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 (Kibana repository for 5.5.x packages), 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=kibana-5.5 ...
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 kibana-5.5 or subscription-manager repos --disable=kibana-5.5 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=kibana-5.5.skip_if_unavailable=true failure: repodata/repomd.xml from kibana-5.5: [Errno 256] No more mirrors to try. https://packages.elastic.co/kibana/5.5/centos/repodata/repomd.xml: [Errno 14] HTTPS Error 404 - Not Found
解决
上面这一大段，可得到两个信息：
yum的源出了问题
出问题的源是kibana (上面最后两行)
请仔细辨别你的提示，不同提示对应不同源
知道问题原因后，我们进入yum存放源的目录

$ cd /etc/yum.repos.d/
$ ls backup CentOS-Base.repo docker-ce.repo epel.repo kibana.repo zabbix.repo
