01架构说明
在需要采集日志的服务器上部署Filebeat服务，它将采集到的日志数据推送到Kafka集群；Logstash服务通过input插件读取Kafka集群对应主题的数据，期间可以使用filter插数据做自定义过滤解析处理，然后通过output插件将数据推送到Elasticsearch集群中；最后用户通过Kibana服务提供的web界面，对索引数据做汇总，分析，搜索和展示等功能
本文旨在部署安全可靠的生产架构，对ELK做XPack安全加固，对Kafka做SASL安全加固！
02准备工作
本文的ELK全家桶版本为7.2.0，Kafka版本为2.12-2.3.0。
03环境配置
主要的操作有：关闭selinux安全机制，关闭firewalld防火墙，关闭swap交换内存空间，文件及内存限制配置，设置jvm参数，创建普通用户，准备磁盘存储目录等；建议做好服务器间的免密登陆操作。

04Elasticsearch集群部署
Elasticsearch 是一个分布式、RESTful风格的搜索和数据分析引擎；它实现了用于全文检索的倒排索引，而且为每个数据都编入了索引，搜索速度非常快；它具有可扩展性和弹性，每秒钟能处理海量事件，并且它适用于所有数据类型，例如结构化数据、非结构化数据、地理位置等。
笔者在生产环境上，为Elasticsearch分配了30G内存（最大不要超过32G），6块446G的SSD磁盘，并使用G1的垃圾回收策略，关于硬件配置大家根据实际情况来分配使用！
提示：笔者已事先下载好了所有软件包到服务器上；本文的三个es节点默认都做主节点和数据节点，当使用xpack加密时，主节点也必须做数据节点，否则加密配置写入不进es存储！
在本文中，笔者直接在83节点上完成了es集群的部署，请仔细阅读下方的命令！

05Kafka集群部署
Kafka 是最初由Linkedin公司开发，是一个分布式、分区的、多副本的、多订阅者，基于zookeeper协调的分布式消息系统；它具有高吞吐量、低延迟、可扩展性、持久性、可靠性、容错性和高并发等特点，可以处理几十万条消息，延迟只有几毫秒，集群式部署支持热扩展，消息可被持久化到本地磁盘，防止数据丢失，而且支持数千个客户端同时读写。
在本文的架构中，kafka是用作缓存消息队列，用来实时接收日志和发送日志到logstash，实现解耦和流量削峰，解决logstash消费能力跟不上导致的数据丢失问题；笔者采用的是kafka内置的zookeeper，也是以集群方式部署，无需再单独搭建zookeeper集群服务。
注意：kafka的集群配置信息，状态维护是存储在zookeeper这个进程里的，所以kafka在启动前需要先配置启动zookeeper！
笔者为zookeeper服务分配了4G内存，为kafka服务分配了31G内存和5块SSD磁盘，关于硬件配置大家根据实际情况来分配使用！

当zk和kafka服务都启动后，可以先检查下相关端口状态是否正常
[root@es83 kafka_2.12-2.3.0]# netstat -antlp | grep -E "2888|3888|2181|9092"
当集群服务一切正常后，即可在其中一台kafka节点上配置ACL访问控制权限，对生产者producer和消费者consumer的主题topic和组group设置访问权限，可以限制只允许指定的机器访问。
提示：下面的mykafka是通过/etc/hosts自定义一个IP的域名，例如：192.168.100.83 mykafka；如果写成localhost可能没有权限，执行命令后会报NoAuth；如果写成IP地址会报CONNECT !!!

06Logstash服务部署
Logstash 是免费且开放的服务器端数据处理管道，采用的是可插拔框架，拥有200多个插件，支持各种输入和输出选择，能够实时解析和转换数据，具有可伸缩性、弹性和灵活性；但是它比较消耗资源，运行时占用较高的CPU和内存，如果缺少消息队列缓存，会有数据丢失的隐患，所以小伙伴们要结合自身情况来使用！
笔者在生产环境上，也为Logstash分配了30G内存，关于硬件配置大家根据实际情况来分配使用！

07Kibana服务部署
Kibana 是一个开源的分析和可视化平台，可以为Logstash和ElasticSearch提供的日志数据进行高效的搜索、可视化汇总和多维度分析，并且与Elasticsearch索引中的数据进行交互；它基于浏览器的界面操作可以快速创建动态仪表板，实时监控ElasticSearch的数据状态与更改等。
笔者在生产环境上，为Kibana分配了8G内存，关于硬件配置大家根据实际情况来分配使用！

完成以上操作后，可使用浏览器访问kibana地址https://192.168.100.83，输入elastic用户密码即可！

08Filebeat服务部署
Filebeat 是一个用于转发和集中日志数据的轻量级采集器，基于go语言开发，性能稳定，配置简单，占用资源很少；它作为agent安装在服务器上，可以监控你指定的日志文件或位置，收集日志事件，并将其转发到配置的输出；主要通过探测器prospector和收集器harvester组件完成工作。
