无法检索MirrorList http://httpupdate.cpanel.net/cpanel-plugins-clatest-x86_64-mirrorlist错误是14：HTTP错误404-找不到
配置的存储库之一失败（未知）， YUM没有足够的缓存数据继续进行。在这一点上 安全的事情就是失败。有几种工作"修复"的方法：
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 <repoid>
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=<repoid>.skip_if_unavailable=true
找不到repo的有效baseurl：cpanel-plugins/lestest/x86_64
多天后，我自我找到了答案。
这是解决方案
1.安装CPANEL后，您必须立即运行命令>
/scripts/configure_firewall_for_cpanel
