CentOS/RHEL yum 安装的 subversion 是 1.6.11 版本，连VisualSVN服务器时会有"Key usage violation"的错误
将subversion升级到最新版可解决该问题
1.添加源
vim /etc/yum.repos.d/wandisco-svn.repo
[WandiscoSVN]
name=Wandisco SVN Repo
baseurl=http://opensource.wandisco.com/centos/$releasever/svn-1.8/RPMS/$basearch/
enabled=1
gpgcheck=0
2、yum删除旧的包
yum remove subversion*
3.安装新的包
yum clean all
yum install subversion
