LibreNMS is an open-source, community-driven network monitoring system that aims to provide a comprehensive solution for monitoring a wide range of devices and applications. This tutorial will guide you through the steps required to install LibreNMS on nixOS Latest.
Before proceeding with this tutorial, make sure you have the following:
Open your terminal and update your nixOS system by running the following command:
sudo nix-channel --update
sudo nixos-rebuild switch
Now, install the required packages for LibreNMS by executing the following command:
sudo nix-env -iA nixos.php nixos.composer nixos.mariadb
Create a directory where you want to install LibreNMS and navigate to it:
sudo mkdir /opt/librenms
cd /opt/librenms
Now, download the latest version of LibreNMS using Git by running the following command:
sudo git clone https://github.com/librenms/librenms.git .
Set the correct permissions for the LibreNMS directory:
sudo chown -R www-data:www-data /opt/librenms
sudo chmod 777 /opt/librenms/bootstrap/cache /opt/librenms/storage
Install the required PHP dependencies using Composer:
sudo composer install --no-dev
Next, we need to configure the database for LibreNMS. To do this, log in to the MariaDB server:
sudo mariadb -u root -p
Create a new database and user for LibreNMS:
CREATE DATABASE librenms CHARACTER SET utf8 COLLATE utf8_general_ci;
CREATE USER 'librenms'@'localhost' IDENTIFIED BY 'your-password';
GRANT ALL PRIVILEGES ON librenms.* TO 'librenms'@'localhost' IDENTIFIED BY 'your-password';
FLUSH PRIVILEGES;
exit
Open the PHP configuration file in your favorite text editor:
sudo nano /etc/php.ini
Add the following lines to the end of the file:
date.timezone = America/New_York
memory_limit = 512M
cgi.fix_pathinfo=0
Save and close the file.
Create a new Apache configuration file for LibreNMS:
sudo nano /etc/httpd/conf.d/librenms.conf
Add the following configuration:
<VirtualHost *:80>
ServerName librenms.example.com
DocumentRoot /opt/librenms/html/
<Directory "/opt/librenms/html/">
AllowOverride All
Options FollowSymLinks MultiViews
Require all granted
</Directory>
</VirtualHost>
Save and close the file.
Enable and start the required services:
sudo systemctl enable mariadb
sudo systemctl start mariadb
sudo systemctl enable php-fpm
sudo systemctl start php-fpm
sudo systemctl enable httpd
sudo systemctl start httpd
Now, open your web browser and navigate to http://librenms.example.com/install.php to complete the installation.
Follow the on-screen instructions to set up LibreNMS, including connecting to the database and setting up the administrator account.
Once the installation is complete, delete the install.php file:
sudo rm /opt/librenms/html/install.php
Finally, navigate to http://librenms.example.com/ to access your LibreNMS dashboard.
Congratulations! You have successfully installed LibreNMS on nixOS Latest.
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!
