从上游读取响应报头时，上游发送了太大的报头

我得到这样的错误:

2014/05/24 11:49:06 [error] 8376#0: *54031 upstream sent too big header while reading response header from upstream, client: 107.21.193.210, server: aamjanata.com, request: "GET /the-brainwash-chronicles-sponsored-by-gujarat-government/,%20https:/aamjanata.com/the-brainwash-chronicles-sponsored-by-gujarat-government/,%20https:/aamjanata.com/the-brainwash-chronicles-sponsored-by-gujarat-government/,%20https:/aamjanata.com/the-brainwash-chronicles-sponsored-by-gujarat-government/,%20https:/aamjanata.com/the-brainwash-chronicles-sponsored-by-gujarat-government/,%20https:/aamjanata.com/the-brainwash-chronicles-sponsored-by-gujarat-government/,%20https:/aamjanata.com/the-brainwash-chronicles-sponsored-by-gujarat-government/,%20https:/aamjanata.com/the-brainwash-chronicles-sponsored-by-gujarat-government/,%20https:/aamjanata.com/the-brainwash-chronicles-sponsored-by-gujarat-government/,%20https:/aamjanata.com/the-brainwash-chronicles-sponsored-by-gujarat-government/,%20https:/aamjanata.com/the-brainwash-chronicles-sponsored-by-gujarat-government/,%20https:/aamjanata.com/the-brainwash-chronicles-sponsored-by-gujarat-government/,%20https:/aamjanata.com/the-brainwash-chronicles-sponsored-by-gujarat-government/,%20https:/aamjanata.com/the-brainwash-chronicles-sponsored-by-gujarat-government/,%20https:/aamjanata.com/the-brainwash-chronicles-sponsored-by-gujarat-government/,%20https:/aamjanata.com/the-brainwash-chronicles-sponsored-by-gujarat-government/,%20https://aamjanata.com/the-brainwash-chronicles-sponsored-by-gujarat-government/,%20https:/aamjanata.com/the-brainwash-chronicles-sponsored-by-gujarat-government/,%20https:/aamjanata.com/the-brainwash-chronicles-sponsored-by-gujarat-government/,%20https:/aamjanata.com/the-brainwash-chronicles-sponsored-by-gujarat-government/,%20https:/aamjanata.com/the-brainwash-chronicles-sponsored-by-gujarat-government/,%20https:/aamjanata.com/the-brainwash-chronicles-sponsored-by-gujarat-government/,%20https:/aamjanata.com/the-brainwash-chronicles-sponsored-by-gujarat-government/,%20ht

总是一样的。一个url重复使用逗号分隔。不知道是什么引起的。有人知道吗?

更新:另一个错误:

http request count is zero while sending response to client

这是配置。还有其他不相关的东西，但这部分是添加/编辑的

fastcgi_cache_path /var/nginx-cache levels=1:2 keys_zone=WORDPRESS:100m inactive=60m;
fastcgi_cache_key "$scheme$request_method$host$request_uri";

            #this should match value of "listen" directive in php-fpm pool
            server unix:/var/run/php5-fpm.sock;
    }

然后在服务器块中: 设置$skip_cache 0;

    # POST requests and urls with a query string should always go to PHP
    if ($request_method = POST) {
            set $skip_cache 1;

    location ~ \.php$ {

            include fastcgi_params;

当前回答

fastcgi_busy_buffers_size 512k;
fastcgi_buffer_size 512k;
fastcgi_buffers 16 512k;

当我增加数字时，它对我有用

其他回答

我不确定这个问题与php发送的头文件有关。确保缓冲已启用。简单的方法是创建一个proxy.conf文件:

proxy_redirect          off;
proxy_set_header        Host            $host;
proxy_set_header        X-Real-IP       $remote_addr;
proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
client_max_body_size    100m;
client_body_buffer_size 128k;
proxy_connect_timeout   90;
proxy_send_timeout      90;
proxy_read_timeout      90;
proxy_buffering         on;
proxy_buffer_size       128k;
proxy_buffers           4 256k;
proxy_busy_buffers_size 256k;

和一个fasci .conf文件:

fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;
fastcgi_param  QUERY_STRING       $query_string;
fastcgi_param  REQUEST_METHOD     $request_method;
fastcgi_param  CONTENT_TYPE       $content_type;
fastcgi_param  CONTENT_LENGTH     $content_length;
fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
fastcgi_param  REQUEST_URI        $request_uri;
fastcgi_param  DOCUMENT_URI       $document_uri;
fastcgi_param  DOCUMENT_ROOT      $document_root;
fastcgi_param  SERVER_PROTOCOL    $server_protocol;
fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
fastcgi_param  SERVER_SOFTWARE    nginx/$nginx_version;
fastcgi_param  REMOTE_ADDR        $remote_addr;
fastcgi_param  REMOTE_PORT        $remote_port;
fastcgi_param  SERVER_ADDR        $server_addr;
fastcgi_param  SERVER_PORT        $server_port;
fastcgi_param  SERVER_NAME        $server_name;
fastcgi_buffers 128 4096k;
fastcgi_buffer_size 4096k;
fastcgi_index  index.php;
fastcgi_param  REDIRECT_STATUS    200;

