我在AWS上运行了一个Web应用程序，以及一个MySQL数据库实例。我已经设置了我的本地环境来运行symfony应用程序并连接到aws db实例就好了。在尝试部署时，一切都很好，直到我添加了MySQL的东西。现在，当我部署时，composer install hook失败了，我还剩下这个输出：
categories有趣的是，我上传的这个特定的zip文件中甚至没有作曲家。*文件。所以我对它的看法有点困惑。我认为我的问题是没有为我的数据库连接设置正确的值。但是，我使用命名方案SYMFONY__ENV__MYSQL__SERVER等将环境变量添加到我的环境配置中......
这是我的parameters.yml.dist文件：

Running composer as root/super user is highly discouraged as packages, plugins and scripts cannot always be trusted

问题是我的Web应用程序实例没有（通过安全组）访问我的数据库实例。我是如何修理的，非常基础。我删除了当前的数据库实例，并从Web应用程序控制台创建了一个新实例 - ＆gt;配置 - ＆gt;数据层。然后，我重建了环境，现在似乎正在运作。
