Elasticsearch端口9300 django

Question

我面临着一个奇怪的问题，使用Django Haystack和ElasticSearch，所以我不能使用rebuild_index。

ElasticSearch在机器上正常运行：

$ curl -X GET 'http://localhost:9200'
{
  "status" : 200,
  "name" : "Ziggy Pig",
  "cluster_name" : "elasticsearch",
  "version" : {
  "number" : "1.7.2",
  "build_hash" : "e43676b1385b8125d647f593f7202acbd816e8ec",
  "build_timestamp" : "2015-09-14T09:49:53Z",
  "build_snapshot" : false,
  "lucene_version" : "4.10.4"
  },
  "tagline" : "You Know, for Search"
}

但是这是ElasticSearch的日志：

我用这个教程安装了JAVA和El154搜索。

我在上运行的应用程序

如果有人能帮我的话。

我认为您的settings.py文件中有一个错误:当elasticsearch在端口9200上运行时，您试图连接到端口9300：

Caused by: java.net.ConnectException: Connection refused: /10.142.0.2:9300

如果settings.py文件的相关部分不能解决问题，您可以将其发布吗？

编辑浏览了一些相关文章，似乎节点通过端口9300和端口9200相互通信。您的ping也在9300端口工作吗？如果没有，这也可能需要开放。
