Question

我已经在端口4210上运行的nginx上部署了我的项目（角度）。我正在使用aws ec2实例。当我尝试在浏览器上运行项目时，它给我500个内部服务器错误。您能告诉我这是我哪里错了。这是我的第一次。

nginx -t取得了成功，Angular服务器也在工作

----默认服务器配置（站点可用）----

```server {
        listen 80;
        listen [::]:80;
        listen 127.0.0.1;
        proxy_connect_timeout       600s;
        proxy_send_timeout          600s;

        index index.html index.htm index.nginx-debian.html;

        server_name _;

        location / {

   }```
my nginx.conf file ------------

  ```user www-data;

     include /etc/nginx/modules-enabled/*.conf;

Answer 1

以下是一些解决方案：

安装dnsmasq：sudo apt-get install dnsmasq，以使本地DNS服务器在127.0.0.1上运行（类似于[1]）
更新nginx配置并将resolver 169.254.169.253设置为对VPC [2]中的EC2实例使用默认的AWS DNS服务器

这是有关dnsmasq [3]的AWS知识中心的链接

NGINX配置解析器不适用于本地主机
