本文通过docker-compose构建一个单体的rabbtimq容器。
1，docker、docker-compose环境
首先需要有docker和docker-compose环境，docker安装[1]，docker-compose安装[2]。
通过下列命令确定docker、docker-compose是否安装成功。
[root@192 gengzhihao]# docker version

Docker Compose version v2.24.62，构建dockerfile，启动容器
docker-compose在/usr/local/bin里，我们就在/usr/local下构建一个docker-compose目录，里面再构建各级不同容器的目录，用于构建dockerfile和挂载目录[3]。
[root@192 bin]# cd /usr/local
[root@192 local]# ls
bin docker-mount etc games include lib lib64 libexec mongodb mycat mysql sbin share src
[root@192 local]# mkdir docker-compose
[root@192 local]# ls
bin docker-mount games lib libexec mycat sbin src
docker-compose etc include lib64 mongodb mysql share
[root@192 local]# cd docker-compose/
[root@192 docker-compose]# mkdir rabbitmq
[root@192 docker-compose]# cd rabbitmq/在其中构建dockerfile
[root@192 rabbitmq]# vim docker-compose.yml
内容如下：
version: '3.1'
services:rabbitmq:restart: alwaysimage: daocloud.io/library/rabbitmq:3.8.8volumes:- ./data/:/var/lib/rabbitmq/- ./log/:/var/log/rabbitmq/log/ports:- 15672:15672- 5672:5672启动rabbitmq的容器，curl其端口看一下是否正常返回AMQP，docker ps看一下容器名字是什么，后面进入容器内部用得上。
[root@192 rabbitmq]# docker-compose up -d

解决方法就是多试几次命令就好[4]。
3，进入容器，配置可视化界面
进入容器，进入其/opt/rabbitmq目录，其中plugins和sbin目录书我们需要注意的。进入容器时用到的容器名字，是docker ps时查看到的rabbitmq容器的名字。
[root@192 rabbitmq]# docker exec -it rabbitmq-rabbitmq-1 /bin/bash
root@39dc5f01ded3:/# cd /opt/rabbitmq/
root@39dc5f01ded3:/opt/rabbitmq# ls
