部署SQL Server 2016基于工作组的AlwaysOn AG
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：

Part4:创建AG内数据库的完整备份
BACKUP DATABASE Chapter5App1Customers TO DISK = N'C:\Backups\Chapter5App1Customers.bak' WITH NAME = N'Chapter5App1Customers-Full Database Backup' ; GO BACKUP DATABASE Chapter5App1Sales TO DISK = N'C:\Backups\Chapter5App1Sales.bak' WITH NAME = N'Chapter5App1Sales-Full Database Backup' ; GO
Part5:将备份在AG内的其他副本上恢复为NORECOVERY
Part6:将启动账号添加到Logins
--提前创建端点
USE [master]
GO
CREATE ENDPOINT [Hadr_endpoint]
STATE=STARTED
AS TCP (LISTENER_PORT = 5022, LISTENER_IP = ALL)
FOR DATA_MIRRORING (ROLE = ALL, AUTHENTICATION = WINDOWS NEGOTIATE
, ENCRYPTION = REQUIRED ALGORITHM AES)
GO
DECLARE @Server sysname,
@HostName sysname,
@Login sysname,
@SQL nvarchar(max)
;
--获取实例名
SET @Server = CAST(SERVERPROPERTY('ServerName') AS sysname);
--获取机器名（远程执行时HOST_NAME()函数不代表远程主机）
IF CHARINDEX('\\',@Server,1) <> 0
SET @HostName = SUBSTRING(@Server,1,CHARINDEX('\\',@Server,1)-1);
ELSE
SET @HostName = @Server;
--用到SQL Server Database Engine服务启动账号
SET @Login = @HostName + '\SQLService';
IF NOT EXISTS(SELECT name FROM sys.syslogins WHERE isntuser=1 AND name = @Login)
BEGIN
--SELECT @Login
EXEC sp_grantlogin @Login;
--EXEC sp_addsrvrolemember @Login, 'sysadmin';
--端点访问授权
SET @SQL = N'GRANT CONNECT ON ENDPOINT::[Hadr_endpoint] TO [' + @Login + ']';
--SELECT @SQL
EXEC sp_executesql @SQL;
ENDPart7: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
