生产中的 Searchkick + ElasticSearch：Faraday::ConnectionFailed：连接被拒绝 - connect(2)

Question

我有一个使用 ElasticSearch 进行生产的应用程序。（它有效）但现在我可以添加 searchkick gem 而不是只使用 elasticsearch。

为此，我添加了以下内容：

在我的Gemfile 中添加：

gem 'elasticsearch-model'
gem 'elasticsearch-rails'
gem 'searchkick'

在我的config/initializers/elasticsearch.rb（我使用 Amazon Elasticsearch Service 进行生产。好的，我知道这是不好的做法，但我会为环境变量更改此设置）

if Rails.env == "production"
    Elasticsearch::Model.client = Elasticsearch::Client.new url: 'https://xxxxxxxx.xxxxxxx.amazonaws.com/'

else
    Elasticsearch::Model.client = Elasticsearch::Client.new url: 'http://localhost:9200/'
end

在模型/product.rb

require 'elasticsearch/model'

class Product < ActiveRecord::Base
  include Elasticsearch::Model
  include Elasticsearch::Model::Callbacks
  searchkick
  #currently use this function for search. (It works)
  scope :searching, ->(query) { __elasticsearch__.search(query).records }
end

但是现在当我尝试在服务器中使用时：

Product.search("foobar") #before run: rails c production 

显示下一条消息：Faraday::ConnectionFailed：连接被拒绝 - connect(2)

之后我试试这个

rake searchkick:reindex:all RAILS_ENV=production

我收到了同样的信息。对此有什么想法吗？

写完这篇文章后，我读到了：带有 ElasticSearch 的 Searchkick 返回“Faraday::ConnectionFailed: execution expired”

在config/initializers/elasticsearch.rb

if Rails.env == "production"
  url = 'http://myelasticsearch-xyz-foobar.amazonaws.com'
    Elasticsearch::Model.client = Elasticsearch::Client.new url: url
  Searchkick.client = Elasticsearch::Client.new(hosts: url, retry_on_failure: true, transport_options: {request: {timeout: 250}})
else
  url = 'http://localhost:9200/'
    Elasticsearch::Model.client = Elasticsearch::Client.new url: url
  Searchkick.client = Elasticsearch::Client.new(hosts: url, retry_on_failure: true, transport_options: {request: {timeout: 250}})
end

重构并清理这段代码后，我得到了这个：

  Elasticsearch::Model.client = Elasticsearch::Client.new url: env['RAILS_ENV']
  Searchkick.client = Elasticsearch::Client.new(hosts: env['RAILS_ENV'], retry_on_failure: true, transport_options: {request: {timeout: 250} })

我希望这个解释对其他人有用
