使用yun安裝軟件時有時會報repo文件的錯誤，， 主要問題出自於CentOS-Base.repo文件html
解決方案：將這個文件後綴名修改使這個文件無效docker
[root@localhost ~]# cd /etc/yum.repos.d/segmentfault
[root@localhost yum.repos.d]# mv CentOS-Base.repo CentOS-Base.repo.bakcentos
[root@localhost yum.repos.d]# ls
CentOS-Base.repo.bak CentOS-Debuginfo.repo CentOS-Media.repo CentOS-Vault.repo
CentOS-CR.repo CentOS-fasttrack.repo CentOS-Sources.repopromise
接下來能夠繼續進行yum的安裝app

當遇到這個問題的時候，發現網上也有不少人也在問一樣的問題。可是發現你們問的問題，不多有人能解釋得很清楚，並且不少人的解決方法複雜且不能解決問題。我查了近二十篇博客和文章，對照作了，可是基本解決不了問題。url

你來看看，這些問題有多少人問？可是能解決實際問題的卻不多！！！
下面由我給出一種最簡單最有效的方法。耐心看下去哦！
問題所在：
[root@cit-server6-s1-372 yum.repos.d]# yum makecache
Loaded plugins: fastestmirror
base | 5.6 kB 00:00:00
http://mirrors.163.com/centos/7/os/x86_64/repodata/repomd.xml: [Errno -1] Error importing repomd.xml for base: Damaged repomd.xml file
Trying other mirror.
One of the configured repositories failed (CentOS-7 - Base - 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 base
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=base.skip_if_unavailable=true
failure: repodata/repomd.xml from base: [Errno 256] No more mirrors to try.

錯誤所在的問題：
主要問題在於yum源問題。
下面開始解決問題：
4.下載yum依賴包
