24-09-20 15:28:02 曹大卫 62

```shell
```bash
1、创建索引
curl -X PUT -u elastic:xxxx  "http://127.0.0.1:9200/索引名" -H 'Content-Type: application/json' -d'
{
  "settings": {
    "number_of_shards": 3,
    "number_of_replicas": 0
  }
}'

2、定义映射
curl -X PUT -u elastic:xxxx "http://127.0.0.1:9200/索引名/_mapping" -H 'Content-Type: application/json' -d'
{
  "properties": {
    "title": {
      "type": "text",
      "analyzer": "ik_max_word"
    },
    "content": {
      "type": "text",
      "analyzer": "ik_max_word"
    },
    "timestamp": {
      "type": "date"
    }
  }
}'

3、创建生命周期
curl -X PUT -u elastic:xxxx "http://127.0.0.1:9200/_ilm/policy/索引名_policy" -H 'Content-Type: application/json' -d'
{
  "policy": {
    "phases": {
      "hot": {
        "actions": {
          "rollover": {
            "max_age": "30d"
          }
        }
      },
      "warm": {
        "min_age": "30d",
        "actions": {
          "forcemerge": {
            "max_num_segments": 1
          },
          "shrink": {
            "number_of_shards": "3"
          },
          "allocate": {
            "require": {
              "node.attr.data_tier": "warm"
            }
          }
        }
      },
      "cold": {
        "min_age": "60d",
        "actions": {
          "allocate": {
            "require": {
              "node.attr.data_tier": "cold"
            }
          }
        }
      },
      "delete": {
        "min_age": "90d",
        "actions": {
          "delete": {}
        }
      }
    }
  }
}'

4、应用生命周期

curl -X POST -u elastic:xxxx "http://127.0.0.1:9200/index_template/索引名" -H 'Content-Type: application/json' -d'
{
  "index_patterns": ["索引名-*"],
  "template": {
    "settings": {
      "index.lifecycle.name": "索引名_policy",
      "index.lifecycle.rollover_alias": "索引名-*",
      "number_of_shards": 1,
      "number_of_replicas": 0
    }
  }
}'

5、查询索引及映射

curl -X GET -u elastic:xxxx "http://127.0.0.1:9200/索引名/_settings"
curl -X GET -u elastic:xxxx "http://127.0.0.1:9200/索引名/_mapping"
curl -X GET -u elastic:xxxx "http://127.0.0.1:9200/索引名"

###查询指定索引下的10个文档

curl -X GET -u elastic:xxxx "http://127.0.0.1:9200/索引名/_search?size=10000" -H 'Content-Type: application/json' -d'
{
  "query": {
    "match_all": {}
  }
}'

6、向索引插入一段文本
curl -X POST -u elastic:xxxx "http://127.0.0.1:9200/索引名/_doc" -H 'Content-Type: application/json' -d'
{
  "title": "测试索引",
  "content": "这是一段示例文本，插入数据。"
}'

7、搜索
curl -X GET -u elastic:xxxx "http://127.0.0.1:9200/索引名/_search" -H 'Content-Type: application/json' -d'
{
  "query": {
    "match": {
      "title":"登录"
    }
  }
}'

###增加文档字段
curl -X PUT elastic:xxxx "127.0.0.1:9200/索引名/_mapping" \
-H 'Content-Type: application/json' \
-d'
{
  "properties": {
    "author": {
      "": "text"
    }
  }
}'

8、根据文档id查询文档
curl -X GET -u elastic:xxxx "http://127.0.0.1:9200/索引名/_doc/MkC6jZEBc-nq0kMYYs4w"

9、根据文档id删除文档
curl -X DELETE -u elastic:xxxx "http://127.0.0.1:9200/索引名/_doc/TUABdJEBc-nq0kMYac2i?pretty"

```
