# 安装Elasticsearch （v6.1.3）
下载地址 https://www.elastic.co/downloads/elasticsearch

# 运行Elasticsearch
```
./bin/elasticsearch
```
如果想在后台以守护进程模式运行，添加-d参数。
```
./bin/elasticsearch -d
```

# 使用RESTful API

在elasticsearch.yml中添加以下内容，开启跨域支持：
```
#开启跨域访问支持，默认为false    
http.cors.enabled: true  

#跨域访问允许的域名地址，(允许所有域名)以上使用正则  
http.cors.allow-origin: /.*/  
```

```

# 计算集群中的文档数量

    }
}

    "successful": 0,
    "skipped": 0,
    "failed": 0
  }
}
```

# 添加一个文档
```
PUT http://localhost:9200/megacorp/employee/1

// megacorp 索引
// employee 类型
// 1 id

// Body

{
    "first_name" : "John",
    "last_name" :  "Smith",
    "age" :        25,
    "about" :      "I love to go rock climbing",
    "interests": [ "sports", "music" ]
}
```

Response:

```
{
  "_index": "megacorp",
  "_type": "employee",
  "_id": "1",
  "_version": 1,
  "result": "created",
  "_shards": {
    "total": 2,
    "successful": 1,
    "failed": 0
  },
  "_seq_no": 0,
  "_primary_term": 1
}
```

在Elasticsearch中，文档归属于一种类型(type),而这些类型存在于索引(index)中，我们可以画一些简单的对比图来类比传统关系型数据库：
```
Relational DB -> Databases -> Tables -> Rows -> Columns
Elasticsearch -> Indices   -> Types  -> Documents -> Fields
```
