「SSH アカウントを作成する」をお読みになり、OpenSSH や Tera Term といったものを用意して SSH 接続をすれば、 /var/www/html/moodle/ あたりに Moodle が見つかると思いますので、それを emacs や vi で修正するのがよくある方法だと思います。(運用環境を直接変更することが望ましくなければ、test 環境を別途用意することになります。)

なお、ConoHa WING は「レンタルサーバ」ですので、VPS などの上に Moodle を設置するよりも難易度がかなり高いと思われます。「レンタルサーバ」上に Moodle を設置すると、VPS には存在しない様々な制約に直面することとなり原因を調べるだけで苦労します。
