Alwayson--使用证书创建高可用性组

--场景:

--有服务器SQLNode11,SQLNODE21,SQLNODE31三台在同一故障转移群集SQLNode01中

--的数据库服务器,安装SQL SERVER 2012 并配置启动alwayson高可用性组,服务使

--用localsystem运行,为SQLNode11上数据库DB1和DB2创建高可用性组,并将

--SQLNode21和SQLNode31加入到可用性组中。

--实现步骤概述：在各个节点上创建证书和端点并备份证书，使用备份依次在其他

--两个节点上创建登陆用户，在各个节点创建证书并为将连接权限赋予登陆用户，

--激活alwayson回话服务，在主节点SQLNode11上备份数据库并使用WITH NORECOVERY

--在从节点SQLNode21和SQLNode31上还原数据库，在主节点SQLNode11创建高可用性

--组，在从节点SQLNode21和SQLNode31上加入到可用性组，并在从节点SQLNode21

--和SQLNode31上将数据库添加到可用组中。
