我已经在我的rails应用程序中添加了elasticsearch，我也在我的Gemfile中包含了这些宝石：
gem "elasticsearch-rails"
gem "elasticsearch-model"
gem 'ngram'
一切正常，但每次重新启动电脑时都会收到此错误信息
Faraday::ConnectionFailed Connection refused - connect(2) for "localhost" port 9200
每次我需要重新安装eleasticsearch才能使其正常工作。
我在其他帖子中看到某些人/etc/init.d/elasticsearch restart
解决问题但不适合我。我正在使用Ubuntu。
有什么建议吗？

这可能是因为启动PC时Elasticsearch服务器无法自动启动。
如果您安装Elasticsearch服务器as a service并正确配置，问题就会消失。
