Error: ENOENT: no such file or directory, open 'config/kibana-server.key'

I have an issue about setting up basic security for the Elastic Stack plus secured HTTPS traffic when I try to set on kibana.yml.
Elastic is working and reachable over https but I receive an error are as follow when I try to start kibana;

I stucked and didnt understand why this is happened.

journalctl -u kibana

FATAL Error: ENOENT: no such file or directory, open 'config/kibana-server.key'

and also got more details when I allow root priviledge;

Sorry by the way, I forgot the add "kibana.service" content.

The obvious (most likely) answer is that the config/kibana-server.key file, which you reference here:

doesn't exist.

What files are there in your kibana config/ directory?
Are you 100% sure that this file exists with exactly that name?

Hey TimV,

I have 3 files in it. I am looking at it.


I used an absolute path rather than a relative path after this kind of problem for solving.

server.ssl.enabled: true
server.ssl.certificate: /etc/kibana/config/kibana-server.csr
server.ssl.key: /etc/kibana/config/kibana-server.key

and Journal output has changed ;

FATAL  Error: error:0909006C:PEM routines:get_name:no start line

Is that really a CSR (certificate signing request)? If so, it's not actually a certificate, and this setup isn't going to work.

I didnt understand what you mean exactly?

let me explain What I did. and please tell me What I missed or did I wrong something?
But please don't tell me everything is wrong :frowning:

  • generate a CA using "bin/elasticsearch-certutil ca" : [output: elastic-stack-ca.p12]
  • Generate private certificate using "bin/elasticsearch-certutil cert --ca elastic-stack-ca.p12" :[Output: elastic-certificate.p12]
  • I added transport layer config set in elasticsearch.yml

used certificate tool to generate a CSR for encrypt HTTP client comm. for elastic ;(I didnt generate new CA. I used old one)

  • "bin/elasticsearch-certutil http" referred elastic-stack-ca.p12 as CA
  • enter validate period as 5y, generated 2 certificates for 2 nodes with node-name and IP addresses
  • unzip generated "" file and exracted 2 files(http.p12, elasticsearch-ca.pem)
  • added 2 lines in elasticsearch.yml true http.p12
  • and also confgured Kibana to trust elasticsearch CA for the http layer
    elasticsearch.ssl.certificateAuthorities: /etc/kibana/config/elasticsearch-ca.pem

last thing I did are as follow;

generated a server certificate and private key, using following line;
./bin/elasticsearch-certutil csr -name kibana-server

  • unzip generated "" file and exracted 2 files (kibana-server.csr, kibana-server.key)
  • added 2 lines in kibana.yml
    server.ssl.certificate: /etc/kibana/config/kibana-server.crt
    server.ssl.key: /etc/kibana/config/kibana-server.key
  • and also added
    server.ssl.enabled: true
