错误：Cannot retrieve repository metadata (repomd.xml) for repository: base. Please verify its path and try again
When trying to install the software through yum -y install XXX, the error of Cannot retrieve repository metadata (repomd.xml) for repository: base. Please verify its path and try again appears.
Cause of the problem: The corresponding repomd.xml file cannot be found in the corresponding mirror library
Problem solving: There are no related files under the original centos/6/, try to modify the local mirror configuration file
Steps:
cd /etc/yum.repos.d
vim CentOS-Base.repo
Because $releasever obtains the version number of centos, the version obtained by my centos is 6, but there is no corresponding version file in the mirror site, so the local configuration file needs to be modified
:%s/$releasever/7/g #将文件中$releasever全部改成7或其他版本
Or replace the referenced configuration
