ELK + Filebeat 日志分析系统

ELK + Filebeat 日志分析系统

架构图


环境
OS：CentOS 7.4
Filebeat： 6.3.2
Logstash: 6.3.2
Elasticsearch 6.3.2
Kibana: 6.3.2


FileBeat安装配置
安装
wget https://artifacts.elastic.co/dow ... at-6.3.2-x86_64.rpm
yum localinstall filebeat-6.3.2-x86_64.rpm


配置

这里以nginx日志为例做为演示html

配置文件：/etc/filebeat/filebeat.yml前端

filebeat.prospectors:
- input_type: log  #输入类型为log
  paths:  #日志路径
    - /usr/local/nginx/logs/*.access.log
  document_type: ngx-access-log  #日志类型
- input_type: log
  paths:
    - /usr/local/nginx/logs/*.error.log
  document_type: ngx-error-log
output.logstash:  #输出到Logstash（也能够输出到其余，如elasticsearch）
  hosts: ["10.1.4.171:1007"]


启动
systemctl enable filebeat
systemctl start filebeat


Logstash安装配置
安装
wget https://artifacts.elastic.co/dow ... /logstash-6.3.2.rpm
yum localinstall logstash-6.3.2.rpm


配置
Logstash须要自定义，自定义配置文件目录是/etc/logstash/conf.dnginx

这里新建一个filebeat.conf配置文件git

/etc/logstash/conf.d/filebeat.confgithub


input {
    #输入方式是beats
    beats {  
        port => "1007"  #监听1007端口（自定义端口）   
    }
}


filter {
    if [type] == "ngx-access-log" { #对日志类型为ngx-access-log进行处理。日志类型为filebeat配置定义
        grok {
            patterns_dir => "/usr/local/logstash/patterns"
            match => {  #对传过来的message字段作拆分，分割成多个易读字段
                message => "%{IPV4:remote_addr}\|%{IPV4:FormaxRealIP}\|%{POSINT:server_port}\|%{GREEDYDATA:scheme}\|%{IPORHOST:http_host}\|%{HTTPDATE:time_local}\|%{HTTPMETHOD:request_method}\|%{URIPATHPARAM:request_uri}\|%{GREEDYDATA:server_protocol}\|%{NUMBER:status}\|%{NUMBER:body_bytes_sent}\|%{GREEDYDATA:http_referer}\|%{GREEDYDATA:user_agent}\|%{GREEDYDATA:http_x_forwarded_for}\|%{HOSTPORT:upstream_addr}\|%{BASE16FLOAT:upstream_response_time}\|%{BASE16FLOAT:request_time}\|%{GREEDYDATA:cookie_formax_preview}"
            }
            remove_field => ["message"]   #已经将message字段拆分，能够将message字段删除
        }


        date {
            match => [ "time_local", "dd/MMM/yyyy:HH:mm:ss Z"]    #nginx日志中的时间替换@timestamp
            remove_field => ["time_local"]   #删除nginx日志时间字段
        }


        mutate {
            rename => ["http_host", "host"]   #nginx日志中http_host字段，替换host字段
        }
    }
}


output {
    elasticsearch {   # 输出到elasticsearch
        hosts => ["127.0.0.1:9200"]
        index => "logstash-%{type}-%{+YYYY.MM.dd}"   #输出索引格式
    }
}


启动
systemctl enable logstash
systemctl start logstash


Elasticsearch安装配置
安装
wget https://artifacts.elastic.co/dow ... ticsearch-6.3.2.rpm
yum localinstall elasticsearch-6.3.2.rpm


配置
/etc/elasticsearch/elasticsearch.ymlnpm


path.data: /var/lib/elasticsearch
path.logs: /var/log/elasticsearch
network.host: 0.0.0.0
http.port: 9200
#elasticsearch-head须要下列配置
http.cors.enabled: true  
http.cors.allow-origin: "*"

启动
systemctl enable elasticsearch
systemctl start elasticsearch

elasticsearch-head安装
elasticsearch-head用于链接elasticsearch，并提供一个前端管理页面cookie


git clone git://github.com/mobz/elasticsearch-head.git
cd elasticsearch-head
npm install
npm run start
open http://localhost:9100/


Kibana安装配置
安装
wget https://artifacts.elastic.co/dow ... na-6.3.2-x86_64.rpm
yum localinstall kibana-6.3.2-x86_64.rpm


配置
默认配置就好架构
启动
nohup /usr/share/kibana/bin/kibana &> /usr/share/kibana/logs/kibana.stdout &


nginx代理到kibana

安装nginxcors
yum install nginx


配置
/etc/nginx/conf.d/kibana.confelasticsearch


server {
    listen 80;
    server_name test.kibana.com;


    root html;
    access_log  /var/log/nginx/test.kibana.com.access.log main;
    error_log   /var/log/nginx/test.kibana.com.error.log;


    proxy_next_upstream http_502 http_504 error timeout invalid_header;
    proxy_connect_timeout     10;
    proxy_read_timeout        30;
    proxy_send_timeout        180;
    proxy_ignore_client_abort on;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_buffering           off;
    proxy_set_header Host $host;


    location /monitor {
        default_type text/plain;
        return 200 "OK";
    }


    location /echoip {
       default_type text/plain;
       return 200 $http_x_forwarded_for,$remote_addr;
    }


    location / {
        expires off;
        if ($server_port = "80") {
            proxy_pass http://127.0.0.1:5601;
        }
        proxy_pass  https://127.0.0.1:5601;


    }
}


启动
systemctl enable nginx
systemctl start nginx

本文只是简单介绍了一下ELK+Filebeat日志分析系统的安装配置，以及一个简单的nginx日志处理过程。要想更细致的学习ELK体系
