为了适应公司产品要求语言无关性的详细传递需求，今天对RabbitMQ进行了初步了解。

首先来看下RabbitMQ在 fedora12 下面的安装过程，因为RabbitMQ是用Erlang写的，所有需要安装Erlang的语言环境。
官方给出的EPEL(Extra Packages for Enterprise Linux )，在fedora的添加/删除程序中搜索 Erlang，勾上Runtime Environment即系统会进行package依赖检查，等待下载安装......
EPEL详见：http://fedoraproject.org/wiki/EPEL
安装RabbitMQ Server
下载RPM安装包：http://www.rabbitmq.com/server.html
rpm -ivh XXXXX.rpm
其实RabbitMQ Server还有许多配置选项，我们这里就不配置了
运行RabbitMQ Server
/sbin/service rabbitmq-server start，如果需要把进程变成守护进程，运行：chkconfig rabbitmq-server on，rabbitmq的默认端口是：5672
检测server是否已经启动 ps -ef|grep rabbmit
官方的安装说明：http://www.rabbitmq.com/install.html#rpm
HelloWorld
发送端
package com.vixtel;import java.io.IOException;import com.rabbitmq.client.Channel;import com.rabbitmq.client.Connection;import com.rabbitmq.client.ConnectionFactory;public class Send {/** * @param args */public static void main(String[] args) {try {String queueName = "hello";Connection conn = new ConnectionFactory().newConnection();Channel channel = conn.createChannel();channel.queueDeclare(queueName, false, false, false, null);channel.basicPublish("", queueName, null, "Hello World".getBytes());} catch (IOException e) {e.printStackTrace();}}}
接收端
package com.vixtel;import java.io.IOException;import com.rabbitmq.client.Channel;import com.rabbitmq.client.Connection;import com.rabbitmq.client.ConnectionFactory;import com.rabbitmq.client.QueueingConsumer;import com.rabbitmq.client.ShutdownSignalException;public class Receive {/** * @param args */public static void main(String[] args) {// TODO Auto-generated method stubtry {String queueName = "hello";Connection conn = new ConnectionFactory().newConnection();Channel channel = conn.createChannel();channel.queueDeclare(queueName, false, false, false, null);QueueingConsumer consumer = new QueueingConsumer(channel);channel.basicConsume(queueName, true, consumer);while(true) {try {QueueingConsumer.Delivery delivery = consumer.nextDelivery();System.out.println(new String(delivery.getBody()));} catch (ShutdownSignalException e) {e.printStackTrace();} catch (InterruptedException e) {e.printStackTrace();}}} catch (IOException e) {e.printStackTrace();}}}
