subversion 简介
Subversion是一个自由开源的版本控制系统。在Subversion管理下，文件和目录可以超越时空。
Subversion将文件存放在中心版本库里，这个版本库很像一个普通的文件服务器，不同的是，它可以记录每一次文件和目录的修改情况，这样就可以借此将数据恢复到以前的版本，并可以查看数据的更改细节。正因为如此，许多人将版本控制系统当作一种神奇的“时间机器”。

subversion 安装
[root@linuxprobe~]# yum -y install subversion
创建源仓库，以“/var/svn/repos/project”为例
[root@linuxprobe ~]# mkdir -p /var/svn/repos/project
[root@linuxprobe ~]# svnadmin create /var/svn/repos/project # 创建源仓库
[root@linuxprobe ~]# svn mkdir file:///var/svn/repos/project/trunk -m "create"
Committed revision 1.
[root@linuxprobe ~]# svn mkdir file:///var/svn/repos/project/branches -m "create" # 创建分支
Committed revision 2.
[root@linuxprobe ~]# svn mkdir file:///var/svn/repos/project/tags -m "create" # 创建标签
Committed revision 3.
导入已存在的代码文件到SVN仓库，导入/home/project目录的文件
[root@linuxprobe ~]# ll /home/project/

Adding /home/project/index.html
Adding /home/project/index.go
Adding /home/project/index.php
Adding /home/project/index.py
Adding /home/project/info.php

启动svnserver，svnserve监听TCP 3690，防火墙开启端口通信
# svn server 端
[root@linuxprobe ~]# systemctl start svnserve
# svn client 端
[root@vdevops ~]# yum -y install svn
[root@vdevops ~]# svn list svn://linuxprobe.org/repos/project
branches/
tags/
trunk/
# 导出代码到本地
[root@vdevops ~]# svn checkout svn://linuxprobe.org/repos/project
A project/tags
A project/trunk
A project/trunk/info.php
A project/trunk/index.html
A project/trunk/index.go
A project/trunk/index.php
A project/trunk/index.py
A project/branches
Checked out revision 4.
如果没有启动svnserve，通过端口无法连接到svn server，可以通过ssh的方式连接到svn server
# svn server 端
[root@linuxprobe ~]# systemctl stop svnserve
# svn client端
[root@vdevops ~]# svn list svn+ssh://root@linuxprobe.org/var/svn/repos/project
root@linuxprobe.org's password:

subversion 访问控制
设置访问控制“/var/svn/repos/project”
[root@linuxprobe ~]# vi /var/svn/repos/project/conf/svnserve.conf
# line 9: add (prohibit anonymous access)
[general]
anon-access = none
# line 28: uncomment
password-db = passwd
# line 35: uncomment
authz-db = authz
[root@linuxprobe ~]# vi /var/svn/repos/project/conf/passwd
# define username and password for this repository
[users]
shaon= password
wang = password
devops = password
[root@linuxprobe ~]# vi /var/svn/repos/project/conf/authz
# define groups and users
[groups]
developer = devops,wang
# allow read/write on document root for developer group
[/]
@developer = rw
# allow read on trunk folder for fedora user
[/trunk]
shaon = r
svn client 客户端测试
[root@vdevops trunk]# svn --username shaon list svn://linuxprobe.org/repos/project/trunk
Authentication realm: <svn://linuxprobe.org:3690> LinuxProbe Repository
Password for 'shaon':
-----------------------------------------------------------------------
ATTENTION! Your password for authentication realm:
<svn://linuxprobe.org:3690> LinuxProbe Repository # 仓库名称
can only be stored to disk unencrypted! You are advised to configure
your system so that Subversion can store passwords encrypted, if
possible. See the documentation for details.
You can avoid future appearances of this warning by setting the value
of the 'store-plaintext-passwords' option to either 'yes' or 'no' in
'/root/.subversion/servers'.

Store password unencrypted (yes/no)? yes #记住密码
