将 CakePHP 应用程序部署到 AWS ElasticBeanstalk EC2 实例

Question

我正在尝试设置我的第一个 AWS EC2 实例来部署我现有的 CakePHP 应用程序。该应用程序在本地运行完美，但我似乎无法让 EC2 实例上的应用程序连接到数据源。在尝试加载应用程序时，我在页面顶部收到以下一组错误：

Warning (2): mysql_connect(): php_network_getaddresses: getaddrinfo failed: Name or service not known [CORE/cake/libs/model/datasources/dbo/dbo_mysql.php, line 561]
Warning (2): mysql_query() expects parameter 2 to be resource, boolean given [CORE/cake/libs/model/datasources/dbo/dbo_mysql.php, line 613]

我一直在关注有关如何将 Cake 应用程序部署到实例的 AWS 教程，但一切似乎都是正确的： http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/create_deploy_PHP_cakePHP.html

我的数据库配置文件在这里。它的设置方式与教程相同：

if (!defined('RDS_HOSTNAME')) {
  define('RDS_HOSTNAME', $_SERVER['RDS_HOSTNAME']);
  define('RDS_USERNAME', $_SERVER['RDS_USERNAME']);
  define('RDS_PASSWORD', $_SERVER['RDS_PASSWORD']);
  define('RDS_DB_NAME', $_SERVER['RDS_DB_NAME']);
}
class DATABASE_CONFIG {
        //live server (Amazon ECS)
        var $default = array(
                'driver' => 'mysql',
                'persistent' => false,
                'host' => 'RDS_HOSTNAME',
                'login' => 'RDS_USERNAME',
                'password' => 'RDS_PASSWORD',
                'database' => 'RDS_DB_NAME',
                'prefix' => '',
        );
}

提前感谢大家！

您在数据库配置中使用字符串，而不是您定义的常量。
