mysql - 具有 Doctrine 的symfony2无法连接到远程mysql数据库

Question

我正在部署我的 symfony2 项目，但我遇到了与远程 mysql 服务器的数据库连接问题。似乎 symfony 仍在尝试连接到本地 mysql 实例(使用套接字而不是 tcp)并且没有考虑正确设置的 parameteres.yml。

参数.yml

parameters:
  database_driver:   pdo_mysql
  database_host:     subdomain-example.dotcloud.net
  database_port:     44569
  database_name:     db_platform
  database_user:     root
  database_password: [intentionally hidden]

config.yml

imports:
  - { resource: parameters.yml }

doctrine:
  dbal:
    default_connection:       default
    connections:
        default:
            driver:           %database_driver%
            dbname:           %database_name%
            user:             %database_user%
            password:         %database_password%
            host:             %database_host%
            port:             %database_port%
            charset:          UTF8

错误堆栈跟踪(当我尝试清除缓存时由控制台显示或由 http 浏览器显示)

PDOException: SQLSTATE[28000] [1045] Access denied for user 'root'@'localhost' (using password: YES)
in /var/www/Symfony/app/cache/dev/appDevDebugProjectContainer.php line 2336

正如您在上面看到的，配置文件中没有“localhost”，并且在错误堆栈跟踪中，构造方法没有将主机和端口数据传递给 PDO 类:

PDO->__construct('mysql:dbname=db_platform', 'root', '****')

我已经手动删除了缓存文件夹。

composer.json

"require": {
    "php": ">=5.3.3",
    "symfony/symfony": "2.1.0",
    "doctrine/orm": ">=2.3.0,<2.4.*-dev",
    "doctrine/doctrine-bundle": ">=2.1",
    "doctrine/mongodb": "1.0.1",
    "doctrine/mongodb-odm-bundle": "3.0.*",
    "twig/extensions": "1.0.*",
    "symfony/assetic-bundle": "2.1.*",
    "symfony/swiftmailer-bundle": "2.1.*", 
    "symfony/monolog-bundle": "2.1.*",
    "sensio/distribution-bundle": "2.1.*",
    "sensio/framework-extra-bundle": "2.1.*",
    "sensio/generator-bundle": "2.1.*",
    .... more
},

有什么建议吗？

提前致谢， 毛罗

我能找出问题所在，是 config.yml 中的 PDO 服务参数:

services:
    pdo:
        class: PDO
        arguments:
            - "mysql:host=%database_host%;port=%database_port%;dbname=%database_name%"
            - %database_user%
            - %database_password%

我必须添加主机和端口参数。

感谢您的回复。
