301 Redirect HTTP to HTTPS in NGINX: Quick Tutorial

by

If your website is hosted with NGINX and it has SSL enabled, it’s best practice to disable HTTP completely and force all incoming traffic over to the HTTPS version of the website. This guide will show you how to configure a 301 redirect HTTP to HTTPS to avoid duplicate content and ensure that all of the site’s users are only browsing the secure version of your website. In this guide, we’ll assume you’re already using NGINX on a Linux system and want to implement an nginx redirect HTTP to HTTPS. Even if a user happens to follow an http:// link, the site should send them to the correct and secured page, which happens instantly and without the user’s intervention.

There are two ways to setup this redirection in NGINX. One method allows you to configure the redirection for individual sites. The other method can redirect HTTP to HTTPS for all NGINX sites on your server, which is handy if you have multiple sites setup and want to avoid having to apply the exact same redirection to each one. We’ll cover the step by step instructions for both methods below. Let’s get started.

NOTE
Using Apache instead of NGINX? We’ve written a separate guide for how to use Apache to redirect all HTTP traffic to HTTPS.

In this tutorial you will learn:

  • How to redirect HTTP to HTTPS for individual NGINX websites
  • How to redirect HTTP to HTTPS for all NGINX websites

Exploring the Foundations of Linux: A Look at Major Distributions and Their Base Systems

Major Linux Distributions and Their Base Systems: Understanding the Foundation

by

In the world of operating systems, Linux stands out not only as a robust and versatile platform but also as a vibrant ecosystem with hundreds of unique distributions (often referred to as distros). Unlike proprietary systems, Linux is open-source and community-driven, meaning anyone can modify, improve, or create their own variant. This has led to a vast and dynamic landscape of Linux distributions, each with its own focus, strengths, and intended audience. From high-performance server environments to user-friendly desktop options, and even lightweight operating systems for aging hardware, Linux distributions cover almost every conceivable use case.

Apache, MySQL, and Python can be used in tandem to host and serve a website from a Linux system. This assortment of software is known as a LAMP stack (Linux, Apache, MySQL, Python) although sometimes the ‘P’ means PHP, which can either be used in addition to or as a replacement of Python.

Raspberry Pi as Minecraft Server

Raspberry Pi as Minecraft Server

by

A Raspberry Pi, especially the newer models, possesses all the necessary hardware power for running a dedicated Minecraft gaming server. While it is easy enough to host the game off your desktop computer while simultaneously playing, having a dedicated server allows you to host an uninterrupted Minecraft session that can stay up and running for longer periods of time. Rather than buying a robust rig to host your server, or paying a third party company to do the hosting for you, utilizing the Raspberry Pi becomes a cheap alternative.
