ln -s /opt/product/data/elk/filebeatdata /opt/product/filebeat-6.0.0/data
/opt/product/filebeat-6.0.0/filebeat -e -c filebeat.yml

  • 构建镜像

    elk/filebeat$ docker build -t filebeat:v1.0 .

  • 配置filebeat

    // 在/opt/product/data/elk目录下 创建filebeat.yml
filebeat.prospectors:
  - input_type: log
    document_type: tomcataccess
  paths:
     - /opt/product/data/logs/tomcat/localhost_access_log*.txt

    docker run --name filebeat -d -ti -v /opt/product/data:/opt/product/data filebeat:v1.0 /bin/bash

x-pack

  • 安装 

    ./elasticsearch-plugin install x-pack

  • 设置密码

https://www.elastic.co/guide/en/x-pack/current/setting-up-authentication.html#set-built-in-user-passwords

./setup-passwords interactive
    Enter password for [elastic]:
    Reenter password for [elastic]:
    Enter password for [kibana]:
    Reenter password for [kibana]:
    Enter password for [logstash_system]:
    Reenter password for [logstash_system]:
    Changed password for user [kibana]
    Changed password for user [logstash_system]
    Changed password for user [elastic]

  • logstash配置

    input { stdin { } }
output {
  elasticsearch {
    hosts => ["192.168.107.23:9200"]
    user => elastic
    password => elastic
  }
  stdout { codec => rubydebug }
}

    同理，kibana也可以配置，调用es接口也需要用户密码

说明

脚本和启动项参数中的/opt/product/data均以自己要设定的挂载目录一致
