CentOS7.5配置本地yum源

上传centos ISO镜像到/media

[root@hwdb1 ~]# cd /media
[root@hwdb1 media]# ls
CentOS-7-x86_64-DVD-1804.iso

将iso挂载到目录

[root@hwdb1 ~]# cd /media/
[root@hwdb1 media]# ls
CentOS-7-x86_64-DVD-1804.iso
[root@hwdb1 media]# mkdir disk
[root@hwdb1 disk]# mount -o loop -t iso9660 /media/CentOS-7-x86_64-DVD-1804.iso  /media/disk
mount: /media/CentOS-7-x86_64-DVD-1804.iso 已经挂载

创建yum配置文件

[root@hwdb1 ~]# cat /etc/yum.repos.d/CentOS-Base.repo 
[base]
name=CentOS-$releasever - Base
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os&infra=$infra
baseurl=file:///media/disk/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
