CakePHP 2.0 : Database connection "Mysql" is missing, or could not be created

Question

following the installation of CakePHP 2.0 (modified, I said that I get the same problem on a clean install of cakephp 2.0) I found myself facing an error I have not been able to solve.

configuration:

server : debian weezy 7

user : test

structure : /wwwjail/siteroot/test/htdocs/[app/...]

nginx configuration

cat /etc/nginx/sites-available/test

server {
    listen IP:80 default;
    server_name domain.fr;
    access_log /var/log/nginx/test.access.log;
    error_log  /var/log/nginx/test.error.log;

    autoindex off;
    index index.php index.html;
    root /wwwjail/siteroot/test/htdocs/;

    location ~ \.php$ {
                        try_files $uri =404;

                        fastcgi_intercept_errors on;
                        fastcgi_pass unix:/wwwjail/siteroot/test/php-fpm.sock;

                        include /etc/nginx/fastcgi_params;
                        fastcgi_param SCRIPT_FILENAME $fastcgi_script_name;
    }
}

php5-fpm configuration

cat /etc/php5/fpm/pool.d/test.conf

[test]
listen = /wwwjail/siteroot/test/php-fpm.sock
chroot = /wwwjail/siteroot/test/htdocs

On the mysql database credentials are correct, the user mysql user-test exist and full access to test.*

cat /wwwjail/siteroot/test/htdocs/app/Config/database.php

class DATABASE_CONFIG {

    public $default = array(
        'datasource' => 'Database/Mysql',
        'persistent' => false,
        'host' => '127.0.0.1',
        'login' => 'user-test',
        'password' => 'mypassword',
        'database' => 'test',
        'prefix' => '',
        'encoding' => 'utf8'
    );
}

Checking the connection with the config file of CakePHP (script found on stackoverflow)

<?php
include("app/Config/database.php");
$config= new DATABASE_CONFIG();

$name = 'default';

$settings=$config->{$name};
$dsn = 'mysql:dbname='.$settings['database'].';host='.$settings['host'];
$user = $settings['login'];
$password = $settings['password'];

try {
    $dbh = new PDO($dsn, $user, $password);
    echo "Connection succeeded with dsn: ". $dsn . "\n";
    $sql = 'SELECT id, title FROM posts';
    echo "Here is the contents of the table `posts:";
    foreach ($dbh->query($sql) as $row) {
        print $row['id'] . "\t" . $row['title'] . "\n";
    }
} catch (PDOException $e) {
    echo 'PDO error: ' . $e->getMessage();
}

?>

====> return: Connection succeeded with dsn: mysql:dbname=test;host=127.0.0.1 Here is the contents of the tableposts:`

Checking socket with php.ini

*grep -i 'default_socket' /etc/php5/fpm/php.ini*

default_socket_timeout = 60
pdo_mysql.default_socket= /wwwjail/var/run/mysqld/mysqld.sock
mysql.default_socket = /wwwjail/var/run/mysqld/mysqld.sock 
mysqli.default_socket = /wwwjail/var/run/mysqld/mysqld.sock

Verification of the existence of the PDO extension.

var_dump( extension_loaded('pdo_mysql') );

return => bool(true)

I hope I have provided much information about my problem. I am willing to perform various manipulations to test. (I think a problem server side configuration necessarily, although this configuration works for other basic applications connecting to mysql also).

Sincerely.

In your /app/Config/database.php file, change the following line:

'host' => 'localhost',

to:

'host' => '127.0.0.1',
