Centos 7 二进制安装时序数据库TDengine_我和国产时序数据库的第一次亲密接触

一、前言

之前在搞监控时，曾学习和测试过InfluxDB数据库，第一次接触时序数据库，也深深感受到了时序数据库的块，最近在墨天轮上看到对国产库时序数据库（Time Series Database）的介绍，特别是看了涛思数据库创世人陶总的采访，真的挺钦佩陶总的三次创业历程，现在又把涛思数据库搞的这么好。也很想好好了解和学习下这款国产时序数据库，也希望能和InfluxDB数据库做个对比，希望能在后面的一些项目中使用该数据库，于是在公司测试环境尝试使用二进制安装测试下该数据库。

二、安装数据库

本次安装所选用的操作系统是Centos 7.9 x86_64位操作系统，使用root用户安装。

2.1 下载安装包

登录TDengine数据库官网(https://www.taosdata.com/)

点击产品，如下图，

选择“TDengine 社区版”,

选择“快速上手”，

选择“安装包”，然后选择tar.gz安装，然后点击“TDengine-server-3.0.4.2-Linux-x64.tar.gz”下载。

弹出一个对话框，根据要求填写邮箱地址，

然后点击“下载”，会弹出一个信息框，如下，

然后打开邮箱，查看接收到的邮件信息，如下：

然后点击“这个链接”按钮，就会下载二进制安装包。

1.2 安装数据库

将下载好的安装包TDengine-server-3.0.4.2-Linux-x64.tar.gz上传至服务器某个目录下，比如/home/soft目录下，解压数据库安装包。

1）解压安装包

# 解压数据库安装包 使用-v参数可以详细查看安装包都含哪些具体信息
[root@xsky-node4 soft]# tar -zxvf TDengine-server-3.0.4.2-Linux-x64.tar.gz

2）安装数据库

[root@xsky-node4 soft]# cd TDengine-server-3.0.4.2
[root@xsky-node4 TDengine-server-3.0.4.2]# ./install.sh -e no
Start to update TDengine...
Created symlink from /etc/systemd/system/multi-user.target.wants/taosd.service to /etc/systemd/system/taosd.service.To configure TDengine : edit /etc/taos/taos.cfg
To configure taos Adapter : edit /etc/taos/taosadapter.toml
To start TDengine     : sudo systemctl start taosd
To start taos Adapter : sudo systemctl start taosadapter 
To access TDengine    : use taos -h xsky-node4 in shellTDengine is updated successfully!
Install taoskeeper as a standalone service
taoskeeper is installed, enable it by `systemctl enable taoskeeper`

3）启动数据库

启动服务进程：systemctl start taosd
停止服务进程：systemctl stop taosd
重启服务进程：systemctl restart taosd
查看服务状态：systemctl status taosd

# 使用root用户启动服务
[root@xsky-node4 TDengine-server-3.0.4.2]# systemctl enable taoskeeper

4）使用数据库

TDengine提供了taos这一CLI命令行工具可以方便登录数据库，要登录数据库，执行执行 taos命令即可，登录成功会显示如下信息。

登录数据库后，可使用命令执行创建/删除/查询数据库及表操作。

[root@xsky-node4 TDengine-server-3.0.4.2]# taos
read /etc/localtime error, reason:Invalid argumentThere is not /etc/timezone.
