Database Mirroring dengan TDE

Saya memiliki persyaratan mirroring beberapa database dan juga menggunakan enkripsi data transparan (TDE) pada mereka karena data kami harus dienkripsi sambil 'saat istirahat'.

Saya memiliki pengaturan TDE pada kepala sekolah dan cermin. Masalah yang saya hadapi saat saya mengatur mirroring dari dua database. Karena saya menggunakan TDE, saya tidak tahu cara mengatur mirroring melalui gui, jadi saya terpaksa menggunakan t-sql untuk menyelesaikan pekerjaan.

Di bawah ini adalah kode yang saya gunakan di server cermin

--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

Di bawah ini adalah kode yang saya gunakan di server utama.

----------------------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

Saya mengatur titik akhir mirroring 1, kemudian titik akhir utama. Saya kemudian mengeluarkan ALTER DATABASEdi cermin, lalu di kepala sekolah, di mana saya mendapatkan kesalahan yang dihasilkan:

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

Saya bingung harus berbuat apa tentang ini. Cermin dalam keadaan "memulihkan", tetapi saya yakin bahwa kesalahannya berbicara tentang db utama.

Terima kasih atas bantuan yang bisa Anda berikan!

Perbarui Kode untuk Kepala Sekolah TDE:

--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

Kode cermin untuk TDE:

--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

Update2 sys.database_mirroring_endpoints bergabung dengan sys.tcp_endpoints pada acara Utama:

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

sys.database_mirroring_endpoints bergabung dengan sys.tcp_endpoints di Mirror show:

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

Menemukan situs web dengan komentar di atasnya.

Saya menambahkan kode tepat setelah saya mengembalikan kunci dan cert

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

Ini bekerja seperti pesona, masuk akal bahwa saya harus mengenkripsi kunci master yang saya pulihkan dengan kunci layanan master dari server baru. Saya kira.
