    这是一个创建于 1325 天前的主题,其中的信息可能已经有所发展或是发生改变。

    nutz 及 nutzboot 已支持 TDengine

    基于 nutzboot 开发 TDengine 实例

    开发环境

    • 服务端:CentOS 8.2 64 位

    • 客户端:Windows 10 64 位

    TDengine 安装及配置

    • 官网下载 rpm 安装包

    • 执行安装 rpm -ivh TDengine-server-2.0.18.0-Linux-x64.rpm

    • 修改配置文件 vi /etc/taos/taos.cfg 加上当前服务器 hostname 主机名

    # first fully qualified domain name (FQDN) for TDengine system
    firstEp                   wizzer-test:6030
    # local fully qualified domain name (FQDN)
    fqdn                      wizzer-test
    
    
    • 若为默认密码则直接输入 taostaos -h 127.0.0.1 执行数据库创建命令
    taos > create database test;
    

    Windows 10 hosts 配置

    • 修改 C:\Windows\System32\drivers\etc\hosts

    • 添加 ip wizzer-test

    创建 nutzboot Maven 项目

    • pom.xml 文件加入 nutzboot 及 TDengine JDBC 依赖
