This section will explain how to install Wazuh on a single host by using a script that will automatically detect whether the operating system uses
The script will perform a health-check verifying that the available system resources meet the minimal requirements. 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.
Download and run the script:
# curl -so ~/all-in-one-installation.sh https://raw.githubusercontent.com/wazuh/wazuh-documentation/4.1/resources/elastic-stack/unattended-installation/all-in-one-installation.sh && bash ~/all-in-one-installation.sh
The script will perform a health-check to ensure that the host has enough resources to guarantee the proper performance. This can be skipped adding the option
--ignore-healthcheckwhen running the script.
After the execution of the script, it will show the following messages to confirm that the installation was successful. Save the password for the
elasticuser since this will be needed to access Kibana:

Access the web interface using the password generated during the installation process:
URL: https://<wazuh_server_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.pemfile previously generated can be imported to the certificate manager of the browser. Alternatively, a certificate from a trusted authority can be configured.
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. It means that Kibana can be accessed from the outside and will accept all the available IPs of the host. This value can be changed for a specific IP if needed.
To uninstall all the components of the all in one installation, visit the uninstalling section.
Once the Wazuh environment is ready, a Wazuh agent can be installed on every endpoint to be monitored. The Wazuh agent installation guide is available for most operating systems and can be found here.
