CentOS 7にNginxをインストール

仕事も落ち着いて時間ができたので､勉強のつもりでCnetOS 7にNginxをインストールしてみました｡

nginx
https://ja.wikipedia.org/wiki/Nginx

Official Red Hat/CentOS packages
https://www.nginx.com/resources/wiki/start/topics/tutorials/install/

Red Hat/CentOSにはオフィシャルパッケージが提供されています｡

1. リポジトリの追加

変数を使わずに直接URLを記述しています｡

Shell
