4.ElasticSearch的基本api操作

1. ElasticSearch的Index

1. 索引初始化

在创建索引之前 对索引进行初始化操作
指定shards数量和replicas数量

curl -XPUT 'http://192.168.10.1:9200/library' -d {
    "settings":{
        "index":{
            "number_of_shards":5,
            "number_of_replicas":1,   
        }
    }
}

2. 查看索引信息

  1. GET 地址/索引名称/_settings 即可查看索引信息

    执行   
    curl -X GET http://192.168.10.1:9200/test/_settings 
    返回
    {
        "test": {
            "settings": {
                "index": {
                    "creation_date": "1507896234377",
                    "number_of_shards": "5",
                    "number_of_replicas": "1",
                    "uuid": "fhI9dJWsQoCswafewXNqrA",
                    "version": {
                        "created": "5010299"
                    },
                    "provided_name": "test"
                }
            }
        }
    }
    

3. 查看多个索引信息

  1. GET 地址/索引名称,索引名称/_settings 即可查看2个索引信息

    执行
    curl -X GET http://192.168.10.1:9200/test,test2/_settings
    返回
    {
        "test": {
            "settings": {
                "index": {
                    "creation_date": "1507896234377",
                    "number_of_shards": "5",

                    "provided_name": "test"
                }
            }
        }
        "test2": {
            "settings": {
                "index": {
                    "creation_date": "1506320574153",
                    "number_of_shards": "5",
                    "number_of_replicas": "1",
                    "uuid": "Ol-fhI9dJWsQoNqrA1jE1w",
                    "version": {

                }
            }
        }
    }
    

4. 查看所有索引信息

    执行
    curl -X GET 'http://192.168.10.1:9200/_cat/indices?v='
    返回
    省略了 因为太多了    
    

2. ElasticSearch的CURD

1. 创建索引

  1. 创建索引

    创建一个索引名称为test9的索引
    curl -X PUT http://192.168.10.1:9200/test9/ 
    返回
    {
    "acknowledged": true,
    "shards_acknowledged": true
    }
    
  2. 创建索引及类型和文档

    PUT 地址/索引名称/type名称/文档id
    执行
    curl -X PUT http://192.168.10.1:9200/test10/people/1 -d 
    '{
    	"title": "test10"
    }' 
    返回
    {
