带有 sf2、php-fpm 和 fastCGI 的 Nginx 配置文件

Question

这是我的配置文件，它取自官方 symfony 2 网站，因此它应该可以工作：

server {
    server_name domain.tld www.domain.tld;
    root /var/www/project/web;

    location / {
        # try to serve file directly, fallback to app.php
        try_files $uri /app.php$is_args$args;
    }
    # DEV
    # This rule should only be placed on your development environment
    # In production, don't include this and don't deploy app_dev.php or config.php
    location ~ ^/(app_dev|config)\.php(/|$) {
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_split_path_info ^(.+\.php)(/.*)$;
        include fastcgi_params;
        # When you are using symlinks to link the document root to the
        # current version of your application, you should pass the real
        # application path instead of the path to the symlink to PHP
        # FPM.
        # Otherwise, PHP's OPcache may not properly detect changes to
        # your PHP files (see https://github.com/zendtech/ZendOptimizerPlus/issues/126
        # for more information).
        fastcgi_param  SCRIPT_FILENAME  $realpath_root$fastcgi_script_name;
        fastcgi_param DOCUMENT_ROOT $realpath_root;
    }
    # PROD
    location ~ ^/app\.php(/|$) {
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_split_path_info ^(.+\.php)(/.*)$;
        include fastcgi_params;
        # When you are using symlinks to link the document root to the
        # current version of your application, you should pass the real
        # application path instead of the path to the symlink to PHP
        # FPM.
        # Otherwise, PHP's OPcache may not properly detect changes to
        # your PHP files (see https://github.com/zendtech/ZendOptimizerPlus/issues/126
        # for more information).
        fastcgi_param  SCRIPT_FILENAME  $realpath_root$fastcgi_script_name;
        fastcgi_param DOCUMENT_ROOT $realpath_root;
        # Prevents URIs that include the front controller. This will 404:
        # http://domain.tld/app.php/some-path
        # Remove the internal directive to allow URIs like this
        internal;
    }

    error_log /var/log/nginx/project_error.log;
    access_log /var/log/nginx/project_access.log;
}

输入www.domain.com/工作正常，但任何其他路线都会引发 500 错误（当执行第二/第三个位置块时）。

我试过：

www.domain.com/test/
www.domain.com/app.php/test/
www.domain.com/app_dev.php/test/ (can't access app.dev.php error)
www.domain.com/web/app.php/test/

都不起作用。

当我输入这些地址时，我也没有得到邻居 nginx 或应用程序日志（/路由按预期创建日志）。

如果是代码的错误，我会得到一些日志，不是吗？

出了什么问题？我不知道如何跟踪这些错误，我无法创建工作配置。
