Question

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来同步来自外部服务的数据。有时（但不是每次）运行此命令弹性搜索似乎崩溃，我在错误日志中收到以下错误。

我正在使用pyelasticsearch在我的settings.py文件中使用以下代码连接到Elastic Search：

try:
    ES_CON
except NameError:
    ES_CON = None

if not ES_CON:
    ES_CON = ElasticSearch(ELASTICSEARCH_URI)

非常感谢任何帮助。

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

然后，您可以将es = Elasticsearch()放在tasks.py的顶部，或者例如core.helpers。 es并从那里导入{{1}}。

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