Installing LibreNMS on NetBSD

LibreNMS is a popular open-source network monitoring and alerting tool. In this tutorial, we will be learning how to install LibreNMS on NetBSD.

Prerequisites

Before we begin the installation process, it is recommended that you have the following:

• A running instance of NetBSD
• A user account with administrative privileges
• A stable internet connection

Installing LibreNMS

1. Update the package database to ensure that you are installing the latest version of LibreNMS.

sudo pkgin update

2. Install and enable the necessary PHP modules. LibreNMS requires a few PHP modules to function correctly, including gd, pdo, and pdo_mysql.

sudo pkgin install php74-gd php74-pdo php74-pdo_mysql

3. Install the SNMP daemon, which is required for LibreNMS to monitor network devices.

sudo pkgin install net-snmp

4. Clone the LibreNMS repository from GitHub.

git clone https://github.com/librenms/librenms.git /opt/librenms

5. Change the owner and group of the LibreNMS directory to the default web server user.

sudo chown -R www:www /opt/librenms

6. Navigate to the LibreNMS directory and install the required dependencies.

cd /opt/librenms
sudo ./scripts/composer_wrapper.php install --no-dev

7. Generate a new config file and set the database credentials.

cp config.php.default config.php
nano config.php

8. Uncomment the following line and update it with your database credentials.

$config['db_host'] = 'localhost';
$config['db_user'] = 'librenms';
$config['db_pass'] = 'password';
$config['db_name'] = 'librenms';

9. Generate a new authentication token for your installation.

php /opt/librenms/build_token.php

10. Set up the database and the required cron jobs.

sudo /usr/pkg/bin/mysql -u root -p < /opt/librenms/db_schema_mysql.sql
sudo echo '*/5 * * * * www /usr/pkg/bin/php /opt/librenms/cronic /opt/librenms/poller-wrapper.py 16' >> /etc/crontab
sudo echo '0 0 * * * www /usr/pkg/bin/php /opt/librenms/cronic /opt/librenms/daily.sh' >> /etc/crontab
sudo echo '*/5 * * * * www /usr/pkg/bin/php /opt/librenms/cronic /opt/librenms/alerts.php' >> /etc/crontab

11. Start the web server and navigate to http://localhost/librenms to access your installation.

sudo chown -R www:www /opt/librenms/bootstrap/cache
sudo chown -R www:www /opt/librenms/storage
sudo rcctl start httpd

Congratulations! You have successfully installed LibreNMS on NetBSD. You can now start monitoring and managing your network devices using this powerful open-source tool.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!

Alternatively, for the best virtual desktop, try Shells!
