系统默认的svn不支持sasl加密。若svn服务器开启sasl加密的话将报错：Cannot negotiate authentication mechanism。需重新编译安装。

下载

subversion官网下载 subversion要先安装apr和apr-util： apr和apr-util下载

安装

apr编译安装：

./configure
make
sudo make install

apr-util编译安装：

./configure --with-apr=/usr/local/apr
make
sudo make install

subversion编译安装:

./configure --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr
make
sudo make install

安装完之后svn命令要做一个软链接:

sudo ln -s /usr/local/bin/svn /usr/bin/svn

查看版本:

$ svn --version
