I am setting up a LAMP server on my VPS which runs Ubuntu 16.04
The main use of the server will be to serve as a backend for a web application. The Apache will host the PHP files and the mySQL will host the data (testing environment).
I am following the following link to install the required https://www.linode.com/docs/websites/lamp/install-lamp-on-ubuntu-16-04 and in it there is a part where a VIRTUAL HOST is created.
My question is that, is it necessary to create a virtual host if only 1 site will run on the device?
