- 安装时序数据库
```
--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
```
"cloudgo": "0", //云端关系数据库是否开通
"shixugo": "1", //云端时序数据库是否开通
"groupid": "10", //集团编号
"projectid": "12", //集团项目编号
  "TDegnine": {
    "DataSource": "http://127.0.0.1:6041/rest/sql",
    "Username": "root",
    "Password": "taosdata",
    "Database": "rlq_jiaozhou_10_12",
    "PlanInterval": 5000,
    "CDataSource": "http://47.102.145.164:6020/rest/sql",
    "CUsername": "root",
    "CPassword": "taosdata",

  },
```
- 局域网时序数据库的原理
```
--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

-- 启动程序:dotnet DD.Local.Web.dll
-- 创建数据库:create database rlq_jiaozhou_10_12 KEEP 365;
-- 创建超级表
-- 确定超级表是否存在：show stables;
-- 创建所有SuperReal的子表
-- 确认子表是否创建：describe real_187ed532492c;
-- 开启本地时序
