更改Node.js监听端口 [英] Changing Node.js listening port

问题描述

我刚刚在Windows上安装了node.js.我有一个无法运行的简单代码:

I just installed node.js on Windows. I have this simple code which does not run:

我得到: 错误:听EADDRINUSE

I get: Error: listen EADDRINUSE

是否有一个配置文件告诉node.js在特定端口上进行侦听?

Is there a config file that tells node.js to listen on a specific port?

问题是我已经让Apache监听了端口80.

The problem is I have Apache listening on port 80 already.

var http = require('http'); 
var url = require('url'); 

http.createServer(function (req, res) { 
 console.log("Request: " + req.method + " to " + req.url); 
 res.writeHead(200, "OK"); 
 res.write("<h1>Hello</h1>Node.js is working"); 
 res.end(); 
}).listen(5454); 
console.log("Ready on port 5454");

推荐答案

除非您

There is no config file unless you create one yourself. However, the port is a parameter of the listen() function. For example, to listen on port 8124:

var http = require('http');
http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Hello World\n');
}).listen(8124, "127.0.0.1");
console.log('Server running at http://127.0.0.1:8124/');

如果在查找打开的端口时遇到问题，可以转到命令行并输入:

If you're having problems finding a port that's open, you can go to the command line and type:

netstat -ano

要查看每个适配器正在使用的所有端口的列表.
