前言
为什么使用RabbitMq而不是ActiveMq或者RocketMq？
首先，从业务上来讲，我并不要求消息的100%接受率，并且，我需要结合php开发，RabbitMq相较RocketMq，延迟较低(微妙级)。至于ActiveMq，貌似问题较多。RabbitMq对各种语言的支持较好，所以选择RabbitMq。
先安装PHP对应的RabbitMQ,这里用的是 php_amqp 不同的扩展实现方式会有细微的差异.
php扩展地址: http://pecl.php.net/package/amqp
具体以官网为准 http://www.rabbitmq.com/getstarted.html
介绍
- config.php 配置信息
- BaseMQ.php MQ基类
- ProductMQ.php 生产者类
- ConsumerMQ.php 消费者类
- Consumer2MQ.php 消费者2(可有多个)
