实战之elasticsearch集群及filebeat server和logstash server

环境

elasticsearch集群节点环境为172.16.100.120:9200，172.16.100.121:9200，172.16.100.122:9200
logstash server服务端为172.16.100.121
filebeat server服务端为172.16.100.121
httpd服务产生日志信息 172.16.100.121 
redis服务端172.16.253.181
kibana服务端172.16.253.181
tomcat server端172.16.253.145

网络拓扑图

elasticsearch集群构建如上，在此省略

filebeat server

下载filebeat程序包
    https://www.elastic.co/downloads/beats/filebeat

[root@node4 ~]# ls filebeat-5.5.1-x86_64.rpm 
filebeat-5.5.1-x86_64.rpm

安装filebeat

[root@node4 ~]# yum -y install filebeat-5.5.1-x86_64.rpm
[root@node4 ~]# rpm -ql filebeat

编辑filebeat.yml文件

[root@node2 ~]# vim /etc/filebeat/filebeat.yml
- input_type: log
    - /var/log/httpd/access_log*    指定数据的输入路径为access_log开头的所有文件
output.logstash:     \\数据输出到logstash中
    # The Logstash hosts
    hosts: ["172.16.100.121:5044"]   \\指定logstash服务端

启动服务

[root@node4 ~]# systemctl start filebeat 

logstash server

安装java环境

[root@node2 ~]# yum -y install java-1.8.0-openjdk-devel

下载logstash程序

https://www.elastic.co/downloads/logstash

安装logstash程序

[root@node2 ~]# ll logstash-5.5.1.rpm 
-rw-r--r--. 1 root root 94158545 Aug 21 17:06 logstash-5.5.1.rpm
[root@node4 ~]# rpm -ivh logstash-5.5.1.rpm 

编辑logstash的配置文件

[root@node2 ~]# vim /etc/logstash/logstash.yml文件配置
path.data: /var/lib/logstash   			数据存放路径
path.config: /etc/logstash/conf.d    	配置文件的读取路径
path.logs: /var/log/logstash			日志文件的保存路径
		
[root@node2 ~]# vim  /etc/logstash/jvm.options环境文件
-Xms256m   启用的内存大小
-Xmx1g

编辑/etc/logstash/conf.d/test.conf 文件

[root@node4 ~]# vim /etc/logstash/conf.d/test.conf 
input {
    beats {
        port => 5044
    }
}

filter {
    grok {
        match => {
            "message" => "%{COMBINEDAPACHELOG}"
        }
    remove_field => "message"   \\只显示message字段的数据
    }
}

output {
    elasticsearch {
        hosts => ["http://172.16.100.120:9200","http://172.16.100.121:9200","http://172.16.100.122:9200"]
        index => "logstash-%{+YYYY.MM.dd}"
        action => "index"
    }
}

测试/etc/logstash/conf.d/test.conf文件语法

[root@node2 ~]# /usr/share/logstash/bin/logstash -t -f /etc/logstash/conf.d/test.conf

执行/etc/logstash/conf.d/test.conf文件

[root@node2 ~]#/usr/share/logstash/bin/logstash -f /etc/logstash/conf.d/test.conf

客户端访问测试索引信息是否生成

[root@node5 ~]#curl -XGET '172.16.100.120:9200/_cat/indices'
green open logstash-2017.10.12 baieaGWpSN-BA28dAlqxhA 5 1 27 0 186.7kb 93.3kb

从redis插件读取采集数据

Redis

[root@node4 ~]# yum -y install redis
[root@node4 ~]# vim /etc/redis.conf 
bind 0.0.0.0    			监听所有地址
requirepass danran   	设定密码为danran
[root@node4 ~]# systemctl restart redis

连接测试redis是否正常

[root@node4 ~]# redis-cli -h 172.16.253.181 -a danran
172.16.253.181:6379> 

配置logstash server文件

[root@node2 ~]# vim /etc/logstash/conf.d/redis-input.conf
input {
    redis {
        host => "172.16.253.181"
        port => "6379"
        password => "danran"
        db => "0"
        data_type => "list"    \\定义数据类型为列表格式
        key => "filebeat"   \\定义key为filebeat，与filebeat.yml定义key一致
    }
}

filter {
    grok {
        match => {
           "message" => "%{COMBINEDAPACHELOG}"
        }
    remove_field => "message"
    }
    mutate {
        rename => {"clientip" => "[httpd][clientip]" }
    }
}

output {
    elasticsearch {
        hosts => ["http://172.16.100.120:9200","http://172.16.100.121:9200","http://172.16.100.122:9200"]
        index => "logstash-%{+YYYY.MM.dd}"
        action => "index"
    }
}

    - /var/log/httpd/access_log*    指定数据的输入路径为access_log开头的所有文件

#-----------------------redis output ---------------------------

output.redis:
    hosts: ["172.16.253.181"]    \\redis服务端
    port: "6379"
    password: "danran" 		  \\redis密码
    key: "filebeat"				  \\定义key，与redis-input.conf文件中input字段的key保存一致
    db: 0    					  \\指定输出的数据库为0
    timeout: 5
