logstash的安裝部署自行百度
注意：要和es的版本一致，這裡使用的都是5.5.1版本
一、在logstash的bin目錄下建立logstash.conf檔案：

input {
  file {
    path => ["C:\Users\Desktop\test.csv"]  
    start_position => "beginning"
  }
}
filter {
  csv {
    separator => ","
    columns => ["name","age"]
  }
  mutate {
    convert => {
      "name" => "string"
      "age" => "integer"
    }
  }
 }

output {
  elasticsearch {
        hosts => ["127.0.0.1:9200"]
        index => "test2"
		document_type => "test2"
  }
}
 

其中：

input

input元件負責讀取資料，使用以下外掛讀取不同的資料型別。
       file外掛讀取本地文字檔案，
       stdin外掛讀取標準輸入資料，
       tcp外掛讀取網路資料，
       log4j外掛讀取log4j傳送過來的資料等等。
path：csv檔案路徑
start_position：可以設定為beginning或者end，beginning表示從頭開始讀取檔案，end表示讀取最新的，這個也要和ignore_older一起使用。

filter

filter外掛負責過濾解析input讀取的資料
讀取csv檔案：
separator：拆分符
columns：csv檔案中的欄位，注意：要和 csv檔案中欄位順序一致

output

hosts：主機ip
index:設定es中的索引名稱
document_type：索引下的type名稱

對於csv檔案需要注意一下幾點：
1、第一行不需要儲存欄位名稱，直接就是欄位值資訊
2、最後一行要換行

二、在logstash的bin目錄下執行 logstash -f logstash.conf,出現如下資訊則表示執行成功：

注意：這個程序會一直處於執行狀態，若csv檔案被修改，程式會自動重新匯入資料；
若需要重新匯入資料，則需要刪除logstash安裝目錄下\data\plugins\inputs\file下的檔案。重新執行logstash -f logstash.conf

三、使用es-head檢視資料
