我试图建立一个简单的django弹片搜索，可以搜索汽车。但是当我试图反驳索引时，它给了我上面的错误。我正在关注此文档->quickstart elasticsearch…下面给出了完整的回溯->

elasticsearch.exceptions.ConnectionError: ConnectionError(<urllib3.connection.HTTPConnection object at 0x7f09b9f0a7c0>: Failed to establish a new connection: [Errno 111] Connection refused) caused by: NewConnectionError(<urllib3.connection.HTTPConnection object at 0x7f09b9f0a7c0>: Failed to establish a new connection: [Errno 111] Connection refused)

my models.py是一个简单的汽车模型，有名称、颜色、描述、类型字段，我在文档中添加了这些字段

class Car(models.Model):
    name = models.CharField(max_length=50)
    color = models.CharField(max_length=50)
    description = models.TextField()
    type = models.IntegerField(choices=[
        (1, "Sedan"),
        (2, "Truck"),
        (4, "SUV"),
    ])

my documents.py文件->

from django_elasticsearch_dsl import Document
from django_elasticsearch_dsl.registries import registry
from .models import Car

@registry.register_document
class CarDocument(Document):
    class Index:
        name = 'cars'
        settings = {'number_of_shards': 1,
                    'number_of_replicas': 0}

    class Django:
        model = Car

        fields = [
            'name',
            'color',
            'description',
            'type',
        ]

但是，当我试图反驳索引时，它给出了新的连接错误。下面给出了我用来重建索引的命令->

python manage.py search_index --rebuild

elasticsearch python django django-rest-framework Document

首先，确保您已正确安装和配置elasticsearch服务（您可以使用此文档）。此错误表示您的代码无法连接到 ElasticSearch 使用当前配置提供服务。检查弹性服务是否启动并运行。在基于linux的操作系统中，您可以通过 $ sudo systemctl status elasticsearch.service 在结果页面你应该看到 Active: active (running) . 完成此步骤后，请检查url http://localhost:9200/ （如果您没有更改默认设置）并且如果一切正常，您将看到以下结果：

{
  "name" : "some_name-System-Product-Name",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "erP_jdhLRvuwqLkx1_tehw",
  "version" : {
    "number" : "7.9.0",
    "build_flavor" : "default",
    "build_type" : "deb",
    "build_hash" : "a479a2a7fce0389512d6a9361301708b92dff667",
    "build_date" : "2020-08-11T21:36:48.204330Z",
    "build_snapshot" : false,
    "lucene_version" : "8.6.0",
    "minimum_wire_compatibility_version" : "6.8.0",
    "minimum_index_compatibility_version" : "6.0.0-beta1"
  },
  "tagline" : "You Know, for Search"
}

您也可以使用启动此服务 $ sudo systemctl start elasticsearch.service . 另一种可能性是，可能您以错误的方式配置了弹性变量。例如，使用错误的端口而不是默认端口（即9200）也会引发相同的错误。在下面的示例中，您可以看到一个弹性配置的示例，它将放在项目的 settings.py :


# ElasticSearch configs

ELK_BASE_URL = 'elasticsearch://{username}:{password}@{host_ip}:{host_port}'
ELASTIC_SEARCH_URL = ELK_BASE_URL.format(
    username='ELASTICSEARCH_USER',
    password='ELASTICSEARCH_PASS',
    host_ip='ELASTICSEARCH_HOST',
    host_port='ELASTICSEARCH_PORT'
)
ELASTICSEARCH_DSL = {
    'default': {
        'hosts': [ELASTIC_SEARCH_URL]
    },
}
