01架構說明

在需要采集日志的服務器上部署Filebeat服務，它將采集到的日志數據推送到Kafka集群；
Logstash服務通過input插件讀取Kafka集群對應主題的數據，期間可以使用filter插
數據做自定義過濾解析處理，然后通過output插件將數據推送到Elasticsearch集群中；
最后用戶通過Kibana服務提供的web界面，對索引數據做匯總，分析，搜索和展示等功能

本文旨在部署安全可靠的生產架構，對ELK做XPack安全加固，對Kafka做SASL安全加固！

02準備工作

在這里插入圖片描述
本文的ELK全家桶版本為7.2.0，Kafka版本為2.12-2.3.0。

03環境配置

主要的操作有：關閉selinux安全機制，關閉firewalld防火墻，關閉swap交換內存空間，文件及內存限制配置，設置jvm參數，創建普通用戶，準備磁盤存儲目錄等；建議做好服務器間的免密登陸操作。

04Elasticsearch集群部署

Elasticsearch 是一個分布式、RESTful風格的搜索和數據分析引擎；它實現了用于全文檢索的倒排索引，而且為每個數據都編入了索引，搜索速度非常快；它具有可擴展性和彈性，每秒鐘能處理海量事件，并且它適用于所有數據類型，例如結構化數據、非結構化數據、地理位置等。

筆者在生產環境上，為Elasticsearch分配了30G內存（最大不要超過32G），6塊446G的SSD磁盤，并使用G1的垃圾回收策略，關于硬件配置大家根據實際情況來分配使用！

filebeat啟動命令？提示：筆者已事先下載好了所有軟件包到服務器上；本文的三個es節點默認都做主節點和數據節點，當使用xpack加密時，主節點也必須做數據節點，否則加密配置寫入不進es存儲！

在本文中，筆者直接在83節點上完成了es集群的部署，請仔細閱讀下方的命令！

05Kafka集群部署

Kafka 是最初由Linkedin公司開發，是一個分布式、分區的、多副本的、多訂閱者，基于zookeeper協調的分布式消息系統；它具有高吞吐量、低延遲、可擴展性、持久性、可靠性、容錯性和高并發等特點，可以處理幾十萬條消息，延遲只有幾毫秒，集群式部署支持熱擴展，消息可被持久化到本地磁盤，防止數據丟失，而且支持數千個客戶端同時讀寫。

filebeat、在本文的架構中，kafka是用作緩存消息隊列，用來實時接收日志和發送日志到logstash，實現解耦和流量削峰，解決logstash消費能力跟不上導致的數據丟失問題；筆者采用的是kafka內置的zookeeper，也是以集群方式部署，無需再單獨搭建zookeeper集群服務。
注意：kafka的集群配置信息，狀態維護是存儲在zookeeper這個進程里的，所以kafka在啟動前需要先配置啟動zookeeper！

筆者為zookeeper服務分配了4G內存，為kafka服務分配了31G內存和5塊SSD磁盤，關于硬件配置大家根據實際情況來分配使用！

當zk和kafka服務都啟動后，可以先檢查下相關端口狀態是否正常

[root@es83 kafka_2.12-2.3.0]# netstat -antlp | grep -E "2888|3888|2181|9092"

filebeat不讀取文件。當集群服務一切正常后，即可在其中一臺kafka節點上配置ACL訪問控制權限，對生產者producer和消費者consumer的主題topic和組group設置訪問權限，可以限制只允許指定的機器訪問。

提示：下面的mykafka是通過/etc/hosts自定義一個IP的域名，例如：192.168.100.83 mykafka；如果寫成localhost可能沒有權限，執行命令后會報NoAuth；如果寫成IP地址會報CONNECT !!!

06Logstash服務部署

Logstash 是免費且開放的服務器端數據處理管道，采用的是可插拔框架，擁有200多個插件，支持各種輸入和輸出選擇，能夠實時解析和轉換數據，具有可伸縮性、彈性和靈活性；但是它比較消耗資源，運行時占用較高的CPU和內存，如果缺少消息隊列緩存，會有數據丟失的隱患，所以小伙伴們要結合自身情況來使用！

kafka部署？筆者在生產環境上，也為Logstash分配了30G內存，關于硬件配置大家根據實際情況來分配使用！

07Kibana服務部署

Kibana 是一個開源的分析和可視化平臺，可以為Logstash和ElasticSearch提供的日志數據進行高效的搜索、可視化匯總和多維度分析，并且與Elasticsearch索引中的數據進行交互；它基于瀏覽器的界面操作可以快速創建動態儀表板，實時監控ElasticSearch的數據狀態與更改等。

筆者在生產環境上，為Kibana分配了8G內存，關于硬件配置大家根據實際情況來分配使用！

08Filebeat服務部署

Filebeat 是一個用于轉發和集中日志數據的輕量級采集器，基于go語言開發，性能穩定，配置簡單，占用資源很少；它作為agent安裝在服務器上，可以監控你指定的日志文件或位置，收集日志事件，并將其轉發到配置的輸出；主要通過探測器prospector和收集器harvester組件完成工作。
