1. 安装RabbitMQ

拉取镜像

docker pull rabbitmq:3.7.7-management

docker run -d --name rabbitmq3.7.7 -p 5672:5672 -p 15672:15672 -v `pwd`/data:/var/lib/rabbitmq --hostname myRabbit -e RABBITMQ_DEFAULT_VHOST=my_vhost  -e RABBITMQ_DEFAULT_USER=admin -e RABBITMQ_DEFAULT_PASS=admin df80af9ca0c9

http://ip:15672

2. composer安装php-amqplib

composer require php-amqplib/php-amqplib

3.Tp5 实现

再次封装php-amqplib
