什么是MQ?
MQ全称为Message Queue, 消息队列(MQ)是一种应用程序对应用程序的通信方法。MQ是消费-生产者模型的一个典型的代表,一端往消息队列中不断写入消息,而另一端则可以读取队列中的消息。
RabbitMQ就是MQ的一种,本文介绍了使用PHP访问RabbitMQ消息队列的方法,结合实例形式分析了RabbitMQ消息队列的相关扩展安装、队列建立、队列绑定、消息发送、消息接收等相关操作技巧,需要的朋友可以参考下
扩展安装
PHP访问RabbitMQ实际使用的是AMQP协议,所以我们只要安装epel库中的php-pecl-amqp这个包即可
rpm -ivh http://mirror.neu.edu.cn/fedora/epel/6/x86_64/epel-release-6-8.noarch.rpm
yum install php-pecl-amqp
交换建立
<?php
$connection = new AMQPConnection();
$connection->connect();
$channel = new AMQPChannel($connection);
$exchange = new AMQPExchange($channel);
$exchange->setName('exchange1');
$exchange->setType('fanout');
$exchange->declare();
队列建立
<?php
$connection = new AMQPConnection();
$connection->connect();
$channel = new AMQPChannel($connection);
$queue = new AMQPQueue($channel);
$queue->setName('queue1');
$queue->declare();
队列绑定
<?php
$connection = new AMQPConnection();
$connection->connect();
$channel = new AMQPChannel($connection);
$queue = new AMQPQueue($channel);
$queue->setName('queue1');
$queue->declare();
$queue->bind('exchange1', 'routekey');
消息发送
<?php
$connection = new AMQPConnection();
$connection->connect();
$channel = new AMQPChannel($connection);
$exchange = new AMQPExchange($channel);
$exchange->setName('exchange5');
$exchange->setType('fanout');
$exchange->declare();
for($i = 0; $i < 2000000; $i++) {
$exchange->publish("message $i", "routekey");
}
消息接收
<?php
$connection = new AMQPConnection();
$connection->connect();
$channel = new AMQPChannel($connection);
$queue = new AMQPQueue($channel);
$queue->setName('queue1');
$queue->declare();
$queue->bind('exchange1', 'routekey');
while (true) {
$queue->consume(function($envelope, $queue){
echo $envelope->getBody(), PHP_EOL;
}, AMQP_AUTOACK);
}
看完是不是觉得很简单,这个做消息队列不难!
