兩臺服務器，沒有域環境，如何配置SQL SERVER2008鏡像呢？
詳細過程如下：
SQL 2008配置有證書鏡像的步聚共有四步：
1. 配置出站連接：創建主祕鑰、證書和端點，備份證書並拷貝到另一臺服務器
2. 配置入站連接：分配登陸用戶、賦予登陸用戶connect本機端點的權限
3. 創建鏡像數據：備主數據庫，還原鏡像數據庫
4. 配置鏡像夥伴關係：順序：鏡像----主體
5. 測試鏡像：切換鏡像
運行環境：
主數據庫服務器： 192.168.1.2
鏡像數據庫服務器： 192.168.1.3
以下是測試的詳細腳本：
=============================================================
一．配置出站：配置完證書後，分別互存到各數據庫服務器的對應路徑，注意端口
=============================================================
配置HOST_2出站
USE master;
CREATE MASTER KEY ENCRYPTION BY PASSWORD = 'PassWord123';
GO
CREATE CERTIFICATE HOST_2_cert
WITH SUBJECT = 'HOST_2 certificate for database mirroring';
GO
CREATE ENDPOINT Endpoint_Mirroring
STATE = STARTED
AS TCP (
LISTENER_PORT=5023
, LISTENER_IP = ALL
)
FOR DATABASE_MIRRORING (
AUTHENTICATION = CERTIFICATE HOST_2_cert
, ENCRYPTION = REQUIRED ALGORITHM AES
, ROLE = ALL
);
GO
BACKUP CERTIFICATE HOST_2_cert TO FILE = 'D:\CERT\HOST_2_cert.cer';
GO
配置HOST_3出站
USE master;
CREATE MASTER KEY ENCRYPTION BY PASSWORD = 'PassWord123';
GO
CREATE CERTIFICATE HOST_3_cert
WITH SUBJECT = 'HOST_3 certificate for database mirroring';
GO
CREATE ENDPOINT Endpoint_Mirroring
STATE = STARTED
AS TCP (
LISTENER_PORT=5023
, LISTENER_IP = ALL
)
FOR DATABASE_MIRRORING (
AUTHENTICATION = CERTIFICATE HOST_3_cert
, ENCRYPTION = REQUIRED ALGORITHM AES
, ROLE = ALL
);
GO
BACKUP CERTIFICATE HOST_3_cert TO FILE = 'D:\CERT\HOST_3_cert.cer';
GO
=============================================================
二．入站鏡像連接配置服務器：注意證書的路徑，登錄賬戶的命名
=============================================================
HOST_2的入站配置：
USE master;
CREATE LOGIN HOST_3_LOGIN
WITH PASSWORD = 'mainone%123';
GO
USE master;
CREATE USER HOST_3_USER FOR LOGIN HOST_3_LOGIN;
GO
CREATE CERTIFICATE HOST_3_cert
AUTHORIZATION HOST_3_USER
FROM FILE = 'D:\CERT\HOST_3_cert.cer';
GO
GRANT CONNECT ON ENDPOINT::Endpoint_Mirroring TO HOST_3_LOGIN
GO
=============================================================
HOST_3的入站配置：
USE master;
CREATE LOGIN HOST_2_LOGIN
WITH PASSWORD = 'mainone%123';
GO
USE master;
CREATE USER HOST_2_USER FOR LOGIN HOST_2_LOGIN;
GO
CREATE CERTIFICATE HOST_2_cert
AUTHORIZATION HOST_2_USER
FROM FILE = 'D:\CERT\HOST_2_cert.cer';
GO
GRANT CONNECT ON ENDPOINT::Endpoint_Mirroring TO HOST_2_LOGIN
GO
=============================================================
三．配置數據庫：備份包括數據庫和日誌
=============================================================
備份主數據庫HOST_2：
USE master;
GO
ALTER DATABASE DBNAME
SET RECOVERY FULL;
GO
BACKUP DATABASE DBNAME
TO DISK = 'e:\DBNAME.bak'
WITH FORMAT
GO
BACKUP LOG DBNAME
TO DISK = 'e:\DBNAME_log.bak'
GO
還原鏡像數據庫HOST_3：
RESTORE DATABASE DBNAME
FROM DISK = 'E:\DBNAME.bak'
WITH NORECOVERY
GO
RESTORE LOG DBNAME
FROM DISK = 'E:\DBNAME_log.bak'
WITH FILE=1, NORECOVERY
GO
=============================================================
四．配置鏡像：順序：鏡像----主體
=============================================================
先執行HOST_3服務器：
ALTER DATABASE DBNAME
SET PARTNER = 'TCP://192.168.1.2:5023'
GO
再執行HOST_2服務器：
ALTER DATABASE DBNAME
SET PARTNER = 'TCP://192.168.1.3:5023' ,SAFETY OFF（此處添加“SAFETY OFF”會引起衝突，我在此處去除了）
GO
=============================================================
五．測試鏡像:在主數據庫上執行以下代碼可以強制將鏡像數據庫啓用爲主數據庫，可以查看數據同步的完整性。
=============================================================
主數據庫HOST_2執行:
USE master;
ALTER DATABASE DBNAME
SET PARTNER FAILOVER
GO
2死機之後，在3 上執行 ：強行將鏡像服務器提升爲主服務器：
ALTER DATABASE DBNAME
SET PARTNER FORCE_SERVICE_ALLOW_DATA_LOSS
