Could not retrieve mirrorlistarch=x 86 _ 64 repo=OS infra=container error was

143360 curl # 6-' could not resolve host : mirror Li；' Unknown error '

one of the configured repositories failed(unknown)，

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 3360

1.contact the upstream for the repository and get them to fix the problem。

2.re configure the base URL/etc . for the repository，to point to a working

up stream . 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-disable repo=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—enable repo for temporary usage :

yum-config-manager-disable repo id

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 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

用于Repo : base/7/x86 _ 64的cannot find a valid base URL

因为这种存储不能解析域名。最终，如果在不设置DNS的情况下设置DNS，然后重新启动网络，就可以解决

#编辑网络

vim/etc/sys config/network-scripts/if CFG-ens33

在#底部添加以下两行

DNS1=202.103.24.68

DNS2=202.103.44.150

#重新启动网络

Systemctl restart ne

#但是，不能在虚拟机上重新启动网络。虚拟机需要重新启动。
