IT練習ノート

IT関連で調べたこと（実際は嵌ったこと）を書いています。

chefでhello world

chef

今回も嵌りました。単純にログでHello Chef!を出力したかったのですが、出来ず。あとruby覚えるのが辛い。

参考にさせて頂いた資料

環境

AMI ID RHEL-6.5_GA-x86_64-7-Hourly2 (ami-a15e24a0)

chefインストール前の準備

treeコマンドが入ってなかったのでインストール

[user]# yum install tree

chefインストールをします。

オプションのLの意味は下記です。

 -L/--location      Follow Location: hints (H)
    --location-trusted Follow Location: and send auth to other hosts (H)
