部署说明:
以下部署基于工作组环境、不用证书、启动账号为Users组成员、各节点位于同一网段。
前期环境准备参考之前的文章:

Part7:创建AG
SQL Server 2016 AlwaysOn AG有很多提升,令我影响深刻的是日志吞吐量的提升和redo的提升。这里讲介绍它的另一项关键提升,也就是这个配置选项:Database Level Health Detection。
SQL Server 2016使用数据库健康检测增强了AlwaysOn健康诊断。如果你的AG的该选项被勾选,而其中某个数据库变为非ONLINE状态,那么整个AG将会自动故障转移。
Part8:检查AG状态
Part9:测试Server01宕机后
Part10:测试Server02恢复后
