设置searchkick

Question

我正试着在c9.io上设置searchkick。我已经安装了elasticsearch，但是我无法访问localhost或c9.io在端口9200上提供给我的URL，以验证searchkick是否正常工作。有没有人遇到过这个问题？

我已经验证了elasticsearch正在工作。

$ /home/ubuntu/.linuxbrew/bin/brew info elasticsearch
elasticsearch: stable 1.7.1, HEAD
Distributed real-time search & analytics engine for the cloud
https://www.elastic.co/products/elasticsearch
/home/ubuntu/.linuxbrew/Cellar/elasticsearch/1.7.1 (33 files, 30M) *
  Built from source

Logs:    /home/ubuntu/.linuxbrew/var/log/elasticsearch/elasticsearch_ubuntu.log
Plugins: /home/ubuntu/.linuxbrew/var/lib/elasticsearch/plugins/
Config:  /home/ubuntu/.linuxbrew/etc/elasticsearch/

当我运行rake时，这是我得到的错误消息。

$rake searchkick:reindex CLASS=Account
rake aborted!

/usr/local/rvm/gems/ruby-2.1.5@rails4/gems/faraday-0.9.1/lib/faraday/connection.rb:377:in `run_request'
ect...

我在想，如果我不能找到这个问题的解决方案，我会建立一个本地环境，但我真的不想这样做。

我在我的mac上运行时也遇到了类似的问题。由于您安装的版本不会自动作为守护程序运行，因此连接将被拒绝。如果你运行的是ubuntu，最好安装这个包。elasticsearch网站上有一个简单易读的指南。使用下面网站上的步骤，再给它一次机会。

Answer 2

我还没有安装searchkick，但我一直在C9环境中开发ElasticSearch。

以下是我所做的步骤：

wget https://download.elasticsearch.org/elasticsearch/release/org/elasticsearch/distribution/deb/elasticsearch/2.2.0/elasticsearch-2.2.0.deb

sudo dpkg -i elasticsearch-2.2.0.deb

sudo update-rc.d elasticsearch defaults 95 10

sudo /etc/init.d/elasticsearch start

然后，我修改了elasticsearch.yml文件，使其包含c9.io支持的端口(例如，8081或8082 )：取消文件中主机端口的注释，并修改这个端口号。

sudo nano /etc/elasticsearch/elasticsearch.yml  

最后，创建一个elasticsearch初始化器(配置/初始化/弹性搜索.rb)，并包含c9 IP：

"Your Model to be indexed".__elasticsearch__.client = Elasticsearch::Client.new host: ENV['IP']

希望这能有所帮助，因为C9环境下的elasticsearch的端口问题还没有很好的文档记录。
