Serverspec (2/3) ：スタンドアロン環境へのServerspecインストール

スタンドアロン環境へServerspecへインストールしてみる。

資材のダウンロード

• Rubyのダウンロード
  RHEL同梱版ではServerspecのインストールでwarningが出るため最新版を導入する。
  以下からダウンロード、/tmpに格納
  Ruby 2.1.1
  https://www.ruby-lang.org/ja/
  

• RubyGemsのダウンロード
  以下からダウンロード、/tmpに格納
  RubyGems v2.2.2
  http://rubygems.org/pages/download
  

• Serverspecのダウンロード
  必要パッケージをダウンロード、/tmp/serverspecに格納。
  serverspec 1.0.0
  http://rubygems.org/gems/serverspec
  specinfra 1.0.1
  http://rubygems.org/gems/specinfra
  highline 1.6.21
  http://rubygems.org/gems/highline
  rspec 2.14.1
  http://rubygems.org/gems/rspec
  net-ssh 2.8.0
  http://rubygems.org/gems/net-ssh

Serverspecのインストール

Serverspecのインストール要件であるRubyとRubyGemsをインストールする。
1.Rubyのインストール

# cd /tmp
# tar zxvf ruby-2.1.1.tar.gz
# cd ruby-2.1.1
# ./configure 
# make
# make install

2.RubyGemsのインストール

# cd /tmp
# tar zxvf rubygems-2.2.2.tgz 
# cd rubygems-2.2.2
# ruby setup.rb 

3.Serverspecのインストール

# cd /tmp/serverspec
# gem install serverspec --local

もし以下のエラーが出た場合は追加手順が必要。

# gem install serverspec --local
ERROR:  Loading command: install (LoadError)
	cannot load such file -- zlib
ERROR:  While executing gem ... (NoMethodError)
    undefined method `invoke_with_build_args' for nil:NilClass

zlibをインストールしただけでは解決できなかったが、以下のコマンドで補えるらしい。

# cd /tmp/ruby-2.1.1/ext/zlib
# ruby extconf.rb
# make
# make install

コマンド実行後、再度Serverspecのインストールを行う。

お疲れ様でした。

Rdocに関するエラー。Rubyが古いと出るらしい。。。
