SQL Server 數(shù)據(jù)庫添加AlwaysOn高可用自定義登陸用戶的方法
2021-12-01 23:09:17

--花了點時間搜羅了網(wǎng)上的相關文章,然后作了簡單匯總,以方便查閱

--1、在主庫上建立用戶并查詢出SID,用于輔庫上創(chuàng)建同步用戶

use tsdb GO select [sid] from sys.syslogins where name='user' GO use master select [sid] from sys.syslogins where name='user'


SELECT * FROM [dbName]..sysusers

--2、在輔庫上創(chuàng)建同步用戶,使用主庫用戶的SID,以繼承訪問許可 CREATE LOGIN [user] WITH PASSWORD = 'password', SID = 0x00000000000000000000000000000000, --從上面的查詢從獲取 DEFAULT_DATABASE = [tsdb], --默認數(shù)據(jù)庫 CHECK_EXPIRATION = OFF, --強制密碼過期 關閉 CHECK_POLICY = OFF --強制密碼策略 關閉

--網(wǎng)上傳的兩位大神的腳本和導出語句,原本不改羅列如下, --方法一 --先在主庫創(chuàng)建好用戶,并用以下腳本創(chuàng)建2個存儲過程(sp_help_revlogin和sp_hexadecimal) --然后執(zhí)行sp_help_revlogin存儲過程,在結果里找到所需創(chuàng)建用戶的語句并復制該語句到副庫執(zhí)行以創(chuàng)建同步用戶

1.在主服務器添加自定義登陸用戶,比如TestUser

2.在主服務器執(zhí)行如下SQL,在master數(shù)據(jù)庫創(chuàng)建存儲過程sp_hexadecimal,sp_help_revlogin

創(chuàng)建sp_help_revlogin存儲過程

3.執(zhí)行sp_help_revlogin存儲過程,在得到的結果文本里,找到TestUser相關的那條創(chuàng)建用戶的腳本。

4.復制該腳本至其他副本數(shù)據(jù)庫執(zhí)行
