VagrantとChef Soloを使ってmysql料理ブックをインストール

Question

mysql料理をインストールする方法を理解するのに本当に苦労しています（https://supermarket.chef.io/cookbooks/mysql） 私は指示に従ってきましたが、これはVagrantとChefを使うのは初めてです。これは位置私のカスタムレシピ「mysql_configを」です http://pastebin.com/EfxPrC9S

： http://pastebin.com/9Fgts4J6

これは私のcheffile（私は司書使用）です：維持はレシピ

をインストールしている間、これは私の浮浪者ファイルです立ち往生my_cookbooks/mysql_configを/レシピ/ default.rbに： http://pastebin.com/Zh5Y4z8b

これは私が取得していますエラーです：

==> default: ================================================================================ 
==> default: Error executing action `create` on resource 'template[default :create /etc/mysql-default/conf.d/default.cnf]' 
==> default: ================================================================================ 
==> default: 
==> default: Chef::Mixin::Template::TemplateError 
==> default: ------------------------------------ 
==> default: undefined method `name' for nil:NilClass 

放浪を実行するときに、これは私のコンソール出力です： http://pastebin.com/ekkhHHru

私はいくつかの設定が不足しているようですが、どの場所に置くべきかわからないので、私はチュートリアルを探しましたが、mysql_cookbookと迷惑メールは最近変更されてしまいました。

カスタムレシピ：：私のコンソールの

mysql_service 'default' do 
    port '3306' 
    version '5.5' 
    name 'localhost' 
    initial_root_password 'p4ssw0rd' 
    action [:create, :start] 
end 

mysql_config 'default' do 
    source 'my.cnf.erb' 
    notifies :restart, 'mysql_service[default]' 
    action :create 
end

ベイグラントファイルをいただければ幸いです備品： https://github.com/chef-cookbooks/mysql/tree/master/test/fixtures/cookbooks

今では動作します：

# /my_cookbooks/mysql_config/recipes/default.rb 

mysql_service 'default' do 
    version '5.5' 
    action [:create, :start] 
end 

mysql_config 'hello' do 
    instance 'default' 
    source 'hello.conf.erb' 
    version '5.5' 
    action :create 
end 

hello.conf.erbは、私は同じ問題を抱えている空

Answer 2

です。 @configが設定されていない理由を理解するためにシェフのテンプレートについて十分に知りませんが、間違いなく、エラーを投げているのは間違いです。 mysql cookbookは存在しないdefault.cnf.erbを探してわずかに異なるエラーを投げるので、ソースオプションを空白のままにすることはできません。代わりに、アーニーが言ったように、あなたは本質的に空のソースを与えなければならない。

しかし、あなたは完全に空のconfファイルを持っているので、これを理解するには、もう一度それを探す必要があります。代わりに、私はこれをしなかった：

<% if !@config.nil? %> 

    <% if @config.name %># Chef generated my.cnf for instance mysql-<%= @config.name %><% end %> 
    [client] 
    default-character-set   = <%= @config.charset %> 
    <% end %> 
    <% if @config.port %> 
    port       = <%= @config.port %> 
    <% end %> 
    <% if @socket_file %> 
    socket       = <%= @socket_file %> 
    <% end %> 

    [mysql] 
    <% if @config.charset %> 
    default-character-set   = <%= @config.charset %> 
    <% end %> 

    [mysqld] 
    <% if @config.run_user %> 
    user       = <%= @config.run_user %> 
    <% end %> 
    <% if @pid_file %> 
    pid-file      = <%= @pid_file %> 
    <% end %> 
    <% if @socket_file %> 
    socket       = <%= @socket_file %> 
    <% end %> 
    <% if @config.bind_address %> 
    bind-address     = <%= @config.bind_address %> 
    <% end %> 
    <% if @config.port %> 
    port       = <%= @config.port %> 
    <% end %> 
    <% if @data_dir %> 
    datadir      = <%= @data_dir %> 
    <% end %> 
    <% if @tmp_dir %> 
    tmpdir       = <%= @tmp_dir %> 
    <% end %> 
    <% if @lc_messages_dir %> 
    lc-messages-dir    = <%= @lc_messages_dir %> 
    <% end %> 
    <% if @error_log %> 
    log-error      = <%= @error_log %> 
    <% end %> 
    <% if @include_dir %> 
    !includedir <%= @include_dir %> 
    <% end %> 

    [mysqld_safe] 
    <% if @socket_file %> 
    socket       = <%= @socket_file %> 
    <% end %> 
<% end %> 

だから今、私たちはエラーを得ることはありませんが、できるだけ早く、我々は適切に@configを設定する方法を見つけ出すことができますように、我々はこのブロックを削除することができ、それが

<% if !@config.nil? %> 

を末端ブロックマッチングいます

となります。

@config変数を取得する方法を理解できれば、この回答を更新します。
