Elasticsearch & Kibana unattended installation

This section will explain how to install Open Distro for Elasticsearch and Open Distro for 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. This script uses the Search Guard offline TLS tool to create the certificates.


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 Open Distro for Elasticsearch (cannot be used together with option -k)

-k / --install-kibana

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

-n / --node-name

Indicates the name of the instance

-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 Open Distro for 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/open-distro/unattended-installation/distributed/elastic-stack-installation.sh
# curl -so ~/config.yml https://raw.githubusercontent.com/wazuh/wazuh-documentation/4.0/resources/open-distro/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>

# Clients certificates
  - name: admin
    dn: CN=admin,OU=Docu,O=Wazuh,L=California,C=US
    admin: true
  - name: filebeat
    dn: CN=filebeat,OU=Docu,O=Wazuh,L=California,C=US

# Kibana-instance
- <kibana_ip>

# Wazuh-master-configuration
- <wazuh_master_server_IP>

In case of having more than one Wazuh server, there can be added as many nodes as needed, changing the name of the certificate and the CN value. This should be indicated on the Clients certificates section:

- name: filebeat-X
  dn: CN=filebeat-x,OU=Docu,O=Wazuh,L=California,C=US

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>


The Open Distro for Elasticsearch performance analyzer plugin is removed during the installation since it may have a negative impact on system resources.

Configuring Elasticsearch

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

In case Kibana will be installed in a different server, the certs.tar 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 Open Distro for Elasticsearch, this step must be skipped:

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

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

    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).

  3. Access the web interface:

    URL: https://<kibana_ip>
    user: admin
    password: admin

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.


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.

Configuring Kibana

It is highly recommended to change Elasticsearch’s default passwords for the users found at the /usr/share/elasticsearch/plugins/opendistro_security/securityconfig/internal_users.yml file. More information about this process can be found here.

Once Kibana is running it is necessary to assign each user its corresponding role. To learn more visit the Setting up the Wazuh Kibana plugin section.

If you need 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.
