    - name: Install nginx
      yum: name=nginx state=latest

    - name: copy nginx.conf
      copy: src=nginx.conf dest=/etc/nginx/nginx.conf
      notify: reload nginx

    - name: start nginx
      service: name=nginx state=started

  handlers:
    - name: reload nginx
      service: name=nginx state=reloaded

• notify => 変更があったらhandlersを呼ぶ
• handlers => 呼ばれる定義を宣言。名前大事
• handlersは最後にまとめて実行される
  • 同じnotifyが複数あっても実行は1回だけ
