我有一个弹性搜索服务器，我从实时网站和 Django 管理命令查询。管理命令在格林威治标准时间凌晨 3 点使用 celery beat 运行，以同步来自外部服务的数据。有时（但不是每次）运行此命令时，弹性搜索似乎会崩溃，并且我在错误日志中收到以下错误。

我正在使用 pyelasticsearch 通过我的 settings.py 文件中的以下代码连接到 Elastic Search：

try:
    ES_CON
except NameError:
    ES_CON = None

if not ES_CON:
    ES_CON = ElasticSearch(ELASTICSEARCH_URI)

任何帮助将不胜感激。

我建议使用官方的 Elasticsearch python 客户端：elasticsearch-py，它具有可靠的连接处理、线程安全等。它也更快（据作者说，他是 Elasticsearch 团队的一员）。

然后，您可以将您的es = Elasticsearch()或者放在您的顶部tasks.py，或者在例如并从那里core.helpers导入。es
