Unattended installation

You can install Wazuh on a single host by using a script that automatically detects whether the operating system uses rpm or deb packages. The script performs a health check to verify that the available system resources meet the minimal requirements. For more information, check the Requirements section.

The script installs some packages, including unzip and libcap, required by Open Distro for Elasticsearch.

Installing Wazuh

Note

Root user privileges are required to run all the commands. The curl package is used to download the script.

  1. Run the following command:

    # curl -so ~/unattended-installation.sh https://packages.wazuh.com/resources/4.2/open-distro/unattended-installation/unattended-installation.sh && bash ~/unattended-installation.sh

    The script performs a health check to ensure that the host has enough resources to guarantee proper performance. To skip this step, add the -i or --ignore-healthcheck option when running the script.

    After executing the script, the output prompts all the users' passwords and a message confirms that the installation was successful.

 11/17/2021 09:09:20 INFO: You can access the web interface https://<kibana_ip>. The credentials are wazuh:kFadROYxhYtdf9xIj1DLJCPv17cEC5aA

  2. Access the web interface:

URL: https://<wazuh_server_ip>
user: wazuh
password: <wazuh_user_password>

On the first access to Kibana, the browser displays a warning message indicating that the certificate was not issued by a trusted authority. It is possible to add an exception in the browser's advanced options or, for increased security, the previously generated root-ca.pem file can be imported into the certificate manager of the browser. Alternatively, it is possible to configure a certificate from a trusted authority.

Note

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

Customizing the installation

The Kibana configuration found at the /etc/kibana/kibana.yml file has the server.host parameter set to 0.0.0.0. This means that Kibana can be accessed from the outside and accepts all the available IP addresses of the host. This value can be changed for a specific IP address if needed.

To uninstall the components of the all-in-one installation, you can use the option -r / --uninstall to remove all the components installed.

Next steps

Once the Wazuh environment is ready, a Wazuh agent can be installed on every endpoint to be monitored. To learn how to install agents, check the Wazuh agent section.
