linux中显示域名解析暂时失败

安装包的时候报错：

Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=container error was14: curl#6 - "Could not resolve host: mirrorlist.centos.org; Unknown error"

如下：

[root@one_partner ~]# yum install wgetLoaded plugins: fastestmirror, ovlDetermining fastest mirrorsCould not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=container error was14: curl#6 - "Could not resolve host: mirrorlist.centos.org; Unknown error" One of the configured repositories failed (Unknown), and yum doesnt 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 wont 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=trueCannot find a valid baseurl for repo: base/7/x86_64

出现这种保存是因为域名无法解析,归根到底就是没有设置DNS,设置下DNS，重启下网络就可以解决

# 编辑网络vim /etc/sysconfig/network-scripts/ifcfg-ens33# 在最下添加下面二行DNS1=202.103.24.68DNS2=202.103.44.150# 重启网络systemctl restart network.service# 不过我在虚拟机中重启网络还是不行，非要重启虚拟机才行。
