Hi guys,

I had install elasticsearch and kibana on ec2 instance.

If I run locally both elasticsearch and kibana working

[ec2-user@ip-10-0-1-168 ~]$ curl http://localhost:9200
{
  "name" : "_MF1kzR",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "Gm_7rlYySiCFPBUWi1QmDw",
  "version" : {
    "number" : "6.4.0",
    "build_flavor" : "default",
    "build_type" : "rpm",
    "build_hash" : "595516e",
    "build_date" : "2018-08-17T23:18:47.308994Z",
    "build_snapshot" : false,
    "lucene_version" : "7.4.0",
    "minimum_wire_compatibility_version" : "5.6.0",
    "minimum_index_compatibility_version" : "5.0.0"
  },
  "tagline" : "You Know, for Search"
}

Kibana

[ec2-user@ip-10-0-1-168 ~]$ curl http://localhost:5601
&lt;script&gt;var hashRoute = '/app/kibana';
var defaultRoute = '/app/kibana';
var hash = window.location.hash;
if (hash.length) {
window.location = hashRoute + hash;
} else {
window.location = defaultRoute;
}&lt;/script&gt;
[ec2-user@ip-10-0-1-168 ~]$

I think that it's running loaclly but, When i access in browser its not working

[ec2-user@ip-10-0-1-168 ~]$ sudo service kibana status

kibana is not running

[ec2-user@ip-10-0-1-168 ~]$ sudo service kibana restart 

kibana started

[ec2-user@ip-10-0-1-168 ~]$ sudo service kibana status

kibana is not running

I accessed by other machine through curl, getting the output:

curl: (7) Failed to connect to 1.x.x.x port 5601: Connection refused`

Please help me to solve this

This is likely the problem. A process listening on localhost will only be accessible from that PC. If you change this line to:

server.host: 10.0.1.168

This will listen on the externally facing interface and you should be able to access. You can verify this by running lsof -Pi :5601. A process listening only on localhost:

COMMAND  PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
nc      4731 root    3u  IPv4  30860      0t0  TCP localhost:5601 (LISTEN)

Versus a process listening on both localhost externally (note the 10.0.1.168 instead of localhost):

COMMAND  PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
nc      4787 root    4u  IPv4  31641      0t0  TCP 10.0.1.168:5601 (LISTEN)

and

[ec2-user@ip-10-0-1-168 ~]$ sudo lsof -Pi :5601
COMMAND  PID   USER   FD   TYPE DEVICE SIZE/OFF NODE NAME

This is the same problem now, but the other way round. You have elastic listening on the external interface but you're trying to connect using localhost. Just remember:

If the process is listening on localhost, you need to connect to localhost
If the process is listening on 10.x.x.x, you need to connect to 10.x.x.x
