Nginx + PHP-FPM 7.1-504网关超时

Question

我在synology nas上将nginx 1.12和php-fpm 7.1作为单独的docker容器运行，并且如果php-
script运行时间超过60s，则会收到504 Gateway错误。我已经尝试了几个nginx配置参数，但是错误仍然存​​在。

这是我实际的nginx配置：

#user  www-data;
#group http
worker_processes  1;

error_log  /opt/data/logs/nginx_error.log notice;

events {
    worker_connections  1024;
}

http {
    include       mime.types;
    default_type  application/octet-stream;

    #keepalive_timeout 30s;
    sendfile on;
    #tcp_nopush off;
    tcp_nodelay on;

    #gzip  off;

    send_timeout 300

    server {
        listen       80;
        server_name  "";

        root   /opt/php;
        index  index.php;

        location /data/ {
           sendfile        on;
           root   /opt;
        }

        location ~ \.php$ {

            include fastcgi_params;

            fastcgi_split_path_info ^(.+?\.php)(/.*)$;
            if (!-f $document_root$fastcgi_script_name) {
                return 404;
            }

            # Mitigate https://httpoxy.org/ vulnerabilities
            fastcgi_param HTTP_PROXY "";

            fastcgi_pass   php:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            fastcgi_read_timeout 300;
            #fastcgi_buffering off;
            #fastcgi_keep_conn on;
            #fastcgi_intercept_errors on;
            #fastcgi_cache  off;
            #fastcgi_ignore_client_abort on;

        }

        location ~ ^/(status|ping)$ {
             access_log off;
             include fastcgi_params;
             fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
             fastcgi_pass php:9000;
         }
    }

}

php-testscript：

<?php 
sleep(65);
echo "done!";
file_put_contents("/opt/data/timetest.txt", "\nEnd", FILE_APPEND);

60秒后，浏览器显示504网关超时。php脚本仍在运行，并且还在将文本写入文件。

Nginx错误日志：

2017/07/22 08:16:32 [error] 8#8: *10 upstream timed out (110: Connection timed out) while reading response header from upstream, client: 172.17.0.1, server: , request: "GET /timetest.php HTTP/1.1", upstream: "fastcgi://172.17.0.3:9000", host: "192.168.0.100:8081"

有人知道吗？

问题可能是为什么您的后端需要这么长时间才能做出响应？不确定您的用例，但通常等待很长一段时间才能获得响应并不友好。

回答您的问题：

我找到了此链接：https : //easyengine.io/tutorials/php/increase-script-execution-
time/

添加在/etc/php5/fpm/php.ini中

max_execution_time = 300

在/etc/php5/fpm/pool.d/www.conf中设置

request_terminate_timeout = 300

在/etc/nginx/nginx.conf中设置

http {
 #...
 fastcgi_read_timeout 300;  
 #...
}

并在您的配置中：

location ~ \.php$ {
 include /etc/nginx/fastcgi_params;
 fastcgi_pass unix:/var/run/php5-fpm.sock;
 fastcgi_read_timeout 300;
}

并重装服务

service php5-fpm reload
service nginx reload
