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; 未知的錯誤"
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

Linux虛擬機虛擬網路設定出錯
解決方案
方案一
修改網卡為動態IP
vi /etc/sysconfig/network-scripts/ifcfg-ens33 
保存退出后重啟網卡
service network restart現在可以使用yum命令了
使用完yum命令后記得將動態網卡修改回靜態網卡，方便后期操作
方案二
方案一無效的情況下可以使用方案二徹底解決
重置虛擬機虛擬網路設定
重置完虛擬網路設定后，網關地址會發生變化，記得修改/etc/hosts映射地址與/etc/sysconfig/network-scripts/ifcfg-ens33中的ip、網關地址
