環境要求：

# CentOS7
# Javaa 1.8

IP	hostname	軟體	記憶體要求
192.168.122.3	elk-1	Elasticsearch、Logstash	2G及以上
192.168.122.4	Kibana	Kibana	1G及以上
192.168.122.5	Filebeat	Filebeat	1G及以上

注意事項

# 1.一定要對時，時間校正，不然日誌出不來；
# 2.java包最好用openjdk；
# 3.啟動Elasticsearch必須切換成所建立的ELK使用者啟動，不然ES出於安全目的，會啟動報錯；
# 4.日誌從Filebeat到Logstash再到ES檢索到Kibana的讀取速度取決於機器配置，注意用
# cat  日誌檔案*  |  wc  -l   統計日誌數量，然後到Elasticsearch去看總數量，確保日誌都過來了在進行分析；

Elasticsearch安裝

初始化

curl -o /etc/yum.repos.d/163.repo http://mirrors.163.com/.help/CentOS7-Base-163.repo &>/dev/null
curl  -o /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo 
	yum -y install ntpdate
	ntpdate -b  ntp1.aliyun.com

設定Hostname解析

		hostnamectl set-hostname elk-1
		## 修改/etc/hosts 增加如下內容
		192.168.122.3     elk-1

java安裝

		# 安裝java 1.8
		yum -y install java-1.8.0-openjdk.x86_64

關閉防火牆，SeLinux

		setenforce 0
		sed -i '/^SELINUX=/ s/enforcing/disabled/'  /etc/selinux/config
		systemctl stop firewalld
		systemctl disable firewalld
		sed -i '/^GSSAPIAu/ s/yes/no/' /etc/ssh/sshd_config
		sed -i '/^#UseDNS/ {s/^#//;s/yes/no/}' /etc/ssh/sshd_config

建立使用者和組

		# create  user elk
		groupadd  elk
		useradd  elk  -g  elk

建立資料及日誌檔案並授權

		mkdir  -pv  /data/elk/{data,logs}
		chown  -R  elk:elk  /data/elk/

軟體包解壓、授權

# 上傳軟體包
#	通過scp 或者FTP方式上傳到/opt下
# 解壓軟體包到/opt目錄
		tar xvf elasticsearch-7.2.0-linux-x86_64.tar.gz -C  /opt/
# 授權
		chown  -R  elk:elk  # 軟體包名

elk-1配置檔案

		# 叢集名
		cluster.name:  elk
		# 節點名
		node.name: node-1
		# 儲存資料
		path.data:  /data/elk/data
		# 存放日誌
		path.logs:  /data/elk/logs
		# 鎖記憶體，儘量不使用交換記憶體
		bootstrap.memory_locak:  false
		# 網路地址
		network.host: 0.0.0.0
		http.port: 9200
		# 發現叢集hosts
		discovery.sead_hosts: ["elk-1"]
		# 設定叢集master節點
		cluster.inital_master_nodes: ["node-1"]

修改/etc/security/limits.conf

		# *號不是註釋
		* soft nofile 65536
		* hard nofile 131072
		* soft nproc 2048
		* hard nproc 4096

修改/etc/sysctl.conf

		echo "vm.max_map_count=262144" >> /etc/sysctl.conf
		sysctl -p

ES啟動

		nohup runuser -l elk -c '/bin/bash /opt/elasticsearch-7.2.0/bin/elasticsearch' &

檢查叢集健康狀態

		curl -XGET 'elk-1:9200/_cluster/health?pretty'

Kibana安裝使用

解壓Kibana安裝包

		tar xvf kibana-7.2.0-linux-x86_64.tar.gz  -C /opt/

修改Kibana配置檔案

		vim /opt/kibana-7.2.0-linux-x86_64/config/kibana.yml
			server.port:  5601   # Port
			server.host:  0.0.0.0   # 訪問限制
			elasticsearch.hosts: ["http://ESHostIP:9200"]

啟動命令

		/opt/kibana-7.2.0-linux-x86_64/bin/kibana --allow-root
		nohup  /opt/kibana-7.2.0-linux-x86_64/bin/kibana --allow-root  &  放入後臺使用
		tailf  nohup.out   # 實時檢視服務執行狀態

Filebeat 安裝使用

下載安裝

修改配置檔案(修改/etc/filebeat/filebeat.yml)

		filebeat.inputs:
		- type: log
		  enabled: true
		  paths:
		    - /var/log/*.log		# 抓取檔案日誌路徑
		    		# output.elasticsearch:
		#  hosts: ["ESHostIP:9200"]		# 輸出到ES

Filebeat到Lostash

Filebeat配置

（vim /etc/filebeat/filebeat.yml） shift + ：輸入set nu 顯示行號

			24:   enabled:  true				# 更改為true以啟用輸入配置
			28:   - /var/log/*.log           #   替換為要抓取的日誌檔案路徑
			73：  reload.enabled:  true	#		啟動Filebeat模組
			148： output.elasticsearch:   	  #  加上註釋；
			150:  hosts: ["localhost:9200"]   #   加上註釋；
			158： output.logstash:			#	去掉註釋；
			160： hosts: ["localhost:5044"]	#	去掉註釋，並修改localhost為logstash機器IP及對應埠號；

`測試配置檔案並啟動`

			filebeat  test  config  -e
			systemctl  start filebeat
			systemctl  enable filebeat

Logstash 安裝使用

解壓安裝

上傳包

tar xvf logstash-7.2.0.tar.gz -C /opt/

`啟動`

	/opt/logstash-7.2.0/bin/logstash -f /opt/配置檔名.yml
	## 後臺執行
	nohup  /opt/logstash-7.2.0/bin/logstash -f /opt/配置檔名.yml  &

Logstash到Elasticsearch

主要看配置檔案，配置檔案對了，直接按照上面命令啟動就可以了；

# Sample Logstash configuration for creating a simple
# Beats -> Logstash -> Elasticsearch pipeline.

input {
  beats {
    port => 5044
  }
}

filter {
        grok {
                match => {
               "message" => " %{DATA:log_date} %{TIME:log_localtime} %{JAVAFILE:name_file} %{WORD:workd}\[%{WORD:ls}\]\: %{DATA:log_date2} %{TIME:log_localtime2} %{WORD:year_tmp}\: %{WORD:name_2}\: %{WORD:} %{WORD:}\, %{JAVAFILE:}\: %{JAVAFILE:app_id}\, %{WORD}\: %{IP:ip}\, %{WORD:}\: %{INT}\, %{WORD}\: %{USERNAME:device_id}"
                }
        }
}

output {
   elasticsearch {
      hosts => ["http://ElasticsearchHostIP:9200"]
      index => "nginx_log-%{[@metadata][beat]}-%{[@metadata][version]}-%{+YYYY.MM.dd}"
   }
}
