上記サイトを参考にchefを触ってたら、以下のコマンドでエラーが出た。

knife solo cook centos

epelが見つからないらしい。
ノードの設定を以下のように変更。

nodes/centos.json

  "run_list": [
      "yum",
      "nginx"
  ],

リトライ。

調べたところ以下の手順でインストール可能らしい。
cookbook v3.0からの変更みたい。

knife cookbook create nginx -o site-cookbooks/
vim site-cookbooks/nginx/recipes/default.rb

defaul.rb

# add the EPEL repo
yum_repository 'epel' do
  description 'Extra Packages for Enterprise Linux'
  mirrorlist 'http://mirrors.fedoraproject.org/mirrorlist?repo=epel-6&arch=$basearch'
  fastestmirror_enabled true
  gpgkey 'http://dl.fedoraproject.org/pub/epel/RPM-GPG-KEY-EPEL-6'
  action :create
end

package "nginx" do
  action [:install]
end

knife solo cook centos

エラーがなくなり成功。

以下のコマンドでインストールされていることを確認。

ssh centos
nginx -v
