  • How to Generate Self-Signed SSL Certificates using OpenSSL

    Ideally, SSL certificates are issued by publicly trusted certificate authorities (e.g. Let’s Encrypt, Comodo, Verisign) to provide authentication and encryption on the internet. However, you could obtain an SSL certificate without going through a third-party certificate authority — this is what is referred to as a self-signed certificate.

    This tutorial describes how to generate a self-signed SSL certificate by using OpenSSL in Linux. OpenSSL is an open-source software library used to implement secure communications on the Internet.

  • How To Install RavenDB on Ubuntu 20.04 LTS - idroot

    In this tutorial, we will show you how to install RavenDB on Ubuntu 20.04 LTS. For those of you who didn’t know, RavenDB is a NoSQL database manager written in C#. With a RavenDB database, you can set up a NoSQL data architecture or add a NoSQL layer to your current relational database. RavenDB supports multiple databases, sharding, or partitioning the data across multiple servers. It has the ability to handle hundreds or thousands of databases on the same instance. RavenDB uses JSON to store documents and does not requires a schema to be declared and enables developers to work with data more naturally.

    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 RavenDB on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.

  • APT Command in Linux – A Definitive Guide

    APT also know as the “Advanced Package Tool” is a package management tool for Debian-based distributions including, Ubuntu, Debian and Linux Mint.

  • Creating a backup of data stored in a Linux virtual machine

    In this article, I cover what I've learned about backing up data stored in a Red Hat Enterprise Linux (RHEL) virtual machine (VM). During my first year of working with Linux, I had the idea of backing up data on a Linux VM deployed in the cloud.

    Backing up data is a major business issue. With an increasing number of cyber threats, user errors, and system failures, your data is not safe. Backing up data prevents the loss of important files and folders when there is a security breach, accidental deletion, or in the event of a system failure. Individuals and small-to-medium-sized businesses can backup data to external hard discs, or to backup servers, but for large enterprises where the amount of data is huge (Petabyte scale), data backup is complex and is often done, at least partially, on some form of cloud architecture.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. 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 the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • 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.
