Nginx php-fpm 504网关错误

经过几个小时的搜索和调试后我放弃了！

关于长时间运行的 PHP 进程有成千上万个问题和文章，但没有一个能解决我的问题。

我有一个包含以下代码的 PHP 脚本：

$cur = 0; 
    // Second, loop for $timeout seconds checking if process is running 
    while( $cur < 31 ) { 
        sleep(1); 
        $cur += 1; 

       echo "\n ---- $cur ------ \n";
    }

它只是旨在运行 31 秒。

我有一个 Nginx，在 debian 服务器中将 PHP 配置为 fastcgi。

我设置了 max_execution_time = 600

在

/etc/php5/fpm/php.ini

我甚至把它放在

/etc/php5/cli/php.ini

还设置

request_terminate_timeout = 600

在 /etc/php5/fpm/pool.d/www.conf 中

我还在 nginx.conf http 部分做了这些更改

client_header_timeout   600;
client_body_timeout     600;
send_timeout           600;

fastcgi_read_timeout    600;
fastcgi_send_timeout    600;
client_max_body_size    20m;
fastcgi_buffers         8 128k;
fastcgi_buffer_size     128k;

并将指令放在服务器部分内。这些指令放在 nginx 配置的位置部分内

send_timeout           600;

fastcgi_read_timeout    600;
fastcgi_send_timeout    600;
client_max_body_size    20m;
fastcgi_buffers         8 128k;
fastcgi_buffer_size     128k;

但我仍然在浏览器中遇到网关超时错误！（是的！我重启了 php-fpm 和 nginx 数千次）

你们有什么想法吗？

这是我的 nginx.conf

答案1

尝试告诉 nginx 在脚本运行时禁用输出缓冲：

header('X-Accel-Buffering: no');

话虽如此，我刚刚用一个相当普通的 nginx apache 代理尝试了你的确切示例，除了等待 php 脚本终止后再显示它之外，没有遇到任何问题。

答案2

该错误来自 Nginx，而不是 PHP-FPM。Nginx 抱怨它在 60 秒内没有收到任何内容，这是默认超时时间。 你可以改变它：

fastcgi_read_timeout 600s;
