Nginx 反向代理端口 3001

Question

我有一個在端口 3001 上運行的快速服務器，它為 React 應用程序提供服務。

假設我的域名是 example.com； 我想要實現的是：

1. 可以調用https://example.net/api/getUsers

2. 從http://1.2.3.4:3001/重定向到https://example.net/

3. 基本上將所有 HTTP 調用（無論是作為 IP 還是域）重定向到https://example.net/

任何人都可以幫助設置 Nginx 配置嗎？ 這是我目前在 /etc/nginx/sites-available 下的內容：

server {
        server_name 1.2.3.4:3001;
        return 301 https://example.net;
}

server {
        listen 80 default_server;
        listen [::]:80 default_server;
        listen 443 default_server ssl;
        listen [::]:443 default_server ssl;
        server_name example.net www.example.net;

        return 301 https://example.net$request_uri;
}

server {
  listen 80;

  server_name example.net www.example.net;

  location / {
    proxy_pass http://localhost:3001;
    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;
  }

    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/example.net/fullchain.pem; # managed by Certbot
   ssl_certificate_key /etc/letsencrypt/live/example.net/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

}

看起來您的應用正在返回重定向位置： http://1.2.3.4:3001/您可以使用 proxy_redirect 重寫它並減少冗余內容。

 server { listen 80 default_server; return 301 https://example.net$request_uri; } server { listen 443 ssl; # managed by Certbot ssl_certificate /etc/letsencrypt/live/example.net/fullchain.pem; # managed by Certbot ssl_certificate_key /etc/letsencrypt/live/example.net/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_name example.net www.example.net; location / { proxy_pass http://localhost:3001; 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; proxy_redirect http://1.2.3.4:3001/ $scheme://$host/; } }

是的，您可以添加以下重定向：

server {
        listen 1.2.3.4:3001;
        return 301 https://example.net;
}

但請注意您的反應應用程序。 本地監聽 localhost:3001

proxy_pass http://localhost:3001;

所以確保反應應用程序。 也沒有在 1.2.3.4:3001 套接字上監聽。 否則，您將收到Address already in use錯誤，nginx 將無法啟動。
