官网下载jdk-1.8，下载页面：https://www.oracle.com/java/technologies/javase/javase-jdk8-downloads.html
安装，配置环境变量，把jdk加入到环境变量里。
命令行内查看java的版本。
```shell
>java -version
java version "1.8.0_131"
Java(TM) SE Runtime Environment (build 1.8.0_131-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)
```
（2）安装配置maven
官网下载maven，下载地址：http://maven.apache.org/download.cgi
配置环境变量MAVEN_HOME，将MAVEN_HOME/bin添加到PATH
命令行里查看maven的版本
```shell
>mvn --version
Apache Maven 3.5.0 (ff8f5e7444045639af65f6095c62210b5713f426; 2017-04-04T03:39:06+08:00)
Maven home: D:\apache-maven-3.5.0\bin\..
Java version: 1.8.0_131, vendor: Oracle Corporation
Java home: C:\Program Files\Java\jdk1.8.0_131\jre
Default locale: zh_CN, platform encoding: GBK
OS name: "windows 10", version: "10.0", arch: "amd64", family: "windows"
```
为了加快maven下载依赖的速度，可以为maven配置mirror，修改MAVEN_HOME\config\settings.xml文件
```xml
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
<!-- 配置本地maven仓库的路径 -->
<localRepository>D:\apache-maven-localRepository</localRepository>
<mirrors>
<!-- 配置阿里云Maven镜像仓库 -->
<mirror>
<id>alimaven</id>
<name>aliyun maven</name>
<url>http://maven.aliyun.com/nexus/content/groups/public/</url>
<mirrorOf>central</mirrorOf>
</mirror>
</mirrors>
<profiles>
<!-- 配置jdk，maven会默认使用java1.8 -->
<profile>
<id>jdk-1.8</id>
<activation>
<activeByDefault>true</activeByDefault>
<jdk>1.8</jdk>
</activation>
<properties>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
<maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>
</properties>
</profile>
</profiles>
</settings>
```
（3）在linux服务器上安装TDengine-server
在taosdata官网下载TDengine-server，下载地址：https://www.taosdata.com/cn/all-downloads/
在linux服务器上安装TDengine-server
```shell
# tar -zxvf package/TDengine-server-2.0.1.1-Linux-x64.tar.gz
# cd TDengine-server/
# ./install.sh
```
启动taosd
```shell
# systemctl start taosd
```
在server上用taos连接taosd
```shell
# taos
taos> show dnodes;
id | end_point | vnodes | cores | status | role | create_time |
==================================================================================================================
1 | td01:6030 | 2 | 4 | ready | any | 2020-08-19 18:40:25.045 |
Query OK, 1 row(s) in set (0.005765s)
```
如果可以正确连接到taosd实例，并打印出databases的信息，说明TDengine的server已经正确启动。这里查看server的hostname
```shell
# hostname -f
td01
```
注意，如果安装TDengine后，使用默认的taos.cfg配置文件，taosd会使用当前server的hostname创建dnode实例。之后，在client也需要使用这个hostname来连接taosd。
（4）在windows上安装TDengine-client
在taosdata官网下载taos客户端，下载地址：
https://www.taosdata.com/cn/all-downloads/
下载后，双击exe安装。
修改client的hosts文件（C:\Windows\System32\drivers\etc\hosts），将server的hostname和ip配置到client的hosts文件中
```
192.168.236.136 td01
```
配置完成后，在命令行内使用taos shell连接server端
```shell
C:\TDengine>taos -h td01
Welcome to the TDengine shell from Linux, Client Version:2.0.1.1
Copyright (c) 2017 by TAOS Data, Inc. All rights reserved.
