thinkphp5.0使用RabbitMq

本次操作是以docker为基础进行操作

1.在docker上pull rabbitmq

docker pull rabbitmq:management

docker run -d --hostname rabbit-host --restart always --name rabbitmq -e RABBITMQ_DEFAULT_USER=admin -e RABBITMQ_DEFAULT_PASS=123456 -p 15672:15672 -p 5672:5672 rabbitmq:3.8.9-management-alpine

 Thinkphp5.0引入RabbitMq

{
    "require": {
        "php-amqplib/php-amqplib": ">=2.6.1"
    }
}

 在命令行执行

composer install

或者 直接运行包引入

composer require php-amqplib/php-amqplib

use PhpAmqpLibConnectionAMQPStreamConnection;
use PhpAmqpLibMessageAMQPMessage;
use thinkLog;

    protected $queue = 'msgs';// 的队列名
    protected $connection; //amqp 链接
    protected $channel;//开启通道

    public function __construct(){
        // 连接rabbitMQ
        $connection = new AMQPStreamConnection('127.0.0.1', 5672, 'user', '123456', '/');

        $channel = $connection->channel();

        // queue 队列名
        // passive 检测队列是否存在  true 只检测不创建 false 创建
