香蕉派安装node.js

http://cnodejs.org/topic/54032efa9769c2e93797cd06

wget http://nodejs.org/dist/v0.10.26/node-v0.10.26-linux-arm-pi.tar.gz tar -xvzf node-v0.10.26-linux-arm-pi.tar.gz
node-v0.10.26-linux-arm-pi/bin/node --version

接下来写进我们的环境变量

vi .bash_profile

在里面写入

PATH=$PATH:/home/pi/node-v0.10.26-linux-arm-pi/bin

在运行source 更新

source .bash_profile

现在我们有Node命令了

node --version

1、git clone git://github.com/joyent/node.git

2、cd node

3、./configure

4、./make && make install

5、npm install --save express@4.10.2

6、npm install --save socket.io

index.js
var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io')(http);
app.get('/', function(req, res){
  //res.send('<h1>Hello world</h1>');
  res.sendFile(__dirname + '/index.html');
});
//io.on('connection', function(socket){
//	  console.log('a user connected');
//	  socket.on('disconnect', function(){
//		      console.log('user disconnected');
//		        
//	  });
//});
//io.on('connection', function(socket){
//	socket.on('chat message', function(msg){
//		    console.log('message: ' + msg);
//	});
//});
io.on('connection', function(socket){
 socket.on('chat message', function(msg){
    io.emit('chat message', msg);
 });
});

http.listen(3000, function(){
  console.log('listening on *:3000');

});
