用docker部署RabbitMQ环境的详细介绍

前置条件：

已经安装好docker

1.查找镜像（有2种方式）

①登录rabbitmq官网找到docker镜像，选择想要的镜像的tag

https://www.rabbitmq.com/download.html

https://hub.docker.com/_/rabbitmq

如果需要访问web管理页面，就选择tag为management的

ps：带有alpine的是用最小linux镜像构建的，体积最小可以达5M初学者不建议这么折腾，而且 Alpine Linux使用了muslmusl实现的DNS服务不会使用resolv.conf文件中的search和domain两个配置，通过DNS来进行服务发现时需要注意。,带有-management的是带有web控制台

②直接用docker search 搜索，默认下载标签为latest的镜像（无法打开web管理页面）

ps：如果是普通用户登录，需要sudo，不然会提示错误

[testhadoop@sz-145-centos101 ~]$ docker search rabbitmq
Get http:///var/run/docker.sock/v1.19/images/search?term=rabbitmq: dial unix /var/run/docker.sock: permission denied. Are you trying to connect to a TLS-enabled daemon without TLS?

2.下载镜像（有时候网络问题超时，多尝试几次即可。我这里选择的是可以访问web管理界面的tag）

sudo docker pull rabbitmq:management

3.创建容器并运行（15672是管理界面的端口，5672是服务的端口。这里顺便将管理系统的用户名和密码设置为admin admin）

docker run -dit --name Myrabbitmq -e RABBITMQ_DEFAULT_USER=admin -e RABBITMQ_DEFAULT_PASS=admin -p 15672:15672 -p 5672:5672 rabbitmq:management
