系统：ubuntu 16.04
IDE：IDEA 2016.3
Apache Ignite 版本： 1.8.0
Java 版本 1.8.0_101

下载并安装ignite

去官网下载最新版即可

设置环境变量

将下载下来的压缩包解压，然后

export IGNITE_HOME=/home/abc/ignite1.8

等号后面是解压的目录，目录下有bin，examples等目录

启动ignite集群（cluster）

进入刚才解压的目录，使用命令+配置文件的方法启动ignite，多开两个终端，然后多开两个ignite。
命令如下：

$ bin/ignite.sh examples/config/example-ignite.xml

添加依赖项目

上面是系统里面的操作，下面要打开idea这个IDE进行操作。
首先新建一个maven项目，添加依赖到pom.xml文件中<dependencies>这个选项。
整个pom.xml文件如下：

<?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>igniteHelloWorld</groupId>
    <artifactId>igniteHelloWorld</artifactId>
    <version>1.0-SNAPSHOT</version>
    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                </configuration>
            </plugin>
        </plugins>
    </build>

    <dependencies>
        <dependency>
            <groupId>org.apache.ignite</groupId>
            <artifactId>ignite-core</artifactId>
            <version>1.8.0</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/org.apache.ignite/ignite-spring -->
        <dependency>
            <groupId>org.apache.ignite</groupId>
            <artifactId>ignite-spring</artifactId>
            <version>1.8.0</version>
        </dependency>

        <dependency>
            <groupId>com.h2database</groupId>
            <artifactId>h2</artifactId>
            <version>1.3.175</version>
        </dependency>
    </dependencies>
</project>

这边依赖项一开始的时候我没有加入h2database，然后ignite就无法启动，只好把他加上。

helloworld.java

import org.apache.ignite.Ignite;
import org.apache.ignite.IgniteCache;
import org.apache.ignite.IgniteException;
import org.apache.ignite.Ignition;

public class HelloWorld {
  public static void main(String[] args) throws IgniteException {
    try (Ignite ignite = Ignition.start("examples/config/example-ignite.xml")) {
      // Put values in cache.
      IgniteCache<Integer, String> cache = ignite.getOrCreateCache("myCache");

      cache.put(1, "Hello");
      cache.put(2, "World!");

      // Get values from cache and
      // broadcast 'Hello World' on all the nodes in the cluster.
      ignite.compute().broadcast(() -> {
        String hello = cache.get(1);
        String world = cache.get(2);

        System.out.println(hello + " " + world);
      });
    }
  }
}

设置java虚拟机选项

在Run –> Edit Configurations –> VM options (在Configuration页面) 输入:

-DIGNITE_HOME=ignite安装路径

查看输出结果
