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，以部署我的现有CakePHP应用程序。 该应用程序可以在本地完美运行，但是我似乎无法让EC2实例上的应用程序连接到数据源。 尝试加载应用程序后，我在页面顶部收到以下错误集：

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]

我一直在遵循有关如何将Cake应用程序部署到实例的AWS教程，但是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。 它的设置方法与教程相同：

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' => '',
        );
}

在此先感谢大家！

您在数据库配置中使用的是字符串，而不是定义的常量。
