Django Elasticsearch问题：ConnectionError

我正在我的新社会中开发不同的web应用程序，每次我想使用Elasticsearch（版本6.3.2）时都会收到这个问题：

然后

我得到这个问题如下。我试着做：

curl -XGET http://localhost:9200

我得到以下信息：

curl:（7）无法连接到本地主机端口9200:Connexion refusée

你知道这件事吗？我得去什么地方

多谢各位

编辑：

在

/var/log/elasticsearch/elasticsearch.log

中，我遇到了一个循环问题：

问题在于ingest插件和elasticsearch之间的不兼容。 我建议下载ingest插件版本6.4。或者移除它

sudo-bin/elasticsearch插件安装摄取附件

sudo-bin/elasticsearch插件移除摄取附件

可以从下载此插件进行脱机安装

脱机安装： 要从本地文件系统的/path/To/plugin.zip安装插件，您可以运行：

sudo-bin/elasticsearch插件安装file:///path/to/plugin.zip

python manage.py indexdocs

curl -XGET http://localhost:9200
