我在本地机器上使用 Acquia Dev Desktop 构建了一个 Drupal 8 站点。我在 AWS EC2 上安装 Drupal，遇到以下错误。
Failed to connect to your database server. The server reports the
following message: SQLSTATE[HY000] [2002] Connection refused.
我用我的 config.inc 文件检查了数据库名称、用户名、密码和端口，但仍然无法连接。这是带有错误的drupal安装页面的屏幕截图：
这是我的 config.inc 文件信息（使用虚拟密码，但真实版本与我在 Drupal 安装页面中输入的内容匹配）
