ELK集群模式部署

架构拓扑图为：

准备工作：

下载资源包：

Elasticsearch： wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.2.4.tar.gz  # 这一步用docker启动，可以不用下载。

Kibana: wget https://artifacts.elastic.co/downloads/kibana/kibana-6.2.4-linux-x86_64.tar.gz

Logstash:wget https://artifacts.elastic.co/downloads/logstash/logstash-6.2.4.tar.gz

Filebeat:wget https://artifacts.elastic.co/downloads/beats/filebeat/filebeat-6.2.4-linux-x86_64.tar.gz

安装：

根据拓扑图把对应的服务安装在对应的服务器。

tar xvf kibana-6.2.3-linux-x86_64.tar.gz -C /usr/local/

tar xvf logstash-6.2.4.tar.gz -C /usr/local/

tar -xvf filebeat-6.2.4-linux-x86_64.tar.gz -C /usr/local/

grok调试地址：http://grokdebug.herokuapp.com/

如需调试请修改output成以下，方便debug

output {
        stdout {
        codec    => rubydebug
    }
}

filebeat(192.168.11.6)
