我得到这样的错误:

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

当前回答

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;
 # ........
}

其他回答

我有这个错误,我找到了3种方法来修复它:

在.env: https://stackoverflow.com/a/69321273/13653732中设置shell_verbose =0或另一个< 3的值。在这种情况下,您将禁用PHP日志,但它们对开发和调试很有用。 fastcgi设置。在php.ini中Logging =0。与上述结果相同。 将Symfony从5.2更新到5.3。我认为旧版本在这方面有问题。

所有的PHP Symfony日志都被认为是Nginx的错误,但PHP工作正常。

我有Nginx 1.17, PHP 8.0.2, PHP- fpm, Symfony 5.2, Xdebug, Docker。

我尝试了新版本Nginx 1.21, PHP 8.0.14,但没有任何结果。这个问题不在于Apache。

我改变了Nginx的配置,但也没有任何结果。

如果nginx作为代理/反向代理运行

也就是说,对于ngx_http_proxy_module的用户

除了fastcgi,代理模块还将请求头保存在临时缓冲区中。

所以你可能还需要增加proxy_buffer_size和proxy_buffers,或者完全禁用它(请阅读nginx文档)。

代理缓存配置示例

http {
  proxy_buffer_size   128k;
  proxy_buffers   4 256k;
  proxy_busy_buffers_size   256k;
}

禁用代理缓冲区的示例(推荐用于长轮询服务器)

http {
  proxy_buffering off;
}

欲了解更多信息:Nginx代理模块文档

upstream在读取upstream的响应头时发送了太大的头,这是nginx表示“我不喜欢我所看到的”的通用方式。

上游服务器线程崩溃 上游服务器发回无效报头 从STDERR发送回来的通知/警告溢出了它们的缓冲区,它和STDOUT都被关闭

3:查看消息上面的错误日志,它是否与消息前面的日志行一起流?PHP声明:未定义的索引: 示例片段从循环我的日志文件:

2015/11/23 10:30:02 [error] 32451#0: *580927 FastCGI sent in stderr: "PHP message: PHP Notice:  Undefined index: Firstname in /srv/www/classes/data_convert.php on line 1090
PHP message: PHP Notice:  Undefined index: Lastname in /srv/www/classes/data_convert.php on line 1090
... // 20 lines of same
PHP message: PHP Notice:  Undefined index: Firstname in /srv/www/classes/data_convert.php on line 1090
PHP message: PHP Notice:  Undefined index: Lastname in /srv/www/classes/data_convert.php on line 1090
PHP message: PHP Notice:  Undef
2015/11/23 10:30:02 [error] 32451#0: *580927 FastCGI sent in stderr: "ta_convert.php on line 1090
PHP message: PHP Notice:  Undefined index: Firstname

在从底部开始的第3行中,您可以看到缓冲区限制被击中,破坏了,下一个线程在它上面写入。然后Nginx关闭连接并返回502给客户端。

2:记录每个请求发送的所有报头,检查它们并确保它们符合标准(nginx不允许任何超过24小时的内容删除/过期cookie,发送无效的内容长度,因为错误消息在内容计数之前被缓冲了…)Getallheaders函数调用通常可以在抽象的代码情况下帮助解决PHP获取所有头文件的问题

例子包括:

<?php
//expire cookie
setcookie ( 'bookmark', '', strtotime('2012-01-01 00:00:00') );
// nginx will refuse this header response, too far past to accept
....
?>

这:

<?php
header('Content-type: image/jpg');
?>

<?php   //a space was injected into the output above this line
header('Content-length: ' . filesize('image.jpg') );
echo file_get_contents('image.jpg');
// error! the response is now 1-byte longer than header!!
?>

1:验证,或做一个脚本日志,以确保您的线程到达正确的终点,并在完成之前不退出。

我有一个django应用程序部署到EBS,我使用Python 3.8运行在64bit亚马逊Linux 2上。下面的方法适用于我(注意,如果您使用的是以前的Linux版本,文件夹结构可能会有所不同。欲了解更多信息,请参阅这里的官方文档

创建.platform文件夹及其子目录,如下所示:

|-- .ebextensions          # Don't put nginx config here
|   |-- django.config        
|-- .platform              # Make ".platform" folder and its subfolders
    |-- nginx                
    |   -- conf.d
    |       -- proxy.conf

请注意,proxy.conf文件应该放在.platform文件夹中,而不是.ebextensions文件夹或.elasticbeanstalk文件夹中。扩展名应该以.conf而不是.config结尾。

在proxy.conf文件中,直接复制并粘贴这些行:

client_max_body_size 50M;
large_client_header_buffers 4 32k;
fastcgi_buffers 16 32k;
fastcgi_buffer_size 32k;
proxy_buffer_size   128k;
proxy_buffers   4 256k;
proxy_busy_buffers_size   256k;

不需要发出命令重新启动nginx(适用于Amazon Linux 2)

再次将源代码部署到elastic beanstalk。

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;
