To address this issue please refer to the below wiki article

https://wiki.centos.org/yum-errors

If above article doesn't help to resolve this issue please use https://bugs.centos.org/.

One of the configured repositories failed (CentOS-7 - SCLo sclo),
 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=centos-sclo-sclo ...

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 centos-sclo-sclo
        or
            subscription-manager repos --disable=centos-sclo-sclo

5. Configure the failing repositor

# 原因分析
最关键的错误：
`http://mirror.centos.org/centos/7/sclo/x86_64/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found`
和：
`One of the configured repositories failed (CentOS-7 - SCLo sclo),`

也就是说
：`/etc/yum.repos.d/`里面有一个叫`centos-sclo-sclo.repo`的文件，CentOS尝试根据这个名称去指定的yum源找repomd.xml，结果找不到

# 解决办法
把`centos-sclo-sclo.repo`改名或者删除。
命令：
`mv centos-sclo-sclo.repo centos-sclo-sclo.repo.bak`
