在 Docker 容器中還原 SQL Server 資料庫(.bak檔案)
阿新 • • 發佈：2020-12-13
系統環境:
macOS BigSur 版本11.0.1
本文預設系統已經在docker中拉取完成sqlserver映象.
- 首先在Docker Dashboard中執行sqlserver映象
要檢視 Docker 容器，請使用 docker ps 命令
sudo docker ps -a
如果“狀態”列顯示“正常執行”，則 SQL Server 將在容器中執行，並偵聽“埠”列中指定的埠 。
- 將備份檔案複製到容器中
①首先，使用 docker exec 來建立備份資料夾。 以下命令在 SQL Server 容器中建立 /var/opt/mssql/backup 目錄 。
sudo docker exec -it sqlserver mkdir /var/opt/mssql/backup
②使用 docker cp 將備份檔案複製到 /var/opt/mssql/backup 目錄的容器中 。
sudo docker cp 檔名.bak sqlserver:/var/opt/mssql/backup
- 還原資料庫
備份檔案現在位於容器內。 在還原備份之前，請務必瞭解備份中的邏輯檔名和檔案型別。 以下 Transact-SQL 命令使用容器中的 sqlcmd 檢查備份並執行還原 。
①在容器中執行 sqlcmd，列出備份中的邏輯檔名和路徑 。 這是通過“RESTORE FILELISTONLY”Transact-SQL 語句實現的 。
sudo docker exec -it sqlserver /opt/mssql-tools/bin/sqlcmd -S localhost \
-U SA -P '<YourNewStrong!Passw0rd>' \
-Q 'RESTORE FILELISTONLY FROM DISK = "/var/opt/mssql/backup/檔名.bak"' \
| tr -s ' ' | cut -d ' ' -f 1-2
YourNewStrong!Passw0rd 部分要替換成安裝資料庫時設定好的密碼
.bak檔案的 檔名 部分要替換成實際的檔名
會得到 類似於
LogicalName PhysicalName
------------------------------------------
WWI_Primary D:\Data\WideWorldImporters.mdf
WWI_UserData D:\Data\WideWorldImporters_UserData.ndf
WWI_Log E:\Log\WideWorldImporters.ldf
WWI_InMemory_Data_1 D:\Data\WideWorldImporters_InMemory_Data_1
②呼叫 RESTORE DATABASE 命令，還原容器中的資料庫 。 為上一步中的每個檔案指定新路徑。
這裡以 WideWorldImporters 資料庫為例，實際使用時要將程式碼中的資料庫名、檔名、目錄按需求更改。
sudo docker exec -it sql1 /opt/mssql-tools/bin/sqlcmd \
-S localhost -U SA -P '<YourNewStrong!Passw0rd>' \
-Q 'RESTORE DATABASE WideWorldImporters FROM DISK = "/var/opt/mssql/backup/wwi.bak" WITH MOVE "WWI_Primary" TO "/var/opt/mssql/data/WideWorldImporters.mdf", MOVE "WWI_UserData" TO "/var/opt/mssql/data/WideWorldImporters_userdata.ndf", MOVE "WWI_Log" TO "/var/opt/mssql/data/WideWorldImporters.ldf", MOVE "WWI_InMemory_Data_1" TO "/var/opt/mssql/data/WideWorldImporters_InMemory_Data_1"'
會得到類似於下面的輸出:
Processed 1464 pages for database 'WideWorldImporters', file 'WWI_Primary' on file 1.
Processed 53096 pages for database 'WideWorldImporters', file 'WWI_UserData' on file 1.
Processed 33 pages for database 'WideWorldImporters', file 'WWI_Log' on file 1.
Processed 3862 pages for database 'WideWorldImporters', file 'WWI_InMemory_Data_1' on file 1.

RESTORE DATABASE successfully processed 58455 pages in 18.069 seconds (25.273 MB/sec).
③驗證還原的資料庫
執行以下查詢以在容器中顯示資料庫名稱的列表：
sudo docker exec -it sqlserver /opt/mssql-tools/bin/sqlcmd \
-S localhost -U SA -P '<YourNewStrong!Passw0rd>' \
-Q 'SELECT Name FROM sys.Databases'
資料庫列表中應會顯示 WideWorldImporters 。
此時在Datagrip中重新整理資料庫，還原出的資料庫就成功顯示出來了！
