Installation of LibreNMS on Ubuntu

In this tutorial, you will get some information on the installation of LibreNMS on Ubuntu 16.04.

In this tutorial, we will install and configure LibreNMS on Ubuntu 16.04 with an Alibaba Cloud Elastic Compute Service (ECS) instance.

Install LAMP Server

LibreNMS runs on the web server, written in PHP and uses MariaDB for database. So you will need to install Apache, PHP and MariaDB to your system.

First, install Apache and MariaDB by running the following command:

apt-get install apache2 mariadb-server -y

Once the installation is completed, start Apache and MariaDB service and enable them to start on boot:

systemctl start apache2
systemctl start mysql
systemctl enable apache2
systemctl enable mysql

By default, the latest version of PHP is not available in Ubuntu 16.04 default repository. So you will need to add the repository for that. You can add it by running the following command:

apt-get install software-properties-common -y
add-apt-repository ppa:ondrej/php

Next, update the repository and install PHP along with all the libraries by running the following command:

apt-get install libapache2-mod-php7.1 php7.1-cli php7.1-mysql php7.1-gd php7.1-snmp php-pear php7.1-curl snmp graphviz php7.1-mcrypt php7.1-json fping imagemagick whois mtr-tiny nmap python-mysqldb snmpd php-net-ipv4 php-net-ipv6 rrdtool git -y

Once all the packages are installed, enable required PHP modules with the following command:

phpenmod mcrypt
a2enmod php7.1
a2dismod mpm_event
a2enmod mpm_prefork

Next, you will also set Time Zone in php.ini file:

nano /etc/php/7.1/cli/php.ini

Make the following changes:

date.time = Asia/Kolkata

Save and close the file. And then you can configure MariaDB, download LibreNMS, configure apache for LibreNMS and access LibreNMS web installation Wizard following the step by step tutorial.
