Kibana server not ready yet

Dear everyone,
Could you please help me solve a problem "kibana server not ready yet" although Elasticsearch and kibana service is running. Attached is the kibana log file.
Thank you so much for your help

Hi @dat_nguyen

Welcome to the community !

Is this a fresh installation? What version and have you checked Elasticsearch is up and running correctly ?

curl -X GET ":9200/_cat/health?v=true&pretty"

There is the error message "waiting until all the Elastic nodes have the same version".
Did you check this aspect?


Hi zx8086,
Attached is the es version is running well. I'm not sure what is the fresh installation. I'm newbie :slight_smile:

Hi Roger,
I tried create the new node, but still same problem

@dat_nguyen

How many Elasticsearch Nodes do you have ? If it is one have you set this up correctly in the elasticsearch.yml file (Discovery-Type) ? Can you share that with us? Also check the indices:-

curl -X GET "http:// IP Address:9200/_cluster/health?pretty"

Hi zx8086,
please find attached. It seems there some errors :slight_smile:



Hello,

Please avoid posting screenshots, they are very hard to read, some people may not be able to see it at all and it is impossible to reproduce anything if it is needed, copy and share the texts using the preformatted text button (</>).

Hi leandrojmp,
I see, sorry for that, please find es.yml as below. Thank you so much

# ======================== Elasticsearch Configuration =========================
#
# NOTE: Elasticsearch comes with reasonable defaults for most settings.
#       Before you set out to tweak and tune the configuration, make sure you
#       understand what are you trying to accomplish and the consequences.
#
# The primary way of configuring a node is via this file. This template lists
# the most important settings you may want to configure for a production cluster.
#
# Please consult the documentation for further information on configuration options:
# https://www.elastic.co/guide/en/elasticsearch/reference/index.html
#
# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#
cluster.name: bfc_app
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
node.name: bfc-2
#
# Add custom attributes to the node:
#
#node.attr.rack: r1
#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
path.data: /var/lib/elasticsearch
path.repo: /home/dat/backup_kibana
# Path to log files:
#
path.logs: /var/log/elasticsearch
#
# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
#
bootstrap.memory_lock: true
#
# Make sure that the heap size is set to about half the memory available
# on the system and that the owner of the process is allowed to use this
# limit.
#
# Elasticsearch performs poorly when the system is swapping the memory.
#
# ---------------------------------- Network -----------------------------------
#
# By default Elasticsearch is only accessible on localhost. Set a different
# address here to expose this node on the network:
#
network.host: 192.168.0.113
# By default Elasticsearch listens for HTTP traffic on the first free port it
# finds starting at 9200. Set a specific HTTP port here:
#
http.port: 9200
#
# For more information, consult the network module documentation.
#
# --------------------------------- Discovery ----------------------------------
#
# Pass an initial list of hosts to perform discovery when this node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
#
discovery.seed_hosts: ["host1", "host2"]
discovery.type: single-node
# Bootstrap the cluster using an initial set of master-eligible nodes:
#
#cluster.initial_master_nodes: ["bfc-1"]
#
# For more information, consult the discovery and cluster formation module documentation.
#
# ---------------------------------- Various -----------------------------------
#

Comment out

as well as

and see if you can startup elasticsearch without any errors first.

Done, and start up es w/o errors

@dat_nguyen

I would review the TLS / SSL setup and enabled it.

If you restart everything works, you can enable http, if required and see if there is where the problem lies.

With the basic current security, you should be able start Kibana and see if you can move pass the initial error.

Also check your indices are all OK.

curl -X GET "http://:9200/_cluster/health?pretty"

There is still same problem wiht kibana server although I've changed es to basic security, and es indices es are okay. I attached some last kibana logs.

Your Elasticsearch cluster is Red.

It should be Green (or at least Yellow) to proceed.

Probably need to set your replicas to "0" or check the unassigned indices.

Set replicas to 0

I've tried:
