安装svn的时候，发现报错说一个地址无法访问。
# yum list | grep subversion
http://opensource.wandisco.com/centos/7/svn-1.8/RPMS/x86_64/repodata/repomd.xml: [Errno 14] curl#6 - "Couldn't resolve host 'opensource.wandisco.com'"

One of the configured repositories failed (Wandisco SVN Repo),
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 WandiscoSVN
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=WandiscoSVN.skip_if_unavailable=true
failure: repodata/repomd.xml from WandiscoSVN: [Errno 256] No more mirrors to try.

在域名服务器配置中，添加一个8.8.8.8，就解决了：
# vi /etc/resolv.conf
# Generated by NetworkManager
nameserver 8.8.8.8
nameserver 211.155.23.88
nameserver 211.155.27.88
