搭建thingsboard物联网云平台花了大量时间，从小白到最后搭建成功，折磨了好几天，也感谢网友的帮助，提供了思路最终成功搞定，特此记录。

一、thingsboard环境搭建（Ubuntu20.04LTS）

参考官方文档，按部就班操作即可

http://www.ithingsboard.com/docs/user-guide/install/ubuntu/

二、thingsboard-gateway环境搭建

也是参考官方文档，直接安装

Step 1. Download the deb file

wget https://github.com/thingsboard/thingsboard-gateway/releases/latest/download/python3-thingsboard-gateway.deb

Step 2. Install the gateway using apt

Install ThingsBoard IoT Gateway as package and run it as daemon use the following command:

sudo apt install ./python3-thingsboard-gateway.deb -y

The deb package will automatically install the necessary libraries for the IOT Gateway to work:

System libraries: libffi-dev, libglib2.0-dev, libxml2-dev, libxslt-dev, libssl-dev, zlib1g-dev, python3-dev, python3-pip.
Python modules: importlib, importlib-metadata, jsonschema, pymodbus, lxml, jsonpath-rw, paho-mqtt, pyserial, PyYAML, simplejson, pyrsistent.

Step 3. Check gateway status

systemctl status thingsboard-gateway

修改配置文件：/etc/thingsboard-gateway/config/tb_gateway.json
