如何在新的Nitrous.io IDE上设置SearchKick / ElasticSearch？
我正在关注McKenzie Childs关于在Ruby on Rails上制作“电影评论”应用程序的教程，他正在使用searchkick gem。 我正在通过新的Nitrous平台做一切，一切都令人困惑。
我正在运行此命令：
rake searchkick:reindex CLASS=Movie 并在shell中出现以下错误：
rake aborted! Faraday::ConnectionFailed: Connection refused - connect(2) for "localhost"port 9200 /home/nitrous/code/12_in_12/movie_review/.bundle/gems/faraday-0.9.1/lib/faraday/adapter/net_http.rb:80:in `perform_request' /home/nitrous/code/12_in_12/movie_review/.bundle/gems/faraday-0.9.1/lib/faraday/adapter/net_http.rb:40:in `block in call' /home/nitrous/code/12_in_12/movie_review/.bundle/gems/faraday-0.9.1/lib/faraday/adapter/net_http.rb:87:in `with_net_http_connection' /home/nitrous/code/12_in_12/movie_review/.bundle/gems/faraday-0.9.1/lib/faraday/adapter/net_http.rb:32:in `call' /home/nitrous/code/12_in_12/movie_review/.bundle/gems/faraday-0.9.1/lib/faraday/rack_builder.rb:139:in `build_response' /home/nitrous/code/12_in_12/movie_review/.bundle/gems/faraday-0.9.1/lib/faraday/connection.rb:377:in `run_request' /home/nitrous/code/12_in_12/movie_review/.bundle/gems/elasticsearch-transport-1.0.12/lib/elasticsearch/transport/transport/http/faraday.rb:21:in `block in perform_request' /home/nitrous/code/12_in_12/movie_review/.bundle/gems/elasticsearch-transport-1.0.12/lib/elasticsearch/transport/transport/base.rb:190:in `call' Errno::ECONNREFUSED: Connection refused - connect(2) for "localhost" port 9200 /home/nitrous/code/12_in_12/movie_review/.bundle/gems/faraday-0.9.1/lib/faraday/adapter/net_http.rb:80:in `perform_request'
我有一种关于连接端口或启动服务器的感觉。 这是新的Nitrous Web IDE的第一个月。
昨天的教程是否遇到了同样的问题（使用的是cloud9 IDE）。 我注意到我收到了这个错误，因为弹性搜索没有运行。 我使用命令卸载它
sudo apt-get --purge autoremove elasticsearch
然后重新安装。
wget https://download.elasticsearch.org/elasticsearch/elasticsearch/elasticsearch-1.7.0.deb sudo dpkg -i elasticsearch-1.7.0.deb #enable on bootup sudo update-rc.d elasticsearch defaults 95 10 ### Start ElasticSearch sudo /etc/init.d/elasticsearch start ### Make sure service is running curl http://localhost:9200 ### Should return something like this: # { # "status" : 200, # "name" : "Storm", # "version" : { # "number" : "1.3.1", # "build_hash" : "2de6dc5268c32fb49b205233c138d93aaf772015", # "build_timestamp" : "2014-07-28T14:45:15Z", # "build_snapshot" : false, # "lucene_version" : "4.9" # }, # "tagline" : "You Know, for Search" #}
Searchkick在此之后工作。 您应该在安装弹性搜索之前安装java。 希望这对你有所帮助
