一、编写Dockerfile
# 使用带有管理插件的官方 RabbitMQ 镜像作为基础
FROM rabbitmq:3.9-management
# 复制自定义模板文件到 RabbitMQ 管理插件的模板目录
# 这里假设 ./users.ejs 和 ./limits.ejs 是用于自定义管理界面的模板文件
COPY ./users.ejs /opt/rabbitmq/plugins/rabbitmq_management-3.9.29/priv/www/js/tmpl
COPY ./limits.ejs /opt/rabbitmq/plugins/rabbitmq_management-3.9.29/priv/www/js/tmpl
# 设置环境变量 ACTIVEMQ_HOME，虽然这里与 RabbitMQ 无关，但保留原样
ENV ACTIVEMQ_HOME /mydocker/activemq
# 更新 apt 包列表，并安装 curl 工具，用于下载插件
RUN apt-get -o Acquire::Check-Date=false update && apt-get install -y curl
# 下载延迟消息交换插件
# 将插件下载到 RabbitMQ 的 plugins 目录下
RUN curl -L https://github.com/rabbitmq/rabbitmq-delayed-message-exchange/releases/download/3.9.0/rabbitmq_delayed_message_exchange-3.9.0.ez > $RABBITMQ_HOME/plugins/rabbitmq_delayed_message_exchange-3.9.0.ez
# 更改插件文件的所有者，确保 RabbitMQ 用户可以访问和管理插件
RUN chown rabbitmq:rabbitmq $RABBITMQ_HOME/plugins/rabbitmq_delayed_message_exchange-3.9.0.ez
# 启用延迟消息交换插件
RUN rabbitmq-plugins enable rabbitmq_delayed_message_exchange上传Dockerfile 和自定义模版，自行下载。上传到服务器
二、构建镜像
用上面Dockerfile 打包为本地镜像
docker build -t my-rabbitmq .
执行结果如下：

三、运行镜像
docker run -d -p 15672:15672 -p 5672:5672 \
-e RABBITMQ_DEFAULT_VHOST=my_vhost \
-e RABBITMQ_DEFAULT_USER=admin \
-e RABBITMQ_DEFAULT_PASS=admin \
--hostname myRabbit \
--name rabbitmq \
my-rabbitmq
设置rabbitmq 自动启
docker update rabbitmq --restart=always四、启动 rabbitmq_management
方法一：
docker exec -it rabbitmq /bin/bash
---------------------------------
rabbitmq-plugins enable rabbitmq_management
方法二：：
docker exec -it rabbitmq rabbitmq-plugins enable rabbitmq_management
五、测试访问 RabbitMQ
浏览器输入地址：http://ip:15672 即可访问后台管理页面，如下：
注意： 由于我在启动容器的时候设置了默认的用户名 (Admin) 和密码 (Admin)，所以需要使用设置的用户名和密码进行登录。
登录进去后的管理页面如下：
提示： 如果无法访问可以尝试开启防火墙 15672 端口：
firewall-cmd --zone=public --add-port=15672/tcp --permanent
firewall-cmd --reload
