django - Elasticsearch端口9300 Django

Question

我遇到了一个奇怪的问题，使用 Django Haystack 和 ElasticSearch ，所以我无法rebuild_index。

ElasticSearch在机器上正确运行:

$ 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"
}

但这是ElasticSearch的日志:

我使用此tutorial安装了JAVA和Elastisearch

我的应用在Google Compute Engine中运行

如果有人可以帮助我。

我的设置:

Answer 1

我认为您的settings.py文件中有错字:您正在尝试在端口9200上运行elasticsearch时连接到端口9300:

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

如果这样不能解决问题，您可以发布settings.py文件的相关部分吗？

编辑
查看一些相关的帖子，看来节点之间可以通过端口9300以及端口9200相互通信。您的ping也可以在端口9300上工作吗？如果没有，那可能还需要开放。
