How to Install Let’s Encrypt on CentOS 7 with Nginx

2 Comments

In this tutorial, we will set up a Let’s Encrypt SSL certificate on a CentOS 7 server with Nginx as the web server. After completing the instructions described in this article, you should be able to access your site using HTTPS.

Using SSL (short for Secure Socket Layer) is vital to keeping your site’s visitors safe as well as improving your webpage’s ranking on search engines. Without SSL, the data and information sent between your web server and your site’s visitors can be seen by third parties that are transmitting that data. With SSL, this data is encrypted, and only you and your visitors can see the information, keeping both sides safer.

Let’s Encrypt lets you set up an SSL certificate on your server for free. Their goal was to make SSL a commodity and give everyone the ability to have a safe and secure website. Let’s Encrypt makes the process of installing/renewing certificates easy for most users. This is very useful for making your website secure without needing the technical knowledge that is usually expected. Google and other search engines further encourage securing your website by giving websites that use SSL a higher ranking than websites without SSL.

In this guide, we will use the Certbot tool from EFF (https://certbot.eff.org).

How to Install and Configure TaskBoard on CentOS 7

Leave a comment

A need for “a simple, visual way to keep track of what needs to get done” is the main reason why the open-source TaskBoard has been developed. With a minimalistic design approach by the developer and contributors, TaskBoard aims to replicate the basics of commonly used Kanban apps like Trello and LeanKit all within a very small and light footprint.

Some of TaskBoard’s main key features are the following:

  • Email notifications
  • Unlimited and customizable boards with items
  • Full history logging
  • Robust privilege system
  • Supports file attachments

TaskBoard is licensed under the MIT License and can be self-hosted on a Linux-based server. For this tutorial, we recommend using a public-facing server with a freshly installed CentOS 7 Linux distribution, along with a registered domain name.

If you follow this guide on how to install and configure TaskBoard on CentOS 7 correctly, the install process won’t take more than 10-15 minutes. Let’s get started!

How to Set Up and Use Yum Repositories on CentOS 7

3 Comments

This tutorial explains how to set up and use Yum repositories on a CentOS 7 VPS.

The official CentOS 7 repository has a huge list of packages and it covers almost all bases in terms of software for servers, but sometimes we need some additional packages which are not available in the official repositories. In that case, we can simply add new repositories to further expand the catalogue of packages available to us. Let’s begin with the tutorial.

Run Java on CentOS with JRE

How to Run Java Files on CentOS with the JRE

2 Comments

There is a large amount of useful software for Linux packaged away in jar files, the main reason and benefit being that it allows for platform independence. For example, if you find a java utility that can minify, compress, and concatenate static files like JS and CSS for your website, you can download and use it on your own web server, regardless of the operating system.

But, you can’t run these jar files by default on any given Linux installation. A special interpreter needs to interpret the “bytecode” that they contain, and that is what the Java Runtime Environment (JRE) provides. Most Linux packages can be installed by using either the default repositories or by using the extended ones. (In the case of CentOS, these are the “EPEL” repositories.)

However, Java isn’t one of them. You need to download it from Oracle’s website and consent to a license agreement. In fact, this can be a bit of a problem as shown below.
