ELK自動安裝腳本
一、簡介
ELK由Elasticsearch、Logstash和Kibana三部分組件組成；
Elasticsearch是個開源分佈式搜索引擎，它的特點有：分佈式，零配置，自動發現，索引自動分片，索引副本機制，restful風格接口，多數據源，自動搜索負載等。
Logstash是一個完全開源的工具，它可以對你的日誌進行收集、分析，並將其存儲供以後使用
kibana 是一個開源和免費的工具，它可以爲 Logstash 和 ElasticSearch 提供的日誌分析友好的 Web 界面，可以幫助您彙總、分析和搜索重要數據日誌。
二、核心組件
Logstash: logstash server端用來蒐集日誌；
Elasticsearch: 存儲各類日誌；
Kibana: web化接口用作查尋和可視化日誌；
Filebeat是一個日誌文件託運工具，在你的服務器上安裝客戶端後，filebeat會監控日誌目錄或者指定的日誌文件，追蹤讀取這些文件（追蹤文件的變化，不停的讀），並且轉發這些信息到elasticsearch或者logstarsh中存放。
三、安裝腳本
注意：vim /etc/hosts 添加ip及主機名； 注意：服務器的內存如果服務器內存低的話會導致elasticsearch啓動不了；
自定義shell腳本名稱 vim Autoinstall_ELK_V1.3.sh 複製粘貼一下內容執行。
