我试图用Ruby on Rails在我的应用程序中添加Searchkick gem,但当我在搜索框中键入一个单词时,我的应用程序中出现了这个错误。我已经根据需要安装了elasticsearch和最新版本的java,但错误仍然是一样的。这就是我得到的错误: Faraday::PostsController搜索中的连接失败 连接被拒绝-为“localhost”端口9200连接(2) 这是我的密码: 终端显示已安装弹性搜索: 终端Ruby on rails 法拉第::连接失败,连接被拒绝-connect(2)for“;本地主机&x201D;端口9200错误Ruby on Rails,ruby-on-rails,ruby,ruby-on-rails-3,ruby-on-rails-4,

这是我得到的屏幕,错误如下:
看起来您的弹性搜索服务没有运行。你必须确保它正在运行
要查看弹性搜索服务是否正在运行,请运行:
curl localhost:9200
如果它正在运行,则应返回如下哈希值:
{
"status" : 200,
"name" : "Buzz",
"cluster_name" : "your_cluster_name",
"version" : {
"number" : "1.4.5",
"build_hash" : "...",
"build_timestamp" : "2015-04-27T08:06:06Z",
"build_snapshot" : false,
"lucene_version" : "4.10.4"
},
"tagline" : "You Know, for Search"
}
如果弹性搜索没有运行(这很可能是您的情况),请使用以下命令启动它:
sudo service elasticsearch start
这应该可以解决您的问题。
sudo服务弹性搜索开始
给我消息“sudo:service:command not found”
sudo service elasticsearch start
