我在安装了Node.js的Amazon EC2上运行Debian实例.如果我运行以下代码:

http = require('http');

http.createServer(function (request, response){
  response.writeHead(200, {'Content-Type':'text/plain'});
  response.end('Hello World\n');
}).listen(80);
console.log("Running server at port 80");

我得到下面的输出告诉我有另一个进程在端口80监听:

Running server at port 80

events.js:72
        throw er; // Unhandled 'error' event
              ^
Error: listen EACCES
    at errnoException (net.js:901:11)
    at Server._listen2 (net.js:1020:19)
    at listen (net.js:1061:10)
    at Server.listen (net.js:1127:5)
    at Object.<anonymous> (/home/admin/nodetests/nodetest.js:6:4)
    at Module._compile (module.js:456:26)
    at Object.Module._extensions..js (module.js:474:10)
    at Module.load (module.js:356:32)
    at Function.Module._load (module.js:312:12)
    at Function.Module.runMain (module.js:497:10)

现在,当我检查是否有一个进程(以root用户隐藏)时,使用以下方法监听端口80:

netstat -tupln

我得到以下输出,它告诉我没有在端口80收听:

Active Internet connections (only servers)
