记录一下使用Ubuntu系统的安装TDengine Database管理软件工具
先查看一下系统的版本，可以看到这里使用的是Ubuntu20.04版本，版本代号focal

linux环境
使用deb安装
首先去下载deb安装包 有2个(其中taosTools是工具，TDengine-server是时序数据库)，下载需要输入邮箱 ，然后从邮箱获取下载链接，记录一下我安装的版本和工具版本
https://www.taosdata.com/assets-download/3.0/TDengine-server-3.2.2.0-Linux-x64.deb
https://www.taosdata.com/assets-download/3.0/taosTools-2.5.2-Linux-x64-comp3.deb
win系统客户端
https://www.taosdata.com/assets-download/3.0/TDengine-client-3.2.2.0-Windows-x64.exe
将下载的安装包放置在ubuntu的home指定的用户下面(安装需要进入deb包的目录) 我这里是/home/myw
/home/myw
安装指令(在deb文件包的目录下面)
sudo dpkg -i TDengine-server-3.2.2.0-Linux-x64.deb
myw@myw-S451LN:~$ sudo dpkg -i TDengine-server-3.2.2.0-Linux-x64.deb
[sudo] myw 的密码：

System hostname is: myw-S451LN
Enter FQDN:port (like h1.taosdata.com:6030) of an existing TDengine cluster node to join
OR leave it blank to build one:
Enter your email address for priority support or enter empty to skip:
Created symlink /etc/systemd/system/multi-user.target.wants/taosd.service → /etc/systemd/system/taosd.service.
To configure TDengine : edit /etc/taos/taos.cfg
To start TDengine : sudo systemctl start taosd
To access TDengine : taos -h myw-S451LN to login into TDengine server
TDengine is installed successfully!

安装过程中有2个停顿 直接enter
启动停止重启，查看是否启动成功 默认端口是6030
