Question

我正在部署我的symfony2项目，而且我遇到了与远程mysql服务器的数据库连接问题。似乎symfony仍然试图连接到本地mysql实例（使用socket而不是tcp）并且没有考虑parameteres.yml哪里是正确的设置。

parameters.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（当我尝试清除缓存或通过http浏览器时由控制台显示）

PDOException: SQLSTATE[28000] [1045] Access denied for user 'root'@'localhost' (using password: YES)
in /var/www/Symfony/app/cache/dev/appDevDebugProjectContainer.php line 2336
at PDO->__construct('mysql:dbname=db_platform', 'root', '****') in /var/www/Symfony/app/cache/dev/appDevDebugProjectContainer.php line 2336

at Container->get('session') in /var/www/Symfony/vendor/symfony/symfony/src/Symfony/Bundle/FrameworkBundle/EventListener/SessionListener.php line 52
........

如上所示，配置文件中没有“localhost”，错误堆栈跟踪中的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，莫罗

Answer 1

我可以找出问题，它是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。

感谢您的回复莫罗

Answer 2

在较新版本的symfony（> 3）上，您可以简单地进行操作（在.env文件中）：

DATABASE_URL=mysql://mysql_user_name:your_password@www.theHost.domainName:3306/your_database

带有doctrine的symfony2无法连接到远程mysql数据库
