弹性搜索HTTPConnectionPool（host='127.0.0.1'，端口= 9200）：超出最大重试

Question

我有一个弹性的搜索服务器，我正在从直播网站和Django Management命令查询。管理命令在凌晨3点格林威治标准时间使用Celery Beat运行，以同步来自外部服务的数据。有时（但不是每次）此命令运行弹性搜索似乎崩溃，我在错误日志中获得以下错误。

.

我正在使用pyelasticsearch在我的settings.py文件中使用以下代码连接到弹性搜索：

try:
    ES_CON
except NameError:
    ES_CON = None

if not ES_CON:
    ES_CON = ElasticSearch(ELASTICSEARCH_URI)

.

任何帮助将非常感激。

我会建议使用官方elasticsearch python客户端：弹星术 - 具有可靠连接处理的PY 是线程安全等。它也更快（根据作者，谁是Elasticsearch团队的一部分）。

然后，您可以在es = Elasticsearch()的顶部或在例如，在例如，您可以使用您的tasks.py。来自那里的core.helpers和导入生成的世代odicetagcode。
