How to Install LibreNMS on FreeBSD Latest

In this tutorial, we will go over the steps to install LibreNMS on FreeBSD Latest. LibreNMS is a network monitoring tool that allows you to track and monitor network devices and services.

Prerequisites

Before we begin, you will need the following:

  1. A FreeBSD Latest server with root privileges
  2. Internet connectivity
  3. A valid email address

Step 1 – Update Packages

First, we need to ensure that the software packages installed on the system are current. We can do that by running the following command:

pkg update && pkg upgrade

Step 2 – Install Required Packages

LibreNMS requires several packages to be installed on your FreeBSD Latest system. These packages include PHP, MySQL, Nginx or Apache, and SNMP:

pkg install php73 php73-extensions php73-mysqli php73-snmpd nginx mysql57-server net-snmp

Step 3 – Create a MySQL Database

Next, we need to create a MySQL database for LibreNMS. We can do that by running the following commands:

service mysql-server start
mysqladmin -uroot create librenmsdb
mysql -uroot -p

When prompted for the password, enter your MySQL root password. Then, run the following commands to grant permissions to a user we will create in the next step:

GRANT ALL PRIVILEGES ON librenmsdb.* TO 'librenmsuser'@'localhost' IDENTIFIED BY 'password';
FLUSH PRIVILEGES;
exit

Replace librenmsuser and password with your own preferred username and password.

Step 4 – Download and Install LibreNMS

Next, we will download and install LibreNMS by following these steps:

  1. Download the latest LibreNMS release using the following command:

    fetch https://github.com/librenms/librenms/archive/21.9.0.tar.gz -o /tmp

    Replace 21.9.0 with the latest release version.

  2. Extract the downloaded archive:

    tar zxvf /tmp/21.9.0.tar.gz -C /usr/local/www

  3. Rename the extracted folder:

    mv /usr/local/www/librenms-21.9.0 /usr/local/www/librenms

  4. Change ownership of the installation directory:

    chown -R www:www /usr/local/www/librenms

Step 5 – Configure Nginx

If you installed Nginx, you will need to configure it to work with LibreNMS. We can do that by creating a new server block configuration in Nginx:

  1. Open the Nginx configuration file for editing:

    vi /usr/local/etc/nginx/nginx.conf

  2. Add the following configuration to the end of the file:

    server {
    listen 80;
    server_name your_server_name;
    root /usr/local/www/librenms;
    index index.php;
    #access_log /var/log/nginx/access.log main;
    location / {
         try_files $uri $uri/ /index.php?$query_string;
    }
    location ~ .php$ {
         fastcgi_pass unix:/var/run/php-fpm.sock;
         fastcgi_index index.php;
         fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
         include fastcgi_params;
   }
}

    Replace your_server_name with your server's hostname.

  3. Save and close the file.

Step 6 – Configure LibreNMS

Next, we will configure LibreNMS to use the MySQL database we created earlier:

  1. Copy the default configuration file:

    cp /usr/local/www/librenms/config.php.default /usr/local/www/librenms/config.php

  2. Open the configuration file for editing:

    vi /usr/local/www/librenms/config.php

  3. Change the following lines to match your MySQL configuration:

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

    Replace librenmsuser and password with the MySQL user and password that you created.

  4. Save and close the file.

Step 7 – Install LibreNMS Dependencies

LibreNMS has several dependencies that need to be installed. We can do that by running the following command:

cd /usr/local/www/librenms
./scripts/composer_wrapper.php install --no-dev

Step 8 – Run LibreNMS Discovery and Poller

Finally, we need to run Discovery and Poller by executing the following commands:

/usr/local/bin/php /usr/local/www/librenms/discovery.php -u
/usr/local/bin/php /usr/local/www/librenms/poller.php -h all

Step 9 – Access the LibreNMS Web Interface

Now that the installation of LibreNMS is complete, you can access the web interface by visiting http://your_server_name in a web browser. Replace your_server_name with the hostname of your FreeBSD Latest server.

You will be prompted to create a new user account. Once you have created the account, you can start monitoring your network devices and services from the LibreNMS dashboard.

Congratulations, you have successfully installed LibreNMS on FreeBSD Latest!
