或许现在大多数高级程序员都用github来做代码管理工具，但是还有很多公司考虑到便于实施和人员接受能力的问题，还是会选择svn作为代码版本管理工具，下面介绍一下如何基于Apache搭建SVN版本库。
安装svn相关模块
Ubuntu下安装命令
sudo apt-get install subversion libapache2-svn
安装成功后截图
配置svn版本库
创建svn根目录
mkdir -p /home/svn
创建所需要的版本库
cd /home/svn/
sudo svnadmin create 版本库的名字
修改版本库目录的权限
因为是通过apache访问svn，所以目录的属主均为www-data即可
sudo chown -R www-data.www-data 版本库名字
配置Apache
修改apache基于svn模块的配置文件
sudo vim /etc/apache2/mods-available/dav_svn.conf
修改后配置文件内容如下
# dav_svn.conf - Example Subversion/Apache configuration
#
# For details and further options see the Apache user manual and
# the Subversion book.
#
# NOTE: for a setup with multiple vhosts, you will want to do this
# configuration in /etc/apache2/sites-available/*, not here.
# <Location URL> ... </Location>
# URL controls how the repository appears to the outside world.
# In this example clients access the repository as
# Note, a literal /svn should NOT exist in your document root.
<Location /svn>
# Uncomment this to enable the repository
DAV svn
# Set this to the path to your repository
# SVNPath /home/svn
# Alternatively, use SVNParentPath if you have multiple repositories under
# under a single directory (/var/lib/svn/repo1, /var/lib/svn/repo2, ...).
# You need either SVNPath and SVNParentPath, but not both.
SVNListParentPath on
SVNParentPath /home/svn
# Access control is done at 3 levels: (1) Apache authentication, via
# any of several methods. A "Basic Auth" section is commented out
# below. (2) Apache <Limit> and <LimitExcept>, also commented out
# below. (3) mod_authz_svn is a svn-specific authorization module
# which offers fine-grained read/write access control for paths
# within a repository. (The first two layers are coarse-grained; you
# can only enable/disable access to an entire repository.) Note that
# mod_authz_svn is noticeably slower than the other two layers, so if
# you don't need the fine-grained control, don't configure it.
# Basic Authentication is repository-wide. It is not secure unless
# you are using https. See the 'htpasswd' command to create and
# manage the password file - and the documentation for the
# 'auth_basic' and 'authn_file' modules, which you will need for this
# (enable them with 'a2enmod').
AuthType Basic
AuthName "Subversion Repository"
AuthUserFile /etc/apache2/dav_svn.passwd
# To enable authorization via mod_authz_svn
AuthzSVNAccessFile /etc/apache2/dav_svn.authz
# The following three lines allow anonymous read, but make
# committers authenticate themselves. It requires the 'authz_user'
# module (enable it with 'a2enmod').
#<LimitExcept GET PROPFIND OPTIONS REPORT>
Require valid-user
#</LimitExcept>
</Location>
注意：
<Location /svn>与</Location>成对出现
DAV svn开启DAV模块支持
SVNPath与SVNParentPath二选其一，不能同时出现，建议使用SVNParentPath，这样可以在SVN的根目录下创建多个svn版本库
开启BASIC认证
多读一下英文注释，很简单的
