sql server 2008 数据库镜像(二)---镜像实战

　　通过证书方式创建数据库镜像
　　主数据库代码：

Code
USE


--创建数据库主密钥。
IF EXISTS(SELECT * FROM sys.databases WHERE name='master' and is_master_key_encrypted_by_server=1)   
    --drop master key;
    OPEN MASTER KEY DECRYPTION BY PASSWORD='123456789';
ELSE
    create MASTER KEY ENCRYPTION BY PASSWORD='123456789';
GO

SELECT * FROM sys.key_encryptions;
go

--向数据库中添加证书。
IF EXISTS(select * from sys.database_mirroring_endpoints WHERE name='Endpoint_Mirroring')
    DROP ENDPOINT Endpoint_Mirroring
GO

IF EXISTS(select * from sys.certificates WHERE name='HOST_A_cert')
    DROP CERTIFICATE HOST_A_cert;
GO

CREATE CERTIFICATE HOST_A_cert WITH SUBJECT = 'HOST_A certificate',
    START_DATE = '2008-01-01';
GO

SELECT * FROM sys.certificates;
GO

--创建数据库端点
IF EXISTS(SELECT * FROM sys.database_mirroring_endpoints WHERE name='Endpoint_Mirroring')
    DROP ENDPOINT Endpoint_Mirroring;
GO

CREATE ENDPOINT Endpoint_Mirroring STATE=STARTED
    AS TCP ( LISTENER_PORT=5022 ,
      LISTENER_IP = ALL )
    FOR DATABASE_MIRRORING( AUTHENTICATION = CERTIFICATE HOST_A_cert ,
      ENCRYPTION = REQUIRED ALGORITHM RC4 ,
      ROLE = PARTNER );
GO


SELECT * FROM sys.database_mirroring_endpoints;
GO





--备份证书
BACKUP CERTIFICATE HOST_A_cert TO FILE = 'D:\MIRROR\HOST_A_cert.cer';
GO

--在服务器之间手动拷贝证书,保证每个服务只器都有所有证书


--创建用户,用于访问MIRROR
IF EXISTS(select * from sys.certificates WHERE name='HOST_B_cert')
    DROP CERTIFICATE HOST_B_cert
GO

IF EXISTS(select * from sys.sql_logins WHERE name='HOST_B_login')
    DROP LOGIN HOST_B_login
GO

IF EXISTS(select * from sys.database_principals WHEREname='HOST_B_user')
    DROP USER HOST_B_user
GO

create LOGIN HOST_B_login WITH PASSWORD = '123456789';
create USER HOST_B_user FOR LOGIN HOST_B_login;
create CERTIFICATE
    HOST_B_cert AUTHORIZATION HOST_B_user FROM FILE = 'D:\MIRROR\HOST_B_cert.cer';
GO

GRANT CONNECT ON ENDPOINT::Endpoint_Mirroring TO ;
GO

--创建用户,用于访问WITNESS
IF EXISTS(select * from sys.certificates WHERE name='HOST_C_cert')
    DROP CERTIFICATE HOST_C_cert
GO

IF EXISTS(select * from sys.sql_logins WHERE name='HOST_C_login')

create CERTIFICATE
    HOST_C_cert AUTHORIZATION HOST_C_user FROM FILE = 'D:\MIRROR\HOST_C_cert.cer';
GO

GRANT CONNECT ON ENDPOINT::Endpoint_Mirroring TO ;
GO

--拷贝用户
SELECT , FROM sys.database_principals WHERE ='BetterDev'

--备份数据库



--设置伙伴
ALTER DATABASE northwind SET PARTNER='TCP://192.168.1.116:5022';
GO
--设置见证
ALTER DATABASE NORTHWIND SET WITNESS='TCP://192.168.1.117:5022';
GO
--设置安全选项
ALTER DATABASE NORTHWIND SET SAFETY FULL
