最近在搞在SQL 2005安装数据库镜像，中间遇到不少的错误，在此归纳总结，以方便有需要的朋友参考。

     直接上脚本，主机部分：

---修改数据库为完整恢复模式
USE master;
ALTER DATABASE CZTest
SET RECOVERY FULL;
--------创建证书
USE master;
CREATE MASTER KEY ENCRYPTION BY PASSWORD = ‘23987hxJ#KL95234nl0zBe‘;--创建数据库密钥，并提供密钥使用密码
CREATE CERTIFICATE HOST_A_cert WITH SUBJECT = ‘HOST_A certificate‘ ,
START_DATE = ‘07/08/2014‘;
--------创建连接端口
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 AES , ROLE = ALL );

----------备份证书
BACKUP CERTIFICATE HOST_A_cert TO FILE = ‘D:\SQLBackup\HOST_A_cert.cer‘;
----------互换证书
--操作完毕
----------添加登陆名和用户
CREATE LOGIN Login_B WITH PASSWORD = ‘2014sa‘;
CREATE USER User_B FOR LOGIN Login_B;
CREATE CERTIFICATE HOST_B_cert AUTHORIZATION User_B FROM FILE = ‘D:\SQLBackup\HOST_B_cert.cer‘;
GRANT CONNECT ON ENDPOINT::Endpoint_Mirroring TO Login_B;--准许HOST_B_login登陆名连接到端口

-----------手工同步登录名和密码
----login B的sid=0x5AA61C2F8FFA0B45AC27EEB148083CD9
select sid,name from syslogins;

----创建镜像（未成功 原因：1.数据库完整备份，事务日志也要完整备份
----                       2.创建镜像的SQL要首先在备份库中执行，然后在主库执行。顺序不可颠倒）
----                       3.在端点配置中禁用了数据库镜像传输功能：解决办法：DBCC TRACEON(1400,-1)或者安装SP1

----                       4.在安装SP1时遇到了身份验证不能通过，错误显示两个实例，其中还有一个是reporting services，打开reporting services配置，选中数据库连接，配置一下自己的  账户，
ALTER DATABASE ceshi SET PARTNER = ‘TCP://192.168.137.13:5022‘;
ALTER DATABASE HxCreditBuy SET PARTNER = ‘TCP://192.168.137.13:5022‘;
-----下面这句执行成功
ALTER DATABASE CZTest SET PARTNER = ‘TCP://192.168.137.13:5022‘;
-------------==========检查脚本======================

DROP LOGIN HOST_B_login
DROP USER HOST_B_user

DBCC TRACEON(1400,-1)

DROP MASTER KEY
DROP CERTIFICATE HOST_A_cert

--检查主机和备机的证书是否存在：
select name, start_date, expiry_date from sys.certificates where name not like ‘##%‘

--删除镜像数据库证书
--drop the old cert for the principal login
use master
DROP CERTIFICATE HOST_A_cert
GO
use master
DROP CERTIFICATE HOST_B_cert
GO


--检查镜像端口
SELECT * FROM sys.endpoints  where type=4

--删除端口
use master
DROP Endpoint Endpoint_Mirroring
GO
