 +On one of the Elasticsearch nodes generate an access token for Kibana
 +<code bash>
 +/usr/share/elasticsearch/bin/elasticsearch-create-enrollment-token -s kibana
 +
 +eyJ2ZXIiOiI4LjYuMiIsImFkciI6WyIxMC42OC4xMDAuMTQ6OTIwMCJdLCJvZ3IoIoI0MzBhMWRiYWFhZGFmMjEzMjBiYzEyZTI5ZWM5NjhlOTNmZWQzMDA4YzgxMGMwYTY3NjMzOGYyZDY5NjE3OTAxIiwia2V5IjoiampEdXg0WUJtUDNfUFh6QlhVSWQ6WXJGMETtbV9ScWlqelZpMTJfckFpZyJ9

 +
 +On the Kibana node configure Kibana:
 +<code bash>
 +/usr/share/kibana/bin/kibana-setup
 +? Enter enrollment token: eyJ2ZXIiOiI4LjYuMiIsImFkciI6WyIxMC42OC4xMDAuMTQ6OTIwMCJdLCJvZ3IoIoI0MzBhMWRiYWFhZGFmMjEzMjBiYzEyZTI5ZWM5NjhlOTNmZWQzMDA4YzgxMGMwYTY3NjMzOGYyZDY5NjE3OTAxIiwia2V5IjoiampEdXg0WUJtUDNfUFh6QlhVSWQ6WXJGMETtbV9ScWlqelZpMTJfckFpZyJ9
 +
 +✔ Kibana configured successfully.
 +
 +To start Kibana run:
 +  bin/kibana
 +
 +</code>
 +
 +Get the elasticsearch.serviceAccountToken from ''/etc/kibana/kibana.yml''
 +<code yaml>elasticsearch.serviceAccountToken: AAEAAWVsYXN0aWMva2liYW5hL2Vucm9sbC1wcm9jZXNzLXRva2VuLTE2NzE3MTc2Njg4OTA6QllmZml2MGpTNjZzRTdnR1RCMXhRUQ</code>

 +Generate encryption keys ...

 +… and add all values to the kibana-keystore
 +<code bash>
 +/usr/share/kibana/bin/kibana-keystore add elasticsearch.serviceAccountToken
 +/usr/share/kibana/bin/kibana-keystore add xpack.encryptedSavedObjects.encryptionKey
 +/usr/share/kibana/bin/kibana-keystore add xpack.reporting.encryptionKey
 +/usr/share/kibana/bin/kibana-keystore add xpack.security.encryptionKey
 +</code>
 +remove the line with the ''elasticsearch.serviceAccountToken'' from ''/etc/kibana/kibana.yml''\\
 +
 +To be able to copy files between the ES nodes and Kibana a mount for the SMB share is needed.\\
 +Create a file containing the credentials for the share in the root user directory:
 +<code bash>
 +cat > /root/backup.crd
 +username=kenny
 +password=kennyspassword
 +<ctrl-d>
 +</code>
 +
 +To mount the share for the snapshot repository with the correct permissions for the elasticsearch user, we need to know the user id (uid) of the elasticsearch user:
 +''id -u elasticsearch''
 +''106''
 +
 +Create the mount directory
 +<code bash>
 +mkdir /mnt/backup
 +</code>
 +
 +Add the share used for repository in /etc/fstab\\
 +<code bash>
 +//10.0.1.10/ES       /mnt/backup     cifs    vers=3.0,credentials=/root/backup.crd,uid=106   0       0
 +</code>
 +
 +
 +Mount the share
 +<code bash>
 +mount //10.0.0.10/ES
 +</code>
 +
 +
 +
 +On one of the elasticsearch nodes\\
 +
 +Generate the SSL certificate and key for Kibana\\
 +<code bash>
 +/usr/share/elasticsearch/bin/elasticsearch-certutil cert -name deb11-elk-04_https -dns deb11-elk-04 -pem -self-signed</code>
 +
 +Tell to save it as ''deb11-elk-04_http.zip'' than copy it to the share:\\
 +<code bash>
 +cp /usr/share/elasticsearch/deb11-elk-04_http.zip /mnt/backup/debby/deb11-elk-04/
 +</code>
 +
 +Back to the Kibana node\\
 +Create the directory for the certificate and key
 +copy the certificate file, unzip it, move the certificate and key to the certs directory and clean up
 +<code bash>
 +mkdir /etc/kibana/certs
 +cd /etc/kibana/certs
 +cp /mnt/backup/debby/deb11-elk-04/deb11-elk-04_http.zip ./
 +unzip deb11-elk-04_http.zip
 +mv deb11-elk-04_https/* ./
 +rm -rf deb11-elk-04_https
 +rm deb11-elk-04_http.zip
 +chown -R root:kibana /etc/kibana/certs
 +</code>
 +
 +Allow Kibana to use HTTPS default port (443) ...
 +
 +Up to Kibana 8.14.x:
 +<code bash>
 +setcap cap_net_bind_service=+epi /usr/share/kibana/bin/kibana
 +setcap cap_net_bind_service=+epi /usr/share/kibana/bin/kibana-plugin
 +setcap cap_net_bind_service=+epi /usr/share/kibana/bin/kibana-keystore
 +setcap cap_net_bind_service=+epi /usr/share/kibana/node/bin/node
 +</code>
 +
 +Since Kibana 8.15:
 +<code bash>
 +setcap cap_net_bind_service=+epi /usr/share/kibana/bin/kibana
 +setcap cap_net_bind_service=+epi /usr/share/kibana/bin/kibana-plugin
 +setcap cap_net_bind_service=+epi /usr/share/kibana/bin/kibana-keystore
 +setcap cap_net_bind_service=+epi /usr/share/kibana/node/glibc-217/bin/node
 +</code>
 +
 +
 +
 +Install Kibana as service and start it
 +<code bash>
 +systemctl daemon-reload
 +systemctl enable kibana.service
 +
 +systemctl start kibana.service
 +</code>
 +
 +Kibana is now availbale at ''https://deb11-elk-04''\\
 +
 +Either use the generated password from the installation of ES or generate a new one on a ES node with 
 +<code bash>
 +/usr/share/elasticsearch/bin/elasticsearch-reset-password -u elastic
 +</code>
 +Login with elastic and the password
  
 +Kibana is installed
