SQL 2016 AlwaysOn 无域AlwaysOn配置要点

环境准备：

（1）操作系统：Windows Server 2016 Datacenter

（2）SQL Server 2016

配置SQL 2016 AlwaysOn 要点

1，因为没有域所以需要在”计算机属性“添加计算机的DNS后缀。如后缀是: kk1.com

2，非账户Administrator(是管理员组的新账号也不行），需在运行下列命令

注意：如果登陆Windows Server 2016服务器的账户不是Administrator，需要先以管理员方式运行PowerShell，执行下面的命令：

new-itemproperty -path HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System -Name LocalAccountTokenFilterPolicy -Value 1

3，关闭各个服务器的防火墙。

4，hosts文件路径：C:\Windows\System32\drivers\etc，用名称和IP对应，防止用名称无法对应具体服务器

192.168.63.79  WIN-VE5LU48EGRI.kk1.com
192.168.63.81  WIN-7BEPP8D305E.kk1.com
192.168.63.83  WIN-QF3PITJO4SU.kk1.com
192.168.63.79  WIN-VE5LU48EGRI
192.168.63.81  WIN-7BEPP8D305E
192.168.63.83  WIN-QF3PITJO4SU

5，既然节点没有加入域，那么就不能用域认证，只能用证书认证，因此需要创建证书和端点，下面是2个服务器，3个以上服务器，要在各服务器上创建其他节点的证书

--节点一上执行：创建主密钥/证书/端点，备份证书。 
USE master; 
GO

CREATE MASTER KEY ENCRYPTION BY PASSWORD = 'JFAlwaysOnShare2016'; ----密码
GO

CREATE CERTIFICATE Cert_DB01 
WITH SUBJECT = 'Cert_DB01', 
START_DATE = '2017-12-01',EXPIRY_DATE = '2099-12-31'; 
GO

BACKUP CERTIFICATE Cert_DB01 
TO FILE = '\\JF-SQLDB01\SQLAlwaysOnShare\Cert_DB01.cer'; 
GO

CREATE ENDPOINT [SQLAG_Endpoint] 
AUTHORIZATION [JF-SQLDB01\administrator] 
STATE=STARTED 
AS TCP (LISTENER_PORT = 5022, LISTENER_IP = ALL) 
FOR DATA_MIRRORING 
(ROLE = ALL,AUTHENTICATION = CERTIFICATE Cert_DB01, ENCRYPTION = REQUIRED ALGORITHM AES)
GO

 
--节点二上执行：创建主密钥/证书，备份证书。 
USE master; 
GO 
CREATE MASTER KEY ENCRYPTION BY PASSWORD = 'JFAlwaysOnShare2016'; 
GO

CREATE CERTIFICATE Cert_DB02 
WITH SUBJECT = 'Cert_DB02', 
START_DATE = '2017-12-01',EXPIRY_DATE = '2099-12-31'; 
GO

BACKUP CERTIFICATE Cert_DB02 
TO FILE = '\\JF-SQLDB01\SQLAlwaysOnShare\Cert_DB02.cer'; 
GO

CREATE ENDPOINT [SQLAG_Endpoint] 
AUTHORIZATION [JF-SQLDB02\administrator] 
STATE=STARTED 
AS TCP (LISTENER_PORT = 5022, LISTENER_IP = ALL) 
FOR DATA_MIRRORING 
(ROLE = ALL,AUTHENTICATION = CERTIFICATE Cert_DB02, ENCRYPTION = REQUIRED ALGORITHM AES)
GO

--节点一上执行：创建节点二的证书 
USE master; 
GO 
CREATE CERTIFICATE Cert_DB02 
FROM FILE = '\\JF-SQLDB01\SQLAlwaysOnShare\Cert_DB02.cer'; 
GO

--节点二上执行：创建节点一的证书 
USE master; 
GO 
CREATE CERTIFICATE Cert_DB01 
FROM FILE = '\\JF-SQLDB01\SQLAlwaysOnShare\Cert_DB01.cer'; 
GO

6，配置好故障转移后，关闭故障转移群集，再打开不自动显示群集，这时需要，用名称：如 JF-AlwaysOn1.kk1.com，群集名称是： JF-AlwaysOn1 ，连接时候要加上DNS后缀
