LibreNMS is a free and open-source network monitoring system. It is used to monitor network devices including servers, routers, switches, etc. In this tutorial, we will learn how to install LibreNMS on OpenSUSE latest.
Before start, make sure that you have the following prerequisites:
Before installing any software, it is recommended to update the system first. To do so, run the following command in the terminal:
sudo zypper update
Some packages are required for the installation of LibreNMS. Install these packages using the following command:
sudo zypper install apache2 mariadb mariadb-client mariadb-server net-snmp net-snmp-utils fping whois git graphviz ImageMagick
Log in to the MariaDB shell by running the following command:
sudo mysql -u root -p
Create a database named "librenms" by running the following command:
MariaDB [(none)]> create database librenms;
Create a new user named "librenms" and grant all privileges on the "librenms" database:
MariaDB [(none)]> grant all privileges on librenms.* to 'librenms'@'localhost' identified by 'password';
Flush the privileges and exit from the MariaDB shell:
MariaDB [(none)]> flush privileges;
MariaDB [(none)]> exit;
Clone the LibreNMS repository by running the following command:
sudo git clone https://github.com/librenms/librenms.git /opt/librenms
Change the permission of the cloned directory:
sudo chown -R wwwrun:www /opt/librenms
sudo chmod -R 775 /opt/librenms
Change the directory to the librenms directory and run the following command to install the dependencies:
cd /opt/librenms
sudo ./scripts/composer_wrapper.php install --no-dev
Create the configuration file by copying the example configuration file:
sudo cp /opt/librenms/.env.example /opt/librenms/.env
Edit the configuration file using a text editor of your choice:
sudo nano /opt/librenms/.env
Set the database connection details:
DB_HOST=localhost
DB_NAME=librenms
DB_USER=librenms
DB_PASS=password
Save the file and exit.
Generate the application key:
sudo php /opt/librenms/artisan key:generate
Run the following command to set up the web server and PHP:
sudo /opt/librenms/scripts/setup_oss_suse.sh
Restart the Apache web server:
sudo systemctl restart apache2
LibreNMS is now installed and can be accessed through a web browser. Open a web browser and enter the following URL:
http://server-ip-address/librenms
Replace server-ip-address with your server’s IP address.
