使用TDE进行数据库镜像

我需要镜像一些数据库，并在它们上使用透明数据加密（TDE），因为我们的数据必须在“静止”时进行加密。

我在主体和镜像上都设置了TDE。当我设置两个数据库的镜像时，我遇到了这个问题。由于我使用的是TDE，所以我不知道通过gui设置镜像的方法，因此我不得不使用t-sql来完成工作。

以下是我在镜像服务器上使用的代码

--Restore the full backup to the mirrored mdf and ldf
OPEN MASTER KEY DECRYPTION BY PASSWORD = '1Password'
RESTORE DATABASE TDE
   FROM disk = '\\SERVERNAME\SQL_Stuff\Backup\TDE_FULL.bak'
      WITH NORECOVERY,
       REPLACE,
       MOVE 'TDE' TO 'E:\TDE.mdf',
      REPLACE,
      MOVE 'TDE_log' TO 'G:\TDE.ldf'
CLOSE MASTER KEY 
GO

--Restore the log backup to the mirrored db
OPEN MASTER KEY DECRYPTION BY PASSWORD = '1Password'
RESTORE LOG TDE
    FROM DISK = '\\SERVERNAME\SQL_Stuff\Backup\TDE_LOG.trn'
    WITH NORECOVERY;
CLOSE MASTER KEY
GO


--Drop/Create Mirroring endpoint on mirror
--DROP ENDPOINT TDE
CREATE ENDPOINT TDE
    STATE = STARTED
    AS TCP ( LISTENER_PORT = 7025 )
    FOR DATABASE_MIRRORING (
        ROLE = PARTNER
        );
GO

--Check the endpoints for the mirror
USE MASTER
SELECT * FROM sys.database_mirroring_endpoints
GO

--Set the principal on the mirrored db
OPEN MASTER KEY DECRYPTION BY PASSWORD = '1Password'
ALTER DATABASE TDE SET PARTNER = 'TCP://PRINCIPAL.DOMAIN.local:7022'
GO
CLOSE MASTER KEY
GO

以下是我在主体服务器上使用的代码。

----------------------Mirroring Section----------------------------------

--Full Backup of Principal
USE TDE
GO
BACKUP DATABASE TDE
TO DISK = '\\SERVERNAME\SQL_Stuff\Backup\TDE_FULL.bak'
    WITH COMPRESSION,
         NAME = 'Full Backup of TDE';
GO

---Log Backup of Principal
USE TDE
GO
BACKUP LOG TDE
TO DISK = '\\SERVERNAME\SQL_Stuff\Backup\TDE_LOG.trn'
    WITH COMPRESSION,
         NAME = 'Log backup of TDE'
GO

--Drop/Create Mirroring endpoint on principal
--DROP ENDPOINT TDE
CREATE ENDPOINT TDE
    STATE = STARTED
    AS TCP ( LISTENER_PORT = 7022 )
    FOR DATABASE_MIRRORING (
        ROLE = PARTNER
        );
GO

--Check the endpoints for the princple
USE master
select * from sys.database_mirroring_endpoints
GO

--Set the mirror db on the principal db
OPEN MASTER KEY DECRYPTION BY PASSWORD = '1Password'
ALTER DATABASE TDE SET PARTNER = 'TCP://MIRROR.DOMAIN.local:7025'
CLOSE MASTER KEY
GO

我设置了镜像端点1st，然后是主体端点。然后，ALTER DATABASE在镜像上，然后在主体上，发出，得到错误：

 Msg 1416, Level 16, State 31, Line 2
Database "TDE" is not configured for database mirroring.

我对此无所适从。镜像处于“正在还原”状态，但是我可以肯定该错误是在谈论主体数据库。

谢谢你提供的所有帮助！

主体TDE的更新代码：

--Create Master Key in Master Database
USE MASTER
GO
CREATE MASTER KEY ENCRYPTION BY PASSWORD = '1Password';
PRINT 'created master key'
go

--Backing up the master key file
USE master;
OPEN MASTER KEY DECRYPTION BY PASSWORD = '1Password';
BACKUP MASTER KEY TO FILE = '\\SERVERNAME\TDE_Master_Key.key' ENCRYPTION BY PASSWORD = '1Password';
GO

--Create Server Certificate in the Master Database encrypted with master key (created above) which would be used to create USER database encryption key.
USE Master
CREATE CERTIFICATE Cert_For_TDE WITH SUBJECT = 'Master_Cert_for_TDE', EXPIRY_DATE = '3500-Jan-01';
Go

--Backing up the server cert file
--USE master;
BACKUP CERTIFICATE Cert_For_TDE TO FILE = '\\SERVERNAME\TDE_Cert.cer' 
    WITH PRIVATE KEY ( FILE = '\\SERVERNAME\TDE_Cert_Key.key', ENCRYPTION BY PASSWORD = '1Password');
GO

--Create user database key
USE TDE
CREATE DATABASE ENCRYPTION KEY
WITH ALGORITHM = AES_256 ENCRYPTION BY SERVER CERTIFICATE Cert_For_TDE;
GO

--Enabling Transparent Database Encryption for the USER Database
USE master;
GO
ALTER DATABASE TDE SET ENCRYPTION ON
GO

TDE的镜像代码：

--restore the backed up key to the mirror
use master
RESTORE MASTER KEY
    FROM FILE = '\\SERVERNAME\TDE_Master_Key.key'
    DECRYPTION BY PASSWORD = '1Password'
    ENCRYPTION BY PASSWORD = '1Password';
GO

--restore the backed up cert to the mirror
USE Master;
OPEN MASTER KEY DECRYPTION BY PASSWORD = '1Password'
CREATE CERTIFICATE Cert_For_TDE    
FROM FILE = '\\SERVERNAME\TDE_Cert.cer' WITH PRIVATE KEY ( FILE = '\\SERVERNAME\TDE_Cert_Key.key', DECRYPTION BY PASSWORD = '1Password');
GO

Principal上的Update2 sys.database_mirroring_endpoints与sys.tcp_endpoints结合在一起：

endpoint_id name    principal_id    state_desc  role_desc   connection_auth_desc    certificate_id  encryption_algorithm_desc   port    ip_address
65545   TDE 261 STARTED PARTNER NEGOTIATE   0   RC4 7022    NULL

在镜像上将sys.database_mirroring_endpoints与sys.tcp_endpoints结合在一起显示：

endpoint_id name    principal_id    state_desc  role_desc   connection_auth_desc    certificate_id  encryption_algorithm_desc   port    ip_address
65537   TDE 261 STARTED PARTNER NEGOTIATE   0   RC4 7025    NULL

找到一个带有评论的网站。

我将代码添加到还原密钥和证书的位置之后

--Mumbojumbo to get mirroring to work
OPEN MASTER KEY DECRYPTION BY PASSWORD = '1Password'
ALTER MASTER KEY ADD ENCRYPTION BY SERVICE MASTER KEY
GO

它的工作原理就像一个护身符，从某种意义上说，我必须使用新服务器的服务主密钥来加密还原的主密钥。我猜。
