ruby-on-rails - 轮胎/ Elasticsearch 远程服务器连接错误

Question

我已经安装了带有 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

我得到 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:

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"
}

我可以重新启动、启动和停止 elasticearhc 服务器。

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

我在 config/initializer/ 文件夹中有一个 tire.rb 文件，其中包含以下代码:

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

这是我重建索引的 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，所以在重建索引之前我没有进行迁移。

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] [IMPORT] Deleting index 'cvs'
 ** [out :: 111.111.111.111] 
 ** [out :: 111.111.111.111] rake aborted!
 ** [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并且我已经尝试过:

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

我得到了相同的结果:

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 tire/rails 应用和我的 elasticsearch 服务器之间的连接？

Answer 1

我认为你的 config/initializers/tire.rb 中的语法有误，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
