Elasticsearch & Kibana unattended installation

This section will explain how to install Elasticsearch and Kibana using an automated script. This script will perform a health check to verify that the system has enough resources to achieve an optimal performance. For more information, please visit the requirements section.


Root user privileges are required to run all the commands described below. To download the script the package curl will be used.

The script allows installing both Elasticsearch and Kibana. They can be installed either together or in separate machines. The available options to run the script are:



-e / --install-elasticsearch

Installs Elasticsearch (cannot be used together with option -k)

-k / --install-kibana

Installs Kibana (cannot be used together with option -e)

-n / --node-name

Name of the Wazuh server instance

-p / --elastic-password

Elastic user password

-c / --create-certificates

Generates the certificates for all the nodes indicated on the configuration file (only for multi-node mode)

-d / --debug

Shows the complete installation output

-i / --ignore-healthcheck

Ignores the health-check

-h / --help

Shows help

Installing Elasticsearch

Download the script and the configuration file. After downloading them, configure the installation and run the script. Choose the cluster mode between single-node or multi-node:

Download the script and the configuration file config.yml

# curl -so ~/elastic-stack-installation.sh https://raw.githubusercontent.com/wazuh/wazuh-documentation/4.0/resources/elastic-stack/unattended-installation/distributed/elastic-stack-installation.sh
# curl -so ~/config.yml https://raw.githubusercontent.com/wazuh/wazuh-documentation/4.0/resources/elastic-stack/unattended-installation/distributed/templates/config.yml

Configure the installation

Edit the ~/config.yml file to specify the IP you want the Elasticsearch service to bind to.


In order to create valid certificates for the communication between the various components of Wazuh and the Elastic Stack, external IPs must be used.

## Single-node configuration

## Elasticsearch configuration

network.host: <elasticsearch_ip>

## Certificates creation
- name: "filebeat"
  - "<wazuh_server_ip>"
- name: "kibana"
  - "<kibana_ip>"

In case of having more than one Wazuh servers, there can be specified as many fields as needed:

- name: "filebeat-X"
  - "<wazuh_server_ip_X>"

Run the script

  • To install Elasticsearch, run the script with the option -e and -n <node_name>:

# bash ~/elastic-stack-installation.sh -e -n <node_name>

After the installation, the script will prompt an output like this:

During the installation of Elasticsearch the passwords for its user were generated. Please take note of them:
Changed password for user apm_system
PASSWORD apm_system = Xf7bzEhl5fa9h3L0noyl

Changed password for user kibana_system
PASSWORD kibana_system = WyP1F5aCA8DHLwB14zOq

Changed password for user kibana
PASSWORD kibana = WyP1F5aCA8DHLwB14zOq

Changed password for user logstash_system
PASSWORD logstash_system = mA3OOfGjEYBYGB2DZt1Q

Changed password for user beats_system
PASSWORD beats_system = AeOqYqDsQ5CKqGP04eUv

Changed password for user remote_monitoring_user
PASSWORD remote_monitoring_user = DVxxnCyQTcOuv6h7c90H

Changed password for user elastic

Elasticsearch installation finished

Configuring Elasticsearch

Once Elasticsearch is installed, the script will start the services automatically. The certificates will be placed at ~/certs.zip. This file must be copied into the Wazuh server to extract the certificates needed.

In case that Kibana was installed in a different server, the certs.zip file should be also copied into its server to extract the corresponding certificates.

Installing Kibana

  1. Download the script. In case of installing Kibana on the same server as Elasticsearch, this step must me skipped:

    # curl -so ~/elastic-stack-installation.sh https://raw.githubusercontent.com/wazuh/wazuh-documentation/4.0/resources/elastic-stack/unattended-installation/distributed/elastic-stack-installation.sh
  2. Run the script:

    # bash elastic-stack-installation.sh -k n <node_name> -p <elastic_password>

    The following values must be replaced:

    • <node_name>: Name of the instance (this name must be the same used in config.yml for the certificate creation, e.g. kibana).

    • elastic_password: Password for the user elastic previously generated during the Elasticsearch installation.

  3. Access the web interface using the password generated during the Elasticsearch installation process:

    URL: https://<kibana_ip>
    user: elastic
    password: <PASSWORD_elastic>

    Upon the first access to Kibana, the browser shows a warning message stating that the certificate was not issued by a trusted authority. An exception can be added in the advanced options of the web browser or, for increased security, the root-ca.pem file previously generated can be imported to the certificate manager of the browser. Alternatively, a certificate from a trusted authority can be configured.

Configuring Kibana

If Kibana is accessed before installing the Wazuh server, the Wazuh Kibana plugin will indicate that it cannot establish a connection with the Wazuh API. Proceed with the Wazuh server installation to remediate this.

To uninstall Elasticsearch and Kibana, visit the uninstalling section.

Next steps

Once the Elastic Stack environment is ready, the Wazuh server can be installed. The Wazuh server installation guide can be found here.
