In this article, we will be discussing how to install Multiple PHP Versions on Ubuntu 16.04. Ubuntu 16.04 LTS servers assign the PHP 7.0 version by default. Although PHP 5.6 is currently EOL (end of life) as of December of 2018, some applications may not be compatible with PHP 7.0. For this tutorial, we instruct on how to switch between PHP 7.0 and PHP 5.6 for Apache and the overall default PHP version for Ubuntu.

Introduction

SNMP, or Simple Network Management Protocol, is widely used to communicate with and monitor network devices, dedicated servers, and more, all via IP. In this case, we'll be installing an SNMP agent on a CentOS VPS server, which will allow for collection of data from our server, and make the information available to a remote SNMP manager.

The Node Version Manager (NVM) is a command-line utility used to manage and switch between multiple active versions of Node.js on a single system. Whether you’re an admin or a developer, being able to change the javascript runtime environment on your system simplifies testing applications across different versions.

Sometimes during a software install, things can go sideways and you realize that not all the program downloaded or the installation was interrupted for some reason leaving you with incomplete files and empty directories. Honestly, this is a rare occurrence but it can happen from time to time. This then begs the question; So how do I completely uninstall recently installed software? In this tutorial, we’ll be safely removing PostgreSQL from our Liquid Web Ubuntu VPS server.  

PostgreSQL (pronounced "post-gress-Q-L") is a household name for open source relational database management systems. Its object-relational meaning that you’ll be able to use objects, classes in database schemas and the query language. As part of our PostgreSQL series, we’ll show you how to list and switch between databases quickly.
