NGINX 反向代理上游未連接到特定連接埠

NGINX 反向代理上游未連接到特定連接埠

我試圖訪問其中一台後端伺服器，但收到此錯誤：

27#27: *21653 connect() 失敗（111：連線被拒絕），同時連線到上游，客戶端：84.255.55.25，伺服器：premium.maltacraft.net，要求：“GET / HTTP/1.1”，上游： “http: //172.28.0.3:37200/”，主機：“premium.maltacraft.net”

我有一個 docker-compose 堆疊，如下所示（為了簡單起見，編輯了一些服務）：

services:
  nginx-ingress:
    image: nginx:latest
    logging:
      driver: "json-file"
      options:
        max-size: "50m"
        max-file: "10"
    restart: unless-stopped
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - "./nginx-ingress/nginx.conf:/etc/nginx/nginx.conf:ro"
      - "./nginx-ingress/dhparam.pem:/etc/ssl/dhparam.pem:ro"
      - "./nginx-ingress/sites-available:/etc/nginx/sites-available:ro"
      - "./nginx-ingress/sites-enabled:/etc/nginx/sites-enabled:ro"
      - "./nginx-ingress/webroot:/var/www"
      - "/etc/letsencrypt:/etc/letsencrypt:ro"
    networks:
      - multicraft
      - wp_maltacraft

networks:
  multicraft:
  wp_maltacraft:

這是我的 nginx.conf 檔案（非常基本）：

user  nginx;
worker_processes  auto;

error_log  /var/log/nginx/error.log notice;
pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

    include /etc/nginx/sites-enabled/*.conf;
}

現在，我有 2 個網站連接到 Apache 伺服器，分別稱為 Vanilla 和 Premium。 Vanilla 可以工作，你可以在這裡看到它的工作： https://vanilla.maltacraft.net/

但高級版則不然，如下圖所示： https://premium.maltacraft.net/

vanilla.maltacraft.net.conf：


upstream vanilla {
    server multicraft:38200;
}

server {
    listen 443 ssl;
    listen [::]:443 ssl;
    server_name vanilla.maltacraft.net;
    server_tokens off;
    ssl_certificate /etc/letsencrypt/live/vanilla.maltacraft.net/fullchain.pem;

    ssl_protocols TLSv1.2 TLSv1.3;
    ssl_prefer_server_ciphers on;
    ssl_session_cache  builtin:1000  shared:SSL:10m;
    ssl_session_timeout  5m;
    add_header Strict-Transport-Security "max-age=63072000";
    add_header 'X-Frame-Options' 'SAMEORIGIN';
    add_header 'X-XSS-Protection' '1; mode=block';
    add_header 'X-Content-Type-Options' 'nosniff';
    add_header 'Referrer-Policy' 'no-referrer';
    ssl_dhparam /etc/ssl/dhparam.pem;

    location / {
        proxy_read_timeout 3600;
        proxy_pass http://vanilla;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Forwarded-Ssl on;
    }
}

premium.maltacraft.net.conf：


upstream premium {
    server multicraft:37200;
}

server {
    listen 443 ssl;
    listen [::]:443 ssl;
    server_name premium.maltacraft.net;
    server_tokens off;
    ssl_certificate /etc/letsencrypt/live/premium.maltacraft.net/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/premium.maltacraft.net/privkey.pem;

    ssl_ciphers ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POL>

    ssl_protocols TLSv1.2 TLSv1.3;
    ssl_prefer_server_ciphers on;
    ssl_session_cache  builtin:1000  shared:SSL:10m;
    ssl_session_timeout  5m;
    add_header Strict-Transport-Security "max-age=63072000";
    add_header 'X-Frame-Options' 'SAMEORIGIN';
    add_header 'X-XSS-Protection' '1; mode=block';
    add_header 'X-Content-Type-Options' 'nosniff';
    add_header 'Referrer-Policy' 'no-referrer';
    ssl_dhparam /etc/ssl/dhparam.pem;

    location / {
        proxy_read_timeout 3600;
        proxy_pass http://premium;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Forwarded-Ssl on;
    }
}

如果我將高級版 (37200) 的上游連接埠更改為香草版 (38200)，它會正常工作，並且會向我顯示香草版的網站。但我希望它顯示高級網站。

這兩個網站都已生成並運行其 SSL 證書，並且已為它們生成了符號連結（因為它們在sites-enabled資料夾中都具有相同的配置）

知道可以採取什麼措施來解決這個問題嗎？或者也許要調試

答案1

問題是後端伺服器試圖監聽 localhost (127.0.0.1) 而不是 0.0.0.0。更改了它，現在可以使用了
