elasticsearch异常ConnectionError

标签： python django elasticsearch django-haystack

我正在制作一个Django应用。它使用带有弹性搜索的Haystack作为后端。

当我跑步时

./manage.py rebuild_index

我收到此错误：

  

已中止。＆＃39;，错误（61，＆＃39;连接被拒绝＆＃39;）））   引起的：ProtocolError（（＆＃39;连接中止。＆＃39;，错误（61，＆＃39;连接被拒绝＆＃39;））

导致这种情况的原因是什么？

运行bin / elasticsearch给出了这个：

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

我做错了什么？

答案 0 :(得分：8)

拒绝连接意味着拒绝与Elasticsearch HTTP服务的TCP连接。原因可能是许多事情，例如您使用错误的主机或端口作为HTTP端点，或者弹性搜索节点由于某种原因未运行。

在尝试使用Haystack之前，通过发出类似以下内容的直接HTTP请求来测试elasticsearch的工作原理：

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

其中192.168.77.88是elasticsearch节点的IP地址，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',
    },
}

答案 1 :(得分：1)

我遇到了同样的问题。通过在端口9200上实际运行Elasticsearch来解决问题。如果您在Windows上，请转到Elasticsearch安装的bin目录并运行您正在使用的任何Elasticsearch版本的批处理文件。
