Centos7下使用ELK（Elasticsearch + Logstash + Kibana）搭建日誌集中分析平臺

Centos7下使用ELK（Elasticsearch + Logstash + Kibana）搭建日誌集中分析平臺
日誌監控和分析在保障業務穩定執行時，起到了很重要的作用，不過一般情況下日誌都分散在各個生產伺服器，且開發人員無法登陸生產伺服器，這時候就需要一個集中式的日誌收集裝置，對日誌中的關鍵字進行監控，觸發異常時進行報警，並且開發人員能夠檢視相關日誌。logstash+elasticsearch+kibana3就是實現這樣功能的一套系統，並且功能更強大。
Logstash：負責日誌的收集，處理和儲存
Elasticsearch：負責日誌檢索和分析
Kibana：負責日誌的視覺化

5、介面驗證
首先在client中手動增加一條日誌：
[[email protected] elk]# logger zhenyuLogtest
介面登入 http://192.168.7.27/ ，做如下操作
從圖中可以看到，手動新增的日誌已經在介面中被搜尋到了。
本文主要參考了國外一個搭建ELK的視訊，操作的很詳細，附上視訊的下載連結，僅供參考。
