curl操作elasticsearch常用命令

说明：这些命令针对es7.x，6 以下版本可能无效，elastic 6 / 7不同版本命令差别较大。。

创建索引

这里创建索引名为fc_search，type和data是关键字类型，也就是不进行分词，keyword_1是text类型，默认分词，并且指定分词方式为ik_smart。

curl -u elastic:changeme -X PUT  http://192.168.20.130:9200/fc_search -H 'Content-Type: application/json' -d'
{
  "settings" : {
      "number_of_shards" : 1,
      "number_of_replicas" : 1
   },
    "mappings" : {
        "properties": {
          "id": {
            "type" : "long"
          }, 
          "type": {
            "type": "long"
          }, 
          "keyword_1": {
            "type": "text",
            "analyzer" : "ik_max_word"
          }, 
          "keyword_2": {
            "type": "text",
            "analyzer" : "ik_max_word"
          },
          "keyword_3": {
            "type": "text",
            "analyzer" : "ik_max_word"
          },
          "data": {
            "type": "keyword"
          },
          "created_at": {
            "type": "date",
            "format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd"
          }, 
          "updated_at": {
            "type": "date",
            "format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd"
          }
      }
    }
}'

添加文档

curl -u elastic:changeme -X POST  http://192.168.20.130:9200/fc_search/_doc/1 -H 'Content-Type: application/json' -d'
{
  "id": 10000,
  "data": "data",
  "keyword_1": "蓝色渐变时尚家居通用PPT模板,弧形,家居,地板,装修,蓝色,曲线,通用,家居,时尚,其他"
}'

说明：http://192.168.20.130:9200/fc_search/_doc/1?pretty，这里的_doc表示类型，1表示doc_id 。

查询

查询所有

curl -u elastic:changeme -X GET  http://192.168.20.130:9200/fc_search/_search

结果:

{"_index":"fc_search","_type":"_doc","_id":"5_1","_version":1,"_seq_no":5,"_primary_term":1,"found":true,"_source":{"id":1,"type":5,"keyword_1":"测试1","keyword_2":"测试2","keyword_3":"测试3"}}

根据文档id查询

curl -u elastic:changeme -X GET  http://192.168.20.130:9200/fc_search/_doc/5_1

结果不美观，es里面查询如果想让json结果规整，可以末尾加?pretty

curl -u elastic:changeme -X GET  http://192.168.20.130:9200/fc_search/_doc/5_1?pretty

结果：

{
"_index" : "fc_search",
"_type" : "_doc",
"_id" : "5_1",
"_version" : 1,
"_seq_no" : 5,
"_primary_term" : 1,
"found" : true,
"_source" : {
"id" : 1,
"type" : 5,
"keyword_1" : "测试1",
"keyword_2" : "测试2",
"keyword_3" : "测试3"
}
}

根据关键字查询(模糊匹配)

curl -u elastic:changeme -X POST  http://192.168.20.130:9200/fc_search/_search?pretty -H 'Content-Type: application/json' -d'
{
"query": {
    "match": {
        "keyword_1.keyword": "蓝色,简约"
    }
}
}'

这种方式查询，是模糊匹配，忽略分词。

根据分词查询

curl -u elastic:changeme -X POST  http://192.168.20.130:9200/fc_search/_search?pretty -H 'Content-Type: application/json' -d'
{
"from": 0,
"size": 20,
"query": {
    "bool": {
        "should": [{
                "match": {
                    "keyword_1": "蓝色,简约"
                }
            }
        ]
    }
}
}'

keyword_1是被分词了的，这种方式是按照分词匹配，搜索关键词也会被分词为：

修改索引（给字段添加分词属性）

创建索引fc_search_copy

curl -u elastic:changeme -X PUT  http://192.168.20.130:9200/fc_search_copy -H 'Content-Type: application/json' -d'
{
  "settings" : {
      "number_of_shards" : 1,
      "number_of_replicas" : 1
   },
    "mappings" : {
        "properties": {
          "id": {
            "type" : "long"
          }, 
          "type": {
            "type": "long"
          }, 
          "keyword_1": {
            "type": "text",
            "analyzer" : "ik_max_word"
          }, 
          "keyword_2": {
            "type": "text",
            "analyzer" : "ik_max_word"
          },
          "keyword_3": {
            "type": "text",
            "analyzer" : "ik_max_word"
          },
          "data": {
            "type": "keyword"
          },
          "created_at": {
            "type": "date",
            "format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd"
          }, 
          "updated_at": {
            "type": "date",
            "format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd"
          }
      }
    }
}'

