Elasticsearch won't bind to localhost

[sudoroot]

I am trying to set up Elasticsearch on a VM running CentOS 7. I've followed the configuration guide, but ES will not bind to 127.0.0.1:9200. The configuration is as follows:

 # 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: logging-prod
 
 #
 
 # ------------------------------------ Node ------------------------------------
 
 #
 
 # Use a descriptive name for the node:
 
 #
 
 node.name: "prod-data-1"
 
 #
 
 # Add custom attributes to the node:
 
 #
 
 #node.attr.rack: r1
 
 #
 
 #node.data:false
 
 #
 
 index.number_of_shards:1
 
 #
 
 index.number_of_replicas:0

 #
 
 # ----------------------------------- 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: 127.0.0.1
 
 #
 
 # 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 this node is started:
 
 # The default list of hosts is ["127.0.0.1", "[::1]"]
 
 #

 #discovery.seed_hosts: ["host1", "host2"]
 
 #
 
 # Bootstrap the cluster using an initial set of master-eligible nodes:
 
 #
 
 cluster.initial_master_nodes: ["prod-data-1"]
 
 #
 
 # For more information, consult the discovery and cluster formation module documentation.
 
 #
 
 # ---------------------------------- Gateway -----------------------------------
 
 #
 
 # Block initial recovery after a full cluster restart until N nodes are started:
 
 #
 
 #gateway.recover_after_nodes: 3
 
 #
 
 # For more information, consult the gateway module documentation.
 
 #
 
 # ---------------------------------- Various -----------------------------------
 
 #
 
 # Require explicit names when deleting indices:
 
 #
 
 #action.destructive_requires_name: true
