主: 192.168.227.170
从: 192.168.227.171
从: 192.168.227.173
三台都安装zookeeper和kafka

时间同步

修改主机名

三台都配置/etc/hosts文件

测试能否ping通

1.安装java环境

2.安装zookeeper

在最下面添加三行：
server.1=192.168.227.170:2888:3888
server.2=192.168.227.171:2888:3888
server.3=192.168.227.173:2888:3888

启动zookeeper

查看状态，三台分别为：

3.安装kafka

第一台

第二台

第三台

启动kafka

查看日志

模拟生产者和消费者进行验证
创建
/usr/local/kafka/bin/kafka-topics.sh --create --zookeeper 192.168.227.170:2181 --replication-factor 2 --partitions 3 --topic wg001

生产者
/usr/local/kafka/bin/kafka-console-producer.sh --broker-list 192.168.227.170:9092 --topic wg001
消费者
/usr/local/kafka/bin/kafka-console-consumer.sh --bootstrap-server 192.168.227.170:9092 --topic wg001 --from-beginning
验证

4.安装filebeat
配置filebeat源

[filebeat-6.x]
name=Elasticsearch repository for 6.x packages
baseurl=https://artifacts.elastic.co/packages/6.x/yum
gpgcheck=1
gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
enabled=1
autorefresh=1
type=rpm-md

监控一个日志

#=========================== Filebeat inputs =============================

filebeat.inputs:

• type: log

  Change to true to enable this input configuration.

  enabled: true

  Paths that should be crawled and fetched. Glob based paths.

  paths:
  • /var/log/messages

#================================ Outputs =====================================
#-------------------------- Elasticsearch output ------------------------------
output.kafka:

Array of hosts to connect to.

enabled: true
hosts: [“192.168.227.170:9092”,“192.168.227.171:9092”,“192.168.227.173"9092”]
topic: messages

监控两个日志

启动filebeat

消费者

5.安装Elasticsearch

查看elasticsearch日志

6.安装logstash

7.安装kibana

访问 http://ip:5601

在上面的基础上做监控nginx的日志
先安装nginx

压测nginx，让nginx产生日志

创建nginx主题

创建nginx生产者

去nginx消费者查看是否有数据产生

去logstash编辑nginx.conf

重启logstash，查看logstash日志看是否有报错

访问 http://ip:5601

如果不能创建，使用ab -n 1000 -c 1000 http://ip/index.html压测nginx，是nginx产生日志

Nginx匹配正则

NGINXACCESS %{IPORHOST:client_ip} (%{USER:ident}|- ) (%{USER:auth}|-) [%{HTTPDATE:timestamp}] “(?:%{WORD:verb} (%{NOTSPACE:request}|-)(?: HTTP/%{NUMBER:http_version})?|-)” %{NUMBER:status} (?:%{NUMBER:bytes}|-) “(?:%{URI:referrer}|-)” “%{GREEDYDATA:agent}”

开启debug模式测试

开启logstash,

input {
kafka {
bootstrap_servers => [“192.168.116.128:9092,192.168.116.129:9092,192.168.116.130:9092”]
group_id => “logstash”
topics => “nginx”
consumer_threads => 5
}
}

filter {
json {
source => “message”
}
mutate {
remove_field => [“version”,“auth”,“log”,“prospector”,“input”,“offset”,“http_version”,“fields”,“log_topics”,“beat”,“ident”,“source”,“host”]
}
grok {
match => {“message” => “%{NGINXACCESS}” }
}
}

output {
elasticsearch {
hosts => “192.168.116.130:9200”
index => “nginx-%{+YYYY.MM.dd}”
}
#stdout {
# codec => rubydebug
#}
}
