In this tutorial, we will install and configure LibreNMS on Ubuntu 16.04 with an Alibaba Cloud Elastic Compute Service (ECS) instance.
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 -yOnce 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 mysqlBy 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/phpNext, 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 -yOnce all the packages are installed, enable required PHP modules with the following command:
phpenmod mcrypt
a2enmod php7.1
a2dismod mpm_event
a2enmod mpm_preforkNext, you will also set Time Zone in php.ini file:
nano /etc/php/7.1/cli/php.iniMake the following changes:
date.time = Asia/KolkataSave 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.
Caching allows us to store data in RAM so that data can be served faster, without any needing to query the database or process any PHP.
Whilst this is a great start, what will happen if your website suddenly starts to receive lots of concurrent visitors? While the stack we have installed is performant, how can we improve it, to ensure that no matter how popular our site becomes our server won't choke?
The answer to our problem is caching. Caching allows us to store data in RAM so that any future request for that data can be served faster, without any needing to query the database or process any PHP.
