Question

我对Symfony2有疑问。一切正常，有一天......开始出现问题......

当我打开一个页面时，我收到错误500.服务器返回此错误，而不是Symfony。如果我刷新，我显示页面没有错误。但是，当我打开一个新页面（新网址，同一网站）时，错误再次出现。

我试图重新加载apache。我尝试删除缓存和日志中的所有内容。我的控制台文件，app.php文件，app_dev.php文件已取消注释umask（0000）。

当我遇到错误时，这是symfony2日志的最后一行：

apache错误日志：

[Fri Sep 04 11:24:49 2015] [error] [client my.ip.here] Premature end of script headers: app_dev.php

当我使用app.php

时，prod中不存在这个问题

syslog没有关于此的内容。我在同一台服务器上的其他网站上没有问题。我没有硬盘空间问题。

有人有想法吗？ THX

app_dev.php文件：

<?php


use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Debug\Debug;


// If you don't want to setup permissions the proper way, just uncomment the following PHP line
// read http://symfony.com/doc/current/book/installation.html#configuration-and-setup for more information
umask(0000);

// This check prevents access to debug front controllers that are deployed by accident to production servers.
// Feel free to remove this, extend it, or make something more sophisticated.
if (isset($_SERVER['HTTP_CLIENT_IP'])
    || isset($_SERVER['HTTP_X_FORWARDED_FOR'])
    || !in_array(@$_SERVER['REMOTE_ADDR'], array('127.0.0.1', 'xxx.xxx.xxx.xxx'))
) {
    header('HTTP/1.0 403 Forbidden');
    exit($_SERVER['REMOTE_ADDR'].' : You are not allowed to access this file. Check '.basename(__FILE__).' for more information.');
}

$loader = require_once __DIR__.'/../app/bootstrap.php.cache';
Debug::enable();

require_once __DIR__.'/../app/AppKernel.php';

$kernel = new AppKernel('dev', true);
$kernel->loadClassCache();
$request = Request::createFromGlobals();
$response = $kernel->handle($request);
$response->send();
$kernel->terminate($request, $response);

对于apache配置，它是isp配置配置，我刚为此网站添加了这个：

Apache指令：

DocumentRoot /var/www/clients/client2/web56/web/symfony/web/
FcgidMaxRequestLen 20000000

php.ini：

apc.shm_size = 256M
realpath_cache_size = 4096k
realpath_cache_ttl=7200
session.auto_start = 0
xdebug.remote_autostart=0
xdebug.remote_enable=0
xdebug.profiler_enable=0

在config_dev.yml中，如果我从monolog配置中删除firephp和chromephp，问题就解决了。我不认为这是一个很好的解决方案，任何人都有其他想法？

我在 config_dev.yml 中评论了 firephp 和 chromephp ：

imports:
    - { resource: config.yml }

framework:
    router:
        resource: "%kernel.root_dir%/config/routing_dev.yml"
        strict_requirements: true
    profiler: { only_exceptions: false }

web_profiler:
    toolbar: true
    intercept_redirects: false

monolog:
    handlers:
        main:
            type:  stream
            path:  "%kernel.logs_dir%/%kernel.environment%.log"
            level: debug
#        firephp:
#            type:  firephp
#            level: info
#        chromephp:
#            type:  chromephp
#            level: info

assetic:
    use_controller: true

#swiftmailer:
#    delivery_address: me@example.com

Symfony2 app_dev.php only error 500脚本过早结束
