Kibana interface open problem

Elastic Stack Kibana
1

Hi all,

I installed elasticsearch 5.2.2 and kibana 5.2.2 on one ec2 instance. Both runs without any issue. But I cannot open kibana interface, for example in localhost mode, I can check kibana interface by 127.0.0.1:5601. My ec2 current IP for example is 172.31.12.21, why I cannot open that kibana interface by 172.31.12.21:5601 through the browser. Thanks for your answer.

Here's my kibana.yml:

server.host: "172.31.12.21"
elasticsearch.url: "http://172.31.12.21:9200"

Here's my elasticsearch.yml:

network.host: 172.31.21.47
node.master: true
node.data: true
cluster.name: mastertest
action.auto_create_index: true
bootstrap.system_call_filter: false
path.logs: /mnt/volume/logs
path.data: /datab
discovery.zen.ping.unicast.hosts: ["172.31.21.47:9300"]

Could you confirm that kibana is listening on that IP and port?

lsof -Pan -p <kibana-PID> -i

Also, I noticed in your kibana.yml your elasticsearch url doesn't match your elasticsearch.yml's network.host setting. Is that a mistake?

use command

netstat -tupln

And looking for port 5601. What is ip listening? Your IP or 127.0.0.1.
If u see 127.0.0.1:5601. Open kibana config and change localhost to your IP (172.31.12.21)

/etc/kibana/kibana.yaml

server.host: "localhost" (line 7)

Sorry, I made a mistake. But after I changed, I still cannot see Kibana interface by tying 172.31.12.21:5601. Any ideas? Thanks.

Here's my kibana.yml:

server.host: "172.31.12.21"
elasticsearch.url: "http://172.31.12.21:9200"

Here's my elasticsearch.yml:

network.host: 172.31.12.21
node.master: true
node.data: true
cluster.name: mastertest
action.auto_create_index: true
bootstrap.system_call_filter: false
path.logs: /mnt/volume/logs
path.data: /datab
discovery.zen.ping.unicast.hosts: ["172.31.12.21:9300"]

Check if the firewall is blocking the traffic in the port 9200, 5601
Also in EC2 security group you have to add the above ports.

EC2 security group setting Inbound:

Type Protocol Port Range Source
All traffic All All 0.0.0.0/0

Is that correct if I set as all traffic?

hi,
You can set inbound as above for test proposes for a short time.

What is you outbound setting ? Does it include port 5601?
which linux flavour do you use? Do the firewall rules let port 5601 out. ?

systemctl status firewalld

Are you sure 172.31.21.47 is the public allocated by AWS when the instance started, could you be using the private IP by mistake ?

When you give below command is pot 5601 listed as LISTENING. ?
tcp 0 0 0.0.0.0:5601 0.0.0.0:* LISTEN 123/node

netstat -anp
