aws弹性beanstalk nginx反向代理设置

Question

我跟着这两个帖子，但没有运气

https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/java-se-nginx.html

https://davidojeda.mx/blog/2018/01/11/extend-nginx-config-on-aws-elasticbeanstalk

我刚刚开始在手边玩elastic beanstalk。

顺其自然，我用port:8000启动服务器我想做一个反向代理，所以它会收听端口80。

我没有用elb开始做这个，因为我想在进入elb之前更多地了解基础知识

这是我运行应用程序的index.js

const express = require('express');
const app = express();
const port = 8000;

app.get('/', async (req, res) => {
    return res.json({ status: true });
});

app.listen(port, () => console.log(`Example app listening on port ${port}!`));

以上将确保如果网址是http://eb_self_generated_url:8000所以我想让它与https://eb_self_generated_url一起使用

我正在阅读一些帖子，但它们都没有用。

在我的根，我创造了.ebextensions/nginx/conf.d/s_proxy.conf和我内心

upstream nodejs {
    server 127.0.0.1:8081;
    keepalive 256;
}

server {
    listen 8080;

    if ($time_iso8601 ~ "^(\d{4})-(\d{2})-(\d{2})T(\d{2})") {
        set $year $1;
        set $month $2;
        set $day $3;
        set $hour $4;
    }

    access_log /var/log/nginx/healthd/application.log.$year-$month-$day-$hour healthd;
    access_log  /var/log/nginx/access.log  main;

    location / {
        # this is actually what need to be changed
        # I tried changing from http://nodejs to http://localhost:8000 at server which then will make the reverse proxy work
        proxy_pass  http://localhost:8000;
        proxy_set_header   Connection "";
        proxy_http_version 1.1;
        proxy_set_header        Host            $host;
        proxy_set_header        X-Real-IP   $remote_addr;
        proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
    }

    gzip on;
    gzip_comp_level 4;
    gzip_types text/plain text/css application/json application/javascript application/x-javascript text/xml appl$
}

我试图拉上面和update / deploy，但没有任何变化

我也尝试在我的应用程序.ebextensions/proxy.conf下创建它

files：/etc/nginx/conf.d/：owner：root group：root content：|上游nodejs {server 127.0.0.1:8081; keepalive 256; }

  server {
      listen 8080;

      if ($time_iso8601 ~ "^(\d{4})-(\d{2})-(\d{2})T(\d{2})") {
          set $year $1;
          set $month $2;
          set $day $3;
          set $hour $4;
      }

      access_log /var/log/nginx/healthd/application.log.$year-$month-$day-$hour healthd;
      access_log  /var/log/nginx/access.log  main;

      location / {
          proxy_pass  http://localhost:8000;
          proxy_set_header   Connection "";
          proxy_http_version 1.1;
          proxy_set_header        Host            $host;
          proxy_set_header        X-Real-IP $remote_addr;
          proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
      }

      gzip on;
      gzip_comp_level 4;
      gzip_types text/plain text/css application/json application/javascript application/x-javascript text/xml appl$

      # Include the Elastic Beanstalk generated locations
      include conf.d/elasticbeanstalk/01_static.conf;
      include conf.d/elasticbeanstalk/healthd.conf;
  }

仍然没有让反向代理工作的运气。

有人能帮我一把吗？

感谢您的任何帮助和建议。

您是否注意到您在nginx配置中使用端口8081而不是您的应用程序端口（8000）？

upstream nodejs {
    server 127.0.0.1:8081;
    keepalive 256;
}
