デーモンスーパーバイザーを使用して、Laravel フレームワークに基づいてスケジュールされたタスク (ミリ秒) を実装する

この記事の内容は、Laravel フレームワークに基づいてスケジュールされたタスク (ミリ秒) を実装するためのデーモン スーパーバイザーを使用する方法についてです。必要な方は参考にしていただければ幸いです。

この会社は、X 分以内に Y 秒ごとにインターフェイスのローテーション トレーニングを実装する必要があります。Linux に付属の crontab は、数分程度の精度しかないようです。秒単位で正確である必要がありますが、需要を満たしていません。 Linux自带的crontab貌似只精确到分钟，虽然可以到精确到秒，但是并不满足需求。

选型

公司项目都是 基于 Laravel 框架，所以这个没得选。守护进程用的 supervisor

選択

会社のプロジェクトはすべて Laravel フレームワークに基づいているため、選択の余地はありません。デーモンプロセスは supervisor を使用します。この人が私たちのニーズを満たすことができるかどうか見てみましょう
