    bootstrap_servers => ["kafka1:9092,kafka2:9092,kafka3:9092"]
    group_id => "elk-consumer"
    auto_offset_reset => "latest"
    consumer_threads => 3
    decorate_events => true
    topics => ["elk_log_info"]
    type => "zc"
    codec => "json"
    max_partition_fetch_bytes => "5242940"
  }
}
output {
  elasticsearch {
    hosts => ["http://es1:9200","http://es2:9200","http://es3:9200"]
    index => "zc-logstash-%{+YYYY.MM.dd}"
  }
}

32.6.4. 将logstash安装目录授权给es用户
chown –R es:es /vmdata/logstash-7.7.0

32.6.5. 设置开机启动logstash服务
cd /etc/rc.d/init.d
vim logstash
