Elasticsearch is not starting for Search Guard error

Elastic Stack Elasticsearch
1

I'm trying to configure Search Guard admin. here is my elasticsearch.yml configurations:

searchguard.ssl.transport.pemcert_filepath: /home/rsa-key-20200528/search-guard-ssl-master/example-pki-scripts/node-0.crt.pem
searchguard.ssl.transport.pemkey_filepath: /home/rsa-key-20200528/search-guard-ssl-master/example-pki-scripts/node-0.key.pem
searchguard.ssl.transport.pemkey_password: changeit
searchguard.ssl.transport.pemtrustedcas_filepath: /home/rsa-key-20200528/search-guard-ssl-master/example-pki-scripts/ca/root-ca.pem
searchguard.ssl.transport.enforce_hostname_verification: false

searchguard.authcz.admin_dn:
  - CN=kirk,OU=client,O=client,L=Test,C=DE

After this configurations, I'm unable to start my elasticsearch. Here is half of full error from my "/var/log/elasticsearch/my-application.log" file. I can't post full for character limitations.

I'm following this and this documentation.

what is wrong here? why elasticsearch is not starting?

I would recommend you contact the Searchguard community about this.

Judging from the error message it seems the location of your certificates is:

/home/rsa-key-20200528/search-guard-ssl-master/example-pki-scripts/node-0.crt.pem

However, the docs state that all certificates

must be under the config/ directory, specified using a relative path (mandatory)

(Configuring TLS | Security for Elasticsearch | Search Guard)

Please try moving the certificates and key(s) in the config directory.