查看新建立的索引

curl -u elastic:changeme -X GET  http://192.168.20.130:9200/fc_search_copy/_mapping

同步数据到新的索引

curl -u elastic:changeme -X POST  http://192.168.20.130:9200/_reindex -H 'Content-Type: application/json' -d'
{
  "source": {
    "index": "fc_search"
  },
  "dest": {
    "index": "fc_search_copy"
  }
}'

删除旧的索引

curl -u elastic:changeme -X DELETE  http://192.168.20.130:9200/fc_search

新的索引添加别名

curl -u elastic:changeme -X POST http://192.168.20.130:9200/_aliases -H 'Content-Type: application/json' -d'
{
  "actions": [
    {
      "add": {
        "index": "fc_search_copy",
        "alias": "fc_search"
      }
    }
  ]
}'

思路是将旧索引数据复制一份到新的索引，然后删除旧索引，最后将新索引添加别名，别名就是旧索引的名字，这样不会影响原来的代码。

常用命令

获取es集群信息，包括版本和集群名称等。

curl -u elastic:changeme -X GET  http://192.168.20.130:9200

获取到的信息如下：

{
"name" : "1653018488005162032",
"cluster_name" : "es-lp827qju",
"cluster_uuid" : "UuxuP35SQjqInlTs0cNDkA",
"version" : {
"number" : "7.14.2",
"build_flavor" : "default",
"build_type" : "tar",
"build_hash" : "da023f0226db21490ed0b4bb422b13d8f1926863",
"build_date" : "2022-04-14T08:25:18.177087482Z",
"build_snapshot" : false,
"lucene_version" : "8.9.0",
"minimum_wire_compatibility_version" : "6.8.0",
"minimum_index_compatibility_version" : "6.0.0-beta1"
},
"tagline" : "You Know, for Search"
}

查看索引mapping即字段属性信息：

http://192.168.20.130:9200/fc_search_test/_mapping

结果：

{
    "fc_search_test": {
        "mappings": {
            "properties": {
                "created_at": {
                    "type": "date",
                    "format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd"
                },
                "data": {
                    "type": "keyword"
                },
                "id": {
                    "type": "long"
                },
                "keyword_1": {
                    "type": "text",
                    "analyzer": "ik_max_word"
                },
                "keyword_2": {
                    "type": "text",
                    "analyzer": "ik_max_word"
                },
                "keyword_3": {
                    "type": "text",
                    "analyzer": "ik_max_word"
                },
                "type": {
                    "type": "long"
                },
                "updated_at": {
                    "type": "date",
                    "format": "yyyy-MM-dd HH:mm:ss||yyyy-MM-dd"
                }
            }
        }
    }
}

查询全部数据

http://192.168.20.130:9200/fc_search_test/_search

清空索引数据

curl -u elastic:changeme -X POST http://192.168.20.130:9200/ppt_content/_delete_by_query -H 'Content-Type: application/json' -d'
{
"actions": [
{
  "query": {
        "match_all": {}
      }
}
]
}'

根据文档id查询数据

curl -u elastic:changeme -X GET  http://192.168.20.130:9200/fc_search/_doc/5_5?pretty

给索引添加别名

curl -u elastic:changeme -X POST http://192.168.20.130:9200/_aliases -H 'Content-Type: application/json' -d'
{
"actions": [
{
  "add": {
    "index": "fc_search_copy",
    "alias": "fc_search"
  }
}
]
}'

查询时候，索引名跟索引别名效果是一样的。

删除索引

curl -u elastic:changeme -X DELETE  http://192.168.20.130:9200/fc_search_test
