Nginx 502 Bad Gateway错误仅在Firefox中 [英] Nginx 502 Bad Gateway error ONLY in Firefox

问题描述

我在本地运行一个网站，所有流量都通过NGinx路由，然后将对PHP页面的请求分派到Apache并提供静态文件.在Chrome，Safari，IE等操作系统中完美运行.

I am running a website locally, all the traffic is routed through NGinx which then dispatches requests to PHP pages to Apache and serves static files. Works perfectly in Chrome, Safari, IE, etc.

但是，每当我在Firefox中打开网站时，都会出现以下错误:

However, whenever I open the website in Firefox I get the following error:

502 Bad Gateway
nginx/0.7.65

如果我清除缓存和cookie，然后重新启动FireFox，则能够在错误返回之前加载该站点一次或两次.我已经尝试了Firefox 3.6和Firefox 3.5，并且都遇到相同的问题.

If I clear out cache and cookies, and then restart FireFox, I am able to load the site once or twice before the error returns. I've tried both Firefox 3.6 and 3.5 and both have the same problem.

这是我的Nginx配置的样子:

Here is what my Nginx config looks like:

worker_processes  2;

events {
    worker_connections  1024;
}


http {

 server {
     listen        80;
     server_name   local.mysite.amc;
     root          /Users/joshmaker/Sites/mysite;

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

     location / {
         proxy_set_header Host $host;
         proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
         proxy_pass http://local.mysite.amc:8080;
     }

  include /opt/local/etc/nginx/rewrite.txt;
 }
 server {  
  include /opt/local/etc/nginx/mime.types;

     listen        80;
     server_name   local.static.mysite.amc;
     root          /Users/joshmaker/Sites/mysite;

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

这是Firefox在我的error.log文件中生成的错误:

And here is the errors that Firefox generates in my error.log file:

[error] 11013#0: *26 kevent() reported that connect() failed (61: Connection refused) while connecting to upstream     
[error] 11013#0: *30 upstream sent too big header while reading response header from upstream
[error] 11013#0: *30 no live upstreams while connecting to upstream

我完全不知道为什么浏览器会导致服务器错误.有人可以帮忙吗?

I am completely at a loss why a browser would cause a server error. Can someone help?

推荐答案

我似乎找到了解决该问题的方法.在Google进行了一些其他研究之后，我在Nginx配置中添加了以下几行:

I seem to have found a work around that fixed my problem. After some additional Google research, I added the following lines to my Nginx config:

proxy_buffers 8 16k;
proxy_buffer_size 32k;

但是，我仍然不知道为什么为什么有效，以及为什么只有Firefox似乎有问题.如果有人可以阐明这一点，或提供更好的解决方案，将不胜感激！

However, I still don't know why this worked and why only Firefox seemed to have problems. If anyone can shed light on this, or offer a better solution, it would be much appreciated!
