## 一、前文 ##

> [TDengine 入门教程——导读][TDengine]

## 二、下载安装 ##

*  先下载安装包放到服务器上
 *  下载地址：[使用安装包立即开始 | TDengine 文档 | 涛思数据][_ TDengine _ _]

![在这里插入图片描述][add802e5f45e41d3a8deb3277f577729.png]

*  再rpm安装，`sudo rpm -ivh TDengine-server-<version>-Linux-x64.rpm`
 *  安装的时候，会跳出两个提示
    
     *  `Enter FQDN:port`，第一次安装，这个地方一定要直接回车跳过！
     *  `Enter your email address`，这个随意。

> sudo rpm -ivh TDengine-server-3.0.0.1-Linux-x64.rpm

> sudo rpm -ivh taosTools-2.1.2-Linux-x64.rpm

[root@iZ2ze30dygwd6yh7gu6lskZ ~]# sudo rpm -ivh TDengine-server-3.0.0.1-Linux-x64.rpm

    Start to install TDengine...
    
    System hostname is: iZ2ze30dygwd6yh7gu6lskZ
    
    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 iZ2ze30dygwd6yh7gu6lskZ to login into TDengine server
    
    
    TDengine is installed successfully!

## 三、启动taosd ##

>  *  systemctl start taosd
>  *  systemctl stop taosd
>  *  systemctl restart taosd

## 四、查看状态 ##

>  *  systemctl status taosd

[root@iZ2ze30dygwd6yh7gu6lskZ ~]# systemctl status taosd
    ● taosd.service - TDengine server service
       Loaded: loaded (/etc/systemd/system/taosd.service; enabled; vendor preset: disabled)
       Active: inactive (dead)
    [root@iZ2ze30dygwd6yh7gu6lskZ ~]# systemctl start taosd
    [root@iZ2ze30dygwd6yh7gu6lskZ ~]# systemctl status taosd
    ● taosd.service - TDengine server service
       Loaded: loaded (/etc/systemd/system/taosd.service; enabled; vendor preset: disabled)
       Active: active (running) since Wed 2022-09-07 09:45:11 CST; 4s ago

       Memory: 6.9M
       CGroup: /system.slice/taosd.service
               ├─14010 /usr/bin/taosd
               └─14017 /usr/bin/udfd -c /etc/taos
    
    Sep 07 09:45:11 iZ2ze30dygwd6yh7gu6lskZ systemd[1]: Starting TDengine server service...
    Sep 07 09:45:11 iZ2ze30dygwd6yh7gu6lskZ systemd[1]: Started TDengine server service.

## 五、命令行（CLI） ##

> taos

[root@iZ2ze30dygwd6yh7gu6lskZ ~]# taos
    Welcome to the TDengine Command Line Interface, Client Version:3.0.0.1
    Copyright (c) 2022 by TDengine, all rights reserved.
    
    Server is Community Edition.
    
    taos> exit

## 六、修改root密码 ##

*  刚安装好的TDengine是没有密码的，直接`taos`就能进入命令行（CLI）
 *  然后修改root账户的密码，`alter user root pass '123456';`
 *  具体查看：[TDengine 入门教程④——权限管理 | 用户增删改查，授权与撤销授权][TDengine _ _]

[root@VM-0-3-centos ~]# taos

       ******************************  Tab Completion  **********************************
       *   The TDengine CLI supports tab completion for a variety of items,             *
       *   including database names, table names, function names and keywords.          *
       *   The full list of shortcut keys is as follows:                                *
       *    [ TAB ]        ......  complete the current word                            *
       *                   ......  if used on a blank line, display all valid commands  *
       *    [ Ctrl + A ]   ......  move cursor to the st[A]rt of the line               *
       *    [ Ctrl + E ]   ......  move cursor to the [E]nd of the line                 *
       *    [ Ctrl + W ]   ......  move cursor to the middle of the line                *
       *    [ Ctrl + L ]   ......  clear the entire screen                              *
       *    [ Ctrl + K ]   ......  clear the screen after the cursor                    *
       *    [ Ctrl + U ]   ......  clear the screen before the cursor                   *
       **********************************************************************************
    
    Server is Community Edition.
    
    taos> show users;
               name           | super | enable | sysinfo |       create_time       |
    ================================================================================
     root                     |     1 |      1 |       1 | 2022-12-14 17:09:19.213 |

    taos> alter user root pass '123456';
    Query OK, 0 row(s) affected (0.001140s)
    
    taos> exit

*  修改root密码后，taos就不能直接进入命令行（CLI）了
 *  必须 taos -p，然后输入密码
