I have a question reagrdless testing a server and playing around with it. I have set up a local elasticsearch databse and kibana. Now I want to connect to the server from antoher PC on the same network.
My questions are, is that server already up and able for access or do I need apache/wamp or smth third to get the local elastic online for other useres? How to connect to the server when it's up? All the usefull info would be appreciated!
By default Elasticsearch listen on loopback interface (localhost / 127.0.0.1).
You must change configuration. Edit the file elasticsearch.yml like this :
network.host: 0.0.0.0
For listening on all IP addresses of your computer.

Every guide or post about this topic says to just set network.host: 0 in the elasticsearch.yml file. However I tried that, along with applying other troubleshooting methods, and nothing seems to work. I'm starting to think maybe the configuration is right, but I am not connecting to it the right way?
This is what my yml file looks like,
discovery.seed_hosts: []
network.publish_host: xx.xxx.xxx.51
network.host: 0.0.0.0
The elastic search server is hosted on an Azure virtual machine. Then when I try to connect to it via curl on my local machine I get a Failed to Connect, Timeout Error.
curl http://xx.xxx.xxx.51:9200
The issue was with the network settings which was blocking all the incoming traffic and once incoming traffic on port 9200, default port of Elasticsearch allowed, the issue got resolved.
Just for the reference, you just need to have network.host: 0.0.0.0 config to make sure Elasticsearch isn't using the loopback address and this by default kicks in the production checks which can be avoided in case you are just running a single node discovery.type:single-node, this helps to troubleshoot such issues.
I am using elastic search in my ubuntu16.04 server. When i am trying to access elasticsearch from browser by using url ip:port/_cat/indices?v. I am getting site can't be reached. After that i am change the network.host value to network.host: 0.0.0.0. After change the network.host ip the search engine not started. How can i access the elasticsearch in my browser.I changed the port also.
Thank you..
There can be many reasons for ES not being reachable. I would start with the obvious and make sure that:
ES is listening on the port: on the ES instance when you run 'curl
ip:port' you should get an answer. if not the service didn't start
well.
make sure there are no firewall rules/security groups that prevent
access from remote network.
make sure network.publish_host is configure correctly:

I'm using grafana cloud for creating visualization but when i'm trying to load the data source with elasticsearch i'm getting 502 error.
502 usually means bad gateway (there is no connection) and that IP address looks like an internal IP address. GrafanaCloud is a cloud service so it does not have access to internal IP addresses.
Your options are:
Install Grafana locally if you do not want to open up anything over the internet.
Use direct mode instead of proxy mode. This means that requests will go directly from your browser to the elasticsearch server and not go through the Grafana backend server. However, GrafanaCloud is on https so you will get a mixed content warning and you would need to solve that by having a proxy in front of your elasticsearch server (or by setting up https for your server).
Make your server accessible over the internet. Setup a static IP address for your elasticsearch server, setup firewall rules etc. so that GrafanaCloud can query your server.
Add the following configurations in config/elasticsearch.yml:
transport.host: localhost
transport.tcp.port: 9300
http.port: 9200
network.host: 0.0.0.0
I want to connect my elasticsearch cluster from another machine i went through some documentation where they had mentioned that i had change the network.bind_host : 0 .But i didn't find the network.bind_host in my elasticsearch.yml . I got only network.host in my elasticsearch.yml file.Even i tried it by giving as
network.host :0 but i cant able to connect from another machine. And i also tried removing ## before network.host :0 which throws an error when starting elasticsearch cluster.
When i am connecting from another machine i have to give http://clustermachingip:9200 right?
Can anyone please help on this problem?
Thanks..
When you want to connect to an elasticsearch instance of an another machine, yes the address is http://clustermachingip:9200. Can you try setting network.bind_host: clustermachingip
If this doesn't work then you might want to check the connectivity to the machine you are trying to connect to using something like a ping command.
ping clustermachingip
EDIT:
You can just start elasticsearch in one machine and try one of the following curl commands from the other machine.
curl 'clustermachingip:9200/_cat/nodes?v'
curl 'clustermachingip:9200/_cat/health?v'
EDIT2: Clearing out confusion between network.host, network.bind_host
https://www.elastic.co/guide/en/elasticsearch/reference/2.4/modules-network.html#advanced-network-settings
The network.host setting explained in Commonly used network settings
is a shortcut which sets the bind host and the publish host at the
same time. In advanced used cases, such as when running behind a proxy
server, you may need to set these settings to different values:
network.bind_host
This specifies which network interface(s) a node should bind to in order to listen for incoming requests. A node can bind to multiple
interfaces, e.g. two network cards, or a site-local address and a
local address. Defaults to network.host. network.publish_host
The publish host is the single interface that the node advertises to other nodes in the cluster, so that those nodes can connect to it.
Currently an elasticsearch node may be bound to multiple addresses,
but only publishes one. If not specified, this defaults to the “best”
address from network.host, sorted by IPv4/IPv6 stack preference, then
by reachability.
Set your network.host in elasticsearch.yml to 0.0.0.0 i.e. it will listen on all available bound addresses.
network.host: 0.0.0.0
Check your connectivity to the host machine on the port (in case you haven't changed the port it will be 9200).
In case you are not able to connect to the host machine still, I will suggest checking your iptables and allow connections to port 9200.
Despite ElasticSearch and Kibana both running on my production server, I'm unable to visit the GUI over the public IP: http://52.4.153.19:5601/
Localhost curls return 200 but console errors on the browser report timeouts after a few images are retrieved.
I've successfully installed, run, and accessed Kibana on my local (Windows 10) and on my staging AWS EC2 Ubuntu 14.04 environment. I'm able to access both over port 5601 on localhost and the staging environment is accessible over the public IP address and all domains addressed accordingly. The reverse proxy also works and all status indicators are green on the dashboard.
I'm running Kibana 4.5, ElasticSearch 2.3.1, Apache 2.4.12
I've used the same exact volume from the working environment to attach to the production instance, so everything is identical on the two volumes, except that the staging environment's apache vhost uses a subdomain while the production environment's servername is the base domain. Both are configured for SSL wildcards. Both are in separate availability zones at Amazon. I've tried altering the server block to use a subdomain on the production server, just to see if the domain was impactful but the error remains.
I also tried running one instance individually, in case EC2 had some kind of networking error with 0.0.0.0 but I'm unable to come to a resolution. All logs and configurations are identical between the two servers for ElasticSearch and Kibana.
I've tried deleting and re-creating the kibana index, tried alternate settings inclusive of the host, elasticsearch url, extending the max ping and timeout, max retries, extended the apache limits, http.cors to allow different origins. I've tried other ports but both servers are indicating that 5601 is listening in the same way.
I also had the same problem on a completely different volume that was previously attached to this instance.
The only difference I can see is that the working version pings fine while the non-working version has a 100% packet loss when pinging the IP, although I can't imagine why that would be, as I'm able to reach the website on 80, just fine. I can also access various other tools running on other ports. I assume there might be some kind of networking conflict. Any ideas?
May be port 5601 is blocked by firewall
Allow incoming connections to port 5601 by:
sudo iptables -I INPUT -p tcp --dport 5601 -j ACCESS
For security:
Modify above mentioned command and accept connection only from specific address. (See man iptables)
or use Shield plugin for elasticseach
Sorry, forgot to update this question. The answer turned out being that I simply needed to deploy a new instance. Simply by creating a clone of the instance, I was able to resolve the issue. I've had networking problems at AWS, before, with their internal dns/ip conflicts, so I've had to do so, in the past and this turned out to be the quickest and cleanest solution, albeit not providing any definitive insight into the cause.
