linux svn服务器搭建、客户端操作、备份与恢复 Subversion(SVN)是一个开源的版本控制系，管理着随时间改变的数据。这些数据放置在一个中央资料档案库中，这个档案库很像一个普通的文件服务器，它会记住每一次文件的变动，这样就可以把档案恢复到旧的版本,或是浏览文件的变动历史。

linux svn备份与恢复
一、linux svn服务器部署
1、安装svn
[root@yang~]#yum install -y subversion
[root@yang~]#svnserve--version
svnserve,version 1.6.11 (r934486)
2、创建SVN版本库
[root@yang~]# mkdir /data/svn
[root@yang~]# svnadmin create /data/svn/project
[root@yangproject]# ls /data/svn/project/
conf db format hooks locks README.txt
3、配置SVN
[root@yangproject]# cd /data/svn/project/conf/
[root@yangconf]# ls
authz passwdsvnserve.conf
文件说明：
1）svnserve.conf： svn服务配置文件下。
2）passwd： 用户名密码文件。
3）authz： svn权限配置文件。
svnserve.conf文件
该文件配置项分为以下5项：
anon-access： 控制非鉴权用户访问版本库的权限。
auth-access：控制鉴权用户访问版本库的权限。
password-db： 指定用户名口令文件名。
authz-db：指定权限配置文件名，通过该文件可以实现以路径为基础的访问控制。
realm： 指定版本库的认证域，即在登录时提示的认证域名称。若两个版本库的认证域相同，建议使用相同的用户名口令数据文件
配置如下：
[root@yangconf]# grep -E "anon-access =|auth-access =|password-db =|authz-db =|realm=" svnserve.conf
anon-access = none
auth-access = write
password-db = passwd
authz-db = authz
realm = /data/svn/project
passwd文件
作用是配置用户名和密码
[root@yangconf]# cat passwd
yangyun= yangyunpasswd
test = testpasswd
authz文件
配置用户访问权限
[root@yangconf]# cat authz |grep -v '#'
[aliases]
[groups]
project_w=yangyun
project_r=test
[/]
project_w=rw
project_r=r
4、启动svn服务
[root@yangconf]# svnserve -d -r /data/svn
5、初始化svn数据
[root@yangdjango]# svn import mysite file:///data/svn/project/ -m 'initial import'
将会拷贝目录mysite到版本库的project下
[root@yangdjango]# svn list file:///data/svn/project
manage.py
mysite/
static/
templates/
web02/
在导入之后，原来的目录树并没有转化成工作拷贝，为了开始工作，还是需要运行svn checkout导出一个工作拷贝。
二、linux svn客户端命令操作
1、将文件checkout到本地目录
svn checkout path（path是服务器上的目录）
简写：svn co
例：
svn co svn://115.28.24.178/project --username=yangyun --password=yangyunpasswd
#指定版本的文件
svn co svn://115.28.24.178/project --username=yangyun --password=yangyunpasswd-r 5
2、往本地版本库中添加新的文件
svn add file #此命令得在checkout出来的路径里才能操作
例如：
cp /root/123.txt./
svn add 123.txt #把123.txt加入到本地库中
A 123.txt
3、将改动的文件提交到版本库
svn commit -m "LogMessage" [-N] [--no-unlock] PATH(如果选择了保锁，就使用--no-unlock开关)
简写：svn ci
例：
svn commit 123.txt -m 'add 123.txt' #只提交123.txt
svn commit -m 'add 123.txt' #默认提交当前目录下的所以文件
svn commit *.txt -m 'add 123.txt' #也可以正则匹配文件提交
4、加锁/解锁
svn lock -m "Loc 说明： centos 6.5mysql 5.5.37 mha4mysql-manager-0.55 mha4mysql-node-0.54 manager 192.168.1.1 配置mysql主从 server-id = 1 db2,db3忽略 db1主 db2备 db3从 db1主 db2备 和 db3从 配置略 安装mysql-MHA db1主 db2备 db3从 manager #这两个yum没有安装上 perl-Log-Dispatch perl-Parallel-ForkManager rpm -ivh perl-Mail-Sender-0.8.16-1.el6.rf.noarch.rpm 配置mysql-MHA tar -xzf mha4mysql-manager-0.55.tar.gz mkdir -p /usr/local/mha/scripts #验证ssh通讯 #验证mysql复制
