curl 'http://foundation0.ilt.example.com/dvd/BaseOS/' 
#命令打开页面，确认页面下数据；注意尾部需要加/，否则将报错
curl 'http://foundation0.ilt.example.com/dvd/BaseOS/Packages/' 
#确认Packages/目录下文件
curl 'http://foundation0.ilt.example.com/dvd/BaseOS/Packages/' | grep utils
#找到yum-utils安装包
yum -y install curl 'http://foundation0.ilt.example.com/dvd/BaseOS/Packages/yum-utils-4.0.12-3.el8.noarch.rpm'
#本地化安装yum-utils，安装后命令yum-config-manger即可用
rpm -ql yum-utils 
#确认yum-utils下文件列表，输出包含命令信息

yum-config-manager --add-repo 'http://foundation0.ilt.example.com/dvd/BaseOS/'
yum-config-manager --add-repo 'http://foundation0.ilt.example.com/dvd/AppStream'
#添加存储库
find / -name "*KEY*"
#查看存储库对应密钥
rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
#将最新密钥信息导入

yum search yum
#通过搜索，确认存储库是否已成功配置
yum -y remove yum-utils
yum -y install yum-utils
#通过移除重新安装，确认存储库是否已成功配置
