我将我的应用程序推向生产并遇到弹性搜索连接问题。当我通过 SSH 连接到我的服务器并尝试重新索引（或使用 Elasticsearch 执行任何操作）时，我收到以下错误：
deploy@living-recipe-server-01:~/living-recipe/current$ bundle exec rails searchkick:reindex CLASS=Recipe --trace
** Invoke searchkick:reindex (first_time)
** Invoke environment (first_time)
** Execute environment

我知道 Elasticsearch 的连接很好，因为当我运行 curl 命令检查端口时，我得到以下信息
{
"name" : "living-recipe-elasticsearch",
"cluster_name" : "elasticsearch",
"cluster_uuid" : "_na_",
"version" : {
"number" : "7.5.1",
"build_flavor" : "default",
"build_type" : "deb",
"build_hash" : "3ae9ac9a93c95bd0cdc054951cf95d88e1e18d96",
"build_date" : "2019-12-16T22:57:37.835892Z",
"build_snapshot" : false,
"lucene_version" : "8.3.0",
"minimum_wire_compatibility_version" : "6.8.0",
"minimum_index_compatibility_version" : "6.0.0-beta1"
},
"tagline" : "You Know, for Search"
}
我刚刚获得了基本的 searchkick 配置，并且在我的开发机器上一切正常。这是我的 elasticsearch.rb 初始化程序：
require "faraday"
require "typhoeus/adapters/faraday"
Searchkick.timeout = 90
Searchkick.client.transport.logger = Logger.new(STDOUT)
ENV["ELASTICSEARCH_URL"] = "http://xx.xxx.xxx.xxx:9200"
这一直困扰着我，不知道此时还能尝试什么
编辑：所以在我的服务器上卸载并重新安装弹性搜索。这是一个新的部署。当我查看日志时，这是输出：
