How to Configure Multiple Sites with Apache

Reading Time: 2 minutes

If you are hosting more than one site on a server, then you most likely use Apache’s virtual host files to state which domain should be served out. Name based virtual hosts are one of the methods used to resolve site requests. This means that when someone views your site the request will travel to the server, which in turn, will determine which site’s files to serve out based on the domain name. Using this method you’ll be able to host multiple sites on one server with the same IP. In this tutorial, we’ll show you how to set up your virtual host file for each of your domains on an Ubuntu 18.04 server. Continue reading “How to Configure Multiple Sites with Apache”

This provides and extra layer of protection against common threats a server faces. This article will explore the installation of mod_security along with the CRS (Core Rule Set) in a Ubuntu 16.04 LTS Server running Apache 2.4.

An Introduction to Firewalld

Reading Time: 5 minutes

There are, for the most part, no long series of chains, jumps, accepts and denies that you need to memorize in order to get firewalld up and running in a basic configuration. The rules are simple and straightforward, but there is no reason you cannot still have all the power that iptables afforded. Continue reading “An Introduction to Firewalld”
