实际中会用pm2来处理，这里只是了解下原理和网络模块

纠正：net.createServerHandle();
记录：http://www.jianshu.com/p/54b85f278695
代码：
master
const net = require(‘net‘);
const fork = require(‘child_process‘).fork;
var handle = net.createServerHandle(‘0.0.0.0‘, 3000);
for(var i=0;i<4;i++) {
fork(‘./worker‘).send({}, handle);
}
worker
const net = require(‘net‘);
process.on(‘message‘, function(m, handle) {
start(handle);
});
var buf = ‘hello nodejs‘;
var res = [‘HTTP/1.1 200 OK‘,‘content-length:‘+buf.length].join(‘\r\n‘)+‘\r\n\r\n‘+buf;
function start(server) {
server.listen();
server.onconnection = function(err,handle) {
console.log(‘got a connection on worker, pid = %d‘, process.pid);
var socket = new net.Socket({
handle: handle
});
socket.readable = socket.writable = true;
socket.end(res);
}
}
解释，fork(‘/worker)->emit(‘message‘)
