今回はHerokuを使ってみようの会ですｗ
今回の参考先もmacを買って、今すぐherokuでruby1.9.3 + rails3.2しよう！ですｗｗ
ありがとうございますm(__)m
Herokuの登録は
macを買って、今すぐherokuでruby1.9.3 + rails3.2しよう！
の『herokuアカウントを作成』から読んでね。
アカウントが作成出来たら、参考先をそのまま続けてやってきましょうー。
ssh公開鍵を作成する
以下コマンドを打って、Enterを押すと出来上がり。
$ ssh-keygen -b 2048
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/xxxx/.ssh/id_rsa): ←Enter押す
Created directory '/Users/xxxx/.ssh'.
Enter passphrase (empty for no passphrase): ←入力せずにEnter押す
Enter same passphrase again: ←入力せずEnter押す
Your identification has been saved in /Users/xxxx/.ssh/id_rsa.
Your public key has been saved in /Users/xxxx/.ssh/id_rsa.pub.
fingerprintとか表示されるので、眺めて終了。
作った公開鍵を登録

rvm gemsetを作成する
rvm gemsetってなんじゃらホイと思ってぐぐってみました。
RVM gemset とは？によると、rubyのバージョンと使用用途によってgemの組み合わせやバージョンを管理できるようになる仕組みのようです。
開発環境によって、組み合わせが変わったりできるとか。
次のサイトで、賢い使い方がわかりやすく載ってたので、使う場合は参考にすると良いかと。(参考サイト：rvm のgemsetをおさらい（Mac でRuby）)
とりあえず、heroku用のgemsetを作って見ましょうー。
以下のコマンドでOK。
rvm --create 1.9.3-p194@heroku-samplegemでherokuをインストールもしちゃいます。
$ gem install heroku --no-ri --no-rdoc

rails3.2.2をインストール
railsをインストールします。2012/09/17時点で、railsの最新が3.2.8だったので、それを入れてみます。
gem install rails --version 3.2.8 --no-ri --no-rdoc

migrationとは、Rubyスクリプトによって、テーブルの作成やカラムの構成変更を行う機能のこと。
詳しくは、次のサイトを参考にしてください。
(参考サイト：Ruby on Rails : migration 機能でデータベーススキーマを変更する)
それでは、メンテナンスモードに切り替えます。メンテナンスモードなので、エラーが表示されなくなります。
heroku maintenance:onherokuにdeployします。
git push heroku masterheroku側もmigrateします。
heroku run rake db:migrateメンテナンスモードを解除します。
heroku maintenance:offherokuを開いて確認
heroku openこんな画面が開いたらOK
herokuでアプリ公開まで出来ました！
