Wazuh is a powerful open-source SIEM and security monitoring platform. In this article, I’ll walk you through the fastest way to install Wazuh 4.12 on an Ubuntu-based server using the official installation script.

✅ Update Your System First

Before installing any software, it’s always best practice to update your system packages:

sudo apt-get update
sudo apt-get dist-upgrade -y

This ensures your server is running the latest packages and avoids compatibility issues during the installation.

⚙️ Run the Wazuh 4.12 All-in-One Installer

The Wazuh team provides a script that automates the installation of all core components. Run the command below:

curl -sO https://packages.wazuh.com/4.12/wazuh-install.sh && sudo bash ./wazuh-install.sh -a

This command will:

• Install all necessary dependencies
• Deploy Wazuh Manager, Wazuh Indexer, Filebeat, and the Wazuh Dashboard
• Automatically configure services for basic use

🔐 Important: Don’t Forget the Admin Credentials

Once the installation is complete, the Wazuh Dashboard login details (admin username and password) will be shown only once in your terminal.

👉 Be sure to save or note this password securely — you won’t be able to see it again.

🌐 Accessing the Web Interface

After installation, open your browser and navigate to:

https://<your-server-ip>

Use the admin credentials displayed at the end of the installation process to log in.
