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)

config.php

<?php
return [
    //配置
    "host" => [
        "host" => "127.0.0.1",
        "port" => "5672",
        "login" => "guest",
        "password" => "guest",
        "vhost"=>"/",
    ],
    //交换机
    "exchange"=>"word",
    //路由
    "routes" => [],
];

以上内容希望帮助到大家，很多PHPer在进阶的时候总会遇到一些问题和瓶颈，业务代码写多了没有方向感，不知道该从那里入手去提升，对此我整理了一些资料，包括但不限于：分布式架构、高可扩展、高性能、高并发、服务器性能调优、TP6，laravel，YII2，Redis，Swoole、Swoft、Kafka、Mysql优化、shell脚本、Docker、微服务、Nginx等多个知识点高级进阶干货需要的可以免费分享给大家，需要戳这里 PHP进阶架构师>>>视频、面试文档免费获取
