这是一个比较老旧的话题，毕竟大家现在都使用Git（http://git-scm.com/），Git在分支、代码存储、冲突、速度方面的机制都更优秀。
那我们难道还有使用svn的场景？当然，比如对Git很陌生却要快速推进项目，再比如转换成本很高的场景。。。。总之技术上永远没有孰优孰劣，只是看使用的场景而已
进入正题，ssh服务器，切换到root用户，首先安装subversion:
apt-get install subversion
然后创建svn目录：
mkdir /home/svn
然后创建项目目录,xxxx为我们假定的目录名：
mkdir /home/svn/xxxx
cd /home/svn
chmod -R 777 xxxx
cd /home/svn
chmod -R 777 xxxx
然后就是初始化svn仓库：
svnadmin create /home/svn/xxxx
现在在项目目录里面会生成一堆文件和文件夹，至此项目基本搭建完成，下面进行权限部分
我们设定常用的场景是这样的，没有认证的用户只能读，认证之后的用户可以读写，认证是通过密码进行，let’s go:
cd /home/svn/xxxx/conf
vim svnserver.conf
vim svnserver.conf
然后注释以下3行，注意，开头不能有空格存在
anon-access = read //没有验证的用户只能读
auth-access = write //验证的用户能够读写
password-db = passwd //密码数据是当前目录下的passwd文件
然后我们就开始添加密码了
cd /home/svn/xxxx/conf
vim passwd
vim passwd
然后以如下格式添加用户名和密码：
username = passwd
还差最后一步，就是启动svn服务器：
svnserve -d -r /home/svn
-d 表示svnserver以“守护”进程模式运行
-r 指定文件系统的根位置，这样客户端不用输入全路径，就可以访问版本库
如：svn://youip/xxxx,eg: svn://192.168.1.7/xxxx
然后就可以开始使用啦
