The Domain Name Service (or DNS) is the key to the presence of your server on the internet. You are probably aware your domain has an “IP” address, which stands for Internet Protocol; that number is your domain’s literal web address on the internet.

How To Install the LAMP Stack on CentOS 7

Reading Time: 4 minutesWhether you’re new to hosting websites or a seasoned developer, you’ve more than likely heard of a LAMP stack. The LAMP stack is the base set of applications that most websites running on a Linux server are served from and is commonly referred to as “Lamp”.

Throughout this article, we’ll walk through installing the LAMP stack on your CentOS 7 server so you can run a website from any Dedicated Server or Virtual Private Server. Although we’re focusing on installing LAMP on a CentOS 7 server, the steps that we’ll cover are very similar across multiple Linux distributions.
