    The hostname is also known as a computer, device, or domain name that is given to a computer when it connects with the internet. The hostname has to be unique in the network and is assigned during the operating system installation. It may also assigned dynamically when a virtual machine is created.

    In CentOS 8, the hostnamectl and nmcli commands can be used to change the hostname of Desktop and Server systems. By using the hostname command, you can see the hostname of your system.

  • How To Create a Startup Script using Crontab in Lubuntu Linux

    Why do we need to create Startup Script to run after the operating system starts?

    If you have a home server, or maybe even just a Linux desktop, and you run the same fine-tuning commands each time you restart, running scripts automatically can make your life easier.

    The main reasons are that there will no longer be starting the server, logging in via SSH, entering a password, getting a root elevation and then manually executing script after script. Instead, we are going to use the power of Crontab and set your system to run these scripts automatically at startup! Here’s how to do it.

    There are two popular ways to check disk usage in Linux terminal: du command and df command. The du command is more for checking the space used by a directory and the df command gives you the disk utilization on filesystem level.

    There are more friendly ways to see the disk usage in Linux with graphical tools like GNOME Disks. If you are confined to the terminal, you can use a TUI tool like ncdu to get the disk usage information with a sort of graphical touch.

  • 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.

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.

  • 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.
