报错内容

已加载插件:fastestmirror
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 only
 safe 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 working
        upstream. This is most often useful if you are using a newer
        distribution release than is supported by the repository (and the
        packages for the previous distribution release still work).

     3. Run the command with the repository temporarily disabled
            yum --disablerepo=<repoid> ...

     4. Disable the repository permanently, so yum won't use it by default. Yum
        will then just ignore the repository until you permanently enable it
        again or use --enablerepo for temporary usage:

            yum-config-manager --disable <repoid>
        or
            subscription-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 much
        slower). If it is a very temporary problem though, this is often a nice
        compromise:

            yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true

Cannot find a valid baseurl for repo: base/7/x86_64

报错原因

Linux虚拟机虚拟网络设置出错

解决方案

方案一

修改网卡为动态IP

vi /etc/sysconfig/network-scripts/ifcfg-ens33 

centos7最小化安装中使用yum命令报错:14: curl#6 - “Could not resolve host: mirrorlist.centos.org; 未知的错误“

 保存退出后重启网卡

service network restart

现在可以使用yum命令了

使用完yum命令后记得将动态网卡修改回静态网卡,方便后期操作

方案二

方案一无效的情况下可以使用方案二彻底解决

重置虚拟机虚拟网络设置

centos7最小化安装中使用yum命令报错:14: curl#6 - “Could not resolve host: mirrorlist.centos.org; 未知的错误“

重置完虚拟网络设置后,网关地址会发生变化,记得修改/etc/hosts映射地址与/etc/sysconfig/network-scripts/ifcfg-ens33中的ip、网关地址
