Python 弹性搜索异常连接错误

elasticsearch exceptions ConnectionError

提问by Deepti

I am making a Django app. It uses Haystack with elasticsearch as backend.

我正在制作一个 Django 应用程序。它使用 Haystack 和 elasticsearch 作为后端。

When I run

当我跑

./manage.py rebuild_index

I get this error:

我收到此错误：

aborted.', error(61, 'Connection refused'))) caused by: ProtocolError(('Connection aborted.', error(61, 'Connection refused')))

aborted.', error(61, 'Connection denied'))) 引起： ProtocolError(('Connection aborted.', error(61, 'Connection denied')))

What could have caused this?

这可能是什么原因造成的？

The log:

Running bin/elasticsearch gives this:

运行 bin/elasticsearch 给出了这个：

But on running ps -A elasticsearch does not show up as a running process.

但是在运行 ps -A elasticsearch 时不会显示为正在运行的进程。

What am I doing wrong?

我究竟做错了什么？

Connection refused means just that, that the TCP connection to the Elasticsearch HTTP service was refused. The reason can be a number of things, for instance that you are using the wrong host or port for the HTTP endpoint, or that the elasticsearch node is not running for some reason.

连接被拒绝只是意味着，到 Elasticsearch HTTP 服务的 TCP 连接被拒绝。原因可能有很多，例如您为 HTTP 端点使用了错误的主机或端口，或者 elasticsearch 节点由于某种原因没有运行。

Before you try to use Haystack, test that elasticsearch works by issuing a direct HTTP request with something like:

在您尝试使用 Haystack 之前，请通过发出类似以下内容的直接 HTTP 请求来测试 elasticsearch 是否工作：

curl -X GET http://192.168.77.88:9200/_cat/indices

Where 192.168.77.88is the IP address of your elasticsearch node, and 9200is the TCP port. When that succeeds, check and double check that you have the same URL configuration in you Haystack config.

192.168.77.88你的elasticsearch节点的IP地址在哪里，9200是TCP端口。如果成功，请检查并仔细检查您在 Haystack 配置中是否具有相同的 URL 配置。

HAYSTACK_CONNECTIONS = {
    'default': {
        'ENGINE': 'haystack.backends.elasticsearch_backend.ElasticsearchSearchEngine',
        'URL': 'http://192.168.77.88:9200/',
        'INDEX_NAME': 'haystack',
    },
}

I had the same problem. Just got it resolved by actually running the Elasticsearch on port 9200. If you are on windows, goto the bin directory of Elasticsearch installation and run the batch file of whichever Elasticsearch version you are using.

我有同样的问题。刚刚通过在端口 9200 上实际运行 Elasticsearch 解决了它。如果您在 Windows 上，请转到 Elasticsearch 安装的 bin 目录并运行您使用的任何 Elasticsearch 版本的批处理文件。
