1、启动es：  
\[root@baozi elasticsearch-1.4.4\]\# bin/service/elasticsearch start  
Starting Elasticsearch...  
Waiting for Elasticsearch......  
running: PID:2409  
\[root@baozi elasticsearch-1.4.4\]\#  
  
  
2、向es里面创建一个索引库：  
\[root@baozi elasticsearch-1.4.4\]\# curl -XPUT 'http://localhost:9200/hello'  
\{"acknowledged":true\}\[root@baozi elasticsearch-1.4.4\]\#  
  
  
网页访问：http://192.168.1.200:9200/hello?pretty  
显示内容：  
\{  
  "hello" : \{  
    "aliases" : \{ \},  
    "mappings" : \{ \},  
    "settings" : \{  
      "index" : \{  
        "creation\_date" : "1435386285465",  
        "uuid" : "fbrLYbcmRfuRBYKlkcBvdw",  
        "number\_of\_replicas" : "1",  
        "number\_of\_shards" : "5",  
        "version" : \{  
          "created" : "1040499"  
        \}  
      \}  
    \},  
    "warmers" : \{ \}  
  \}  
\}  
  
  
3、向索引库hello里插入信息：  
\[root@baozi elasticsearch-1.4.4\]\# curl -XPUT 'http://localhost:9200/hello/emp/1' -d '\{"name":"zs","age":"23"\}'  
\{"\_index":"hello","\_type":"emp","\_id":"1","\_version":1,"created":true\}\[root@baozi elasticsearch-1.4.4\]\#  
  
  
网址：http://192.168.1.200:9200/hello?pretty  
显示信息：  
\{  
  "hello" : \{  
    "aliases" : \{ \},  
    "mappings" : \{  
      "emp" : \{  
        "properties" : \{  
          "age" : \{  
            "type" : "string"  
          \},  
          "name" : \{  
            "type" : "string"  
          \}  
        \}  
      \}  
    \},  
    "settings" : \{  
      "index" : \{  
        "creation\_date" : "1435386285465",  
        "uuid" : "fbrLYbcmRfuRBYKlkcBvdw",  
        "number\_of\_replicas" : "1",  
        "number\_of\_shards" : "5",  
        "version" : \{  
          "created" : "1040499"  
        \}  
      \}  
    \},  
    "warmers" : \{ \}  
  \}  
\}  
  
  
网址：http://192.168.1.200:9200/hello/emp/1?pretty  
  
  
显示内容：  
\{  
  "\_index" : "hello",  
  "\_type" : "emp",  
  "\_id" : "1",  
  "\_version" : 1,  
  "found" : true,  
  "\_source":\{"name":"zs","age":"23"\}  
\}  
  
  
  
es创建索引或者索引库的时候必须都用小写，不能以下划线开头，也不能包含逗号。  
  
  
PUT是幂等操作，必须加ID操作；用于更新  
POST不是幂等，ID加不加都可以；用于新增  
  
  
加ID了，PUT和POST都一样，不加ID不能用PUT。

GET操作：  
\[root@baozi elasticsearch-1.4.4\]\# curl -XGET http://192.168.1.200:9200/hello/emp/1?pretty  
\{  
  "\_index" : "hello",  
  "\_type" : "emp",  
  "\_id" : "1",  
  "\_version" : 1,  
  "found" : true,  
  "\_source":\{"name":"zs","age":"23"\}  
\}  
\[root@baozi elasticsearch-1.4.4\]\#  
  
  
  
反馈头文件：  
\[root@baozi elasticsearch-1.4.4\]\# curl -i http://192.168.1.200:9200/hello/emp/1?pretty

  "found" : true,  
  "\_source":\{"name":"zs","age":"23"\}  
\}  
\[root@baozi elasticsearch-1.4.4\]\#  
  
  
  
检索指定字段：  
\[root@baozi elasticsearch-1.4.4\]\# curl -XGET 'http://192.168.1.200:9200/hello/emp/1?\_source=name,age&pretty'  
\{  
  "\_index" : "hello",  
  "\_type" : "emp",  
  "\_id" : "1",  
  "\_version" : 1,  
  "found" : true,  
  "\_source":\{"age":"23","name":"zs"\}  
\}  
\[root@baozi elasticsearch-1.4.4\]\# curl -XGET 'http://192.168.1.200:9200/hello/emp/1?\_source=name&pretty'  
\{

  "\_type" : "emp",  
  "\_id" : "1",  
  "\_version" : 1,  
  "found" : true,  
  "\_source":\{"name":"zs"\}  
\}  
\[root@baozi elasticsearch-1.4.4\]\#  
  
  
  
只显示source：  
\[root@baozi elasticsearch-1.4.4\]\# curl -XGET 'http://192.168.1.200:9200/hello/emp/1/\_source'  
\{"name":"zs","age":"23"\}\[root@baozi elasticsearch-1.4.4\]\#  
  
  
关闭es：  
\[root@baozi elasticsearch-1.4.4\]\# bin/service/elasticsearch stop
