三级： 索引/类型/ID或操作符

对应： 数据库/表/ID

配置

启动服务： /es/elasticsearch -d 

添加认证： http://segmentfault.com/a/1190000002803609

用户名： admin , admin_pw

 

关闭： curl -XPOST http://localhost:9200/_cluster/nodes/_shutdown

关闭某一个索引： curl -XPOST http://localhost:9200/_cluster/nodes/[某一个索引]/_shutdown

查看索引： curl -XGet http://localhost:9200/_cluster/nodes

插件

Head

elasticsearch/bin/plugin -install mobz/elasticsearch-head

http://localhost:9200/_plugin/head/

 

Docker 安装 head

高版本的需要用新的方式安装 head

分词

IK官网：https://github.com/medcl/elasticsearch-analysis-ik

安装IK：bin/plugin -install medcl/elasticsearch-analysis-ik  

 

安装分词需要 Jdk7，Maven,Git，在最新的ES（1.7.1）上，网上的文章大部分都是错的。正确方法：

http://www.360doc.com/content/15/0114/13/16070877_440673208.shtml

如果这两篇文章存在有冲突的地方，使用后者。

步骤：

1.安装Jdk7，然后，再运行： set JAVA_HOME=C:\Program Files\Java\jdk1.7.0_80\bin

注意：安装的Jdk版本一定要和服务器使用的JRE版本一致。否则ES启动后，不可使用。

2.安装 Maven,Git

3.进入 D:\ik ，运行： clone https://github.com/medcl/elasticsearch-analysis-ik

4.进入 D:\ik\elasticsearch-analysis-ik

5.运行：mvn clean package

6.生成的 jar 在 D:\ik\elasticsearch-analysis-ik\target\releases\elasticsearch-analysis-ik-1.4.0.zip ， 其它的 jar 全是扯蛋。把它解出来。

附上链接： 百度网盘下载：elasticsearch-analysis-ik-1.4.0.zip

7. 把 解压缩的jar 拷贝到： ES_HOME/plugins/analysis-ik

8. 将下载目录中的ik目录拷贝到ES_HOME/config目录下面。

9.打开ES_HOME/config/elasticsearch.yml文件，在文件最后加入如下内容

index:
  analysis:                   
    analyzer:      
      ik:
          alias: [ik_analyzer]
          type: org.elasticsearch.index.analysis.IkAnalyzerProvider
      ik_max_word:
          type: ik
          use_smart: false
      ik_smart:
          type: ik
          use_smart: true

或：

index.analysis.analyzer.default.type: ik

10. 重新启动ES

11. 建一个索引，测试： 

 

curl -XPut 'http://localhost:9200/index/_analyze?analyzer=ik&pretty=true' -d '
{
"text":"世界如此之大"
}'

 

 

Maven

安装教程：http://jingyan.baidu.com/article/1709ad808ad49f4634c4f00d.html

官网：http://maven.apache.org/download.cgi

Git

过程

1. 创建索引：  Put ~/index

2. 获取所有Index： Get ~/_aliases

3. 创建别名： Put ~/<Index>/_alias/<Index_Alias>

4. 创建模板： Put  ~/<index>/_mapping/<type>  {type: {properties: { "列": { type:"string" }, "列2" : { type:  { Id: { type: "int"} , Name: { type: "string"} } } }}} 

对于《列2》来说，是一个对象类型，它可以是对象，也可以是对象数组。
