Loading mirror speeds from cached hostfile
Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=stock error was
14: curl#6 - "Could not resolve host: mirrorlist.centos.org; 未知的错误"One of the configured repositories failed (未知),and yum doesn't have enough cached data to continue. At this point the onlysafe thing yum can do is fail. There are a few ways to work "fix" this:1. Contact the upstream for the repository and get them to fix the problem.2. Reconfigure the baseurl/etc. for the repository, to point to a workingupstream. This is most often useful if you are using a newerdistribution release than is supported by the repository (and thepackages for the previous distribution release still work).3. Run the command with the repository temporarily disabledyum --disablerepo=<repoid> ...4. Disable the repository permanently, so yum won't use it by default. Yumwill then just ignore the repository until you permanently enable itagain or use --enablerepo for temporary usage:yum-config-manager --disable <repoid>orsubscription-manager repos --disable=<repoid>5. Configure the failing repository to be skipped, if it is unavailable.Note that yum will try to contact the repo. when it runs most commands,so will have to try and fail each time (and thus. yum will be be muchslower). If it is a very temporary problem though, this is often a nicecompromise:yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=trueCannot find a valid baseurl for repo: base/7/x86_64

这个错误表明您下载的 CentOS-Base.repo 文件内容不是有效的 Yum 仓库配置文件，而是一个 HTML 网页（可能是错误页面或跳转页面）。

问题原因：

您使用的下载链接 https://mirrors.aliyun.com/repo/Centos-vault-7.9.2009.repo 可能已经失效或不再提供直接的文件下载，而是返回了一个 HTML 页面。

解决方案
请按照以下步骤手动创建正确的仓库配置文件：

删除无效的配置文件

rm -f /etc/yum.repos.d/CentOS-Base.repo

直接手动创建配置文件
使用 vi 或 nano 编辑器创建新文件：

vi /etc/yum.repos.d/CentOS-Base.repo

将以下内容复制粘贴到文件中
