At least two servers are required for interaction settings. One for the Master and one for the node. All nodes are configured in the same way.

Introduction

In this article we will learn what the Network Time Protocol (NTP) is and how to install it on the two Linux distributions most commonly used on Liquid Web’s servers. We will be focusing on using CentOS 7 and Ubuntu 18.04 servers, but the process is largely the same on other recent versions of each. Before we start, make sure we are familiar with using SSH (Secure Shell) as we’ll need it to connect to the server. Here’s a link to one of our articles on the basics of SSH if you are unfamiliar with its usage.
