docker安装RabbitMQ和延时插件

RabbitMQ是实现了高级消息队列协议（AMQP）的开源消息代理软件（亦称面向消息的中间件）

使用 docker安装 RabbitMQ和延时插件，实现消息延时消费

1、docker 安装 RabbitMQ

docker拉取镜像

docker pull rabbitmq:3.10-management

开启容器

docker run -it --name rabbitmq -p 5672:5672 -p 15672:15672 -d rabbitmq:3.10-management

开启容器后，浏览器访问宿主机器 ip+15672端口，访问RabbitMQ管理页面

笔者的宿主机器 ip 是 192.168.5.25

初始账号密码都是guest

2、安装延时插件

下载插件地址：https://www.rabbitmq.com/community-plugins.html

找到 rabbitmq_delayed_message_exchange

点击进入下载页面

找到对应的版本进行下载

下载插件后，将插件上传到服务器

使用 docker 命令将插件复制到容器内部 plugins目录下

docker cp rabbitmq_delayed_message_exchange-3.10.0.ez  rabbitmq:/plugins

进入容器内部进行查看

docker exec -it rabbitmq bash

进入 plugins 目录查看

cd plugins

执行命令安装插件

rabbitmq-plugins enable rabbitmq_delayed_message_exchange

通过命令查看已安装的插件

rabbitmq-plugins list

退出容器后，重启 rabbitmq 容器

docker restart rabbitmq

重启完成后，进入管理页面，点击交换机 Exchange，点开 Add a new exchange，查看交换机类型 Type，发现里面新增了 x-delayed-message 类型，则延时插件安装成功

3、测试延时消息

新建 SpringBoot 项目

    }
}

启动项目，会自动创建交换机和队列，进入管理页面查看交换机 exchange-delayed

运行测试

浏览器访问：http://localhost:8080/send

看控制台打印时间间隔

消费者端延时5秒钟收到消息

至此完
