○環境
CentOS 5.2
○手順
Rubyのインストール
Gemsのインストール。
Gemsは標準のCentOSのレポジトリには入ってないので、dlutterというレポジトリを追加
/etc/yum.repos.d/dlutter.repo というファイルを以下の内容で作成。
name=Unsupported RHEL5 packages (dlutter)
baseurl=http://people.redhat.com/dlutter/yum/rhel/5/$basearch/
enabled=0
gpgcheck=0
いよいよGemsのインストール。
Loading "fastestmirror" plugin
Loading mirror speeds from cached hostfile
* dlutter: people.redhat.com
* base: dist1.800hosting.com
* updates: centos-distro.cavecreek.net
* addons: mirror.steadfast.net
* extras: mirror.unl.edu
