CentOS6.6 默认yum源安装的subversion版本为1.6.11
1.创建一个yum repo文件
vi /etc/yum.repos.d/wandisco-svn.repo
2.添加如下内容
[WandiscoSVN]
name=Wandisco SVN Repo
baseurl=http://opensource.wandisco.com/centos/$releasever/svn-1.8/RPMS/$basearch/
enabled=1
gpgcheck=0
3.检查是否有subversion1.8
yum list | grep subversion | grep 1.8
yum list | grep subversion | grep 1.8
4.删除现有subversion1.6
rpm -qa | grep subversion | awk '{print $1;}' | xargs yum -y remove
5.安装subversion1.8
yum clean all && yum -y install subversion
6.注：如有下图报错可能是因为你在CentOS6上配置了一个CentOS7的Epel repository
