Эластичное поисковое завихрение-X ДОБИРАЕТСЯ “localhost:9200 /” Соединение, которому Отказывают

Я следовал инструкциям в https://www.elastic.co/guide/en/elasticsearch/reference/current/deb.html для установки elasticsearch на чистой установке Сервера Ubuntu 16.04.

Я выполнил следующие команды через терминал для установки.

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.3.0.deb

sudo dpkg -i elasticsearch-6.3.0.deb

sudo /bin/systemctl daemon-reload

sudo /bin/systemctl enable elasticsearch.service

sudo systemctl start elasticsearch.service

Однако, когда я работаю curl -X GET "localhost:9200/" Я получаю следующую ошибку

curl: (7) Failed to connect to localhost port 9200: Connection refused

Это - содержание /etc/elasticsearch/elasticsearch.yml

# ======================== Elasticsearch Configuration =========================
#
# NOTE: Elasticsearch comes with reasonable defaults for most settings.
#       Before you set out to tweak and tune the configuration, make sure you
#       understand what are you trying to accomplish and the consequences.
#
# The primary way of configuring a node is via this file. This template lists
# the most important settings you may want to configure for a production cluster.
#
# Please consult the documentation for further information on configuration options:
# https://www.elastic.co/guide/en/elasticsearch/reference/index.html
#
# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#
#cluster.name: my-application
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
#node.name: node-1
#
# Add custom attributes to the node:
#
#node.attr.rack: r1
#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
path.data: /var/lib/elasticsearch
#
# Path to log files:
#
path.logs: /var/log/elasticsearch
#
# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
#
#bootstrap.memory_lock: true
#
# Make sure that the heap size is set to about half the memory available
# on the system and that the owner of the process is allowed to use this
# limit.
#
# Elasticsearch performs poorly when the system is swapping the memory.
#
# ---------------------------------- Network -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
network.host: localhost
#
# Set a custom port for HTTP:
#
http.port: 9200
#
# For more information, consult the network module documentation.
#
# --------------------------------- Discovery ----------------------------------
#
# Pass an initial list of hosts to perform discovery when new node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
#
#discovery.zen.ping.unicast.hosts: ["host1", "host2"]
#
# Prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1):
#
#discovery.zen.minimum_master_nodes:
#

Любые предложения или совет ценились бы, чтобы помочь мне разбудить elasticsearch и выполнение.
