knife-soloが失敗して、成功するまでの長い道のり

Last updated at Posted at 2015-02-06

失敗メモです

久しぶりにchefでサーバーを構築しようとknife-soloをやったら、エラーの嵐でやっと解決できたので、その過程を残します。だれかの役に立てればと思います。

実行環境

OSX : 10.10.2(Yosemite)
ruby : ruby 2.1.3p242 (2014-09-19 revision 47630) [x86_64-darwin13.0]
chef : 12.0.0.rc.0
gem : 2.4.5

やりたいこと

単純にknife soloをコマンドで実行してchef-soloの準備をしたかった。

gemの準備

任意のディレクトリでbundlerを初期化

bundle init

続いて生成されたgemfileにgemを指定。knife-solo、berkshelfとサーバー構築のテストを行いたかったのでserverspecも追加。

gemfile
# A sample Gemfile
source "https://rubygems.org"

# gem "rails"
gem "knife-solo"
gem "berkshelf"
gem "serverspec"

bundlerをインストール。

bundle install --path=vendor/bundle

エラーなくインストールできたので、knife solo init .を実行。

knife solo init .

エラーで動かなかった。なぜじゃ。(；一_一)

エラー文言ffi-yajl/json_gem is deprecatedに注目
これでGoogleに検索かけると以下のページがヒット

[妥協]WindowsのCygwinでgem install knife-soloがffi-yajlのエラーでこける件

もっと調べてstackoverflowがヒット

YAJL internal error: attempted use of non-string object as key

stackoverflowにかかれていた通り、ffi-yajlというgemをバージョン1.2にしてバージョン1.3.1は消すようにした。

gem install ffi-yajl -v 1.2
gem uninstall ffi-yajl -v 1.3.1

実行してみる。

以前エラーが出る。
cannot load such file -- chef/encrypted_data_bag_item/check_encrypted (LoadError)
が解消されない。
(ffi-yajlとは別の問題だった！！)

cannot load such file -- chef/encrypted_data_bag_item/check_encrypted (LoadError)を潰す

最初パーミッションの問題と思って、lsしてみると、読み込もうとしているファイルの所有者がrootだった。
chownでユーザーを変える。
変えたが同じエラーになった。

残念。

調べるとこんなページが。
Certain knife operations result in exception on chef/encrypted_data_bag_item/check_encrypted #238
→chef DKのバージョンを上げてくれって書かれていた。
→chef DKって何？？
→Chef Development Kitらしい。
→Chef Development Kitでダウンロードする。

無事にインストールする。バージョンを確認

chef --version
Chef Development Kit Version: 0.4.0

が、エラーは解消されず。

そして、knife solo init .を実行！

knife solo init .
-bash: /opt/chefdk/bin/knife: No such file or directory

しかしだめ。
エラー解消されず。しかも、コマンドが認識されなくなってしまった。

やっとエラー解消

コマンドが認識されなくたった時の対処法を載せてくれている方がいた！
installしたはずなのにコマンドが見つからない時の対処法φ(・・*)

まず、knifeコマンドの場所を探す

locate knife | grep bin
satoutashinoAir:chef satoutakeshi$ locate knife | grep bin
/Users/satoutakeshi/.rbenv/versions/2.1.3/bin/knife
/Users/satoutakeshi/.rbenv/versions/2.1.3/lib/ruby/gems/2.1.0/gems/chef-11.16.2/bin/knife
/Users/satoutakeshi/.rbenv/versions/2.1.3/lib/ruby/gems/2.1.0/gems/chef-11.16.4/bin/knife
/Users/satoutakeshi/.rbenv/versions/2.1.3/lib/ruby/gems/2.1.0/gems/chef-12.0.0.rc.0/bin/knife
/Users/satoutakeshi/vagrant/unibo/vagrant-rails-chef/vendor/bundler/ruby/2.1.0/bin/knife
/Users/satoutakeshi/vagrant/unibo/vagrant-rails-chef/vendor/bundler/ruby/2.1.0/gems/chef-11.16.4/bin/knife

/Users/satoutakeshi/.rbenv/versions/2.1.3/bin/knife
がknifeコマンドの格納場所。
.bash_profileにここのパスを追加する。

vim ~/.bash_profile

で以下を追加。

% setenv PATH /Users/satoutakeshi/.rbenv/versions/2.1.3/bin:$PATH

.bash_profileを再読み込み

source ~/.bash_profile

そして、knife soloを実行！
そのまえに、最初の設定をしてなかったので、する。

knife configure
knife solo init .

行けた！
長かった。
