How to setup LibreNMS?

Setting up LibreNMS involves several steps, but I'll provide you with a high-level overview of the process. Keep in mind that specific details may vary based on your operating system and environment. Here's a general outline to get you started:

System Requirements:
- Ensure that your server meets the minimum system requirements, which typically include PHP, MySQL, Apache/Nginx, and other necessary dependencies.
Install Required Software:
- Install the required software packages, such as PHP, MySQL (or MariaDB), Apache (or Nginx), and SNMP on your server.
Create a Database:
- Set up a database for LibreNMS to store its data. You'll need to create a new MySQL/MariaDB database and a dedicated user account with appropriate permissions.
Download LibreNMS:
- Download the latest version of LibreNMS from the official GitHub repository or use the provided installation script.
Install Dependencies:
- Install the required PHP dependencies and libraries using Composer, a PHP package manager. This will be necessary for LibreNMS to function properly.
Configure Web Server:
- Set up the web server (Apache or Nginx) to serve the LibreNMS web interface. You'll need to create a virtual host pointing to the LibreNMS installation directory.
Run the Installer:
- Run the LibreNMS installation script. This will guide you through the initial setup process, including database configuration and user account creation.
Add Devices for Monitoring:
- After the installation, log in to the LibreNMS web interface. Begin adding network devices that you want to monitor. You can do this manually or use the auto-discovery feature to find devices on your network.
Configure Pollers and Collectors:
- Fine-tune the polling and data collection settings based on your network size and requirements. Adjust polling intervals and data retention periods as needed.
Set Up Alerts and Notifications:
- Configure alerting rules based on performance thresholds or specific conditions. Set up notification methods (e.g., email, SMS) for alert delivery.
Explore the Web Interface:
- Take some time to explore the LibreNMS web interface, which provides various dashboards, graphs, and tools for monitoring and managing your network.
Regular Maintenance:
- Schedule regular maintenance tasks, such as updating LibreNMS to the latest version, backing up your database, and monitoring system health.
