Rails5.0.0 + puma3.6 + nginx1.10.1連携

Last updated at Posted at 2016-10-08

Rubyから少し離れていると標準が大きく変わっていました。
備忘録も兼ねて、メモ。

今回はRails5を使ってWEBアプリを構築してみたいと存じます。
これまではunicornを利用してたのですが、5からpumaが
より標準に近い形になっていくように見受けられました。

SWのバージョン
さくらのクラウド(CentOS7.2)を利用します。

取り急ぎ、連携と動作を確認できました。
Rails5、pumaどちらも、きちんと勉強しなおす必要がありますね。
