6、ELK+Kafka

环境

10.0.0.51: Logstash、Kafka、Filebeat

一、Zookkeeper和Kafka安装

1、依赖

Kafka

Kafka依赖于Zookkeeper
两个都依赖于Java

Kafka依赖于Zookeeper

官方网站：https://zookeeper.apache.org/
下载ZK的二进制包
解压到对应目录完成安装

2、下载解压ZK，复制默认配置文件

tar -zxf zookeeper-3.4.13.tar.gz
cp /usr/local/zookeeper-3.4.13/conf/zoo_sample.cfg  /usr/local/zookeeper-3.4.13/conf/zoo.cfg

3、更改配置文件，监听所有地址
vim /usr/local/zookeeper-3.4.13/conf/zoo.cfg

clientPortAddress=0.0.0.0

3、启动zookeeper

/usr/local/zookeeper-3.4.13/bin/zkServer.sh start

4、zookeeper监听的端口为2181

[[email protected] local]# netstat -tlunp | grep 2181
tcp6       0      0 :::2181                 :::*                    LISTEN      15295/java

5、Kafka下载解压
Kafka官网：http://kafka.apache.org/

 tar -zvxf kafka_2.11-2.1.1.tgz
mv kafka_2.11-2.1.1 /usr/local/kafka_2.11

6、更改kafka的配置：更改监听地址、更改连接zk的地址
vim /usr/local/kafka_2.11/config/server.properties

listeners=PLAINTEXT://10.0.0.51:9092
zookeeper.connect=10.0.0.51:2181

7、启动

前台启动

/usr/local/kafka_2.11/bin/kafka-server-start.sh /usr/local/kafka_2.11/config/server.properties

后台启动

nohup /usr/local/kafka_2.11/bin/kafka-server-start.sh /usr/local/kafka_2.11/config/server.properties >/tmp/kafka.log 2>&1 &

8、Kafka监听9092端口

[[email protected] local]# netstat -tlunp | grep 9092
tcp6       0      0 10.0.0.51:9092          :::*                    LISTEN      15475/java

二、filebeat–>kafka–>logstash

1、修改filebeat配置文件，然后重新启动filebeat，将Filebeat日志发送到Kafka
vim /usr/local/filebeat-6.6.0/filebeat.yml

[[email protected] local]# cat /usr/local/filebeat-6.6.0/filebeat.yml
filebeat.inputs:
- type: log
  tail_files: true
  backoff: "1s"
  paths:
      - /usr/local/nginx/logs/access.log
  fields:
    type: access
  fields_under_root: true

- type: log
  tail_files: true
  backoff: "1s"
  paths:
      - /var/log/secure
  fields:
    type: secure
  fields_under_root: true

output:
  kafka:
    hosts: ["10.0.0.51:9092"]
    topic: wangxiaoyu

2、修改Logstash的配置，从kafka读取数据，重启Logstash
如果没有配置codec => “json”，对从kafka读取的数据进行json解析，logstash虽然可以读取消费kafka里的数据，但没法将数据发送个elasticsearch，我日志也不是json格式的呀。。。。应该是kafka默认会把数据格式转为json。

[[email protected] local]# cat /usr/local/logstash-6.6.0/config/logstash.conf
input {
  kafka {
    codec => "json"
    bootstrap_servers => "10.0.0.51:9092"
    topics => ["wangxiaoyu"]
    group_id => "wangxiaoyu"
  }
}

filter {
  mutate {
    rename => { "[host][name]" => "host" }
  }
}

output{

  if [type] == "access" {
    elasticsearch {
      hosts => ["http://10.0.0.50:9200"]
      index => "access-%{+YYYY.MM.dd}"
    }
  }

  if [type] == "secure" {
    elasticsearch {
      hosts => ["http://10.0.0.50:9200"]
      index => "secure-%{+YYYY.MM.dd}"
    }
  }

}

3、Kafka查看队列信息，有个消费者可以查看读取到哪里了。

[[email protected] bin]# cd /usr/local/kafka_2.11/bin
[[email protected] bin]# ./kafka-consumer-groups.sh  --bootstrap-server 10.0.0.51:9092 --list
wangxiaoyu
[[email protected] bin]# ./kafka-consumer-groups.sh  --bootstrap-server 10.0.0.51:9092 --group wangxiaoyu --describe

TOPIC           PARTITION  CURRENT-OFFSET  LOG-END-OFFSET  LAG             CONSUMER-ID                                     HOST            CLIENT-ID
wangxiaoyu      0          14              14              0               logstash-0-d5c3e806-655a-4d8c-870f-3daabffb38ce /10.0.0.51      logstash-0

4、查看日志
6、ELK+Kafka

环境

一、Zookkeeper和Kafka安装
