+	- IK 分词官网：<https://github.com/medcl/elasticsearch-analysis-ik>
+	- 官网首页已经有一个表格说明 ES 版本和 IK 插件的版本对应，我们可以看到：ES 2.4.1 对应 IK 分词 1.10.1，下载地址：<https://github.com/medcl/elasticsearch-analysis-ik/releases/tag/v1.10.1>
+	- 进入 ES 插件目录：`cd /usr/program/elk/elasticsearch-2.4.1/plugins`
+	- 创建 ik 目录：`mkdir ik`
+	- 把下载的 elasticsearch-analysis-ik-1.10.1.zip 上传到刚新建的 ik 目录下
+	- 解压：`unzip elasticsearch-analysis-ik-1.10.1.zip`
+	- 删除压缩包：`rm -rf elasticsearch-analysis-ik-1.10.1.zip`
+	- 编辑 ES 配置文件：`vim /usr/program/elk/elasticsearch-2.4.1/config/elasticsearch.yml`
+		- 在文件底部添加如下内容：
+
+``` ini
+index.analysis.analyzer.default.tokenizer : "ik_max_word"
+index.analysis.analyzer.default.type: "ik"
+```
+
+	- 重启 ES ： /usr/program/elk/elasticsearch-2.4.1/bin/elasticsearch
+	- 验证 ik 插件：浏览器访问：`http://192.168.1.127:9200/_analyze?analyzer=ik&pretty=true&text=这是一个针对程序员优化的导航GitNavi.com`，能得到如下结果就表示成功：
