--登录网址：https://www.taosdata.com/cn/getting-started/ --下载deb包 --确认安装位置：/home/dingding/下载/ --在下载位置打开命令行终端 --开始安装：sudo dpkg -i TDengine-server-2.0.13.0-Linux-x64.deb --检查状态：sudo systemctl status taosd --启动：sudo systemctl start taosd - 来到配置文件，查看配置:etc/taos/taos.cfg
时序数据库API地址：http://127.0.0.1:6020/rest/sql 时序数据库用户名：root 时序数据库密码：taosdata 时序数据库名称：rlq_jiaozhou_10_12(集团编号_项目编号) - 小试
create database db; show databases; use db; create table t(ts timestamp, cdata int); insert into t values ('2019-07-15 00:00:00'); select * from t; - 应用程序配置连接字符串

--RealDataToTDengine,每5分钟运行一次 --时序数据库 --时序超级表 --时序子表修改RealDataToTDengine，只支持本地数据库
修改批量创建子表：ShiXuChild
修改创建超级表：SuperTable
开始实施 ``` --更新程序 --更新设置，除了shixugo之外的先更新
