Troubleshooting "No such file or directory" when running `php app/console doctrine:schema:create`

Question

I am new to Symfony2 (beta4) and Doctrine and am having issues when i try to create the DB schema via command line.

Here's the error:

$ php app/console doctrine:schema:create

Creating database schema...

[PDOException]                                    
SQLSTATE[HY000] [2002] No such file or directory  

[ErrorException]                                                                                          
Warning: PDO::__construct(): [2002] No such file or directory (trying to connect via unix:///var/mysql/mysql.sock) 
in /Applications/MAMP/htdocs/sf-test-2/vendor/doctrine-dbal/lib/Doctrine/DBAL/Driver/PDOConnection.php line 36

The mysql database settings are correctly inserted in the config/parameters.ini file.

And here's the Doctrine configuration in config.yml

# Doctrine Configuration
doctrine:
    dbal:
        driver:   %database_driver%
        host:     %database_host%
        dbname:   %database_name%
        user:     %database_user%
        password: %database_password%

    orm:
        auto_generate_proxy_classes: %kernel.debug%
        auto_mapping: true

And the entity (i made only one to test it)

<?php
// src/Acme/NewsBundle/Entity/Article.php
namespace Acme\NewsBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity
 * @ORM\Table(name="articles")
 */
class Article
{
    /**
     * @ORM\Id
     * @ORM\Column(type="integer")
     * @ORM\GeneratedValue(strategy="AUTO")
     */
protected $id;

/**
 * @ORM\Column(type="string", length="255")
 */
protected $title;

/**
 * @ORM\Column(type="text")
 */
protected $body;

/**
 * @ORM\Column(type="string", length="255")
 */
protected $author;

/**
 * @ORM\Column(type="date")
 */
protected $date;
}
?>

Answer 1

Too late but I hope it can help someone.

Just today I fall into a similar situation (but in other context, I was trying to create entities from db).

I solved it simply modifying de database_host from "localhost" to "127.0.0.1" in the parameters.ini file.

I think my Mysql instance is running only via TCP and not socket and because this when use database_host="localhost" it fails.

Try to add this line

unix_socket: /tmp/mysql.sock

into your config.yml file > doctrine > dbal just after the password line.
