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');
});
