部署SQL Server 2016基于工作組的AlwaysOn AG
部署說明：
以下部署基于工作組環境、不用證書、啟動賬號為Users組成員、各節點位于同一網段。
前期環境準備參考之前的文章：

GO
DECLARE @Server sysname,
@HostName sysname,
@Login sysname,
@SQL nvarchar(max)
;
--獲取實例名
SET @Server = CAST(SERVERPROPERTY('ServerName') AS sysname);
--獲取機器名（遠程執行時HOST_NAME()函數不代表遠程主機）
IF CHARINDEX('\\',@Server,1) <> 0
SET @HostName = SUBSTRING(@Server,1,CHARINDEX('\\',@Server,1)-1);
ELSE
SET @HostName = @Server;
--用到SQL Server Database Engine服務啟動賬號
SET @Login = @HostName + '\SQLService';
IF NOT EXISTS(SELECT name FROM sys.syslogins WHERE isntuser=1 AND name = @Login)
BEGIN

--SELECT @SQL
EXEC sp_executesql @SQL;
ENDPart7:創建AG
SQL Server 2016 AlwaysOn AG有很多提升，令我影響深刻的是日志吞吐量的提升和redo的提升。這里講介紹它的另一項關鍵提升，也就是這個配置選項：Database Level Health Detection。
SQL Server 2016使用數據庫健康檢測增強了AlwaysOn健康診斷。如果你的AG的該選項被勾選，而其中某個數據庫變為非ONLINE狀態，那么整個AG將會自動故障轉移。
Part8:檢查AG狀態
Part9:測試Server01宕機后
Part10:測試Server02恢復后
