Question

我一直在努力与一整天一起部署Angular 7应用程序以及node，express和mongo，我感到很困惑。有些关于如何在整个互联网中做到这一点的解释并不充分。请帮忙！

我在DigitalOcean上。我已经设置了Nginx，并且可以在我的IP地址上看到Nginx索引页面。我还设置了一个服务器块，其中有两个位置，一个用于我实际的Angular应用程序，另一个用于我的express api。这是代码：

server {

        root /var/www/devgrub.com/html;
        index index.html index.htm index.nginx-debian.html;

        server_name devgrub.com www.devgrub.com;

        location / {
                try_files $uri $uri/ =404;
        }

        location /api {
                proxy_pass http://localhost:8080;
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection 'upgrade';
                proxy_set_header Host $host;
                proxy_cache_bypass $http_upgrade;
                #try_files $uri $uri/ =404;
        }

    listen [::]:443 ssl ipv6only=on; # managed by Certbot
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/devgrub.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/devgrub.com/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot


}
server {
    if ($host = www.devgrub.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


    if ($host = devgrub.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


        listen 80;
        listen [::]:80;

        server_name devgrub.com www.devgrub.com;
    return 404; # managed by Certbot

}

在/var/www/devgrub.com/html内部，我已上传了运行ng build --prod后生成的Angular应用程序的代码

在/home/devgrub内部，我有我的express / node应用程序。

我可以在devgrub.com上成功进入我的Angular应用程序，但是当我去devgrub.com/api时，给我的是hello world，它是我在遵循以下设置教程时制作的原始节点应用程序DigitalOcean。我重新启动了运行PM2的节点应用，现在访问devgrub.com/api时它显示为502 Bad Gateway。

我在Angular应用中更改了所有localhost api调用，希望这样做可以但不会。我已经用use devgrub创建了数据库，但是Angular应用似乎无法连接到它，并且由于我对此还很陌生，所以我知道从哪里开始进行故障排除。请帮忙！

更新这是Nginx错误日志中的一些错误

您好，您好吗，请您分享您的服务器utf防火墙设置，以防万一如果防火墙中不允许使用IP，您可能会遇到这些问题。
