elasticsearch批量导入数据注意事项

刚刚初始化启动kiabna后是没有索引的，当然，如果elasticsearch中导入过数据那么kibana会自动匹配索引
现在按照官方例子开始批量给elasticsearch导入数据
链接如下https://www.elastic.co/guide/e ... .html
我们会依次导入如下 三块数据 
1.The Shakespeare data 莎士比亚文集的数据结构


{
    "line_id": INT,
    "play_name": "String",
    "speech_number": INT,
    "line_number": "String",
    "speaker": "String",
    "text_entry": "String",
}
2.The accounts data  账户数据结构


{
    "account_number": INT,
    "balance": INT,
    "firstname": "String",
    "lastname": "String",
    "age": INT,
    "gender": "M or F",
    "address": "String",
    "employer": "String",
    "email": "String",
    "city": "String",
    "state": "String"
}
3.The schema for the logs data 日志数据


{
    "memory": INT,
    "geo.coordinates": "geo_point"
    "@timestamp": "date"
}
然后向elasticsearch设置字段映射
Use the following command in a terminal (eg bash) to set up a mapping for the Shakespeare data set:
以下是莎士比亚的字段映射 可以用postman或者curl等发出请求~完整的url应该是localhost:9200/shakespear
PUT /shakespeare
{
 "mappings": {
  "doc": {
   "properties": {
    "speaker": {"type": "keyword"},
    "play_name": {"type": "keyword"},
    "line_id": {"type": "integer"},
    "speech_number": {"type": "integer"}
   }
  }
 }
}
Use the following commands to establish geo_point mapping for the logs:
这是 logs的字段映射
PUT /logstash-2015.05.18
{
  "mappings": {
    "log": {
      "properties": {
        "geo": {
          "properties": {
            "coordinates": {
              "type": "geo_point"
            }
          }
        }
      }
    }
  }
}
 
PUT /logstash-2015.05.19
{
  "mappings": {
    "log": {
      "properties": {
        "geo": {
          "properties": {
            "coordinates": {
              "type": "geo_point"
            }
          }
        }
      }
    }
  }
}
COPY AS CURLVIEW IN CONSOLE 
PUT /logstash-2015.05.20
{
  "mappings": {
    "log": {
      "properties": {
        "geo": {
          "properties": {
            "coordinates": {
              "type": "geo_point"
            }
          }
        }
      }
    }
  }
}
账户信息没有字段映射。。。
现在批量导入
curl -H 'Content-Type: application/x-ndjson' -XPOST 'localhost:9200/bank/account/_bulk?pretty' --data-binary @accounts.json
curl -H 'Content-Type: application/x-ndjson' -XPOST 'localhost:9200/shakespeare/doc/_bulk?pretty' --data-binary @shakespeare_6.0.json
curl -H 'Content-Type: application/x-ndjson' -XPOST 'localhost:9200/_bulk?pretty' --data-binary @logs.jsonl
windows下的curl命令可以到https://curl.haxx.se/download.html#Win64下载，解压后设置环境变量即可
这里要注意的是 @accounts.json，@shakespeare_6.0.json，@logs.json这些文件的位置应该是你所在的当前目录，
如果你当前位置是D盘~那么这些文件位置就要放在D盘下，否则读不到
还有一点~~~windows下要把命令行中的单引号换成双引号，，。。。否则会报
curl: (6) Could not resolve host: application这样的错误
