Not able to load Kibana on port 5601

Question

I have installed Elasticsearch, Logstash, Kibana and Nginx following this guide,

https://www.digitalocean.com/community/tutorials/how-to-install-elasticsearch-logstash-and-kibana-elk-stack-on-ubuntu-14-04

Elasticsearch is running on 9200

But running

curl http://localhost:5601

returns this:

curl: (7) Failed to connect to localhost port 5601: Connection refused

In kibana.yml file I configured

server.port: 5601

server.host: "127.0.0.1"

Here I also checked with localhost and aws private ip address.

And while checking the port running this:

netstat -anp | grep 5601

I am getting:

(No info could be read for "-p": geteuid()=1000 but you should be root.)

I can start kibana running:

sudo service kibana start

But while checking status using:

sudo service kibana status

I get:

kibana is not running

I haven't setup firewall and running

sudo ufw status

Returns:

Status : Inactive

I am confused, why is the kibana port not listening?

Answer 1

You can check Kibana logs for why it is not starting at all. You may find things like kibana unable to connect elasticsearch at given url.

Answer 2

Its running now. When I checked kibana log (vi /var/log/kibana/kibana.stderr)

Error: EACCES, permission denied '/opt/kibana/optimize/.babelcache.json'

So I changed permission for the file .babelcache.json

sudo chown -R kibana:root /opt/kibana/optimize/.babelcache.json

Then restarted kibana , and this solved the issue.
