I've install ES on my VM which it has an OS of centos 7. It network.host: bind to the localhost. I can browse via port 9200.
My problem is that I've changed the network host to:0.0.0.0 (So I can get public access from my host PC).
the service started but the port is not listening.
I want to access ES from my host PC.
How can i change the network.host ?
I faced same issue in elasticsearch 7.3.0 version. I resolved by putting following
values in /etc/elasticsearch/elasticsearch.yaml as shown below
network.host: 127.0.0.1
http.host: 0.0.0.0
If you are planning to set network.host other than default(127.0.0.1) then change following details in /etc/elasticsearch/elasticsearch.yml
network.host: 0.0.0.0
discovery.seed_hosts: []
Looking at the Elasticsearch Network Settings documentation, it doesn't appear that 0.0.0.0 is a valid setting for network.host.
Try instead the special value _global_. So the section of your elasticsearch.yaml might look like this:
network:
host: _global_
This should tell Elasticsearch to listen on all network interfaces.
Since the version 7.3 of Elastic Search, it's necessary to put the following line
cluster.initial_master_nodes: node-1
network.host: 0.0.0.0
If your application is running on AWS and Elastic search is running on different host
network.host: YOUR_AWS_PRIVATE_IP
This works for me.

I wish to run my elasticsearch remotely on gcloud VM, this is configured to run at 127.0.0.1 at a specific port 9200. How to access this from a website outside this vm? If I change the network host to 0.0.0.0 on the yml file, even 9200 port becomes inaccessible. How do I overcome this problem?
Changed network.host: [_site_ , _local_ , _global_ ]
_site_ = internal ip given by google cloud vm,
_local_ = 127.0.0.1,
_global_ = found using curl ifconfig.me,
Opened a specific port (9200) and tried to connect with global IP address.
curl to the global ip gives
>Output: Failed to connect to (_global_ ip) port 9200: connection refused.
So put network.host:0.0.0.0 and then try to allow 9200 and 9201 port and restart the elasticsearch service.If you are using ubuntu then sudo service elasticsearch restart then check by doing curl -XGET 'http://localhost:9200?pretty'.Let me know if you are still facing any issues.
Use following configurations for elasticsearch.yml
network.host: 0.0.0.0
action.auto_create_index: false
index.mapper.dynamic: false
Solved this problem by going through the logs and found out that the public ip address is re-mapped to the internal ip address, hence network.host can't be set to external ip directly. Elasticsearch yml config is as follows:
'network.host: xx.xx.xxx.xx' is set to the internal ip (given by google),
'http.cors.enabled: true',
'http.cors.allow-origin:"*", (Do not use * in production, its a security issue)
'discovery.type: single-node' in my case to make it work independently and not in a cluster
Now this sandboxed version can be accessed from outside the VM using the external IP address given by Google.
ifconfig shows
inet 192.168.10.1
I can access
http://localhost/
http://127.0.0.1/
http://192.168.10.1
They are all the same.
I also can access neo4j and elasticsearch ports on the following urls
Elasticsearch
http://127.0.0.1:9200/
http://localhost:9200/
Neo4j
http://127.0.0.1:7474/browser/
http://localhost:7474/browser/
But port 9200 and 7474 are not working for 192.168.10.1
http://192.168.10.1:9200
http://192.168.10.1:7474
Something I need to do make the port 7474 (neo4j) and 9200 (elasticsearch) working for 192.168.10.1, but I don't know how.
Please advise, thanks!
I figured it out.
Neo4j
Set up neo4j on the ip (except localhost), in my case
http://192.168.10.1:7474
In the neo4j.conf file
uncomment the following line.
# With default configuration Neo4j only accepts local connections.
# To accept non-local connections, uncomment this line:
dbms.connectors.default_listen_address=0.0.0.0
Elasticsearch
Modify elasticsearch.yml
add the following line
network.host: 0.0.0.0
Then start elasticsearch.
I have just installed ElasticSearch 5.0.0. When I run localhost:9200/_cat/nodes?v it gives me ip as 10.57.203.16. But I want localhost as a server. Where should I configure it ?
What if you add the below line to your elasticsearch.yml ,restart the ES and then try querying for the available nodes:
network.host: 127.0.0.1
EDIT:
Try adding a node name in your elasticsearch.yml :
node.name: elastic_test1
I am attempting to set up an elasticsearch cluster. The VMs are RedHat 7 and administered by Puppet. Elasticsearch (2.2) is installed via RPMs managed by Puppet. I would like to have a single elasticesearch.yml file that can be used on all nodes. I can not figure out how to set network.host to the VM's IP address without hardcoding the IP address.
I would like to do something similar to node.name: ${hostname} but for network.host. For example I would like to set network.host to network.host: ${hostname -i} but elasticsearch does not start with this configuration.
How can I set network.host to the IP of the VM without hardcoding the actual IP address?
Within Elastic Configuration:
Setting network.host to ${HOSTNAME} will insert the domain name into your yml variable.
network.host = ${HOSTNAME}
I am trying to access Elastic Search remotely, but getting connection error.
When I curl localhost:9200 in the remote server, I get the desired output. But remotely server_address:9200 is not accessible.
Any suggestions?
In elasticsearch.yml file modify/add network.host setting as below.
network.host: 0.0.0.0
and then restart your elasticsearch server.
Change (/etc/elasticsearch/elasticsearch.yml)network_host IP to your server private IP address.Then the ES can be access with same network range.
network.host: "192.168.xx.xx"
http.port: 9200
Edit your elasticsearch.yml file.
network.host: server_ip
http.port: 9200
transport.tcp.port: 9300
