ラズベリーパイ+pythonを使ってみる – かんたんなwebアプリがパパっと作れる flask のインストール –

flask(フラスク)＝pythonでよく使われているwebアプリケーションフレームワークです。PHPでいうところのCakePHPをもっとかんたんにした感じです。RubyでいうとSinatraです

使い方は、検索すると出てくるかと思います

pythonが動くのが遅いなぁ…という場合は

ラズベリーパイのCPUを高速にすることはできませんが、高速なさくらのVPSを借りてそれにUbuntuをインストールすることで、ラズベリーパイとほぼ同じ手順で高速なサーバを構築することができます(^O^)

自分も使っていますが、CPUはラズベリーパイのおよそ10倍速いのでブログソフトWordpressもサクサク動いてとても快適です(・∀・)
ラズベリーパイでサーバ構築の練習をし、VPSで高速安定なサーバを構築するとCPUやメモリも自由に使え、勉強する時間も少なく安定したサーバが作れるためコスパが最高だと思います
