Faraday :: Connection在Devise :: SessionsController＃create中失败

时间：2019-05-05 03:41:15

标签： ruby-on-rails

直到几分钟前，我的应用程序都运行良好，出现以下错误：

Faraday::ConnectionFailed in Devise::SessionsController#create
Failed to open TCP connection to localhost:9200 (Connection refused - connect(2) for "localhost" port 9200)

我尝试搜索，发现这可能与弹性搜索有关。所以我做了以下事情：

$ curl localhost:9200
curl: (7) Failed to connect to localhost port 9200: Connection refused

$ brew services start elasticsearch
Service `elasticsearch` already started, use `brew services restart elasticsearch` to restart.

什么都没有改变，仍然没有用。

我猜可能有多个问题的来源。有人知道如何调查并修复此问题吗？ 该应用程序的其余部分运行良好，但是与模型中的搜索踢有关的所有问题都会造成该问题。

以下是来自控制台的日志：

我刚尝试为表重新索引：

Faraday::ConnectionFailed (Failed to open TCP connection to localhost:9200 (Connection refused - connect(2) for "localhost" port 9200))

我只是通过搜索发现它可能与内存有关。不确定如何检查它，该应用程序也可以在HEROKU上正常运行，因此问题是本地的，但我必须确定要修复。

（已编辑问题） 我只是从终端运行了elasticsearch，它返回以下内容：

运行elasticsearch时出现以下错误

ERROR: Cluster name [elasticsearch_etiennelandro] subdirectory exists in data paths [/usr/local/var/lib/elasticsearch/elasticsearch_etiennelandro]. All data under these paths must be moved up one directory to paths [/usr/local/var/lib/elasticsearch]

如xeraa中的this post所述

  

您之前是否安装了旧版本（2.x或更早版本）？听起来很像这个PR to check that you're not using the old behavior when there was the node name in the path。

     

我会做什么：

     
      

  • 如果您不再需要数据，只需删除   / usr / local / var / lib / elasticsearch / elasticsearch_nikitavlasenko和   重新开始。

    •   

  • 如果需要数据，则可以在您的计算机中更改path.data   配置或上移文件夹（就像日志消息一样）   说）。

    •   
     

PS：我不会将端口9300用于HTTP，因为通常这是用于集群本身中节点通信的端口。

还考虑阅读该页面上的评论和相关帖子，例如Franz Kafka

中的评论和相关帖子
  

事实证明，该配置文件指向/ usr / local / var / lib / elasticsearch以获取数据路径，但是该软件包创建了目录/ usr / local / var / lib / elasticsearch / elasticsearch_USERNAME。由于该目录位于其中，因此无法启动。我只需按照您的建议删除elasticsearch_USERNAME目录即可解决该错误。

该错误使您的elastichsearch服务器崩溃，该服务器应在localhost:9200上运行
