 Dec  5  2016 Packages
drwxrwxr-x 2 root root   4096 Dec  5  2016 repodata
-rw-r--r-- 1 root root   1690 Dec 10  2015 RPM-GPG-KEY-CentOS-7
-rw-r--r-- 1 root root   1690 Dec 10  2015 RPM-GPG-KEY-CentOS-Testing-7
-r--r--r-- 1 root root   2883 Dec  5  2016 TRANS.TBL

鏡像已經(jīng)被解壓到掛載目錄。

備份原始repo文件

創(chuàng)建備份目錄

mkdir  /etc/yum.repos.d/bak

移動文件

mv    /etc/yum.repos.d/*.repo /etc/yum.repos.d/bak/

創(chuàng)建新的repo文件

新建Centos-CDROM.repo文件

vi /etc/yum.repos.d/Centos-CDROM.repo
[CDROM]
name=CentOS-$releasever - CDROM
baseurl=file:///mnt/iso
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
