当你通过 ftp 对另一台主机配置 yum 源的时候报错显示如下：

[root@client ~]# yum list               
Loaded plugins: fastestmirror
^C^Ccd ^H^H^Hcd ^H^H^CCould 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; Unknown error"One of the configured repositories failed (Unknown),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. Disable the repository, so yum won't use it by default. Yum will thenjust ignore the repository until you permanently enable it again or use--enablerepo for temporary usage:yum-config-manager --disable <repoid>4. 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

那么首先检查防火墙是或否关闭如果没有关闭就使用如下命令进行关闭
