php未找到子目录的Apache2服务器

我正试图在我的DigitalOcean服务器上部署一个PHP应用程序，运行带有apache2和php5的Ubuntu 14.04

首先让我提到，该应用程序使用内置的php服务器在localhost上运行得非常完美

通过访问“site.com/”我可以毫无问题地访问index.php，但它在其他每个php文件上都会显示404。直接访问site.com/index.php时，我也会得到404 我的应用程序使用一个简单的PHP路由器重定向到处理视图的控制器

apache服务器设置为指向/var/www/my_site/public

这是文件结构：

这是我的index.php：

<?php
use App\Core\Autoloader;
use App\Core\Container;
use App\Core\Router;
/*************

error_reporting(-1);
// dev only
ini_set('display_errors', 1);
define('SCRIPT_DEBUG', true);
define('VIEW_DIR', realpath(__DIR__ . '/../views'));
define('CONFIG_DIR', realpath(__DIR__ . '/../config/'));
/***********

session_start();
require __DIR__ . '/../App/Core/Autoloader.php';
require CONFIG_DIR . '/db.php';
$dbh = new PDO('mysql:host=127.0.0.1;dbname=' . $db_name, $db_user, $db_pass);
$dbh->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
$loader = new Autoloader();
$loader->addNamespace('App', __DIR__ . '/../App');
$loader->register();
$container = new Container();
$container->bindArguments('App\\Model\\User',   ['dbh' => $dbh]);
$container->bindArguments('App\\Model\\Image',  ['dbh' => $dbh]);

$router = new Router();
$router->addRoute('GET', '/',               ['App\\Controller\\SessionController', "redirect"   ]);
$router->addRoute('GET', '/log_in',         ['App\\Controller\\SessionController', "newSession" ]);

$router->addRoute('GET', '/users' ,         ['App\\Controller\\UserController',    "users"      ]);
$router->addRoute('GET', '/upload',         ['App\\Controller\\ImageController',   "upload"     ]);
$router->addRoute('GET', '/gallery',        ['App\\Controller\\ImageController',   "gallery"    ]);

$router->addRoute('POST', '/delete_user',   ['App\\Controller\\UserController',    "destroy"    ]);
$router->addRoute('POST', '/edit_user',     ['App\\Controller\\UserController',    "update"     ]);
$router->addRoute('POST', '/upload',        ['App\\Controller\\ImageController',   "save"       ]);
$router->addRoute('POST', '/delete_image',  ['App\\Controller\\ImageController',   "destroy"    ]);
// Convert i.e. "/foo%40bar?id=1" to "/foo@bar"
$uri = rawurldecode(parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH));
$route = $router->match($_SERVER['REQUEST_METHOD'], $uri);
if ($route === null) {
    $route = [
    'handle' => ['App\\Controller\\ErrorController', 'error404'],
    'arguments' => []
    ];
}
$controller = $container->create($route['handle'][0]);
$container->call([$controller, $route['handle'][1]], $route['arguments']);

在url中使用index.php时index.php是否正常工作，或者仅当路径为空且使用默认目录索引路径时，是否正常工作？实际上否，我只能访问“/”。但是如果我输入/index.php，它会触发我自己的ErrorController，它会显示一个“更漂亮”的404页面。其他路线都不起作用，但您是否打印了$route以查看其价值？
