一、添加索引

创建索引

curl -X PUT "localhost:9200/my-index-00001?pretty"

获取索引

curl -X GET "localhost:9200/my-index-000001?pretty"

获取全部的索引

curl -X GET "http://localhost:9200/_cat/indices?v"

获取索引映射

curl -X GET "localhost:9200/my-index-000001/_mapping?pretty"

删除索引

curl -X DELETE "localhost:9200/my-index-000001?pretty"

添加映射：

浏览器里执行

PUT /my-index-000001/_mapping
{
  "properties": {
     "ip": {
          "type": "text",
          "fields": {
            "keyword": {
              "type": "keyword",
              "ignore_above": 256
            }
          }
        }
  }
}

命令行执行

curl -XPUT "http://localhost:9200/my-index-000001/_mapping" -H 'Content-Type: application/json' -d'{  "properties": {     "ip": {          "type": "text",          "fields": {            "keyword": {              "type": "keyword",              "ignore_above": 256            }          }        }  }}'

重启客户端（这里用的是canal客户端，同步的mysql数据库）

导入数据

curl -X POST  http://127.0.0.1:8081/etl/es7/mytest_user.yml

这是我的安装目录：

配置： /www/canal/adapter/conf/es7/mytest_user.yml

dataSourceKey: defaultDS
destination: example
groupId: g1
esMapping:
  _index: my-index-000001
  _id: _id
#  upsert: true
#  pk: id
  sql: "select a.id as _id,a.id from t_data_order202306 a"
#  objFields:
#    _labels: array:;
  etlCondition: "where a.id>={}"
  commitBatch: 3000

查询数据

浏览器查询：

GET /my-index-000001/_search
{
  "query": {
    "match": {
      "id": "0000391d-7907-4491-907f-9ebe9d71ab3f"
    }
  }
}

命令行查询：

curl -XGET "http://localhost:9200/my-index-000001/_search" -H 'Content-Type: application/json' -d'{  "query": {    "match": {      "id": "0000391d-7907-4491-907f-9ebe9d71ab3f"    }  }}'
