問題

我正在嘗試使用小型數據庫后端在 Elastic Beanstalk 上部署一個非常簡單的應用程序.我嘗試安裝 mysqlclient 作為 AWS 此處.但是，當我部署我的應用程序時，我在嘗試下載包時從我的 Elastic Beanstalk 日志中收到以下錯誤:

I am trying to deploy a very simple app on Elastic Beanstalk with a small database backend. I try to install mysqlclient as part of the process outlined by AWS here. However, when I deploy my app, I get the following error from my Elastic Beanstalk logs as it tries to download the package:

Collecting mysqlclient

問題

mysqlclient 是 AWS 推薦的驅動程序，用于使用 Flask 或 Django 連接到 RDS 中的 MySQL 數據庫.如何使用 Elastic Beanstalk 安裝它?

The mysqlclient is the AWS recommended driver to connect to a MySQL database in RDS using Flask or Django. How do I get it installed with Elastic Beanstalk?

背景

我嘗試使用 (1) Elastic Beanstalk 環境內的數據庫或 (2) Elastic Beanstalk 環境外定期部署的 RDS 實例來實現我的架構環境.在這種情況下，我們將使用選項 (1).

I've tried to implement my architecture with either (1) a database within the Elastic Beanstalk environment or (2) a regularly deployed RDS instance outside the Elastic Beanstalk environment. In this case, we're going with option (1).

我無法使用 apt-get 安裝 mysql-server 或其他軟件包作為 在這里建議 很容易，這就是為什么我希望這不會被標記為重復.我無權訪問底層服務器.我嘗試使用平臺掛鉤和 .ebextensions，但我 無法讓它工作.在這篇文章中，我試圖退后一步，看看是否還有其他途徑.

I can't install mysql-server or other packages using apt-get as suggested here very easily, which is why I hope this isn't labeled as a duplicate. I don't have access to the underlying servers. I attempted to using platform hooks and .ebextensions, but I wasn't able to get that to work. In this post, I'm trying to step back and see if there is another avenue.

推薦答案

對于 Amazon linux 2，您應該能夠使用 yum 安裝它.因此，您可以在 .ebextensions 中有一個名為的文件，例如01_packages.config 內容:

For Amazon linux 2 you should be able to install it with yum. Thus, you can have in your .ebextensions a file called, e.g. 01_packages.config with the content:

packages: 
    yum:
        MySQL-python: []

如果您需要更多 yum 依賴項，您可以添加更多.

You can add further yum dependencies if you require more.
