Nginx 502错误网关-Django-Gunicorn-运行MySQL报告(存储过程)的时间超过30秒

我在AWS上有Django，Nginx，Gunicorn和MySQL.

I have a Django, Nginx, Gunicorn, and MySQL on AWS.

运行来自django的回发，该回发调用了需要30秒钟以上才能完成的存储过程，从而导致返回"502 Bad Gateway" nginx/1.4.6(Ubuntu).

Running a postback from django which calls a stored procedure that takes longer than 30 seconds to complete causes a return of "502 Bad Gateway" nginx/1.4.6 (Ubuntu).

肯定看起来像是超时问题，并且此帖子应该可以解决该问题.

It sure looks like a timeout issue and that this post should resolve it.

但是可惜，它似乎没有用.

But alas, it doesn't seem to be working.

这是我的gunicorn.conf文件:

Here is my gunicorn.conf file:

description "Gunicorn application server handling formManagement django app"

start on runlevel [2345]
stop on runlevel [!2345]

respawn
setuid ubuntu
setgid www-data
chdir /home/ubuntu/AARC-ServiceManager/ServerSide/formManagement

exec ve/bin/gunicorn --timeout 300 --workers 3 --bind unix:/home/ubuntu/AARC-ServiceManager/ServerSide/formManagement/formManagement.sock formManagement.wsgi:application

还有我的Nginx.conf:

And my Nginx.conf:

user www-data;
worker_processes 4;
pid /run/nginx.pid;

events {
                worker_connections 768;
                # multi_accept on;
}

                include /etc/nginx/mime.types;

                access_log /var/log/nginx/access.log;
                error_log /var/log/nginx/error.log;

                ##

                ##

                gzip on;
                gzip_disable "msie6";


                include /etc/nginx/conf.d/*.conf;
                include /etc/nginx/sites-enabled/*;
}

有什么想法吗?

更新: 这是nginx错误日志中的错误: [错误] 14316#0:* 13上游过早关闭连接，同时从上游读取响应标头...

UPDATE: This is the error in the nginx error log: [error] 14316#0: *13 upstream prematurely closed connection while reading response header from upstream ...
