Kibana - elasticsearch connexion

Elastic Stack Kibana
1

Hello everyone,

I just installed Kibana and Elasticsearch on my server. I downloaded versions 8.2.0 in tar.gz on Linux.

To set up these two software, I modified two documents:

  • elasticsearch.yml
  • kibana.yml

Here is the content of these two files:

For elasticsearch.yml:

cluster.name: my-elasticsearch
node.name: node1
path.data: /db/myappli/data/elasticsearch
path.logs: /db/myappli/logs/elasticsearch
network.host: myservername
http.port: 9206
discovery.seed_hosts: ["myservername"]
cluster.initial_master_nodes: ["myservername"]
xpack.security.enabled: false

For kibana.yml:

server.port: 5606
server.host: "myservername"
server.name: "myservername"
elasticsearch.hosts: ["http://myservername:9206"]

It's not working, my Elasticsearch can be launched and starts, but my Kibana doesn't. The logs of Kibana say:

 FATAL  TimeoutError: Request timed out

By removing the connection to the Elasticsearch database in kibana.yml, Kibana launches and is OK. Like this :

kibana.yml :

server.port: 5606
server.host: "myservername"
server.name: "myservername"

On the Elasticsearch side, when I go to this URL: http://myservername:9206

I get this:

{
  "name" : "myservername",
  "cluster_name" : "mes-elasticsearch-prod",
  "cluster_uuid" : "_na_",
  "version" : {
    "number" : "8.2.0",
    "build_flavor" : "default",
    "build_type" : "tar",
    "build_hash" : "b174af62e6dd9f4ac4d25875e9781ffe2b9482c5",
    "build_date" : "2022-04-20T10:35:10.180408517Z",
    "build_snapshot" : false,
    "lucene_version" : "9.1.0",
    "minimum_wire_compatibility_version" : "7.17.0",
    "minimum_index_compatibility_version" : "7.0.0"
  },
  "tagline" : "You Know, for Search"
}

Yes, it seems that your Elasticsearch is working properly and your Kibana is not able to connect to it.

Do you have any ideas for making it work?
Please help me ! :worried:

  1. If you have Kibana and Elasticsearch installed on the same host, you should use the loopback address
  2. If Kibana is on a separate host, try connecting to Elasticsearch on that host using a network utility such as curl
  3. If there is a proxy in between Kibana and Elasticsearch, check the proxy logs for errors

By removing the connection to the Elasticsearch database in kibana.yml, Kibana launches and is OK.

Does "OK" mean there is a different symptom?
