將CakePHP應用程序部署到AWS ElasticBeanstalk EC2實例

Question

我正在嘗試設置我的第一個AWS EC2實例，以部署我的現有CakePHP應用程序。 該應用程序可以在本地完美運行，但是我似乎無法讓EC2實例上的應用程序連接到數據源。 嘗試加載應用程序后，我在頁面頂部收到以下錯誤集：

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]

Warning (2): mysql_real_escape_string() expects parameter 2 to be resource, boolean given [CORE/cake/libs/model/datasources/dbo/dbo_mysql.php, line 684]

應用程序實時URL： http : //orderaslice-demo.elasticbeanstalk.com/

我一直在遵循有關如何將Cake應用程序部署到實例的AWS教程，但是一切似乎都是正確的： http : //docs.aws.amazon.com/elasticbeanstalk/latest/dg/create_deploy_PHP_cakePHP.html

我的數據庫配置文件在這里。 它的設置方法與教程相同：

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' => '',
        );
}

在此先感謝大家！

您在數據庫配置中使用的是字符串，而不是定義的常量。
