一、配置YUM源

编辑以下文件

/etc/yum.repos.d/wandisco-svn.repo

添加一下内容

[WandiscoSVN]
name=Wandisco SVN Repo
baseurl=http://opensource.wandisco.com/centos/$releasever/svn-1.8/RPMS/$basearch/
enabled=1
gpgcheck=0

二、移除现有的Subversion版本

# yum remove subversion*

三、清除yun缓存并安装新版subversion

# yum clean all
# yum install subversion

# svn --version
