尝试在 Vagrant vm 上启动 rails 服务器时出错答案

【问题标题】：Getting error trying to start rails server on Vagrant vm尝试在 Vagrant vm 上启动 rails 服务器时出错
【发布时间】：2014-07-28 18:25:09
【问题描述】：

下面是我在 vagrant VM 上尝试运行“rails s”时收到的控制台错误消息。它退出所有这些错误消息，第一行是 /home/vagrant/.rvm/rubies/ruby-2.0.0-p247/lib/ruby/2.0.0/net/http.rb:878:in `initialize': 连接被拒绝-connect(2) (Errno:: ECONNREFUSED）

不知道这里发生了什么......

非常感谢

config\initializers\tire.rb 子域 = ""

if Rails.env.alpha?
  subdomain = ".alpha."
end

if Rails.env.development?
  Tire.configure { logger 'log/elasticsearch_development.log', :level => 'debug' }
else
  Tire.configure { logger "log/elasticsearch.#{Rails.env.to_s.downcase}.log" }
end

prefix = "org.#{Rails.application.class.parent_name.downcase}#{subdomain}_#{Rails.env.to_s.downcase}"
Tire::Model::Search.index_prefix(prefix)


def get_indices_for_env(prefix)
  aliases = Tire::Configuration.client.get(Tire::Configuration.url + '/_aliases').body
  global_indices = MultiJson.load(aliases).keys

  all_indices = global_indices.select do |index|
    index.start_with? prefix
  end
  all_indices.freeze
end

ALL_INDICES = get_indices_for_env(prefix)

【问题讨论】：

看看代码：'config/initializers/tire.rb:20' 基于它发出http请求并失败的错误
@house9 感谢 house9，我用 config/initializers/tire.rb 中的 ruby 文件编辑了原始帖子，但不确定问题出在哪里……我看到这个 Rails 项目是为了第一次，通过 Vagrant 从别人那里传下来。
先注释掉那个文件，看看能不能启动rails
@house9 谢谢，评论了那个愚蠢的文件有效，但现在我有另一个问题......也许我可以在另一个问题上处理它，但你对此有任何想法吗？ Rails 服务器显示错误：ActiveRecord::StatementInvalid in PostsController#homepage Mysql2::Error: Unknown column 'posts.status' in 'where clause': SELECT posts.* FROM posts WHERE posts。 status = 'PUBLISHED' AND posts.post_type = 'About' AND (title LIKE 'About Ourgoods%') ORDER BY created_at DESC LIMIT 1.... 我在 *.sql 文件中有数据库快照，所以我想我必须把它挂起来
@house9 没关系，我想通了，谢谢！！！！

【解决方案1】：

就像上面评论的house9一样，我基本上注释掉了导致我出现问题的整个ruby文件。

然后我在启动 Rails 服务器时遇到了问题，因为它找不到数据库。所以它抛出了一个 ActiveRecord 错误：

ActiveRecord::StatementInvalid in PostsController#homepage Mysql2::Error：'where 子句'中的未知列'posts.status'：SELECT posts.* FROM posts WHERE posts.status = 'PUBLISHED' AND posts.post_type = 'About' AND (title LIKE 'About Ourgoods%') ORDER BY created_at DESC LIMIT 1....

在将我必须的 .sql 文件连接到 Rails 应用程序（按照来自：How do I connect a mysql database file to a local ruby on rails application 的说明）并运行 rake db:migrate 后，我终于让 rails s 工作了！
