CentOS 7にPHP-FPM 7.0をインストール（Remi's RPM repository）

# はじめに

Remi's RPM repositoryを利用してCentOS7にPHP-FPM7.0をインストール
親記事：[PHP, PHP-FPMの各種インストール方法とEOLまとめ](https://qiita.com/witchcraze/items/dfe3823554b7caba6f6a)
参考：[Remi's RPM repository](https://rpms.remirepo.net/wizard/)

## サポート

本手法で導入した場合、[PHP: Supported Versions] (https://www.php.net/supported-versions.php)/[PHP: Unsupported Branches](https://www.php.net/eol.php)より、2019-01-10がEOLになると思われる。
それ以降に報告された脆弱性や不具合への対応は実施されない可能性がある。
(メンテナーの御慈悲でその後もアップデートされているが、いつまで続くかはわからない)
