镜像服务器(***.88.55.224)
主体服务器(***.88.55.223)
?
1.迁移数据库备份(***.88.55.168)
use master
?
GO
?
backup DATABASE db_mydb To Disk = ‘D:\portalBak\portal0902.bak‘ WITH FORMAT; --2s
?
go
?
2.把备份拷贝到要恢复的机器中
?
3.服务器数据库恢复
?
use master
?
go
?
RESTORE DATABASE db_mydb
FROM DISK =‘d:\portalBak\portal0902.bak‘ WITH NORECOVERY,
MOVE ‘db_mydb‘ TO ‘D:\portalData
\db_mydb.MDF‘,
MOVE ‘db_mydb_log‘ TO ‘D:\portalData\db_mydb_log.LDF‘
?
GO
?
use master
?
go
?
RESTORE DATABASE db_mydb
FROM DISK =‘d:\portalBak\portal0902.bak‘ WITH RECOVERY,
MOVE ‘db_mydb‘ TO ‘D:\portalData
\db_mydb.MDF‘,
MOVE ‘db_mydb_log‘ TO ‘D:\portalData\db_mydb_log.LDF‘
?
GO
?
4.建立数据库端点(只需要创建一次)
CREATE ENDPOINT [Endpoint_db_mydb]
AUTHORIZATION [IT-PORTAL-1-224\meizuadmin]
STATE=STARTED
AS TCP (LISTENER_PORT =
5022, LISTENER_IP = ALL)
FOR DATA_MIRRORING (ROLE = ALL, AUTHENTICATION = WINDOWS NEGOTIATE
, ENCRYPTION = REQUIRED)
?
CREATE ENDPOINT [Endpoint_db_mydb]
AUTHORIZATION [IT-PORTAL-1-223\meizuadmin]
STATE=STARTED
AS TCP (LISTENER_PORT =
5022, LISTENER_IP = ALL)
FOR DATA_MIRRORING (ROLE = ALL, AUTHENTICATION = WINDOWS NEGOTIATE
, ENCRYPTION = REQUIRED)
?
5.配置镜像命令 (ip为主体ip)
镜像:
use master
?
go
?
ALTER DATABASE db_mydb SET PARTNER =N‘TCP://***.88.55.223:5022‘;
?
go
?
主体:
use master
?
go
?
ALTER DATABASE db_mydb SET PARTNER =N‘TCP://***.88.55.224:5022‘;
?
go
?
6.事务安全模式(同步/异步)
主体
ALTER DATABASE db_mydb SET PARTNER SAFETY FULL;
?
7.同步两服务器的登录用户
主体:
use master;
select sid,name from syslogins where name = ‘portalweb_aspnet‘;
?
镜像:
USE master;
?
exec sp_addlogin
@loginame = ‘portalweb_aspnet‘,
@passwd = ‘2B6kwY7T7Pn7ZuCl‘,
@sid
=0x0330DEF76AE2484CA75FD1DC660EDFB1;
?
?
测试:
1.主备互换
主体:
USE master
?
go
?
ALTER DATABASE db_mydb SET PARTNER FAILOVER;
?
go
?
镜像:
USE master
?
go
?
ALTER DATABASE db_mydb SET PARTNER FORCE_SERVICE_ALLOW_DATA_LOSS;
?
go
?
2.原来的主服务器恢复,可以继续工作,需要重新设置镜像
镜像:
USE master;
?
go
?
ALTER DATABASE db_mydb SET PARTNER RESUME; --恢复镜像
ALTER DATABASE db_mydb SET PARTNER FAILOVER; --切换主备
?
go
?
?
3.原来的主服务器恢复,可以继续工作
USE master;
?
go
?
ALTER DATABASE db_mydb SET PARTNER SAFETY FULL; --事务安全,同步模式
?
go
?
<add name="DefaultConnection" providerName="System.Data.SqlClient" connectionString="Data Source=1...238;Failover Partner=1...239;Initial Catalog=as_mydb;Persist Security Info=True;User ID=aaa;Password=aaa" />
