Nginx配置502错误的网关错误 [英] Nginx configuration 502 bad gateway error

问题描述

我已配置/启用了运行的nginx网站:

I have a configured nginx sites enabled/available that when I run:

nginx -t

我获得了成功的测试，并且在以下时间获得了

I get a successful test and when I:

service nginx restart
thin restart -s 1

我的502错误消失了，但仅持续了十秒钟，然后再次出现.我的网站可用:

My 502 error goes away but only for ten seconds and then it shows up again. my sites-available is:

upstream myapp {
server 0.0.0.0:3000;

}

服务器{ 默认听80;

server { listen 80 default;

access_log /webservices/crawler/log/access.log;
error_log /webservices/crawler/error.log;

root   /webservices/crawler/public/;
index  index.html;

client_max_body_size 500M;

location / {
    proxy_set_header  X-Real-IP  $remote_addr;
    proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_redirect off;

    if (-f $request_filename/index.html) {
        rewrite (.*) $1/index.html;
        break;
    }

    if (-f $request_filename.html) {
        rewrite (.*) $1.html;
        break;
    }

    if (!-f $request_filename) {
        proxy_pass http://myapp;
        break;
    }
}

}

有人知道为什么我的配置只能工作几秒钟吗?谢谢您的帮助，如果您需要查看其他代码，请告诉我.

Does anyone know why my config only works for a few seconds? Thank you for any help and just let me know if you need to see any of my other code.

我很确定这是一个Thin问题，而不是nginx问题，因此我要发布更新.抱歉造成任何混乱.

I am pretty sure this is a Thin issue and not an nginx issue so I am posting an update. Sorry for any confusion.

我的网站运行了大约10秒钟，然后出现502 nginx错误.我的nginx配置似乎很好，并且nginx -t成功.我的错误信息是这样的:

my website is up for about 10 seconds and then I get the 502 nginx error. My nginx config seems fine and the nginx -t is successful. My error message is this:
