elastic 基本操作

官方参考文档：

1、查看 有哪些索引：

 

 curl 'localhost:9200/_cat/indices?v'
 

 

1.1查看索引结构：

 

GET /索引名/_mapping?pretty

创建索引：
PUT 索引名
  比如：

put  admin_index
{
    "settings": {
        "number_of_shards": 6,
        "number_of_replicas": 1
    },
    "mappings": {
        "logs": {
            "properties": {
                "esCreateTime": {
                    "type": "long"
                },
                "id": {
                    "type": "long"
                },
                "ip": {
                    "type": "text",
                    "fields": {
                        "keyword": {
                            "type": "keyword",
                            "ignore_above": 256
                        }
                    }
                },
                "uri": {
                    "type": "text",
                    "fields": {
                        "keyword": {
                            "type": "keyword",
                            "ignore_above": 256
                        }
                    }
                },
                "userId": {
                    "type": "text",
                    "fields": {
                        "keyword": {
                            "type": "keyword",
                            "ignore_above": 256
                        }
                    }
                },
                "userName": {
                    "type": "text",
                    "fields": {
                        "keyword": {
                            "type": "keyword",
                            "ignore_above": 256
                        }
                    }
                }
            }
        }
    }
}

 

2、添加索引：

 

 curl -XPUT 'localhost:9200/customer?pretty'
 curl 'localhost:9200/_cat/indices?v'

3、删除索引

  

 curl -XDELETE 'localhost:9200/customer?pretty'
 curl 'localhost:9200/_cat/indices?v'

4、更新数据

 

   

curl -XPOST 'localhost:9200/_index/_type/_id/_update?pretty' -d '

curl -XPOST 'localhost:9200/customer/external/1/_update?pretty' -d '
{
  "doc": { "name": "Jane Doe", "age": 20 }
}

查看原来的数据

curl -XPOST 'localhost:9200/customer/external/_bulk?pretty' -d '

　　{"index":{"_id":"1"}}

　　{"name": "John Doe" }

　　{"index":{"_id":"2"}}

　　{"name": "Jane Doe" }

http://localhost:9200/indexName/typeName/_update_by_query

　　{ "script": {"source":"ctx._source['user_name']='LsiuLi';ctx._source['assignedto_id']='123';"}, "query": {"term": {"user_id": 60} }

　批量处理：

　下面语句批处理执行更新id为1的数据然后执行删除id为2的数据

　　curl -XPOST 'localhost:9200/customer/external/_bulk?pretty' -d '

　　{"update":{"_id":"1"}}

　　{"doc": { "name": "John Doe becomes Jane Doe" } }

　　{"delete":{"_id":"2"}}

　　'
