安装环境
安装JDK
安装前需要保证设备上配有 JDK>=1.8 的运行环境，并配置好 JAVA_HOME 环境变量。
设置最大文件打开数为 65535
-
编辑 /etc/security/limits.conf 文件：
打开终端，使用文本编辑器编辑
/etc/security/limits.conf文件。你可以使用vim、nano或其他你喜欢的编辑器。sudo nano /etc/security/limits.conf -
添加以下行到文件末尾：
在文件的末尾添加以下行：
* soft nofile 65535 * hard nofile 65535这将设置所有用户的软限制和硬限制都为65535。
-
编辑 /etc/security/limits.d/20-nproc.conf 文件（如果存在）：
sudo nano /etc/security/limits.d/20-nproc.conf如果该文件存在，请注释掉或删除以下行：
* soft nproc 4096注释的方式是在行首添加
#。 -
编辑 /etc/sysctl.conf 文件：
sudo nano /etc/sysctl.conf在文件末尾添加以下行：
fs.file-max = 65535保存并关闭文件。
-
执行 sysctl 命令使更改生效：
sudo sysctl -p这会重新加载 sysctl.conf 文件以应用更改。
安装服务
解压
unzip apache-iotdb-1.2.2-all-bin.zip
进入目录
cd apache-iotdb-1.2.2-all-bin
目录结构如下
- sbin 启动和停止脚本目录
- conf 配置文件目录
- tools 系统工具目录
- lib 依赖包目录
启动 IoTDB
IoTDB 是一个基于分布式系统的数据库。要启动 IoTDB ，你可以先启动单机版（一个 ConfigNode 和一个 DataNode）来检查安装。
用户可以使用 sbin 文件夹下的 start-standalone 脚本启动 IoTDB。
bash sbin/start-standalone.sh
注意：目前，要使用单机模式，你需要保证所有的地址设置为 127.0.0.1，如果需要从非 IoTDB 所在的机器访问此IoTDB，请将配置项 dn_rpc_address 修改为 IoTDB 所在的机器 IP。副本数设置为1。并且，推荐使用 SimpleConsensus，因为这会带来额外的效率。这些现在都是默认配置。
使用 Cli 工具
IoTDB 为用户提供多种与服务器交互的方式，在此我们介绍使用 Cli 工具进行写入、查询数据的基本步骤。
初始安装后的 IoTDB 中有一个默认用户：root，默认密码为 root。用户可以使用该用户运行 Cli 工具操作 IoTDB。Cli 工具启动脚本为 sbin 文件夹下的 start-cli 脚本。启动脚本时需要指定运行 ip、port、username 和 password。若脚本未给定对应参数，则默认参数为-h 127.0.0.1 -p 6667 -u root -pw -root
以下启动语句为服务器在本机运行，且用户未更改运行端口号的示例。
bash sbin/start-cli.sh -h 127.0.0.1 -p 6667 -u root -pw root
启动后出现如图提示即为启动成功。

IoTDB 的基本操作
在这里，我们首先介绍一下使用 Cli 工具创建时间序列、插入数据并查看数据的方法。
数据在 IoTDB 中的组织形式是以时间序列为单位，每一个时间序列中有若干个数据-时间点对，每一个时间序列属于一个 database。在定义时间序列之前，要首先使用 CREATE DATABASE 语句创建数据库。SQL 语句如下：
创建数据库
CREATE DATABASE root.ln
查看所有数据库
SHOW DATABASES
创建时间序列
Database 设定后，使用 CREATE TIMESERIES 语句可以创建新的时间序列，创建时间序列时需要定义数据的类型和编码方式。此处我们创建两个时间序列，SQL 语句如下：
IoTDB> CREATE TIMESERIES root.ln.wf01.wt01.status WITH DATATYPE=BOOLEAN, ENCODING=PLAIN
IoTDB> CREATE TIMESERIES root.ln.wf01.wt01.temperature WITH DATATYPE=FLOAT, ENCODING=RLE
为了查看指定的时间序列，我们可以使用 SHOW TIMESERIES 语句，其中、 表示时间序列对应的路径，默认值为空，表示查看系统中所有的时间序列。下面是两个例子：
使用 SHOW TIMESERIES 语句查看系统中存在的所有时间序列，SQL 语句如下：
IoTDB> SHOW TIMESERIES
+-----------------------------+-----+--------+--------+--------+-----------+----+----------+--------+------------------+--------+
| Timeseries|Alias|Database|DataType|Encoding|Compression|Tags|Attributes|Deadband|DeadbandParameters|ViewType|
+-----------------------------+-----+--------+--------+--------+-----------+----+----------+--------+------------------+--------+
|root.ln.wf01.wt01.temperature| null| root.ln| FLOAT| RLE| LZ4|null| null| null| null| BASE|
| root.ln.wf01.wt01.status| null| root.ln| BOOLEAN| PLAIN| LZ4|null| null| null| null| BASE|
