以下、 CentOS7 に ruby 2.0.0-p481 をインストールした記録
もともと他の用途でセットアップしてあって、初期状態じゃないです
あと、 CentOS7 だけど sudo できるようにしてある
rbenv はインストール済みでした
作業開始
とりあえずインストールしてみる

もう一度

今度は yum しろって言われました
[shun ~]$ sudo yum install openssl-devel readline-devel zlib-devel
今度こそ

インストールされました
bundler がインストールされるのは rbenv-default-gems 使ってるからです
確認
[shun ~]$ ruby -v rbenv: ruby: command not found The `ruby' command exists in these Ruby versions: 2.0.0-p481
おや？
そうか。 ruby-version がなかった
[shun ~]$ cd work/ [shun work]$ ruby -v ruby 2.0.0p481 (2014-05-08 revision 45883) [x86_64-linux]
完了です
