安装svn的时候，发现报错说一个地址无法訪问。

# 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server配置中。加入一个8.8.8.8，就攻克了：

# vi /etc/resolv.conf

# Generated by NetworkManager
nameserver 8.8.8.8
nameserver 211.155.23.88
nameserver 211.155.27.88