接下来你需要在默认配置服务器中调用它们，如下所示:

http {
  include    /etc/nginx/mime.types;
  include    /etc/nginx/proxy.conf;
  include    /etc/nginx/fastcgi.conf;
  index    index.html index.htm index.php;
  log_format   main '$remote_addr - $remote_user [$time_local]  $status '
    '"$request" $body_bytes_sent "$http_referer" '
    '"$http_user_agent" "$http_x_forwarded_for"';
  #access_log   /logs/access.log  main;
  sendfile     on;
  tcp_nopush   on;
 # ........
}

在php-fpm和nginx的docker容器中运行Symfony应用程序时也遇到了同样的问题。

经过一些研究发现，这是由php-fpm的stderr写入nginx日志引起的。例如，php警告(在Symfony调试模式中大量生成)在docker日志php-fpm中重复:

[09-Jul-2021 12:25:46] WARNING: [pool www] child 38 said into stderr: ""

[09-Jul-2021 12:25:46] WARNING: [pool www] child 38 said into stderr: ""

和docker日志nginx:

2021/07/09 12:25:46 [error] 30#30: *2 FastCGI sent in stderr: "ller" to listener "OblgazAPI\API\Common\Infrastructure\EventSubscriber\LegalAuthenticationChecker::checkAuthentication".

PHP message: [debug] Notified event "kernel.exception" to listener "Symfony\Component\HttpKernel\EventListener\ProfilerListener::onKernelException".

然后nginx log以

2021/07/09 12:25:46 [error] 30#30: *2 upstream sent too big header while reading response header from upstream ...

我得到了502个错误。

增加nginx配置中的fastcgi_buffer_size是有帮助的，但这似乎更像是抑制问题，而不是治疗。

一个更好的解决方案是禁用php-fpm通过FastCGI发送日志。发现它可以通过设置fastcgi来实现。在PHP .ini中Logging =0(默认为1)。

在将其更改为0后，问题就消失了，nginx日志看起来更干净了。

172.18.0.1 - - [09/Jul/2021:12:36:02 +0300] "GET /my/symfony/app HTTP/1.1" 401 73 "-" "PostmanRuntime/7.26.8"
172.18.0.1 - - [09/Jul/2021:12:36:04 +0300] "GET /my/symfony/app HTTP/1.1" 401 73 "-" "PostmanRuntime/7.26.8"

并且所有的php-fpm日志仍然在它们在php-fpm日志中的位置。

Plesk指令

我把上面两个答案结合起来

在Plesk 12中，我让nginx作为反向代理运行(我认为这是默认的)。因此，当前顶部的答案不工作，因为nginx也作为代理运行。

我进入订阅|[订阅域]|网站和域(选项卡)|[虚拟主机域]| Web服务器设置。

然后在该页的底部，你可以设置附加nginx指令，我设置为上面两个答案的组合:

fastcgi_buffers         16  16k;
fastcgi_buffer_size         32k;
proxy_buffer_size          128k;
proxy_buffers            4 256k;
proxy_busy_buffers_size    256k;

如果你使用Symfony框架: 在搞砸Nginx配置之前，先禁用ChromePHP。

1 -打开app/config/config_dev.yml

注释这些行:

#chromephp:
    #type:   chromephp
    #level:  info

ChromePHP将调试信息json编码在X-ChromePhp-Data头文件中，这对于使用fastcgi的nginx的默认配置来说太大了。

在我们的例子中，我们得到了这个nginx错误，因为我们的后端生成了一个非常长的URL重定向响应:

HTTP/1.1 301 Moved Permanently 
Location: https://www.example.com/?manyParamsHere...

出于好奇，我们将这个大URL保存到一个文件中，它的大小为4.4 Kb。

在配置文件/etc/nginx/conf.d/some_site.conf中添加两行帮助我们修复了这个错误:

server {
    # ...
    location ~ ^/index\.php(/|$) {
        fastcgi_pass php-upstream;
        fastcgi_split_path_info ^(.+\.php)(/.*)$;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

        # Add these lines:
        fastcgi_buffer_size 32k;
        fastcgi_buffers 4 32k;
    }
}

在nginx官方文档中阅读更多关于这些参数的信息。