+-----------------------------+-----+--------+--------+--------+-----------+----+----------+--------+------------------+--------+
Total line number = 2
It costs 0.569s
查看具体的时间序列 root.ln.wf01.wt01.status 的 SQL 语句如下：
IoTDB> SHOW TIMESERIES root.ln.wf01.wt01.status
+------------------------+-----+--------+--------+--------+-----------+----+----------+--------+------------------+--------+
| Timeseries|Alias|Database|DataType|Encoding|Compression|Tags|Attributes|Deadband|DeadbandParameters|ViewType|
+------------------------+-----+--------+--------+--------+-----------+----+----------+--------+------------------+--------+
|root.ln.wf01.wt01.status| null| root.ln| BOOLEAN| PLAIN| LZ4|null| null| null| null| BASE|
+------------------------+-----+--------+--------+--------+-----------+----+----------+--------+------------------+--------+
Total line number = 1
It costs 0.093s
插入时间序列数据
接下来，我们使用 INSERT 语句向 root.ln.wf01.wt01.status 时间序列中插入数据，在插入数据时需要首先指定时间戳和路径后缀名称：
INSERT INTO root.ln.wf01.wt01(timestamp,status) values(100,true);
我们也可以向多个时间序列中同时插入数据，这些时间序列同属于一个时间戳：
INSERT INTO root.ln.wf01.wt01(timestamp,status,temperature) values(200,false,20.71)
查询数据
最后，我们查询之前插入的数据。使用 SELECT 语句我们可以查询指定的时间序列的数据结果，SQL 语句如下：
SELECT status FROM root.ln.wf01.wt01
查询结果如下：
IoTDB> SELECT status FROM root.ln.wf01.wt01
+-----------------------------+------------------------+
| Time|root.ln.wf01.wt01.status|
+-----------------------------+------------------------+
|1970-01-01T08:00:00.100+08:00| true|
|1970-01-01T08:00:00.200+08:00| false|
+-----------------------------+------------------------+
Total line number = 2
It costs 0.378s
我们也可以查询多个时间序列的数据结果，SQL 语句如下：
SELECT * FROM root.ln.wf01.wt01
查询结果如下：
IoTDB> SELECT * FROM root.ln.wf01.wt01
+-----------------------------+-----------------------------+------------------------+
| Time|root.ln.wf01.wt01.temperature|root.ln.wf01.wt01.status|
+-----------------------------+-----------------------------+------------------------+
|1970-01-01T08:00:00.100+08:00| null| true|
|1970-01-01T08:00:00.200+08:00| 20.71| false|
+-----------------------------+-----------------------------+------------------------+
Total line number = 2
It costs 0.213s
退出会话
输入 quit 或 exit 可退出 Cli 结束本次会话。
IoTDB> quit
或者
IoTDB> exit
停止 IoTDB
用户可以使用$IOTDB_HOME/sbin 文件夹下的 stop-standalone 脚本停止 IoTDB。
Linux 系统与 MacOS 系统停止命令如下：
> sudo bash sbin/stop-standalone.sh

创建数据库
create database root.test
将元数据模板添加到数据库
set schema template test1127 to root.test
插入数据
INSERT INTO root.test.chexing2.chexi4(timestamp,a,b,d) values(1700000000000,1.2,false,‘你费老金了’)
INSERT INTO root.test.chexing1.chexi4(timestamp,a,b,d) values(1700000000000,1.2,false,‘你费老金了’)
…
此时添加的数据，都会使用元数据模板设置的元数据类型
查询数据
SELECT * FROM root.test.chexing1.chexi1
