Kibana server is not ready yet

[subhas (Subhas Takhellambam)]

Kibana url is not working. Whether kibana service is started or stopped, it is giving the same error when i go to http://localhost:9243 - "Kibana server is not ready yet". I am using centos 7. But the elasticsearch and kibana are on 6.5
Thank you in advance.

Hi

More info would be helpful, logs, screenshots console errors.

Can you please check the kibana server configuration in kibana.yml file? Have you defined the elasticserach node IP in elasticserach.uri under kibana.yml file?

Thanks
Rashmi

Thank you Rashmi. Here is my kibana.xml
server.port: 9243
server.host: "0.0.0.0"
elasticsearch.url: "http://localhost:9200"

I get the below log whenever I restart kibana.

{"type":"log","@timestamp":"2018-11-19T09:12:11Z","tags":["info","migrations"],"pid":12004,"message":"Creating index .kibana_2."}
{"type":"log","@timestamp":"2018-11-19T09:12:11Z","tags":["warning","migrations"],"pid":12004,"message":"Another Kibana instance appears to be migrating the index. Waiting for that migration to complete. If no other Kibana instance is attempting migrations, you can get past this message by deleting index .kibana_2 and restarting Kibana."}

Are the ES logs available during this time? Ho w many nodes do you have ? Also try removing read-only from all indices:

curl -X PUT http://localhost:9200/_all/_settings -H 'Content-Type: application/json' -d'{ "index.blocks.read_only_allow_delete" : false } }'
and check to see if Kibana finishes migrations.

There is a also a breaking change after an upgrade to 6.5, have you checked the release notes? (https://www.elastic.co/guide/en/kibana/current/release-notes-6.5.0.html#known-issues-6.5.0 ).

Thanks
