Linux挂载本地ISO镜像源

1 创建挂载镜像的目录

mkdir /opt/rpm

2 上传iso镜像到root目录

3 挂载镜像

mount -t iso9660 /root/CentOS-7-x86_64-DVD-2207-02.iso /opt/rpm/

4 若是ftp文件夹挂载本地

mkdir /opt/iso
将ftp上software/caozuoxitong目录挂载到本地/opt/iso/ 目录
mount -t cifs //172.xxx.22.111/software/caozuoxitong /opt/iso/ -o username=root,password=password,iocharset=utf8

然后在执行mount -t iso9660 /opt/iso/CentOS-7-x86_64-DVD-2207-02.iso /opt/rpm/

5 编辑/etc/yum.repos.d/CentOS-Base.repo

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the 
# remarked out baseurl= line instead.
#
