Failed to establish a new connection: [Errno 111] Connection rejected (elasticsearch)

Question

I installed elasticsearch using the following command: pip install elasticsearch After installation, I ran the following commands:

>>> from datetime import datetime
>>> from elasticsearch import Elasticsearch
# by default we connect to localhost:9200
>>> es = Elasticsearch()
# create an index in elasticsearch, ignore status code 400 (index already     exists) #but when I run this instruction:
>>> es.indices.create(index='my-index', ignore=400) // HERE IS THE PROBLEM

I get this error:

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "elasticsearch/client/utils.py", line 69, in _wrapped
return func(*args, params=params, **kwargs)

What you installed is a Python client that is used to communicate between your Python script and an existing Elasticsearch cluster.

As already mentioned in your comment, at the top of the page that you started reading, it says:

Elasticsearch. - , Elasticsearch, Python; - .
