thingsboard安装及配置

参考网址：https://thingsboard.io/docs/getting-started-guides/helloworld/

github地主：https://github.com/thingsboard/thingsboard

thingsboard使用了

actor模型:akka

用作服务调度:zookeeper

远程调用:gRPC,thrift

持久化:Cassandra（https://cassandra.apache.org/数据存储），datastax（数据访问）

演示环境：https://demo.thingsboard.io/login

服务端安装（rpm安装）：参考文档https://thingsboard.io/docs/user-guide/install/linux/(centos7)

1:thingsboard-1.3.rpm。下载地址https://github.com/thingsboard/thingsboard/releases/download/v1.3/thingsboard-1.3.rpm

2:sudo rpm -Uvh thingsboard-1.3.rpm,报错：java-1.8.0 is needed by thingsboard-0:1.3.0-1.noarch。猜测跟jdk的某些配置有关

sudo alternatives --config java

sudo alternatives --install /usr/bin/java java /usr/jdk1.8.0_60/bin/java 1，错误继续.删除配置

sudo alternatives --remove java /usr/jdk1.8.0_60/bin/java

下载rpm版的jdk安装文件(jdk-8u144-linux-x64.rpm)。

sudo rpm -Uvh jdk-8u144-linux-x64.rpm.sudo rpm -Uvh thingsboard-1.3.rpm执行成功

使用postgres数据库

# Install packages

sudo yum install postgresql-server postgresql-contrib

# Initialize your PostgreSQL DB

sudo postgresql-setup initdbsudo 

systemctl start postgresq

# Optional: Configure PostgreSQL to start on bootsudo 

systemctl enable postgresql

修改/var/lib/pgsql/data/postgresql.conf

listen_addresses = '*'    

修改pg_hba.conf 

host    all             all            x.x.x.x/32        md5。允许某个ip地址登录

host    all             all            127.0.0.1/32            trust.允许本机其他用户名登录

修改postgres密码

修改thingsboard.yml为postgres连接

启动postgres。systemctl start postgresql

sudo /usr/share/thingsboard/bin/install/install.sh --loadDemo

sudo systemctl start thingsboard.service.

服务端安装（maven build）：略。参考https://thingsboard.io/docs/user-guide/install/building-from-source/

git clone https://github.com/thingsboard/thingsboard.git

git checkout release-1.3

mvn clean package

客户端安装：安装mqtt，coap，http模拟器。参考https://thingsboard.io/docs/getting-started-guides/helloworld/#introduction

视个人情况安装nodejs，Mosquitto-client，curl。

npm install coap-cli -g 

npm install mqtt -g

创建mosquitto.repo源

[home_oojah_mqtt]name=mqtt (CentOS_CentOS-7)type=rpm-mdbaseurl=http://download.opensuse.org/repositories/home:/oojah:/mqtt/CentOS_CentOS-7/gpgcheck=1gpgkey=http://download.opensuse.org/repositories/home:/oojah:/mqtt/CentOS_CentOS-7//repodata/repomd.xml.keyenabled=1

yum search all mosquitto

模拟设备发送：下载模拟文件脚本，修改脚本变量，执行脚本。参考https://thingsboard.io/docs/getting-started-guides/helloworld/#introduction

mqtt.js/publish.js：模拟mqtt

var mqtt = require('mqtt');console.log('Connecting to: %s using access token: %s', process.env.THINGSBOARD_HOST, process.env.ACCESS_TOKEN);var client  = mqtt.connect('mqtt://'+ process.env.THINGSBOARD_HOST,{    username: process.env.ACCESS_TOKEN});client.on('connect', function () {    console.log('Client connected!');    client.publish('v1/devices/me/attributes', process.env.ATTRIBUTES);    console.log('Attributes published!');    client.publish('v1/devices/me/telemetry', process.env.TELEMETRY);    console.log('Telemetry published!');    client.end();});

模拟数据

attributes-data.json：

{"firmware_version":"1.0.1", "serial_number":"SN-001"}

telemetry-data.json 

{"temperature":21, "humidity":55.0, "active": false}

export THINGSBOARD_HOST=xxx.xxx.xxx.xxx
export ACCESS_TOKEN=xxxxxxx

export THINGSBOARD_PORT=xxxx

执行./coap-js.sh

或者./curl.sh

或者./mqtt-js.sh

或者./mosquitto.sh
