1.实验环境:

  使用8台CentOS主机,实现filebeat+redis+logstash+els集群(3台)+kibana来完成搜索日志相关内容,目标:filebeat来完成收集本机http数据,收集完成后发送给redis,redis主要是来避免数据量过大,logstash处理不过来,logstash是用来格式化数据,将收集来的数据格式化成指定格式,els集群是将格式化完成的数据,进行文档分析,,构建索引,提供查询等操作,kibana提供图形化界面查询的组件

2.实验步骤

本实验所用的四个软件包全部都是5.6版本
下载相关网站:https://www.elastic.co/cn/products
配置前注意事项:1.关闭防火墙。2.关闭SELinux。3.同步时间
步骤1.实现收集httpd服务的日志文件,并将数据发送给redis服务
http+filebeat服务器相关配置

[root@filebeat ~]# yum install -y httpd
[root@filebeat ~]# echo test > /var/www/html/index.html
[root@filebeat ~]# systemctl start httpd
[root@filebeat ~]# rpm -ivh filebeat-5.6.10-x86_64.rpm
相关配置文件
/etc/filebeat/filebeat.full.yml  #模板配置文件
/etc/filebeat/filebeat.yml 主配置文件
配置redis需要从模板文件中将模板复制到主配置文件中
output.redis:
  enabled: true   #开启
  hosts: ["172.18.100.2:6379"] #redis服务器
  port: 6379 
  key: filebeat  #key的名字
  password:  centos #密码若没有设置则不用填
  db: 0 #写入哪个数据库
  datatype: list  #数据类型
  worker: 1  #开几个进行写数据
  loadbalance: true  #是否支持将多个redis中写入
[root@filebeat ~]# systemctl start filebeat

redis相关配置

[root@redis ~]# yum install -y redis
[root@redis ~]# vim /etc/redis.conf
bind 0.0.0.0
port 6379
requirepass centos
[root@nginx1 ~]# systemctl start redis
增加访问日志,在redis中查询
[root@nginx1 ~]# redis-cli -a centos
127.0.0.1:6379> KEYS *
1) "filebeat"   #即可验证成功

步骤2配置logstash从redis中拿数据,并且格式化,然后存入elasticsearch,并且显示
logstash相关配置,配置该服务之前需要安装JVM相关组件

[root@nginx2 ~]# rpm -ivh logstash-5.6.10.rpm
[root@nginx2 ~]# cd /etc/logstash/conf.d/
[root@nginx2 conf.d]# vim redis-logstash-els.conf  #创建文件,只要以.conf结尾即可
input {
        redis {
                batch_count => 1
                data_type => "list"
                key => "filebeat"
                host => "172.18.100.2"
                port => 6379
                password => "centos"
                threads => 5
        }
}
filter {
        grok {
                match => {
                        "message" => "%{HTTPD_COMBINEDLOG}"
                }
                        remove_field => "message"
        }
        date {
                match => ["timestamp","dd/MM/YYYY:H:m:s Z"]
                remove_field => "timestamp"
        }

}
output {
        stdout {
                codec => rubydebug
        }
}
在终端显示格式化好的内容
[root@nginx2 conf.d]# /usr/share/logstash/bin/logstash -f redis-logstash-els.conf
{
        "request" => "/",
          "agent" => "\"curl/7.29.0\"",
         "offset" => 93516,
           "auth" => "-",
          "ident" => "-",
     "input_type" => "log",
           "verb" => "GET",
         "source" => "/var/log/httpd/access_log",
           "type" => "log",
           "tags" => [
        [0] "_dateparsefailure"
    ],
       "referrer" => "\"-\"",
     "@timestamp" => 2018-06-20T15:21:20.094Z,
       "response" => "200",
          "bytes" => "5",
       "clientip" => "127.0.0.1",
           "beat" => {
            "name" => "filebeat.test.com",
        "hostname" => "filebeat.test.com",
         "version" => "5.6.10"
    },
       "@version" => "1",
    "httpversion" => "1.1",
      "timestamp" => "20/Jun/2018:11:21:19 -0400"
}
将output修改成传递给els集群
output {
        elasticsearch {
                hosts => ["http://172.18.100.4:9200/","http://172.18.100.5:9200/","http://172.18.100.6:9200/"]
                index => "logstash-%{+YYYY.MM.dd}"
                document_type => "apache_logs"
        }
}

检查没有错误即可
[root@nginx2 conf.d]# /usr/share/logstash/bin/logstash -f redis-logstash-els.conf  -t
WARNING: Could not find logstash.yml which is typically located in $LS_HOME/config or /etc/logstash. You can specify the path using --path.settings. Continuing using the defaults
Could not find log4j2 configuration at path /usr/share/logstash/config/log4j2.properties. Using default config which logs errors to the console
Configuration OK

步骤3配置els集群服务,需要先安装JVM服务
节点1:

[root@tomcat1 ~]# rpm -ivh elasticsearch-5.6.10.rpm
[root@els1 ~]# vim /etc/elasticsearch/elasticsearch.yml
cluster.name: myels
node.name: els.test.com
network.host: 172.18.100.4
http.port: 9200
discovery.zen.ping.unicast.hosts: ["172.18.100.4", "172.18.100.5","172.18.100.6"]
discovery.zen.minimum_master_nodes: 2

节点2:

[root@tomcat1 ~]# rpm -ivh elasticsearch-5.6.10.rpm
[root@els1 ~]# vim /etc/elasticsearch/elasticsearch.yml
cluster.name: myels
node.name: els.test.com
network.host: 172.18.100.5
http.port: 9200
discovery.zen.ping.unicast.hosts: ["172.18.100.4", "172.18.100.5","172.18.100.6"]
discovery.zen.minimum_master_nodes: 2

节点3:

[root@tomcat1 ~]# rpm -ivh elasticsearch-5.6.10.rpm
[root@els1 ~]# vim /etc/elasticsearch/elasticsearch.yml
cluster.name: myels
node.name: els.test.com
network.host: 172.18.100.6
http.port: 9200
discovery.zen.ping.unicast.hosts: ["172.18.100.4", "172.18.100.5","172.18.100.6"]
discovery.zen.minimum_master_nodes: 2

在els任意一个节点上查看数据

[root@els1 ~]# curl -XGET ‘http://172.18.100.4:9200/logstash-2018.06.21?pretty=true‘  显示传过来的数据
    "settings" : {
      "index" : {
        "refresh_interval" : "5s",
        "number_of_shards" : "5",
        "provided_name" : "logstash-2018.06.21",
        "creation_date" : "1529545212157",
        "number_of_replicas" : "1",
        "uuid" : "3n74gNpCQUyCLq58vAwL6A",
        "version" : {
          "created" : "5061099"
        }
      }
    }
  }
}

步骤4:配置Nginx反向代理,若其中有一个故障,还可以被查询

[root@mysql1 ~]# yum install -y nginx
[root@mysql1 ~]# vim /etc/nginx/conf.d/test.conf
upstream ser {
        server 172.18.100.4:9200;
        server 172.18.100.5:9200;
        server 172.18.100.6:9200;
}
server {
        listen 80;
        server_name www.test.com;
        root /app/;
        index index.html;
        location / {
                proxy_pass http://ser;
        }
}

步骤5:配置kibana实现图形化查看

server.host: "0.0.0.0"
server.basePath: ""
server.name: "172.18.100.8"
elasticsearch.url: "http://172.18.100.7:80"  #反向代理服务器
elasticsearch.preserveHost: true
kibana.index: ".kibana"
