  • How To Install OpenSSL on CentOS 8 - idroot

    In this tutorial, we will show you how to install OpenSSL on CentOS 8. For those of you who didn’t know, OpenSSL is a robust, commercial-grade, full-featured Open Source Toolkit for the Transport Layer Security (TLS) protocol formerly known as the Secure Sockets Layer (SSL) protocol. The protocol implementation is based on a full-strength general-purpose cryptographic library, which can also be used stand-alone. OpenSSL is used by many programs like Apache Web server, PHP, and many others providing support for various cryptographic algorithms such as ciphers (AES, Blowfish, DES, IDEA, etc.), and cryptographic hash functions (MD5, MD4, SHA-1, SHA-2, etc.)

    This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step-by-step installation of the OpenSSL on a CentOS 8.

  • Chattr Command in Linux with Examples – TecAdmin

    The “chattr”, short for change attribute, is a command-line utility in Linux used to change attributes of a file e.g a, i. This command is primarily used to make various files immutable and undeletable for regular users.

    File management is a complicated process in Linux as it is a multi-user operating system. The administrators can change the attributes of a file using the “chattr” command so it cannot be accessed and changed by anyone except the superuser. This saves the important files from accidental deletion.

    In this write-up, we will focus on how to modify the attributes of a file by using the “chattr” command. We will also learn about different flags that can be used along with the “chattr” command.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
