在 SQL Server 中設(shè)置主從數(shù)據(jù)庫權(quán)限涉及幾個關(guān)鍵步驟,以確保數(shù)據(jù)的安全性和完整性。以下是一個基本的指南:
創(chuàng)建用戶和角色:
ReplicationReader
),并授予該角色對主數(shù)據(jù)庫的讀取權(quán)限。-- 創(chuàng)建用戶
CREATE USER [ReplicationUser] FROM EXTERNAL PROVIDER;
-- 授予角色
ALTER ROLE [ReplicationReader] ADD MEMBER [ReplicationUser];
-- 授予角色對主數(shù)據(jù)庫的讀取權(quán)限
GRANT SELECT ON ALL TABLES IN SCHEMA public TO [ReplicationReader];
配置復(fù)制:
-- 啟用復(fù)制
ALTER DATABASE [YourDatabaseName] SET REPLICATION;
-- 創(chuàng)建發(fā)布
EXEC sp_addpublication @publication = 'YourPublicationName', @description = 'YourDescription';
-- 配置發(fā)布選項
EXEC sp_publish @publication = 'YourPublicationName', @article = 'YourArticleName', @type = 'none';
創(chuàng)建用戶和角色:
ReplicationSubscriber
),并授予該角色對從數(shù)據(jù)庫的寫入權(quán)限。-- 創(chuàng)建用戶
CREATE USER [ReplicationUser] FROM EXTERNAL PROVIDER;
-- 授予角色
ALTER ROLE [ReplicationSubscriber] ADD MEMBER [ReplicationUser];
-- 授予角色對從數(shù)據(jù)庫的寫入權(quán)限
GRANT INSERT, UPDATE, DELETE ON ALL TABLES IN SCHEMA public TO [ReplicationSubscriber];
配置訂閱:
-- 創(chuàng)建訂閱
EXEC sp_addsubscription @publication = 'YourPublicationName', @subscriber = 'YourSubscriberServer', @subscriber_db = 'YourSubscriberDatabase', @connection_string = 'YourConnectionString';
檢查權(quán)限:
ReplicationUser
只有讀取權(quán)限。ReplicationSubscriber
只有寫入權(quán)限。審計和日志:
以下是一個完整的示例腳本,展示了如何在主從數(shù)據(jù)庫中設(shè)置權(quán)限:
-- 主數(shù)據(jù)庫配置
USE [YourDatabaseName];
-- 創(chuàng)建用戶
CREATE USER [ReplicationUser] FROM EXTERNAL PROVIDER;
-- 授予角色
ALTER ROLE [ReplicationReader] ADD MEMBER [ReplicationUser];
-- 授予角色對主數(shù)據(jù)庫的讀取權(quán)限
GRANT SELECT ON ALL TABLES IN SCHEMA public TO [ReplicationReader];
-- 啟用復(fù)制
ALTER DATABASE [YourDatabaseName] SET REPLICATION;
-- 創(chuàng)建發(fā)布
EXEC sp_addpublication @publication = 'YourPublicationName', @description = 'YourDescription';
-- 配置發(fā)布選項
EXEC sp_publish @publication = 'YourPublicationName', @article = 'YourArticleName', @type = 'none';
-- 從數(shù)據(jù)庫配置
USE [YourSubscriberDatabase];
-- 創(chuàng)建用戶
CREATE USER [ReplicationUser] FROM EXTERNAL PROVIDER;
-- 授予角色
ALTER ROLE [ReplicationSubscriber] ADD MEMBER [ReplicationUser];
-- 授予角色對從數(shù)據(jù)庫的寫入權(quán)限
GRANT INSERT, UPDATE, DELETE ON ALL TABLES IN SCHEMA public TO [ReplicationSubscriber];
-- 創(chuàng)建訂閱
EXEC sp_addsubscription @publication = 'YourPublicationName', @subscriber = 'YourSubscriberServer', @subscriber_db = 'YourSubscriberDatabase', @connection_string = 'YourConnectionString';
通過以上步驟,您可以在 SQL Server 中設(shè)置主從數(shù)據(jù)庫的權(quán)限,確保數(shù)據(jù)的安全性和完整性。
