Forwarding port 80 to 8080 using NGINX
提问by heron
I'm using LEMP stack and Node JS on my debian server. Nginx works on port 80 and Node JS on 8080. I created new subdomain: cdn.domain.com for nodejs app. Currently I can access to Node JS application only like cdn.domain.com:8080/. What I want to do is to configure Nginx so that, when I enter to cdn.domain.com I can get app working on port 80. I think it can be done using nginx upstream. But I can't figure out how.
我在我的 debian 服务器上使用 LEMP 堆栈和 Node JS。Nginx 在 80 端口和 8080 上的 Node JS 上工作。我为 nodejs 应用程序创建了新的子域：cdn.domain.com。目前我只能像 cdn.domain.com:8080/ 一样访问 Node JS 应用程序。我想要做的是配置 Nginx，以便当我进入 cdn.domain.com 时，我可以让应用程序在端口 80 上工作。我认为可以使用上游 nginx 来完成。但我无法弄清楚如何。

As simple as like this,
就这么简单，
make sure to change example.com to your domain (or IP), and 8080 to your Node.js application port:
确保将 example.com 更改为您的域（或 IP），并将 8080 更改为您的 Node.js 应用程序端口：
server {
listen 80;
server_name example.com;
location / {
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header Host $http_host;
proxy_pass "http://127.0.0.1:8080";
}
}

NGINX supports WebSockets by allowing a tunnel to be setup between a client and a backend server. In order for NGINX to send the Upgrade request from the client to the backend server, Upgrade and Connection headers must be set explicitly. For example:
NGINX 通过允许在客户端和后端服务器之间建立隧道来支持 WebSockets。为了让 NGINX 将升级请求从客户端发送到后端服务器，必须明确设置升级和连接标头。例如：
# WebSocket proxying
map $http_upgrade $connection_upgrade {
default upgrade;
'' close;
}
server {
listen 80;
# The host name to respond to
server_name cdn.domain.com;
location / {
# Backend nodejs server
proxy_pass http://127.0.0.1:8080;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $connection_upgrade;
}
}

This is how you can achieve this.
这就是您可以实现这一目标的方法。
upstream {
nodeapp 127.0.0.1:8080;
}
server {
listen 80;
# The host name to respond to
server_name cdn.domain.com;
location /(.*) {
proxy_pass http://nodeapp/$is_args$args;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header Host $host;
proxy_set_header X-Real-Port $server_port;
proxy_set_header X-Real-Scheme $scheme;
}
}
You can also use this configuration to load balance amongst multiple Node processes like so:
您还可以使用此配置在多个 Node 进程之间进行负载平衡，如下所示：
upstream {
nodeapp 127.0.0.1:8081;
nodeapp 127.0.0.1:8082;
nodeapp 127.0.0.1:8083;
}
Where you are running your node server on ports 8081, 8082 and 8083 in separate processes. Nginx will easily load balance your traffic amongst these server processes.
您在不同进程中的端口 8081、8082 和 8083 上运行节点服务器的位置。Nginx 将轻松地在这些服务器进程之间平衡您的流量。

Simple is:
简单的是：
server {

server_name p3000;
location / {
proxy_pass http://0.0.0.0:3000;
include /etc/nginx/proxy_params;
}

You can define an upstream and use it in proxy_pass
您可以定义一个上游并在 proxy_pass 中使用它

回答by SHIVAPUTRA UDAGATTI
you can do this very easy by using following in sudo vi /etc/nginx/sites-available/default
您可以通过使用以下内容轻松做到这一点 sudo vi /etc/nginx/sites-available/default
server {
listen 80 default_server;
listen [::]:80 default_server;
server_name _ your_domain;
location /health {
access_log off;
return 200 "healthy\n";
}
location / {
proxy_pass http://localhost:8080;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_cache_bypass $http_upgrade;
}
}
回答by Vishrant
This worked for me:
这对我有用：
server {
listen 80;
server_name example.com www.example.com;
location / {
proxy_pass http://127.0.0.1:8080/;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
If it does not work for you look at the logs at sudo tail -f /var/log/nginx/error.log
如果它对您不起作用，请查看日志 sudo tail -f /var/log/nginx/error.log
