【问题描述】：

我已经完成了我的应用程序，我正在尝试检查生产环境。该应用程序使用 sunspot_rails gem 进行搜索。它在开发服务器上运行良好，但在生产环境中不起作用。我的生产日志提供以下内容：

Errno::ECONNREFUSED (Connection refused -        {:data=>"fq=type%3AArticle&start=0&rows=1&q=%2A%3A%2A", :method=>:post, :params=>{:wt=>:ruby}, :query=>"wt=ruby", :headers=>{"Content-Type"=>"application/x-www-form-urlencoded; charset=UTF-8"}, :path=>"select", :uri=>#<URI::HTTP:0x007ff38e350578 URL:http://localhost:8983/solr/production/select?wt=ruby>, :open_timeout=>nil, :read_timeout=>nil, :retry_503=>nil, :retry_after_limit=>nil}):
app/controllers/articles_controller.rb:12:in `index'

我该如何解决这个问题？

这是我的articles_controller：

    class ArticlesController < ApplicationController
  before_filter :require_login, except: [:show, :index]
 def index
  @search = Article.search do
  fulltext params[:search]
  paginate :page => params[:page], :per_page => 1
  end
    @articles = @search.results 
  #@articles_by_month = Article.find(:all).group_by { |post| post.created_at.strftime("%B") }
 end
def show
  @article = Article.find(params[:id])
  @comment = Comment.new
 @comment.article_id = @article.id
end
def new
 @article = Article.new
end
def create
 @article = Article.new(article_params)
 @article.save
 redirect_to article_path(@article)
end
def edit
 @article = Article.find(params[:id])
end
def destroy
 @article = Article.find(params[:id])
 @article.destroy
 redirect_to articles_path
end
def update
 @article = Article.find(params[:id])
 @article.update(article_params)
 flash.notice = "Article '#{@article.title}' Updated!"
 redirect_to article_path(@article)
end
def article_params
 params.require(:article).permit(:title, :body, :tag_list, :picture)
end
end

这是我的 Gemfile：

ruby '2.0.0'

end

我该如何解决这个问题？

【问题讨论】：

标签： ruby-on-rails production-environment sunspot-solr

【解决方案1】：

您是否在生产服务器中启动了 solr 实例？

bundle exec sunspot-solr start -p 8983

【讨论】：

【解决方案2】：

我过去曾用 Solr 处理过一些类似的问题。我做了一个script 来为我处理启动它。它确保清理任何可能影响访问的粗劣文件。

希望对您有所帮助！

见下文：

pkill -f solr

#remove old data
rm -rf solr/data
rm -rf solr/default
rm -rf solr/development
rm -rf solr/pids
rm -rf solr/test

while getopts 'pdt' flag; do
  case "${flag}" in
    d) export RAILS_ENV=development ;;
    p) export RAILS_ENV=production ;;
    t) export RAILS_ENV=test ;;
    *) error "Unexpected option ${flag}" ;;
  esac
done

#startup solr
bundle exec rake sunspot:solr:start

echo "Solr started successfully."
