這篇文章將為大家詳細(xì)講解有關(guān)如何在Docker中安裝MQTT,文章內(nèi)容質(zhì)量較高,因此小編分享給大家做個(gè)參考,希望大家閱讀完這篇文章后對(duì)相關(guān)知識(shí)有一定的了解。
MQTT簡介
MQTT(Message Queuing Telemetry Transport,消息隊(duì)列遙測(cè)傳輸)是IBM開發(fā)的一個(gè)即時(shí)通訊協(xié)議,有可能成為物聯(lián)網(wǎng)的重要組成部分。該協(xié)議支持所有平臺(tái),幾乎可以把所有聯(lián)網(wǎng)物品和外部連接起來,被用來當(dāng)做傳感器和制動(dòng)器(比如通過Twitter讓房屋聯(lián)網(wǎng))的通信協(xié)議。
Docker安裝RabbitMQ配置MQTT
使用RabbitMQ作為MQTT服務(wù)端,Eclipse Paho作為客戶端。宿主機(jī)系統(tǒng)為ubuntu16.04
Docker下載鏡像
docker pull daocloud.io/library/rabbitmq:3.7.4
啟動(dòng)RabbitMQ
docker run -d --hostname my-rabbit --name some-rabbit -p 15672:15672 -p 5672:5672 -p 1883:1883 -p 15675:15675 daocloud.io/library/rabbitmq:3.7.4
注意映射容器端口
15672 是rabbitmq management管理界面默認(rèn)訪問端口
5672 是amqp默認(rèn)端口
1883 是mqtt tcp協(xié)議默認(rèn)端口
15675 是web_mqtt websocket協(xié)議默認(rèn)端口
啟用插件
默認(rèn)安裝后我們需要手動(dòng)開啟rabbitmq_management插件,rabbitmq_mqtt插件和rabbitmq_web_mqtt插件。
執(zhí)行如下三條命令
docker exec <容器ID> rabbitmq-plugins enable rabbitmq_management docker exec <容器ID> rabbitmq-plugins enable rabbitmq_mqtt docker exec <容器ID> rabbitmq-plugins enable rabbitmq_web_mqtt
當(dāng)然你也可以寫個(gè)腳本start.sh,復(fù)制到容器中
/usr/sbin/rabbitmq-plugins enable rabbitmq_management /usr/sbin/rabbitmq-plugins enable rabbitmq_mqtt /usr/sbin/rabbitmq-plugins enable rabbitmq_web_mqtt
進(jìn)入容器執(zhí)行這個(gè)腳本。
sh start.sh
開放宿主機(jī)端口
firewall-cmd --zone=public --add-port=15672/tcp --permanent firewall-cmd --zone=public --add-port=5672/tcp --permanent firewall-cmd --zone=public --add-port=1883/tcp --permanent firewall-cmd --zone=public --add-port=15675/tcp --permanent firewall-cmd --reload
Python MQTT客戶端實(shí)現(xiàn)
安裝python包
pip install paho-mqtt
