最近研究Windowssvn的备份机制,结合网上的文章,分享下完成的svndump的备份脚本,记录一下svnsync的使用方法。

不多说了,直接贴脚本。

2.svnsync异地备份记录
这里先说一下svnsync的用法,在讲一下备份搭建过程,本文中省略部分建库和建用户的具体步骤。
svnsyncinit--trust-server-cert--source-usernameARG--source-passwordARG--sync-usernameARG--sync-passwordARGDEST_URLSOURCE_URL
svnsyncsync--trust-server-cert--non-interactive--source-usernameARG--source-passwordARG--sync-usernameARG--sync-passwordARGDEST_UR
注:如果svnsync版本不支持source-username、sync-username分别设置两个库的用户和口令,可以用--username、--password设置源库和备份库的用户和口令,但是两个库的用户和口令必须相同。
--trust-server-cert信任服务器证书(如https自签名证书)
--source-username源库用户名
--sync-username镜像库用户名
ARGDEST_URL、SOURCE_URL镜像库地址,源库地址
--non-interactive非交互模式
下面是搭建过程
源库:https://192.168.1.2:443/svn/lsgl
服务器路径e:\svn\lsgl
同步用户syncuser:passwd
镜像库:https://192.168.1.3:443/svn/lsgl
服务器路径d:\svn\lsgl
同步用户syncuser:passwd
1)如果源库不存在,请新建源库,这里不做介绍了,然后新建用户syncuser,并授予读取权限。
以下在镜像服务器:
2)新建一个新库
mkdird:\svn\lsgl
cdd:\svn\lsgl
svnadmincreate
3)在镜像库新建用户syncuser,并授予读写权限。
4)新建文件d:\svn\lsgl\hooks\pre-revprop-change.bat,只允许同步用户修改镜像库属性,内容如下:
IF "%3" == "syncuser" exit 0 echo"Only syncuser may change revision properties">&2 exit 1
5)新建d:\svn\lsgl\hooks\start-commit.bat,只允许同步用户提交新版本,内容如下:
IF "%3" == "syncuser" exit 0 echo"Only syncuser may commit new revisions">&2 exit 1
6)执行命令
svnsyncinit--usernamesyncuser--passwordpasswdhttps://192.168.1.3:443/svn/lsglhttps://192.168.1.2:443/svn/lsgl
以下在源库服务器执行:
7)新建e:\svn\lsgl\hooks\post-commit.bat,实时备份数据,内容如下。
svnsync--trust-server-cert--non-interactive--usernamesyncuser--passwordpasswdsynchttps://192.168.1.3:443/svn/lsgl
至此完成。
还有些话要说,在搭建备份库的时候,新建库后直接开启同步,从r0同步至head;在网上看到新建库后,load数据再进行同步,将方法记录在下面,笔者并没有验证。
先准备源库的dump文件。
svnadmindumpe:\svn\lsgl>source-lsgl.dump
将上面的第6)步提换如下:
svnadminloadd:\svn\lsgl<source-lsgl.dump
然后手动设置镜像库的属性
svnpropset--revprop-r0svn:sync-from-uuid源库的UUID
svnpropset--revprop-r0svn:sync-last-merged-revdump文件的最新版本https://192.168.1.3:443/svn/lsgl
svnpropset--revprop-r0svn:sync-from-urlhttps://192.168.1.3:443/svn/lsgl。
还有话要说,如何切换备库:
这个简单,讲备库上的bat文件删除,设置好用户和权限后就可以访问了。
最后还有话要说,操作的时候由于命令行用户名输入错误,在提示输入口令时ctrl+c强退了,导致镜像库锁定,出现“Failedtogetlockondestinationreposcurrentlyheldby。。。”的错误,使用下面的命令处理错误。
svnpropdelsvn:sync-lock--revprop-r0https://10.204.3.11/svn/lsgl/
pub_svnserve.conf的 pub_authz.conf的配置文件有非法字符的原因引起,需要查找pub_authz.conf提的非法内容比如多余的空格删除或直接将pub_authz.conf
