这是我的节点文件

我在/上有HTML

和/app上的节点应用程序

server {
    listen 80;
    listen 443 ssl;
    listen [::]:443 ssl;
    server_name localhost;

    ssl_certificate "/etc/letsencrypt/live/xxxxx/fullchain.pem";
    ssl_certificate_key "/etc/letsencrypt/live/xxxxxxx/privkey.pem";

    ssl_session_cache shared:SSL:1m;
    ssl_session_timeout  10m;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers HIGH:SEED:!aNULL:!eNULL:!EXPORT:!DES:!RC4:!MD5:!PSK:!RSAPSK:!aD$
    ssl_prefer_server_ciphers on;


        location / {
        # This would be the directory where your frontend code resides
        root /usr/share/nginx/html;
        index index.html;
        try_files $uri $uri/ =404;
        }

        location /api {
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-NginX-Proxy true;
        proxy_pass http://127.0.0.1:3000;
        proxy_set_header Host $http_host;
        proxy_redirect off;
        }
}

server {
    listen 80;
    listen [::]:80;
    server_name localhost;
    return 302 https://xxxxx.com;
}

我也转发了3000端口到80；

我想在这个服务器上的一个不同的端口上运行多个应用程序。

我应该为其他应用程序配置什么。
