CakePHP 2.0:数据库连接"Mysql"丢失或无法创建

Question

在安装CakePHP 2.0之后(修改过,我说我在cakephp 2.0的干净安装上遇到同样的问题)我发现自己面临一个我无法解决的错误.

组态:

服务器:debian weezy 7

用户:测试

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

nginx配置

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配置

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

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

user = test
group = test

listen.allowed_clients = 127.0.0.1
listen.owner = test
listen.group = test
listen.backlog = -1
pm = dynamic
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3
pm.max_requests = 200
pm.status_path = /status_31337
request_terminate_timeout = 30s
catch_workers_output = yes
php_value[session.save_path] = /tmp

页面上的可见错误:

Database connection "Mysql" is missing, or could not be created.

Error: An Internal Error Has Occurred.

在mysql数据库凭据是正确的,用户mysql用户测试存在并完全访问测试.*

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'
    );
}

检查与CakePHP的配置文件的连接(在stackoverflow上找到的脚本)

<?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 table帖子:`

用php.ini检查套接字

*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

验证PDO扩展的存在.

var_dump( extension_loaded('pdo_mysql') );

return => bool(true)

我希望我提供了很多关于我的问题的信息.我愿意进行各种操作来测试.(我认为问题服务器端配置必然,虽然这个配置适用于连接到mysql的其他基本应用程序).

真诚.

在/app/Config/database.php文件中,更改以下行:

'host' => 'localhost',

至:

'host' => '127.0.0.1',
