使用 Vagrant 和 Chef Solo 安装 mysql 食谱答案

【问题标题】：Install mysql cookbook with Vagrant and Chef Solo使用 Vagrant 和 Chef Solo 安装 mysql 食谱
【发布时间】：2015-03-13 09:50:21
【问题描述】：

我很难弄清楚如何安装 mysql 食谱 (https://supermarket.chef.io/cookbooks/mysql) 我已按照说明进行操作，但这是我第一次使用 Vagrant 和 Chef，安装配方时一直卡住

这是我的流浪文件： http://pastebin.com/9Fgts4J6

这是我的厨师文件（我使用图书管理员）： http://pastebin.com/EfxPrC9S

这是我的自定义配方“mysql_config”，位于 my_cookbooks/mysql_config/recipes/default.rb： http://pastebin.com/Zh5Y4z8b

这是我遇到的错误：

==> 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

这是我运行 vagrant up 时的控制台输出： http://pastebin.com/ekkhHHru

好像我遗漏了一些配置，但我不知道该放在哪个以及放在哪里，我已经搜索了教程，但是 mysql_cookbook 和 vagrant 最近变化很大，所以我找不到任何好的那些。对此的任何帮助将不胜感激

流浪文件：

Vagrant.configure(2) do |config|

  config.vm.synced_folder "../."

  config.vm.provision "shell" do |s|
    s.path = "provision/setup.sh"
  end

  config.vm.provision "chef_solo" do |chef|
    chef.cookbooks_path = ["./cookbooks", "./my_cookbooks"]
    chef.add_recipe "mysql_config"
    chef.json = {
      "mysql_config" => {
        "name" => "localhost"
      }
    }
  end

end

自定义配方：

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

我的控制台的输出：

【问题讨论】：

有人有想法吗？我已经在上面的问题中包含了代码
有人有机会看看这个吗？乍一看，这是某个地方的错误还是我在设置/工作流程中做错了什么？
我认为，但我真的不确定，您应该从 mysql_config 中删除源以保留默认模板（如果这是您希望的，我可能误解了）。错误在 config.name 可能资源没有正确设置，我不知道为什么。

【解决方案1】：

我也有同样的问题。我对 Chef 模板知之甚少，无法理解为什么没有设置 @config，但它绝对是 nil，这就是引发错误的原因。您甚至不能将源选项留空，因为 mysql 食谱会寻找一个不存在的 default.cnf.erb 并抛出一个稍微不同的错误。相反，您必须像 Ernie 所说的那样提供本质上是空的来源。

但是，你有一个完全空的 conf 文件，所以如果我们发现了这个，我们将不得不再次寻找它。相反，我这样做了：

<% 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 %>

所以现在我们没有收到错误，但是一旦我们弄清楚如何正确设置@config，我们就可以删除这个块并且它与 endblock 匹配

<% if !@config.nil? %>

继续前进！

如果我能弄清楚如何让@config 变量工作，我会更新这个答案。

【解决方案2】：

使用了来自灯具的配置文件： https://github.com/chef-cookbooks/mysql/tree/master/test/fixtures/cookbooks

现在可以了：

# /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 为空
