インストール時警告

curl -sS https://getcomposer.org/installer | php
PHP Warning: Module 'intl' already loaded in Unknown on line 0

Downloading...
Composer (version 1.6.2) successfully installed to: /root/composer.phar
Use it: php composer.phar
これは、php.ini で extension=intl.so をコメントアウトすることで消えたけど
CakePHP3 をインストールする際に intl は必要なはずなので、後ほど試す。
起動時警告
実は上記起動時に、下記2行目の警告が出ていた。
php composer.phar
Do not run Composer as root/super user! See https://getcomposer.org/root for details
あら、Composer って、root で利用してはいけないのね~。
実行ファイルを移動させて、一般ユーザに戻って利用したら
上記警告は出なくなった。
ちなみに、インストールを root でしたせいか
実行ファイルを移動しておかないと、php composer.phar では、実行できず
php composer.phar
Could not open input file: composer.phar
このように怒られた。。。
