# 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 http://hostname/svn/
# Note, a literal /svn should NOT exist in your document root.

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 BasicAuthName "Subversion Repository"AuthUserFile /etc/apache2/dav_svn.passwd# To enable authorization via mod_authz_svn (enable that module separately):<IfModule mod_authz_svn.c>AuthzSVNAccessFile /etc/apache2/dav_svn.authz</IfModule># The following three lines allow anonymous read, but make# committers authenticate themselves.

Adding password for user wwl
sudo htpasswd /etc/apache2/dav_svn.passwd apache
sudo htpasswd /etc/apache2/dav_svn.passwd test1
sudo htpasswd /etc/apache2/dav_svn.passwd test2

sudo vi /etc/apache2/dav_svn.authz

[groups]
admin = wwl
CM = apache
test = test1,test2[/]
* =
@admin = rw
@CM = r[repo1:/]
* =
@CM = rw
@test = r[repo1:/branches]
@test = rw
[repo1:/trunk]
test2 = rw

[groups]代表组定义：“组名 = 用户1,用户2...”；[repo1:/]代表repo1配置库，repo1是配置库名称；[repo1:/trunk]代表repo1配置库下/trunk目录；@ 符号，则表示这是个群组权限设置；@ admin = rw代表admin 这个组的所有用户有读写权限test2 = rw代表test2这个用户对trunk有读写权限PS：注意svn的权限继承关系

8.修改apache启动用户为apache：

sudo vi /etc/apache2/envvars

export APACHE_RUN_USER=apache
export APACHE_RUN_GROUP=apache

9.授权svn.authz要加载mod_authz_svn.so 在目录 /etc/apache2/mods-enabled 下创建软链接到 ../mods-available/authz_svn.load：
