Question

我正在查看将数据库添加到 elastic beanstalk python 文档，但按照步骤操作会导致以下错误

我做了一些挖掘，得出的结论是 mysql 或 mariadb 没有安装到 ec2 实例中。因此，我开始浏览Amazon Linux 2023 AMI 的可用软件包.ebextensions，因为我的 ec2 正在运行该版本，并将文件夹中的配置修改为如下所示：

软件包安装成功，但我仍然收到同样的错误。当我通过 ssh 进入 ec2 设备手动安装 mysql 或 mariadb 时，终端告诉我：

如果实例被自动扩展替换，通过 SSH 所做的更改\n将丢失

所以我的问题是：\n在使用 Elastic beanstalk 部署应用程序时，如何将 mysql 或 mariadb 安装到 ec2 实例上，这样我就可以mysqlclient==2.0.3在我的requirements.txt

\n

我的requirements.txt

\n

asgiref==3.6.0\nbranca==0.6.0\ncertifi==2022.12.7\ncharset-normalizer==3.1.0\nDjango==4.2.1\nfolium==0.14.0\nidna==3.4\nJinja2==3.1.2\nMarkupSafe==2.1.2\nnumpy==1.24.3\npython-dotenv==1.0.0\nrequests==2.29.0\nsqlparse==0.4.4\ntzdata==2023.3\nurllib3==1.26.15\nmysqlclient==2.0.3\n

\n

编辑：收到安装名称以 -dev 或 -devel 结尾的 mariadb 软件包的反馈，但Amazon Linux 2023 AMI 的可用软件包列表中没有列出此类软件包，任何进一步的指示将不胜感激！

经过一番尝试和错误后，我最终修改了我的配置文件以从此开始，这解决了我的问题

packages:
  yum:
    mariadb105-devel: []

我完全是偶然发现了这个包裹。如果有人知道如何在未来发现这些，请告诉我
