CentOS 5にPHP5.3をインストールしよう！

ここでは、PHP5.3のインストール手順を掲載しています。

PHP5.1から5.3へ

CentOS 5のPHPは通常5.1.6というバージョンがインストールされます。

この5.1.6というバージョンは非常に古く(2006年)、最近のWordPressやphpMyAdminなどのWebアプリケーションに対応していません。

CentOS 6の登場で、このPHPも5.3.3にアップデートされました。CentOS 5では、従来のバージョンとは分けて管理され、php53というパッケージになっています。

PHPのアンインストール

すでに5.1.6がインストールされている場合は、先にPHPを削除します。

バージョンを確認してみましょう。5.3.3になっていればOKです。

[root@co ~]# php -v

PHPの設定

続いて、設定を行います。基本的に5.1.6と変わりません。

先に5.1.6がインストールされていた場合、設定ファイルを引き継げるっぽいので、確認程度で大丈夫でしょう。
