node.js - AWS elastic beanstalk 上的默认代理配置将请求转发到的 Web 应用程序的端口号是多少？

Question

困惑发生在 this pag e 在“反向代理配置”下已经提到了:

By default, Elastic Beanstalk configures the proxy to forward requests coming in on port 80 to your main web application on port 5000.

然后 this page它是这样提到的:

By default, Elastic Beanstalk configures the proxy to forward requests to your application on port 8080.

那么请求转发到的默认端口是 5000 端口还是 8080 端口？

Answer 1

在 Amazon Linux 2 上是 8080。您可以通过检查 EB 实例上的默认 nginx 设置来检查它:

cat /etc/nginx/conf.d/elasticbeanstalk/00_application.conf 

location / {
    proxy_pass          http://127.0.0.1:8080;
    proxy_http_version  1.1;

    proxy_set_header    Connection          $connection_upgrade;
    proxy_set_header    Upgrade             $http_upgrade;
    proxy_set_header    Host                $host;
    proxy_set_header    X-Real-IP           $remote_addr;
    proxy_set_header    X-Forwarded-For     $proxy_add_x_forwarded_for;
}

5000 可能来自 Amazon Linux 1，不确定。
