  • How to Reset Root Password in Rocky Linux or AlmaLinux | Mark Ai Code

    It does happen. Yes, it is possible to lose track of your passwords, including the root password, which is required to conduct root-privileged actions. This can happen for a variety of reasons, including not signing in as a root user for an extended length of time or having a complicated root password – in which case you should consider using a password manager to properly store your password.

    Don’t worry if you’ve forgotten your root password and have nowhere to go for it. If you have physical access to your server, you may easily reset your lost root password.

    Follow along as we demonstrate how to reset a lost root password in Rocky Linux / AlmaLinux.

  • Using sed for Find and Replace

    You need the ability to search and manipulate text on the command line, especially when performing repetitive tasks. This is what makes sed, or stream editor, so valuable. sed is a Unix text processing and manipulation CLI tool. A stream editor takes in text from an input stream and transforms it into a specified output according to instructions. The input stream could be from pipelines or files.

    sed reads input text from files or stdin, then edits the text line by line according to the provided conditions and commands. After sed performs the specified operation on each line, it outputs the processed text to stdout or a file, then moves on to the next line.

  • 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.
