        光盘镜像挂载

        上传或者从其它服务器scp传输镜像CentOS-7-x86_64-DVD-1908.iso到目标服务器/mnt目录下（我这里从集群中别的服务器scp过来的）：

        scp传输命令(1024是服务器端口，需要改成你自己的，IP地址也是同样的需要修改)：

        如果服务器上有镜像就不用管下面这条命令

        scp -P 1024 -r CentOS-7-x86_64-DVD-1908.iso root@192.168.67.200:/mnt/

        登录到目标服务器查看镜像

        [root@localhost mnt]# ll total  -rw-r--r-- 8 root root  Dec 5 2016 CentOS-7-x86_64-DVD-1908.iso

        创建挂载目录

        [root@localhost mnt]# mkdir /mnt/iso [root@localhost mnt]# ls  -rw-r--r-- 8 root root  Dec 5 2016 CentOS-7-x86_64-DVD-1908.iso drwxr-xr-x 8 root root 2048 Dec 5 2016 iso

        挂载镜像

        [root@localhost mnt]# mount CentOS-7-x86_64-DVD-1908.iso /mnt/iso/ mount: /dev/sr0 is write-protected, mounting read-only

        有的系统会提示错误需要使用mount -o loop -t iso9660

        则将上面的mount语句换成下面语句：（如果你执行上面的mount语句不报错就跳过下面这条命令）

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

        挂载完毕进入挂载目录查看

        [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  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

        镜像已经被解压到挂载目录。

        备份原始repo文件

        创建备份目录

        mkdir /etc/yum.repos.d/bak

        移动文件

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

        创建新的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

        刷新repo信息

        [root@localhost ~]# yum clean all Loaded plugins: fastestmirror, langpacks Cleaning repos: CDROM Cleaning up everything Cleaning up list of fastest mirrors [root@localhost ~]# yum makecache Loaded plugins: fastestmirror, langpacks CDROM | 3.6 kB 00:00:00 (1/4): CDROM/group_gz | 155 kB 00:00:00 (2/4): CDROM/primary_db | 3.0 MB 00:00:00 (3/4): CDROM/filelists_db | 3.0 MB 00:00:00 (4/4): CDROM/other_db | 1.3 MB 00:00:00 Determining fastest mirrors Metadata Cache Created

        验证一下

        总结

        可以看到没问题了，本地yum源已经可以使用了。

        以上为个人经验，希望能给大家一个参考，也希望大家多多支持本网站。
