1. Ubuntu PC一台，最好是最新的Ubuntu稳定版本

2. 执行以下命令安装subversion：

sudo apt-get update
sudo apt-get install subversion

3. 假设代码svn仓库的根路径定为 /home/svnroot，执行以下命令新建目录：

sudo mkdir /home/svnroot

4. 新建一个代码仓库，假设仓库名为：example

cd /home/svnroot
sudo svnadmin create example

此命令执行完成后会在 /home/svnroot 下多出来一个名为example的目录，这就是example代码仓库了。

5. 编辑example仓库的访问权限

即：修改 /home/svnroot/example/conf下的三个文件：authz passwd svnserve.conf

其中：

passwd 中保存了用户名和密码

authz 中保存了用户组定义及各目录的访问权限定义

svnserve.conf 中保存了本代码仓库使用的配置（是否允许匿名用户？指定用户名和密码数据库...）

这里给出一个典型的配置：

passwd实例：

[users]
xiaoming = 1111
xiaowang = 2222
xiaoli = 3333
laowang = 4444
shuangshuang = 5555
dashi = 6666

authz实例（admin可以读写所有目录，dev能读写branch，dev只读trunk/tag）：

[aliases]
# joe = /C=XZ/ST=Dessert/L=Snake City/O=Snake Oil, Ltd./OU=Research Institute/CN=Joe Average
[groups]
admin = xiaoli
dev = laowang,shuangshuang,dashi,xiaowang,xiaoming
[/]
@admin = rw
@dev = r
[/trunk]
@admin = rw
@dev = r
[/tag]
@admin = rw
@dev = r
[/branch]
@admin = rw
@dev = rw

svnserve.conf实例（关闭匿名访问，指定用户数据库和鉴权数据库）：

### This file controls the configuration of the svnserve daemon, if you
### use it to allow access to this repository. (If you only allow
### access through http: and/or file: URLs, then this file is
### irrelevant.)
### Visit http://subversion.tigris.org/ for more information.
[general]
### These options control access to the repository for unauthenticated
### and authenticated users. Valid values are "write", "read",
### and "none". The sample settings below are the defaults.
anon-access = none
auth-access = write
### The password-db option controls the location of the password
### database file. Unless you specify a path starting with a /,
### the file's location is relative to the directory containing
### this configuration file.
### If SASL is enabled (see below), this file will NOT be used.
### Uncomment the line below to use the default password file.
password-db = passwd
### The authz-db option controls the location of the authorization
### rules for path-based access control. Unless you specify a path
### starting with a /, the file's location is relative to the the
### directory containing this file. If you don't specify an
### authz-db, no path-based access control is done.
### Uncomment the line below to use the default authorization file.
authz-db = authz
### This option specifies the authentication realm of the repository.
### If two repositories have the same authentication realm, they should
### have the same password database, and vice versa. The default realm
### is repository's uuid.
# realm = My First Repository
[sasl]
### This option specifies whether you want to use the Cyrus SASL
### library for authentication. Default is false.
### This section will be ignored if svnserve is not built with Cyrus
### SASL support; to check, run 'svnserve --version' and look for a line
### reading 'Cyrus SASL authentication is available.'
# use-sasl = true
### These options specify the desired strength of the security layer
### that you want SASL to provide. 0 means no encryption, 1 means
### integrity-checking only, values larger than 1 are correlated
### to the effective key length for encryption (e.g. 128 means 128-bit
### encryption). The values below are the defaults.
# min-encryption = 0
# max-encryption = 256

6. 添加svn服务为系统自启动项目

- 创建svnd.sh ，内容如下

#!/bin/bash
svnserve -d -r /home/svnroot

将这个文件放在 /etc/init.d/svnd.sh

这个脚本的功能：启动svn服务，只有在启动服务后，外部的机器才能通过各种svn工具来访问svn服务器。

- 添加可执行权限

sudo chmod a+x /etc/init.d/svnd.sh

- 编辑 rc.local

vim /etc/rc.local

在exit 0之前，加上
/etc/init.d/svnd.sh

- 重启服务器，然后执行命令：

ps -e | grep svnserve

从命令结果来检查svn服务是否已经自动的随系统启动。
