1、還原Master數(shù)據(jù)庫
如果系統(tǒng)配置丟失或Master出現(xiàn)問題,可以進入單用戶模式進行還原;如果出現(xiàn)下列情況,必須重新生成損壞的 master 數(shù)據(jù)庫:
A. master 數(shù)據(jù)庫的當(dāng)前備份不可用。
B. 存在 master 數(shù)據(jù)庫備份,但由于 Microsoft SQL Server 實例無法啟動,因此無法還原該備份。
1、重新生成 master 數(shù)據(jù)庫:
注意:
在 SQL Server 2005 中已廢止 Rebuildm.exe 程序。若要重新生成 master 數(shù)據(jù)庫,請使用 setup.exe。
1、 Start /wait setup.exe /qn INSTANCENAME=<InstanceName> REINSTALL=SQL_Engine REBUILDDATABASE=1 SAPWD=<NewStrongPassword>
例:start /wait e:“setup.exe /qn INSTANCENAME=mssqlserver REINSTALL=SQL_Engine REBUILDDATABASE=1 SAPWD=abc123@!@
注:INSTANCENAME:指定實例名,默認實例則用mssqlserver表示
REINSTALL:指定引擎
SAPWD:強密碼
Setup.exe:指定光盤1中的根目錄下的文件
/qn 開關(guān)用于取消所有安裝程序?qū)υ捒蚝湾e誤消息。如果指定 /qn 開關(guān),則所有安裝程序消息(包括錯誤消息)都將寫入安裝程序日志文件。有關(guān)日志文件的詳細信息,請參閱如何查看 SQL Server 2005 安裝日志文件。
指定 /qb 開關(guān)將顯示基本的安裝程序?qū)υ捒?。還會顯示錯誤消息。
2、 還原Master備份(在恢復(fù)master的備份時要注意:必須在單用戶(single user)模式下進行 ) a.進入單用戶模式的方法:
1.在命令行模式下輸入sqlservr -c -f -m或者輸入sqlservr -m
其中:-c 可以縮短啟動時間,SQL Server 不作為Windows NT的服務(wù)啟動
-f 用最小配置啟動SQL Server
-m 單用戶模式啟動SQL Server
2.系統(tǒng)默認沒有設(shè)置PATH,先進入CMD,進入“C:“Program Files“Microsoft SQL Server“MSSQL.1“MSSQL“Binn”,執(zhí)行SQLSERVR.EXE –M
打開SSMS工具,先斷開連接,再新建查詢,執(zhí)行以下命名還原
USE master
GO
RESTORE DATABASE master
FROM disk=‘c:“master.bak‘
GO
開始實驗了~~~ MASTER重新生成
為了模擬MASTER數(shù)據(jù)庫壞了,我們就刪除MASTER數(shù)據(jù)庫(要停止SQL SERVER服務(wù)才能刪除)在我的電腦,C:“ PROGRAM FILES“MICROSOFT SQL SERVER“MSSQL.1“MSSQL“DATE 中刪除MASTER.MDF
重新生成MASTER
1.首先在CMD中輸入
start /wait setup.exe /qn INSTANCENAME=<InstanceName> REINSTALL=SQL_Engine REBUILDDATABASE=1 SAPWD=<NewStrongPassword>
其中的 SETUP.EXE為啟動光盤的路徑,我這里的是 E:“SETUP.EXE /QN
我這里的為默認實例所以其中的<INSTANCENAME>用 MSSQLSERVER代替
最后的<NewStrongPassword>為密碼我設(shè)密碼為abc123@!@,所以就用abc123@!@代替<NewStrongPassword>
若沒有返回錯誤,我們就可以到我的電腦中C:“ PROGRAM FILES“MICROSOFT SQL SERVER“MSSQL.1“DATE上面又有MASTER.MDF了
接下來進入目錄
單用戶模式
啟動SSMS工具,新建查詢
輸入命令
啟動服務(wù)(MSSQL SERVER)
打開SSMS
連接到數(shù)據(jù)庫后就可以發(fā)現(xiàn)數(shù)據(jù)庫中的數(shù)據(jù)又回來了
以下是我在命令行下搞的命令,我用記事本的方式全部復(fù)制下來了,為了不傳附件,我就直接粘貼到下面了
