LibreNMS is a flexible and robust monitoring system that can be used to monitor a variety of devices on a network. In this tutorial, we will show you how to install LibreNMS on a Fedora Server Latest system.

Steps:

Update the system.
```
sudo dnf upgrade -y
```

Install required packages.

sudo dnf install epel-release git cronie fping ImageMagick jwhois mariadb mariadb-server mtr MySQL-python net-snmp net-snmp-utils nginx nmap php php-cgi php-common php-fpm php-gd php-mbstring php-mysqlnd php-process php-snmp unzip

sudo systemctl enable cronie mariadb nginx php-fpm
sudo systemctl start cronie mariadb nginx php-fpm

Set MariaDB root password and create LibreNMS database.

sudo mysql_secure_installation
sudo mysql -u root -p
CREATE DATABASE librenms CHARACTER SET utf8 COLLATE utf8_general_ci;
GRANT ALL PRIVILEGES ON librenms.* TO 'librenms'@'localhost' IDENTIFIED BY '<password>';
FLUSH PRIVILEGES;
EXIT;

Replace <password> with a secure password.

Configure PHP.

sudo cp /etc/php.ini /etc/php.ini.bak
sudo sed -i 's|^;date.timezone =|date.timezone = UTC|' /etc/php.ini
sudo sed -i 's|^memory_limit = 128M|memory_limit = 512M|' /etc/php.ini
sudo sed -i 's|^;max_execution_time = 30|max_execution_time = 300|' /etc/php.ini
sudo systemctl restart php-fpm

Create a new LibreNMS user and group.

sudo useradd librenms -d /opt/librenms -M -r
sudo usermod -a -G librenms nginx

Clone the LibreNMS repository.

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

Install LibreNMS dependencies.

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

Set permissions and ownership.

sudo chown -R librenms:librenms /opt/librenms
sudo chmod 770 /opt/librenms/bootstrap/cache /opt/librenms/storage
sudo setfacl -d -m g::rwx /opt/librenms/bootstrap/cache /opt/librenms/storage
sudo setfacl -R -m g::rwx /opt/librenms/bootstrap/cache /opt/librenms/storage

Set up Nginx virtual host.

sudo nano /etc/nginx/conf.d/librenms.conf

Configure the virtual host file with the following content.

server {
  listen 80;
  server_name <server_name>;

  root /opt/librenms/html;
  index index.php;

  access_log /var/log/nginx/librenms_access.log;
  error_log /var/log/nginx/librenms_error.log;

  location / {
    try_files $uri $uri/ /index.php?$query_string;
  }

  location ~ \.php$ {
    fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
    fastcgi_index index.php;
    include fastcgi_params;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    fastcgi_param PHP_VALUE "upload_max_filesize = 10M \n post_max_size= 10M";
    fastcgi_param PATH_INFO $fastcgi_script_name;
  }
}

Replace <server_name> with the actual server name.

Apply the changes.

sudo nginx -t
sudo systemctl restart nginx

Set up LibreNMS.

sudo cp /opt/librenms/.env.example /opt/librenms/.env

Replace <server_name> with the actual server name and <password> with the previously set database password.

Run the installation script.
```
sudo /opt/librenms/scripts/setup.php
```
Log in to LibreNMS.

Open your web browser and go to http://<server_name> to access LibreNMS. Log in with the default username admin and password admin.
