Cannot retrieve repository metadata (repomd.xml) for repository: base. Please verify its path and tr

镜像下载、域名解析、时间同步请点击 阿里云开源镜像站

错误：Cannot retrieve repository metadata (repomd.xml) for repository: base. Please verify its path and try again

通过yum -y install XXX 尝试安装软件，出现Cannot retrieve repository metadata (repomd.xml) for repository: base. Please verify its path and try again的错误

问题原因：对应的镜像库中无法找到对应的repomd.xml文件

问题解决：原centos/6/ 下已经没有相关的文件，尝试修改本地镜像配置文件

步骤：

cd /etc/yum.repos.d 

vim CentOS-Base.repo 

因为$releasever 获取的是centos的版本号，我的centos获取的版本为6，但是镜像站中无对应版本文件，因此需要修改本地配置文件

:%s/$releasever/7/g #将文件中$releasever全部改成7或其他版本 

或者替换参考的配置

退出保存

:wq 

清除和重新生成缓存

yum clean all  yum makecache  

完成之后再次通过yum -y install XXX 尝试安装软件
