使用 CodeDeploy 將 Node JS 應用程序部署到 AWS EC2

Question

我正在嘗試使用 CodeDeploy 將一個非常基本的 Node JS 應用程序部署到 AWS EC2 實例上。 我遇到了部署失敗的問題，因為 Node JS 應用程序已經在運行應用程序的端口上運行。 我不完全確定如何處理這種情況。 該應用程序設計為在端口 3000 上運行。下面是我從 CodeDeploy 正在執行的腳本中得到的錯誤消息。 我嘗試進入實例並終止在端口 3000 上運行的進程，但似乎在終止進程后應用程序立即重新啟動。 請讓我知道是否需要任何幫助。 任何意見，將不勝感激。

您可以在項目中更改端口號，或者您可以在 EC2 實例上終止 3000 端口:)。
