【最佳实践】TDengine 3.3.6.13安装---RPM包安装、开源版本下载、TDengine基本操作

news 2026/6/3 23:07:01

软件环境

1、操作系统：CentOS Linux release 7.9.2009(Core) -- 阿里服务器上选的CentOS镜像

说明：

Alibaba Cloud Linux 4 LTS 64位的操作系统与TDengine的兼容性会差一些，作者已经试过了

2、TDengine 3.3.6.13 TDengine3.3.6.13官方下载地址

安装步骤

第一步：下载TDengine RPM安装包（开源版本）

https://www.taosdata.com/assets-download/3.0/TDengine-server-3.3.6.13-Linux-x64.rpm

TDengine下载中心：

https://www.taosdata.com/download-center?product=TDengine+TSDB-OSS&version=3.3.6.13&platform=Linux-Generic&architecture=x64

说明：

OSS 是 “Open Source Software”（开源软件）的缩写
TDengine IDMP 是一款涛思数据上线的 AI 原生的工业数据管理平台
TDengine Historian：IDMP + TSDB + TDgpt 一体化安装包，提供物联网和工业数据管理、时序存储与 AI 智能分析的统一部署方案

第二步：安装/更新依赖包

直接执行即可，省去不少麻烦

# 安装基础依赖 yum install -y glibc-langpack-en nss curl openssl libuuid-devel # 安装开发工具（修复依赖问题） yum groupinstall -y "Development Tools" 检查 glibc 版本（要求 >= 2.17） ldd --version | head -1 # 更新 glibc（如果版本过低） yum update -y glibc

第三步：设置locale

### 检查当前系统 locale 配置 locale -a # 查看已安装的locale locale # 查看当前locale设置 ## 设置locale为en_US.UTF-8 localedef -i en_US -f UTF-8 en_US.UTF-8 ### 验证 locale 是否生效 locale -a | grep en_US.UTF-8

第四步：安装TDengine

# 执行安装 rpm -ivh TDengine-server-3.3.6.13-Linux-x64.rpm

Enter FQDN:port→ 直接回车（单机部署）
Enter email address→ 直接回车跳过

第五步：配置taos.cfg

核心配置说明：

1、ip使用内部ip（不要使用外网IP，这是新手容易犯错的地方）

2、dataDir /var/lib/taos # 数据目录

3、tempDir /tmp/ # 临时文件目录

4、supportVnodes 9 # 可以使用cpu核心数*2，有的配 CPU*2+5，大家随意

5、forceReadConfig 1 # 这个很重要，反正作者使用默认值0时，死活都读不到配置（因为show dnodes 显示可用的Vnodes为0，改为1后supportVnodes的9就生效了）

服务启动

rpm包安装完下面的命令默认在环境变量中

start-all.sh

服务停止

stop-all.sh

命令行使用

登陆

taos -h 8.153.109.123 -u root -proo*****#!

创建数据库

CREATE DATABASE energydb KEEP 365 PAGES 256 PAGESIZE 16 COMP 2 DURATION 1 REPLICA 1;

附件一：TDengine基本操作

TDengine 基本操作围绕“超级表（STable）+ 子表”数据模型，使用标准 SQL 进行建模、写入与查询。核心命令如下：‌‌

‌创建数据库‌：CREATE DATABASE db_name KEEP 365;（KEEP设定数据保留天数）
‌创建超级表‌：CREATE STABLE meters (ts TIMESTAMP, current FLOAT, voltage INT) TAGS (location BINARY(64), groupId INT);（首列必为TIMESTAMP，TAGS 定义标签）
‌创建子表‌：CREATE TABLE m1 USING meters TAGS ('beijing', 1);
‌插入数据‌：INSERT INTO m1 VALUES (now, 10.3, 219, 0.32);或批量插入多行/多表
‌查询数据‌：标准 SQL，如SELECT * FROM meters WHERE ts > NOW - 1d;或聚合SELECT AVG(current) FROM meters INTERVAL(1h);
‌查看对象‌：SHOW DATABASES;/SHOW STABLES;/SHOW TABLES;/DESCRIBE m1;
‌删除对象‌：DROP TABLE m1;或DROP STABLE meters;（会删所有子表） ‌‌

操作需通过 ‌taosCLI‌（命令行）、‌taosX‌（GUI）或 ‌RESTful API‌（端口 6041）执行。TDengine 默认使用root/taosdata登录，支持类标准 SQL（无 UPDATE/DELETE，但可覆盖同主键时间戳记录）。时序查询常结合INTERVAL（时间窗口）、FILL（空值填充）和GROUP BY tags（按设备/位置分组）。‌‌

如刚部署，建议用 Docker 快速启动：docker run -d --name tdengine -p 6030:6030 -p 6041:6041 tdengine/tdengine:3.3.6.0，再用taos -h localhost连接