taos> show databases;
name | created_time | ntables | vgroups | replica | quorum | days | keep0,keep1,keep(D) | cache(MB) | blocks | minrows | maxrows | wallevel | fsync | comp | precision | status |
===================================================================================================================================================================================================================================================================
test | 2020-08-19 18:43:50.731 | 1 | 1 | 1 | 1 | 2 | 3650,3650,3650 | 16 | 6 | 100 | 4096 | 1 | 3000 | 2 | ms | ready |
log | 2020-08-19 18:40:28.064 | 4 | 1 | 1 | 1 | 10 | 30,30,30 | 1 | 3 | 100 | 4096 | 1 | 3000 | 2 | us | ready |
Query OK, 2 row(s) in set (0.068000s)
```
如果windows上的client能够正常连接，并打印database信息，说明client可以正常连接server了。
## 应用开发
（1）新建maven工程，在pom.xml中引入taos-jdbcdriver依赖。
```xml
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.taosdata.demo</groupId>
<artifactId>JdbcDemo</artifactId>
<version>1.0-SNAPSHOT</version>
<dependencies>
<dependency>
<groupId>com.taosdata.jdbc</groupId>
<artifactId>taos-jdbcdriver</artifactId>
<version>2.0.8</version>
</dependency>
</dependencies>
</project>
```
（2）使用jdbc查询TDengine数据库
下面是示例代码：
```java
public class JdbcDemo {
public static void main(String[] args) throws Exception {
Connection conn = getConn();
Statement stmt = conn.createStatement();
// create database
stmt.executeUpdate("create database if not exists db");
// use database
stmt.executeUpdate("use db");
// create table
stmt.executeUpdate("create table if not exists tb (ts timestamp, temperature int, humidity float)");
// insert data
int affectedRows = stmt.executeUpdate("insert into tb values(now, 23, 10.3) (now + 1s, 20, 9.3)");
System.out.println("insert " + affectedRows + " rows.");
// query data
ResultSet resultSet = stmt.executeQuery("select * from tb");
Timestamp ts = null;
int temperature = 0;
float humidity = 0;
while(resultSet.next()){
ts = resultSet.getTimestamp(1);
temperature = resultSet.getInt(2);
humidity = resultSet.getFloat("humidity");
System.out.printf("%s, %d, %s\n", ts, temperature, humidity);
}
}
public static Connection getConn() throws Exception{
Class.forName("com.taosdata.jdbc.TSDBDriver");
String jdbcUrl = "jdbc:TAOS://td01:0/log?user=root&password=taosdata";
Properties connProps = new Properties();
connProps.setProperty(TSDBDriver.PROPERTY_KEY_CHARSET, "UTF-8");
connProps.setProperty(TSDBDriver.PROPERTY_KEY_LOCALE, "en_US.UTF-8");
connProps.setProperty(TSDBDriver.PROPERTY_KEY_TIME_ZONE, "UTC-8");
Connection conn = DriverManager.getConnection(jdbcUrl, connProps);
return conn;
}
}
```
（3）测试jdbc访问tdengine的sever实例
console输出：
```
insert 2 rows.
2020-08-26 00:06:34.575, 23, 10.3
2020-08-26 00:06:35.575, 20, 9.3
```
## 指南
（1）如何设置主机名和hosts
在server上查看hostname和fqdn
```shell
查看hostname
# hostname
taos-server
查看fqdn
# hostname -f
taos-server
```
windows下hosts文件位于：
C:\\Windows\System32\drivers\etc\hosts
修改hosts文件，添加server的ip和hostname
```s
192.168.56.101 node5
```
（2）什么是fqdn？
> 什么是FQDN？
>
> FQDN（Full qualified domain name）全限定域名，fqdn由2部分组成：hostname+domainname。
>
> 例如，一个邮件服务器的fqdn可能是：mymail.somecollege.edu，其中mymail是hostname（主机名），somcollege.edu是domainname（域名）。本例中，.edu是顶级域名，.somecollege是二级域名。
>
> 当连接服务器时，必须指定fqdn，然后，dns服务器通过查看dns表，将hostname解析为相应的ip地址。如果只指定hostname（不指定domainname），应用程序可能服务解析主机名。因为如果你试图访问不在本地的远程服务器时，本地的dns服务器和可能没有远程服务器的hostname列表。

## TDengine Spring JDBC Template Demo
`Spring JDBC Template` 简化了原生 JDBC Connection 获取释放等操作，使得操作数据库更加方便。
### 配置
修改 `src/main/resources/applicationContext.xml` 文件中 TDengine 的配置信息：
```xml
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.taosdata.jdbc.TSDBDriver"></property>
<property name="url" value="jdbc:TAOS://127.0.0.1:6030/log"></property>
<property name="username" value="root"></property>
<property name="password" value="taosdata"></property>
</bean>
<bean id = "jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate" >
<property name="dataSource" ref = "dataSource" ></property>
</bean>
```
### 打包运行
进入 `TDengine/tests/examples/JDBC/SpringJdbcTemplate` 目录下，执行以下命令可以生成可执行 jar 包。
```shell
mvn clean package
```
打包成功之后，进入 `target/` 目录下，执行以下命令就可运行测试：
```shell

这个example中，我们适配了java常见的连接池:
* HikariCP（默认）
* druid
* dbcp
* c3p0
### 说明
ConnectionPoolDemo的程序逻辑：
1. 创建到host的connection连接池
2. 创建名称为pool_test的database，创建表超级weather，创建tableSize个子表
3. 总共插入totalNumber条数据。
### 如何运行这个例子：
```shell script
mvn clean package assembly:single
java -jar target/connectionPools-1.0-SNAPSHOT-jar-with-dependencies.jar -host 127.0.0.1
```
使用mvn运行ConnectionPoolDemo的main方法，可以指定参数
```shell script
Usage:
java -jar target/connectionPools-1.0-SNAPSHOT-jar-with-dependencies.jar
-host : hostname
-poolType <c3p0| dbcp| druid| hikari>
-poolSize <poolSize>
-tableSize <tableSize>
-batchSize : 每条Insert SQL中values的数量
-sleep : 每次插入任务提交后的
```
### 日志
使用log4j，将日志和错误分别输出到了debug.log和error.log中
