现在网上最新的是CentOS7.1, 但是在配置国内流行的163源的时候，网上的文章大多数我这里都通不过。
错误信息大概是：
One of the configured repositories failed (CentOS-7 - Addons - 163.com),
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 addons
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=addons.skip_if_unavailable=true
更换yum源
进入yum资源仓库目录
下载163的源

[[email protected] ~]# cd /etc/yum.repos.d |
编辑repo
用vim 打开repo
用vim在一般模式使用下面的命令把$releasever全部替换为版本号，即7.1.1503。
[[email protected] yum.repos.d]# vim CentOS-Base-163.repo
:1,$s/$releasever/7.1.1503/g
:wq保存退出vim
清理原有缓存
重建缓存，
这样就能通过了。
