docker运行rabbitmq，mq用户以及vhost的持久化方法

一、编写dockerfile文件，配置需要的插件

vim package/dockerfile-rabbitmq.yaml
FROM rabbitmq:3.8.5
WORKDIR /var/lib/rabbitmq
COPY rabbitmq_delayed_message_exchange-3.8.0.ez /opt/rabbitmq/plugins/
RUN chown rabbitmq:rabbitmq /opt/rabbitmq/plugins/rabbitmq_delayed_message_exchange-3.8.0.ez
RUN chmod 644 /opt/rabbitmq/plugins/rabbitmq_delayed_message_exchange-3.8.0.ez
RUN rabbitmq-plugins enable --offline rabbitmq_delayed_message_exchange
RUN rabbitmq-plugins enable --offline rabbitmq_management
RUN rabbitmq-plugins enable --offline rabbitmq_web_stomp
RUN rabbitmq-plugins enable --offline rabbitmq_web_mqtt

二、编写docker-compose文件，设置需要持久化的目录

vim docker-compose-rabbitmq.yaml 
version: "3.3"

networks:
  default:
    external: true
    name: learn-network

services:
  learn-rabbitmq:
    image: learn/rabbitmq:3.8.5
    hostname: rabbitmq
    container_name: learn-rabbitmq
    restart: always
    ports:
      - "6672:6672"
      - "15672:15672"
      - "25672:25672"
      - "15674:15674"
      - "15675:15675"
      - "1883:1883"
      - "61613:61613"
    volumes:
      #- /etc/hosts:/etc/hosts
      - /etc/localtime:/etc/localtime
      - ./config/rabbitmq/rabbitmq.conf:/etc/rabbitmq/rabbitmq.conf
      - ./data/rabbitmq:/var/lib/rabbitmq

这里的hostname用于配置容器主机名，这样才能保证每次容器启动时主机名一致，持久化的mq配置数据库目录是同一个，才能保证数据的持久化

三、docker-compose 启动容器

docker-compose -f docker-compose-rabbitmq.yaml up -d

四、进入容器进行用户和vhost的相关配置

docker exec -it learn-rabbitmq /bin/bash
rabbitmqctl add_user hlmq xxxxxxx
rabbitmqctl set_user_tags hlmq administrator 
rabbitmqctl set_permissions -p / hlmq '.*' '.*' '.*'
rabbitmqctl add_vhost im
rabbitmqctl set_permissions -p im hlmq '.*' '.*' '.*'

配置完后，所有的数据都持久化到宿主机对应的目录下了

五、停止删除容器，并重新启动进入容器验证

docker stop learn-rabbitmq && docker rm -f learn-rabbitmq
docker-compose -f docker-compose-rabbitmq.yaml up -d
docker exec -it learn-rabbitmq /bin/bash

root@rabbitmq:~# rabbitmqctl list_users
Listing users ...
user tags
hlmq [administrator]
guest [administrator]
