如何解決在連線至 Microsoft SQL Server 資料庫的 Elastic Beanstalk PHP 平台上部署應用程式時,我所收到的 PHP 嚴重錯誤?
在連線至 Microsoft SQL Server 資料庫的 AWS Elastic Beanstalk PHP 平台上部署應用程式時,我收到一個 PHP 嚴重錯誤。
簡短說明
在連線至 Microsoft SQL Server 資料庫的 Elastic Beanstalk PHP 平台上部署應用程式時,您可能會收到下列錯誤: "PHP Fatal error: Uncaught Error: Call to undefined function sqlsrv_connect() in /var/app/current/DB/ (PHP 嚴重錯誤:無法識別的錯誤:在 /var/app/current/DB/ 呼叫未定義的函數 sqlsrv_connect())"
若要將 PHP 連線至 Microsoft SQL Server 資料庫,您必須先安裝並設定 SQLSRV 程式庫及其 PDO 延伸功能。依預設,系統不會安裝及設定此程式庫和延伸功能。
若要安裝 SQLSRV 程式庫和 PDO 延伸功能,您可以使用 .ebextensions 組態檔在 Amazon Elastic Compute Cloud (Amazon EC2) 執行個體中執行指令碼。該指令碼會執行下列動作:
- 安裝適用於 Microsoft SQL Server 的正確驅動程式和工具
- 啟用所需的 PHP 程式庫和延伸功能
解決方法
**注意:**下列步驟適用於任何 PHP 平台版本的 Elastic Beanstalk 環境。
1. 在應用程式套件組合的根目錄中,建立名為 .ebextensions 的目錄。
2. 建立一個 .ebextensions 組態檔,例如下列 .ebextensions/pdo_sqlsrv.config. 檔案:
重要事項: 以下解決方法所用的 .ebextensions 檔案僅適用於 Amazon Linux 1 和 Amazon Linux 2 Amazon Machine Image (AMI) 執行個體。**.ebextensions ** 檔案不適用於 Windows 或 Elastic Beanstalk 中的自訂 Ubuntu AMI 執行個體。

3. 建立一個應用程式來源套件組合,其中包含您從步驟 2 建立的 .ebextensions 檔案。
