我在做一个Django应用。它使用Haystack和elasticsearch作为后端。
当我跑的时候

./manage.py rebuild_index

我得到这个错误：
aborted.'，error（61，'Connection refused '））），原因是：ProtocolError（（'Connection aborted.'，error（61，'Connection refused'）））
是什么造成的？
日志：

./manage.py rebuild_index
No handlers could be found for logger "django_facebook.models"

运行bin/elasticsearch得到：

但是在运行ps时-一个elasticsearch不会显示为一个正在运行的进程。
我做错了什么？

Connection refused仅仅意味着到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，或者由于某种原因elasticsearch节点没有运行。
在尝试使用Haystack之前，通过发出直接的HTTP请求来测试elasticsearch的工作情况，如下所示：

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。成功后，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',
    },
}

我也有同样的问题。刚刚通过在端口9200上运行Elasticsearch解决了这个问题。如果你是在windows上，后藤Elasticsearch安装的bin目录，然后运行你正在使用的任何Elasticsearch版本的批处理文件。

anton评论救了我！
我来到这里是因为我试图运行elasticsearch-curator，我得到了以下错误（即使没有防火墙或其他连接拦截器）：

user@host:/opt/elasticsearch-curator$ curator_cli show-indices | more
2021-11-20 16:33:11,396 INFO      Instantiating client object
2021-11-20 16:33:11,397 INFO      Testing client connectivity
2021-11-20 16:33:11,403 ERROR     HTTP N/A error: HTTPConnectionPool(host='127.0.0.1', port=9200): Max retries exceeded with url: / (Cause
d by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f5ca8ba7d60>: Failed to establish a new connection: [Errno 111] C
onnection refused'))
2021-11-20 16:33:11,403 CRITICAL  Curator cannot proceed. Exiting.

由于我实验室中的许多其他特殊性，我在我的/etc/elasticsearch/elasticsearch.yml中有一行network.hosts: 10.0.0.134，这意味着该VM的私有IP在配置中是固定的，因此我的elasticsearch没有绑定到所有地址，因为在大多数情况下它应该绑定到所有地址。解决方案是在文件/etc/elasticsearch/elasticsearch. yml中添加一行network.bind_host: 0.0.0.0。这样，我的/etc/elasticsearch/elasticsearch.yml的网络会话如下：

# ---------------------------------- Network -----------------------------------
#
# By default Elasticsearch is only accessible on localhost. Set a different
# address here to expose this node on the network:
#
network.host: 10.0.0.134
#
# By default Elasticsearch listens for HTTP traffic on the first free port it
# finds starting at 9200. Set a specific HTTP port here:
#
http.port: 9200
#
network.bind_host: 0.0.0.0
#
# For more information, consult the network module documentation.
#

现在我的elasticsearch-curator工作得很好：

我希望它能帮助那些面临同样问题的人。

I make it  sudo nano /etc/elasticsearch/elasticsearch.yml
network.host: 45.#.#.#
transport.host: localhost

对我很有效
