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：
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
bash
# 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
bash
### 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
bash
# 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
bash

forceReadConfig 1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）
第六步：创建数据库
sql
CREATE DATABASE energydb
KEEP 365
PAGES 256
PAGESIZE 16
COMP 2
DURATION 1
REPLICA 1;
第七步：创建用户及授权
sql
-- 1. 为不同角色创建专用用户
CREATE USER monitor PASS 'monitorM***2026#'; -- 监控用户
CREATE USER app_user PASS 'energyM***2026#'; -- 应用程序用户
CREATE USER analyst PASS 'analyst***2026#'; -- 数据分析用户
sql
GRANT READ, WRITE ON energydb TO app_user;
