Question

我运行时已启用/可用已配置的nginx网站：

nginx -t

我得到了一个成功的测试，当我：

service nginx restart
thin restart -s 1

我的502错误消失但只持续了十秒钟，然后再次出现。我的网站可用：

upstream myapp {
server 0.0.0.0:3000;

}

服务器{ 听80默认;

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;
    }
}

}

有谁知道为什么我的配置只能工作几秒钟？感谢您的帮助，如果您需要查看我的其他任何代码，请告诉我。

thin restart -s 2输出：

我很确定这是一个瘦问题而不是nginx问题所以我发布了一个更新。抱歉有任何困惑。

我的网站启动了大约10秒，然后我得到502 nginx错误。我的nginx配置似乎很好，nginx -t成功。我的错误信息是：

thin restart -s 5

我检查过PID，他们在那里。有没有人知道这里发生了什么？谢谢你，我感谢任何建议。

我找到了运行清理那些细小错误所需要的东西。我不知道为什么，但跑步：

bundle exec thin start -p 3000

修复了我的情况。谢谢大家的帮助！没有你，我无法找到它。
