因为装的JDK 是1.7. elasticsearch 版本0.9，1.3-2.4 ，1.3支持JDK1.7，1.3以上的都支持1.8了。所以下载安装的是es 1.3版本；
下载 curl -L -O https://download.elastic.co/elasticsearch/elasticsearch/elasticsearch-1.3.9.tar.gz
解压 tar -xvf elasticsearch-1.3.9.tar.gz
启动 cd elasticsearch-1.3.9/bin ./elasticsearch
官网原话：
If everything goes well, you should see a bunch of messages that look like below:
./elasticsearch

1. elasticsearch 作为一个系统service应用 ，可以安装elasticsearch-servicewrapper插件。
在https://github.com/elasticsearch/elasticsearch-servicewrapper下载该插件后，解压缩。将service目录拷贝到elasticsearch目录的bin目录下。运行这个插件的好处是：elasticsearch需要的jvm参数和其它配置都已经配置好了，非常方便。
安装完启动 cd bin/service sh elasticsearch start 即可 属于 后台启动。 官网命令如下：
| Parameter | Description |
|---|---|
| console | Run the elasticsearch in the foreground. |
| start | Run elasticsearch in the background. |
| stop | Stops elasticsearch if its running. |
| install | Install elasticsearch to run on system startup (init.d / service). |
| remove | Removes elasticsearch from system startup (init.d / service). |
2. 安装es-head插件
进入elasticsearch/bin目录，输入命令./plugin –install mobz/elasticsearch-head 安装head插件。 安装成功以后 在浏览器中输入http://localhost:9200，http://localhost:9200/_plugin/head/如下图所示则ES启动成功。
