node.js - Nginx 反向代理不适用于域名

Question

我已经在 SO 上尝试了所有的解决方案，但没有成功。我想使用 Nginx 作为“Node.js”应用程序反向代理。使用我当前的配置，我能够在通过服务器 IP 连接到它时使它工作，但在使用其域名时不能。我的配置详细信息 pastebin.com/gMqpmDwj

http://Ipaddress:3000 有效，但 http://example.com 无效。

这是我的 Nginx 代理的配置，存储在 /etc/Nginx/conf.d/domain.conf 中。

server {
    listen 80;
    server_name domain_name;

    location / {
        proxy_set_header   X-Forwarded-For $remote_addr;
        proxy_set_header   Host $http_host;
        proxy_pass         http://ipaddress:3000;
    }
}

但是当我尝试访问它时，它在 ip:port 上工作正常，但在 domain:port 上或没有 port 时它不

试试这个配置:

/etc/nginx/nginx.conf

user                nobody;
worker_processes    1;
pid                 /var/run/nginx.pid;

events {
    worker_connections  1024;
    multi_accept on;
}

http {
    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    keepalive_timeout 15;
    types_hash_max_size 2048;
    client_max_body_size 8M;
    server_tokens off;

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

    access_log off;
    error_log /var/log/nginx/error.log crit;

    gzip on;
    gzip_min_length 100;
    gzip_http_version 1.1;
    gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;

    include /etc/nginx/cloudflare.inc;
    include /etc/nginx/conf.d/*.conf;
}

/etc/nginx/conf.d/domain.conf

upstream nodejs_app {
    server <ipaddress>:3000;
    keepalive 8;
}

server {
    listen 80;
    listen [::]:80;
    server_name <domain_name>;

    location / {
        # websocket support
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";

        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_set_header X-NginX-Proxy true;

        proxy_pass http://nodejs_app/;
        proxy_redirect off;
    }
}
