服务端TDengine设备

依据文档推荐，现在支撑linux裸机设备，不建议docker设备，所以咱们这儿裸机设备

1.通过这个https://www.taosdata.com/assets-download/TDengine-server-2.2.0.5-Linux-x64.deb链接下载设备文件

2.放置此文件到192.168.0.13服务器上，通过指令sudo dpkg -i TDengine-server-2.2.0.5-Linux-x64.deb 设备

3.通过指令发动TDengine数据库sudo systemctl start taosd

4.参阅https://www.taosdata.com/cn/getting-started/#Quick%20Start上的指令可以去创立数据库和表检验

python客户端容器

以python做一个docker容器为例。这儿有一个很奇葩的地方，每一种TDengine的联接方法都必须要设置一个taos.cfg的途径，和设备一个独立的客户端程序

创立一个Dockerfile和一个检验文件sub.py ，一个requirements.txt文件，假如不用faker库，requirements.txt文件也不需要

Dockerfile内容如下

FROM python:3.9.7 ADD . . RUN wget https://www.taosdata.com/assets-download/TDengine-client-2.2.0.5-Linux-x64.tar.gz RUN tar -xzf TDengine-client-2.2.0.5-Linux-x64.tar.gz WORKDIR /TDengine-client-2.2.0.5 RUN ./install_client.sh WORKDIR / RUN git clone --depth 1 https://github.com/taosdata/TDengine.git RUN pip install -r requirements.txt  -i https://pypi.tuna.tsinghua.edu.cn/simple RUN pip install ./TDengine/src/connector/python -i https://pypi.tuna.tsinghua.edu.cn/simple CMD ["python","test.py"]

检验主文件test.py
