Java remains an enduring and versatile language in programming, with OpenJDK 17 marking its latest evolution. If you’re looking to harness the capabilities of OpenJDK …
Let’s Encrypt is a Certificate Authority (CA) that facilitates obtaining and installing free TLS/SSL certificates, thereby enabling encrypted HTTPS on web servers. It simplifies the process by providing a software client, Certbot, that attempts to automate most (if not all) of the required steps. Currently, the entire process of obtaining and installing a certificate is fully automated on both Apache and Nginx. In this guide, we’ll use Certbot to obtain a free SSL certificate for Apache on Ubuntu 20.04, and make sure this certificate is set up to renew automatically. This tutorial uses a separate virtual host file instead of Apache’s default configuration file for setting up the website that will be secured by Let’s Encrypt. We recommend creating new Apache virtual host files for each domain hosted in a server, because it helps to avoid common mistakes and maintains the default configuration files as a fallback setup.
The Apache HTTP server is the most widely-used web server in the world. It provides many powerful features including dynamically loadable modules, robust media support, and extensive integration with other popular software. In this guide, we’ll explain how to install an Apache web server on your Ubuntu 20.04 server.
The LEMP software stack is a group of software that can be used to serve dynamic web pages and web applications written in PHP. This is an acronym that describes a Linux operating system, with an Nginx (pronounced like “Engine-X”) web server. The backend data is stored in the MySQL database and the dynamic processing is handled by PHP. This guide demonstrates how to install a LEMP stack on an Ubuntu 20.04 server. The Ubuntu operating system takes care of the first requirement. We will describe how to get the rest of the components up and running.
Nginx is one of the most popular web servers in the world and is responsible for hosting some of the largest and highest-traffic sites on the internet. It is a lightweight choice that can be used as either a web server or reverse proxy. In this guide, we’ll discuss how to install Nginx on your Ubuntu 20.04 server, adjust the firewall, manage the Nginx process, and set up server blocks for hosting more than one domain from a single server.

We recommend creating new Nginx server block files for each domain because it helps to avoid common mistakes and maintains the default files as a fallback configuration.
SSH, or secure shell, is an encrypted protocol used to administer and communicate with servers. When working with an Ubuntu server, chances are you will spend most of your time in a terminal session connected to your server through SSH. In this guide, we’ll focus on setting up SSH keys for an Ubuntu 20.04 installation. SSH keys provide a secure way of logging into your server and are recommended for all users.
When you first create a new Ubuntu 20.04 server, you should perform some important configuration steps as part of the initial setup. These steps will increase the security and usability of your server, and will give you a solid foundation for subsequent actions.
Apache Tomcat is a web server and servlet container that is used to serve Java applications. It’s an open source implementation of the Jakarta Servlet, Jakarta Server Pages, and other technologies of the Jakarta EE platform. In this tutorial, you’ll deploy Apache Tomcat 10 on Ubuntu 20.04. You will install Tomcat 10, set up users and roles, and navigate the admin user interface.
