Question

我正在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）时都会遇到此问题：

elasticsearch.exceptions.ConnectionError: ConnectionError(<urllib3.connection.HTTPConnection object at 0x7f4e2ab26438>: Failed to establish a new connection: [Errno 111] Connection refused) caused by: NewConnectionError(<urllib3.connection.HTTPConnection object at 0x7f4e2ab26438>: Failed to establish a new connection: [Errno 111] Connection refused)

例如对于Django，我执行以下命令：

sudo service elasticsearch start

然后

python manage.py indexdocs

我收到如下问题。我试图做：

curl -XGET http://localhost:9200

我得到了：curl: (7) Failed to connect to localhost port 9200: Connexion refusée

您对此有任何想法吗？我必须在某个地方授权一些东西吗？

谢谢

在/var/log/elasticsearch/elasticsearch.log中，我遇到了循环问题：

问题在于摄取插件和elasticsearch之间的不兼容。我建议下载摄取插件版本6.4。或将其删除。

sudo bin / elasticsearch-plugin安装接收附件

sudo bin / elasticsearch-plugin删除摄取附件

可以从https://artifacts.elastic.co/downloads/elasticsearch-plugins/ingest-attachment/ingest-attachment-6.4.0.zip下载此插件以进行脱机安装。

离线安装：要从本地文件系统/path/to/plugin.zip安装插件，可以运行：

sudo bin / elasticsearch-plugin安装文件：///path/to/plugin.zip

Elasticsearch问题：ConnectionError
