使用 Vagrant 和 Chef Solo 安装 MySQL Cookbook

Question

我很难弄清如何安装mysql cookbook (https://supermarket.chef.io/cookbooks/mysql)，我已经按照说明进行了操作，但这是我第一次使用Vagrant和Chef，而且在安装配方时一直卡住。

这是我的vagrant文件： http://pastebin.com/9Fgts4J6 这是我的Cheffile（我使用librarian）： http://pastebin.com/EfxPrC9S 这是我自定义的配方'mysql_config'，位于my_cookbooks/mysql_config/recipes/default.rb： http://pastebin.com/Zh5Y4z8b 这是我得到的错误：

==> 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 似乎缺少一些配置，但我不知道应该在哪里添加它们，我已经搜索了教程，但mysql_cookbook和vagrant最近发生了很多变化，所以我找不到好的教程。非常感谢您的帮助。

Vagrant 文件：

# -*- mode: ruby -*-
# vi: set ft=ruby :

Vagrant.configure(2) do |config|
  config.vm.box = "puphpet/debian75-x64"

  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

我的控制台输出：

有人有想法吗？我已经在问题中包含了代码。 - Ernie

有人有机会看一下这个吗？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？ - Ernie

我认为，但我真的不确定，你应该从mysql_config中删除源代码以保留默认模板（如果这是你想要的，我可能误解了）。错误在于config.name，也许资源没有正确设置它，我无法确定原因。 - Tensibai

Answer 1

我遇到了同样的问题。我对Chef模板化不太了解，无法理解为什么@config没有设置，但它绝对是nil，这就是报错的原因。你甚至不能将源选项留空，因为mysql cookbook会去寻找一个名为default.cnf.erb的文件，而这个文件并不存在，然后会抛出一个稍微不同的错误。相反，你必须像Ernie所说的那样给出一个基本为空的源。

但是，此时你得到的是完全空的配置文件，所以如果我们解决了这个问题，就需要再次查找。相反，我做了这个：

<% 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 %>

现在我们不会收到错误信息了，但是一旦我们能够正确设置@config，我们就可以删除这个块和它相应的endblock。

<% if !@config.nil? %>

并且我们可以开始了！

如果我能弄清楚如何让@config变量起作用，我会更新这个答案。

Answer 2

使用来自fixtures的配置文件： https://github.com/chef-cookbooks/mysql/tree/master/test/fixtures/cookbooks

现在它可以工作了：

# /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是空的
