ELK补充之Filebeat

https://www.elastic.co/cn/downloads/past-releases/filebeat-6-5-4
https://artifacts.elastic.co/downloads/beats/filebeat/filebeat-6.5.4-x86_64.rpm

适用于没有JDK环境的，日志量非常大的

使用filebeat替代logstash收集日志

安装

yum install filebeat-6.5.4-x86_64.rpm
cp filebeat.yml{,.bak}

配置filebeatgrep -E -v "#|^$" filebeat.yml

filebeat.inputs:
- type: log
  enabled: true
  paths:
    - /var/log/messages
  exclude_files: ['.gz$']
  fields:
    type: syslog
    host: "192.168.10.102"

filebeat.config.modules:
  path: ${path.config}/modules.d/*.yml
  reload.enabled: false
setup.template.settings:
  index.number_of_shards: 3
setup.kibana:
processors:
  - add_host_metadata: ~
  - add_cloud_metadata: ~

output.file:
  path: /tmp
  filename: filebeat.log
  
systemctl restart filebeat
ls /tmp/filebeat.log

filebeat收集单个类型日志并写入redis

配置filebeat将日志写入至redis

grep -E -v "#|^$" filebeat.yml
filebeat.inputs:
- type: log
  enabled: true
  paths:
    - /var/log/messages
  exclude_files: ['.gz$']
  fields:
    type: syslog
    host: "192.168.10.102"

filebeat.config.modules:
  path: ${path.config}/modules.d/*.yml
  reload.enabled: false
setup.template.settings:
  index.number_of_shards: 3
setup.kibana:
processors:
  - add_host_metadata: ~
  - add_cloud_metadata: ~

output.redis:
  hosts: ["192.168.10.254:6379"]
  key: "filebeat"
  db: 1
  timeout: 5
  password: password
  
systemctl restart filebeat

配置其他logstash服务器从redis读取数据

cat redis-es.conf 
input {
  redis {
    data_type => "list"
    key => "filebeat"
    host => "192.168.10.254"
    port => "6379"
    db => "1"
    password => "password"
  }
}

output {
  if [fields][type] =="syslog"{
    elasticsearch {
      hosts => ["192.168.10.100:9200"]
      index => "filebeat-syslog-%{+YYYY.MM.dd}"
}}}

日志写入数据库

入数据库的目的是用于持久化保存重要数据，比如状态码、客户端IP、客户端浏览器版本等等，用于后期按月做数据统计等
https://dev.mysql.com/downloads/connector/j/

授权用户登录

create database elk  character set utf8 collate utf8_bin;
grant all privileges on elk.* to elk@"%" identified by 'pass';
flush  privileges;

连接数据库创建表

mysql -hnode -uelk -ppass

create table elklog(clientip varchar(128),upstreamtime varchar(128),url varchar(256),status int(16),time TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP) DEFAULT CHARSET=utf8 COLLATE=utf8_bin;

logstash配置mysql-connector-java包
