ELKのインストール

2つのcentos7を準備します

	配置：2核心2G内存
	规划如下：
	ip地址：
	192.168.179.142：
	jdk
	kibana
	elasticsearch

	192.168.179.145:
	jdk
	logstash

 1. 关闭防火墙
[root@localhost src]# systemctl stop firewalld
[root@localhost src]# setenforce 0
 2. 安装jdkk
 [root@localhost ELK]# rpm -ivh jdk-8u131-linux-x64_.rpm 
	验证 [root@localhost ELK]# java -version
 3. 安装elasticsearch
 [root@localhost ELK]# rpm -ivh elasticsearch-6.6.2.rpm
 
 4. 修改配置文件
 	vim /etc/elasticsearch/elasticsearch.yml
 	cluster.name: myson
	node.name: node-1
	path.data: /var/lib/elasticsearch
	path.logs: /var/log/elasticsearch
	network.host: 192.168.179.142
	http.port: 9200
	开启服务   systemctl start elasticsearch
 5. 查看服务是否运行
 	[root@localhost elasticsearch]# tailf /var/log/elasticsearch/my.log 
 6. 安装kibana
	[root@localhost ELK]# rpm -ivh kibana-6.6.2-x86_64.rpm	
 7.修改配置文件
 root@localhost kibana]# cat kibana.yml |grep -v '^#'|sed '/^$/d'
	server.port: 5601
	server.host: "192.168.179.142"
	elasticsearch.hosts: ["http://192.168.179.142:9200"]
 8.启动kibana
 	systemctl start kibana
# 	
 

192.168.179.145で操作

1. JDKをインストールする
2. logstashをインストールします

    root@localhost ELK]# rpm -ivh logstash-6.6.0.rpm
	vim /etc/logstash/conf.d/msg.conf
input{
    
    
	file{
    
    
		path => "/var/log/messages"
		type => 'msg-log'
		start_position => "beginning"
	}
}

output{
    
    
	elasticsearch{
    
    
		hosts => "192.168.179.142:9200"
		index => "msg_log-%{+YYYY.MM.dd}"
	}
}	

vim /etc/logstash/conf.d
input{
    
    
	file{
    
    
		path => "/var/log/secure"
		type => 'sec-log'
		start_position => "beginning"
	}
}

output{
    
    
	elasticsearch{
    
    
		hosts => "192.168.179.142:9200"
		index => "sec_log-%{+YYYY.MM.dd}"
	}
}

编写pipelines.yaml文件

[root@localhost ~]# vim /etc/logstash/pipelines.yml


- pipeline.id: msg
 path.config: "/etc/logstash/conf.d/msg.conf"
- pipeline.id: sec
 path.config: "/etc/logstash/conf.d/secure.conf"
