前提：

准备一台电脑，主机名和以前的分发数据库一致。并且安装sql server

恢复步骤：

在新的distribution服务器上

1.配置distribution，增加之前的publisher

2.使用备份还原distribution数据库

3.创建job，主要是快照agent和logreadagent，可以从老的distribution直接复制

3.修改发布服务器属性

  EXEC sp_changedistpublisher  'TESTSYNCDBSERV', 'active', 'true'

4.修改[MSpublisher_databases]中的publisher_id为publisher服务器在sys.servers中的server_id

UPDATE t  set t. publisher_id  = 2  from dbo.[MSpublisher_databases]  t WHERE id=2

5.修改[MSpublications]中的publisher_id为publisher服务器在sys.servers中的server_id

UPDATE t set t. publisher_id  = 2 from dbo.MSpublications  t WHERE publication_id=2

6.修改[MSdistribution_agents]中的publisher_id为publisher服务器在sys.servers中的server_id,subscriber_id为订阅服务器在sys.servers中的server_id，如果没有订阅的可以直接创建。

 EXEC master.dbo.sp_addlinkedserver @server = N'TESTSYNCRPTSERV', @srvproduct=N'SQL Server'
 EXEC master.dbo.sp_addlinkedsrvlogin @rmtsrvname=N'TESTSYNCRPTSERV',@useself=N'True',@locallogin=NULL,@rmtuser=NULL,@rmtpassword=NULL
 update dbo.MSdistribution_agents SET publisher_id=2,subscriber_id=3 WHERE id = 4

7.修改[MSsubscriptions]中的publisher_id为publisher服务器在sys.servers中的server_id,subscriber_id为订阅服务器在sys.servers中的server_id，如果没有订阅的可以直接创建。

update dbo.MSsubscriptions  SET publisher_id =2,subscriber_id=3 WHERE publication_id=2

8.修改logreadagent，snapshotagent的publish_id和对应的job信息

 update [MSlogreader_agents]  SET publisher_id =2  WHERE id = 2
 update [MSsnapshot_agents]  SET publisher_id =2  WHERE id = 2
 update t
  set t.job_id = sj.job_id, t.job_step_uid = sjs.step_uid
 from dbo.MSlogreader_agents t
  left join dbo.MSreplication_monitordata   sm on sm.agent_name = t.name
  left join msdb.dbo.sysjobs sj  on sj.name = t.name
  left join msdb.dbo.sysjobsteps sjs on sj.job_id = sjs.job_id and sjs.step_id = 2
 update t
  set t.job_id = sj.job_id, t.job_step_uid = sjs.step_uid
 from dbo.[MSsnapshot_agents] t
  left join dbo.MSreplication_monitordata   sm on sm.agent_name = t.name
  left join msdb.dbo.sysjobs sj  on sj.name = t.name
  left join msdb.dbo.sysjobsteps sjs on sj.job_id = sjs.job_id and sjs.step_id = 2

在发布上运行

修改发布数据库中的syspublications，syssubscriptions中job的id

update [dbo].[syspublications] set snapshot_jobid=0xD2E257AFD287304CA2FC14F3D7C1AECF
update [dbo].[syssubscriptions] set distribution_jobid=0x0E79D3A2A36F73409DB3F4261723F37A
