Linux yum指令的一个小坑
报错信息：

One of the configured repositories failed (Bigtop),
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 bigtop
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=bigtop.skip_if_unavailable=true
failure: repodata/repomd.xml from bigtop: [Errno 256] No more mirrors to try.
解决办法：
到/etc/etc/yum.repos.d目录下查看：
和别的linux机子对比发现多了bigtop.reps文件，把这玩意删了，然后就ok。
能正常使用yum 安装的机子的yum.repos.d目录如下
