SocketError(getaddrinfo:名称或服务未知) - Sunspot/Solr Rails开发

Question

使用Passenger,Capistrano,nginx和MySQL将我的rails 3.0.10应用程序部署到Ubuntu 10.04服务器时遇到了很多麻烦(而apache2则更麻烦).将rake降级到0.8.7之后它终于正常工作,但现在Sunspot/Solr在我的开发环境中不起作用.sunspot_solr服务器正在运行,我可以获取服务器的URL,并通过浏览器连接到它.该网址与sunspot.yml中的网址相同.我不知道我做了什么导致了这个问题.我之前遇到过与太阳黑子相同的问题(在降级rake之前).然后它突然又开始工作了.我不知道为什么......我试过两个版本的太阳黑子(1.2.1和1.3.0).两者都提前工作,但现在不再工作了.

这是我收到的错误消息:

SocketError (getaddrinfo: Name or service not known):
app/models/resource.rb:128:in `text_search'
app/controllers/search_controller.rb:21:in `index'

Rendered /usr/lib/ruby/gems/1.8/gems/actionpack-3.0.10/lib/action_dispatch/middleware/templates/rescues/_trace.erb (2.0ms)
Rendered /usr/lib/ruby/gems/1.8/gems/actionpack-3.0.10/lib/action_dispatch/middleware/templates/rescues/_request_and_response.erb (161.6ms)
Rendered /usr/lib/ruby/gems/1.8/gems/actionpack-3.0.10/lib/action_dispatch/middleware/templates/rescues/diagnostics.erb within rescues/layout (168.9ms)

控制器有点乱,所以我只包括相关部分:

@criterion = params[:criterion]
@sort_direction = params[:sort_direction]
if @criterion && @sort_direction
  session["sort_search"] = @criterion + "|" + @sort_direction 
elsif session["sort_search"]
  @criterion = session["sort_search"].split("|")[0]
  @sort_direction = session["sort_search"].split("|")[1]
else
  @criterion = "updated_at"
  @sort_direction = "desc"
 end
@search = Resource.text_search(session[:search_params] || "", current_user, @criterion, @sort_direction) 
@resources = @search.results

我没有更改控制器中的任何内容,因为它正在工作.

我的gemfile:

source 'http://rubygems.org'
gem 'rake'
gem 'rails', '3.0.10'
gem 'jquery-rails', '>= 1.0.12'
gem 'sqlite3'
gem 'ancestry'
gem 'carrierwave'
gem 'sunspot_rails', '>= 1.3' #'~> 1.2.1' #
gem 'authlogic'
gem 'will_paginate'
gem 'declarative_authorization'
group :production do
  gem 'mysql'
end
group :development do
  gem 'sunspot_solr'
end
gem 'capistrano'

我的rakefile:

require File.expand_path('../config/application', __FILE__)
require 'rake'

Skolearkivet::Application.load_tasks

Answer 1

只是一个疯狂的猜测,你有没有机会使用localhost作为主机名？尝试将localhost更改为127.0.0.1

Answer 2

我将此行添加到文件app/controllers/search_controller.rb的顶部

require 'resolv-replace'

或者您也可以将它放到initializers/requires.rb中
