在CentOS 7中使用yum报错 repodata/repomd.xml: [Errno 14] HTTP Error 404 – Not Found

开始更改完/etc/yum.repos.d/CentOS-Base-repo，运行yum报错，输出如下：

[root@centos7 ~]# yum search all [K[K[K[Kini[Kt[Kitiatot[Kr

Loaded plugins: fastestmirror, langpacks

http://mirror.sohu.com/centos/7/os/x86_64/repodata/repomd.xml: [Errno 14] HTTP Error 404 – Not Found

Trying other mirror.

 

 

One of the configured repositories failed (CentOS-7 – Base),

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. Disable the repository, 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 base

 

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 much

slower). If it is a very temporary problem though, this is often a nice

compromise:

 

yum-config-manager –save –setopt=base.skip_if_unavailable=true

 

failure: repodata/repomd.xml from base: [Errno 256] No more mirrors to try.
