Elasticsearch + Kibana + Embulk on VirtualBox
VirtualBoxに2台の仮想マシンを用意して、1台目はDockerを利用したElasticsearchとKibana環境、2台目は仮想マシンにEmbulkをインストールしてログを取り込んでみた時の記録です。
| 項目 | 対象 |
|---|---|
| Hypervisor | VirtualBox |
| OS | CentOS Linux release 7.4.1708 (Core) |
| 仮想マシン01 Embulk | 192.168.56.28 |
| 仮想マシン02 Elasticsearch Kibana | 192.168.56.29 |
※OSについては、当方の環境と全く同じでない場合もあるので足りない場合は、yum等でインストールしてください。
1.仮想マシン01 Elasticsearch Kibana
Elasticsearch Kibana
ElasticsearchとKibanahaは、コンテナー利用とするためDockerとDocker-Composeをインストールします。
コマンド
# yum install -y docker
# systemctl enable docker
# systemctl start docker
# curl -L https://github.com/docker/compose/releases/download/1.9.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
# chmod +x /usr/local/bin/docker-compose
ElasticsearchとKibanaのdocker-compose.ymlを作成します。
コマンド
# vim docker-compose.yml
----------------------------------------------------
elasticsearch:
image: elasticsearch
container_name: elasticsearch
ports:
- "9200:9200"
environment:
ES_JAVA_OPTS: '-Xms2048m -Xmx2048m'
kibana:
image: kibana
container_name: kibana
links:
- elasticsearch:elasticsearch
ports:
- "5601:5601"
----------------------------------------------------
:wq
ElasticsearchとKibanaのコンテナーを起動します。
コマンド
# docker-compose up -d

map.jsonファイルを作成します。読み込むログファイルのカラム要素などが不明な場合は、typeをstring、indexをnot_analyzedでカラム数分指定して、とりあえず読み込めるようにします。今回は31カラムあるログです。（これは力業的な感じです。。）
コマンド
# vim import_log.json

マッピングをcurlで設定します。 access_log はマッピングを登録するインデックス名です。
コマンド
# curl -XPUT '192.168.56.29:9200/embulk_access_log' -d @import_log.json
{"acknowledged":true,"shards_acknowledged":true,"index":"embulk_access_log"}
Embulkを実行します。
コマンド

ブラウザを起動してKibanaで確認します。
「Index pattern」にembulk_access_logを指定し、「Create」ボタンをクリックします。
Kibanaについては、取り込んだログを可視化して分析などできるのですが、これはこれで勉強が必要ですね。
