VirtualBoxに苦戦

（Windows版での対応は⇒VirtualBoxに苦戦 (2)）

MVCを試そうとしてどうにもしっくりこないCakePHPにちょっと見切りをつけ、やっと記法にもなじんできたRubyでということで、本丸的な「Ruby on Rails」を試すことに。

参考本で、VirtualBoxで動かすようにしていたので真似てそちらを試そうとしたら、長き道のりの始まりだった…。

CentOS-6.5 x86_64の環境（↓）に：

$ cat /etc/issue; uname -a; cat /proc/cpuinfo | grep flags | uniq
CentOS release 6.5 (Final)

下記リンクからCentOS-6 AMD64用のVirtualBoxを入手し、インストール：

これはこれで動作するようなんだが、Vagrantでのprovisionがうまくいかない：

SSH connection was refused! This usually happens if the VM failed to
boot properly. Some steps to try to fix this: First, try reloading your
VM with `vagrant reload`, since a simple restart sometimes fixes things.
If that doesn't work, destroy your VM and recreate it with a `vagrant destroy`
followed by a `vagrant up`. If that doesn't work, contact a Vagrant
maintainer (support channels listed on the website) for more assistance.

何度やってもこのあたりで止まってしまう（始めのうちは、vagrant upの失敗後にもう一度試すとそのまま動作するので正しいのかと思っていたら、Vagrantの動作が変更になって、明示的に指定しないと再provisionをしないことになっていただけだった）。

SELinux関連で引っかかっているのか、ホスト側が64bit版だからなのかよくわからない。

って、確認するとSELinuxは「無効（Permissive）」になってたわ。

$ getenforce
Permissive

こちらは保留中。
