Question

我已安装了带有elasticsearch的ubuntu 12.04远程服务器。

我已经安装了elasticsearch：

sudo apt-get update
sudo apt-get install openjdk-7-jre-headless -y
wget https://download.elasticsearch.org/elasticsearch/elasticsearch/elasticsearch-0.20.6.deb
sudo dpkg -i elasticsearch-0.20.6.deb
sudo service elasticsearch start

我选择sudo elasticsearch status：

* ElasticSearch Server is running with pid 2483

我的elasticsearch远程服务器工作正常：

ubuntu12@juan:~/Escritorio/myapp$ curl http:/111.111.111.111:9200
{
  "ok" : true,
  "status" : 200,
  "name" : "Hogan, Harold \"Happy\"",
  "version" : {
    "number" : "0.20.6",
    "snapshot_build" : false
  },
  "tagline" : "You Know, for Search"
}

或使用我的子域名：

ubuntu12@juan:~/Escritorio/myapp$ curl http://elasticsearchserver.mydomain.com:9200
{
  "ok" : true,
  "status" : 200,
  "name" : "Hogan, Harold \"Happy\"",
  "version" : {
    "number" : "0.20.6",
    "snapshot_build" : false
  },
 "tagline" : "You Know, for Search"
}

我可以重启，启动和停止elasticsearhc服务器。

sudo service elasticsearch restart
 * Stopping ElasticSearch Server                                                                                                                                                                      [ OK ] 
 * Starting ElasticSearch Server                                                                                                                                                                      [ OK ]

我在tire.rb文件夹中有一个config/initializer/文件，其中包含下一个代码：

if Rails.env == 'production'
  Tire.configure do
    url "http://elasticsearchserver.mydomain.com:9200"
  end
end

这是重新索引的capistrano任务：

after "deploy:finalize_update", "deploy:elasticsearch:index_classes"
namespace :deploy do
  namespace :elasticsearch do
   desc 'run elasticsearch indexing via tire'
    task :index_classes do
      run "cd #{deploy_to}/current && bundle exec rake environment tire:import CLASS=Object FORCE=true "
    end
  end
 end

我使用mongodb作为数据库，所以我没有在重建索引之前进行迁移。

这是capistrano错误：

2013-04-06 14:25:50 executing `deploy:elasticsearch:index_classes'
 #
 #
 ** [out :: 111.111.111.111] Skipping index creation, cannot connect to Elasticsearch
 ** [out :: 111.111.111.111] 
 ** [out :: 111.111.111.111] (The original exception was: #<Errno::ECONNREFUSED: Connection refused - connect(2)>)
 ** [out :: 111.111.111.111]

 ** [out :: 111.111.111.111] Connection refused - connect(2)
 ** [out :: 111.111.111.111]
 #

我已经将tire.rb文件上传到生产服务器，我尝试过：

bundle exec rake environment tire:import CLASS=Object FORCE=true

我得到了同样的结果：

Skipping index creation, cannot connect to Elasticsearch
(The original exception was: #<Errno::ECONNREFUSED: Connection refused - connect(2)>)
[IMPORT] Deleting index objects'
rake aborted!
Connection refused - connect(2)

我做错了什么？如何修复轮胎/轨道应用程序与弹性搜索服务器之间的连接？

Answer 1

我认为你的config / initializers / tire.rb中的语法错误，见下文

Tire.configure do
  url "http://localhost:9200"
  #you can uncomment the next line if you want to see the elasticsearch queries in their own seperate log
  #logger "#{Rails.root}/log/es.log" 
end

Answer 2

这是tire.rb文件

内部正常工作的语法

require 'tire'
Tire.configure { url "http://myremoteserver.com:9200" }

现在它工作正常！

谢谢！
