Question

我将nginx配置为端口80和443上的反向代理，并让Certbot自动管理SSL证书。

我拥有的Golang Web应用程序在端口8000上运行。任何人都可以通过非https IP地址访问具有端口:8000的Web服务器的Web应用程序。

除了仅阻止到:8000的所有流量外，禁用端口的正确方法是什么，以便Web服务器仅向80和443的流量提供服务？

好，我的Go应用仅服务127.0.0.1:8000而不是:8000，现在导航到服务器的IP地址时，找不到404页。我根本不需要服务器的IP地址。如何在Nginx中进行配置？

此外，nginx文档还使用@proxy：https://www.nginx.com/resources/wiki/start/topics/tutorials/config_pitfalls/#proxy-everything来“代理一切”（在此处阅读有关内容）。我的配置是正确的方法吗？

这是我的/etc/nginx/nginx.conf的Nginx配置：

user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;

# Load dynamic modules. See /usr/share/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;

events {
    worker_connections 20000;
}

http {

    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;
    tcp_nodelay         on;
    keepalive_timeout   65;
    types_hash_max_size 2048;

    include             /etc/nginx/mime.types;
    default_type        application/json;

    # Load modular configuration files from the /etc/nginx/conf.d directory.
    # See http://nginx.org/en/docs/ngx_core_module.html#include
    # for more information.
    include /etc/nginx/conf.d/*.conf;

    # Include server blocks.
    include /etc/nginx/sites-enabled/*.conf;
}

这是/etc/nginx/sites-enabled/default_server.conf的nginx配置：

upstream default_server {
    server 127.0.0.1:8001;
    keepalive 12;
}

server {
    server_tokens off;
    server_name api.example.com;

    client_body_buffer_size     32k;
    client_header_buffer_size   8k;
    large_client_header_buffers 8 64k;
    location / {
        proxy_pass http://127.0.0.1:8001;
   }

   location @proxy {
        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;
   }

    listen [::]:443 ssl ipv6only=on; # managed by Certbot
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/api.example.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/api.example.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 ($host = api.example.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


    listen 80 default_server;
    listen [::]:80 default_server;
    server_name api.example.com;
    return 404; # managed by Certbot


}

您可以对您的应用程序进行编码，以使其不会仅回答每个地址。相反，它只需要回答本地主机的请求即可。

例如：

    log.Fatal(http.ListenAndServe("127.0.0.1:8000", router))

在端口8000和443上将nginx配置为反向代理，以便在8000上运行的webapp。如何禁用与端口8000的连接？
