Never started node but got ERROR: Skipping security auto configuration because it appears that security is already configured

Elastic Stack Elasticsearch
1

I got token from already running master node with following command

bin\elasticsearch-create-enrollment-token -s node

I ran other node that I've never strated

bin\elasticsearch --enrollment-token <enrollment-token>

but I got this error message

ERROR: Skipping security auto configuration because it appears that security is already configured.

I've never ran this node but It keep saying I did and sudo rm -rf /var/lib/elasticsearch/nodes doesn’t help

I set inbound rule in AWS like:

IPv4	HTTPS	TCP	443	0.0.0.0/0	

IPv4	SSH	TCP	22	0.0.0.0/0	

IPv4	HTTP	TCP	80	0.0.0.0/0	

IPv4        custom TCP	TCP	9200 - 9399	0.0.0.0/0	

IPv6	custom  TCP	TCP	9200 - 9399	::/0

and I set master node on my instatce following these steps:

#1
sudo yum install -y java-1.8.0-openjdk-devel.x86_64

#2
sudo rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch

#3 
sudo nano /etc/yum.repos.d/elasticsearch.repo

#4 save these lines on elasticsearch.repon

sudo systemctl start elasticsearch

then I stopped master node, started again with command ./bin/elasticsearch -d and I got this log

I installed second node following exactly same step I used when installing master node except running node and setting password

what's wrong with this

There's really no need to do step 6 above, installing the packaged version of Elasticsearch will ensure that permissions and ownership for directories and files are correct.

Did you configure Elasticsearch before you ran this command?
Ideally, your elasticsearch.yml should be the default one with no changes, as the enrollment process will bootstrap everything it needs to join the cluster.

you mean I should not change application.yml before first running second node with token?

also I would appreciate if you confirm what I understood is right

steps for setting es on ec2

  1. install es on first ec2 instance
  2. change elasticsearch.yml for master node
  3. run master node
  4. install es on second ec2 instatce
  5. run second node with token published from master node
  6. change second node's config file

I'm running es on private IP, not localhost

You got this error message

ERROR: Skipping security auto configuration because it appears that security is already configured.

Because your 2nd node has explicit configuration for xpack.security.enabled

xpack.security.enabled: true

It also has a bunch of other security related settings which are not necessary as they will be auto-configured with the enrollment token. Please refer to this doc section for details.
