Apache is the most prevalent web server operating on the internet and there’s good reason for this. It’s robust, secure, stable and easy to configure with a myriad of add-ons (mods) to allow you to set up websites running PHP, Java and Ruby amongst many other uses such as a reverse proxy or web application firewall. Getting a website up and running is very easy with Apache as all Linux distributions give you access to Apache using the distributions installation tools such as Yum (Red Hat based) or apt (Debian based).
