Sqlserver2008镜像功能可以保障数据库的高可用性。数据库镜像维护着数据库的两个副本,这两个副本必须分别放置在不同的SQL Server数据库实例中。可以用两台服务器也可以用一台服务器的不同实例来承载,但实例必须具有不同的数据镜像端口。其中一台上的数据库用于客户端访问,充当“主体服务器”角色;而另一台则根据镜像会话的配置和状态,充当热备份服务器,即“镜像服务器角色”,当主体服务器发生故障时,可以切换到备份服务器来充当主体服务器的功能,切换的过程可以使手动,也可以自动切换,自动切换必须添加一个“见证服务器角色”,用于监视主体服务是否支持数据库服务自动故障转移。

主体服务器与镜像服务器之间同步的原理在此不在描述,请参见微软官网:http://msdn.microsoft.com/zh-cn/library/ms189852.aspx。

设置步骤

1、环境准备

  安装数据库服务Sqlserver2008R2,必须具有相同的版本。

  安装后开启数据库服务和代理服务。

  防火墙开启数据库端口1433和服务端口5022。

  镜像服务器IP:    10.101.84.74

  见证服务器IP:    10.102.7.185

2、修改服务器Host文件

  分别打开修改这三个服务器的HOST文件,添加以下指向:

  10.102.12.106        iZ27mnaky5m8Z
  10.101.83.74          iZ274pad4siqZab
  10.102.7.185          iZ27gj5a4e7pZcd

  后面服务器对应的机器名

3、备份以及恢复数据库

  目标数据库恢复模式必须为“完整”。

  备份数据库和备份日志选择同一文件。

  在镜像服务器上进行恢复时,还原选项选择“覆盖现有数据库” 恢复状态选择“不对数据库选择任何操作.......”
