文档很详细这里不再记录了。 1.2.使用rabbitmq
rabbitmq一般做消息队列用作为mqtt用我没有找到详细资料这里总结下使用方法
1.window安装rabbitmq 首先安装rabbitmq得依赖也就是opt_win64_24.0.exe,然后傻瓜式安装接可 安装完毕进入安装目录下sbin文件夹
1.浏览器查看插件 执行命令rabbitmq-plugins enable rabbitmq_management 回车浏览器输入http://127.0.0.1:15672/#/看到此页面及安装成功默认账号密码均是 guest 2.注意如果做mqtt使用的话需安装mqtt插件 安装命令rabbitmq-plugins enable rabbitmq_mqtt 执行完命令在浏览器上查看 mqtt及其端口号出现了的话就证明安装成功下面就可以开始整合了 2.linux安装rabbitmq
以前公司都是用window服务器没用过linux折腾了好久安装 erlang与rabbitmq不对应 不是最新 等等一系列问题最后看了一个视频 用 dock安装 根据官网docker run -it --rm --name rabbitmq -p 5672:5672 -p 15672:15672 rabbitmq:3-management 一句话就可以安装 如果后期需要安装插件docker exec 容器id rabbitmq-plugins enable rabbitmq_mqtt ps:查看容器id 方法1.使用docker ps -aqf “namecontainername” -------简短容器id 2.docker inspect --format{{.Id}} container_name -------详情容器id
带密码启动dockdocker run -it --rm --name rabbitmq -e RABBITMQ_DEFAULT_USERadmin -e RABBITMQ_DEFAULT_PASS密码 -p 15672:15672 -p 5672:5672 -p 1883:1883 rabbitmq:management15672 是rabbitmq management管理界面默认访问端口 5672 是amqp默认端口 1883 是mqtt tcp协议默认端口 15675 是web_mqtt ws协议默认端口 2.springboot集成mqtt
