博客记录了使用yum install zip命令时，出现MySQL 5.7社区服务器仓库HTTP 404错误，yum无法继续的问题。给出的处理办法是进入/etc/yum.repos.d目录，删除mysql-connectors-community.repo和mysql-tools-community.repo文件。

To address this issue please refer to the below knowledge base article

https://access.redhat.com/articles/1320623

If above article doesn’t help to resolve this issue please create a bug on https://bugs.centos.org/

One of the configured repositories failed (MySQL 5.7 Community Server),
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=mysql57-community ...

 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 mysql57-community
    or
        subscription-manager repos --disable=mysql57-community

 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=mysql57-community.skip_if_unavailable=true

failure: repodata/repomd.xml from mysql57-community: [Errno 256] No more mirrors to try.

处理
cd /etc/yum.repos.d下
删除mysql-connectors-community.repo、mysql-tools-community.repo
