  • How to install Telnet on CentOS 9 Stream

    Hello, friends. In this post, you will learn how to install Telnet on CentOS 9 Stream. It may not be of much practical use today, but it is always important to do it for educational and testing purposes.

    Telnet is the name of a network protocol that allows us to access another machine to manage it remotely as if we were sitting in front of it. It is a rather old protocol and few uses it nowadays, but it can be interesting for other purposes.

  • How to Install Htop to Monitor Alpine Linux

    The top command is a handy command-line tool that displays running processes on a Linux system in real-time. It provides a summary of all the processes being handled by the Linux kernel and some vital system metrics such as uptime, load average, and resource usage (CPU & memory usage).

    Htop is an improved implementation of the top command, which is a text-mode interactive process viewer that provides real-time interactive monitoring of processes and metrics in a colorized output. It is more intuitive and provides a much more appealing look at the running processes and metrics.

  • How to Make a User an Administrator in Debian 11 - VITUX

    If you have multiple user accounts in your system, it is not a good idea to give administrative privileges to all of them. It is always safe to limit the privileges of certain accounts to prevent unauthorized and potentially harmful changes to the system.

    However, if you want to assign administrative privileges to certain users, you can do it using various methods. In this article, we will discuss the methods you can use to make a user an administrator in your Debian operating system. This includes both the GUI and the command line. When you make a user an administrator, they are given all administrative privileges, such as installing and uninstalling software, making changes to system settings and configurations, etc.

    We used Debian 11 and Debian 10 to successfully test the commands and procedures mentioned in this article.

  • SQLite SELECT DISTINCT Statement

    SQLite is a framework that defines a transaction-oriented SQL database system that is self-contained and requires no deployment. SQLite’s codebase is in the mainstream, which means it could be used for every intent, personal or professional. SQLite is perhaps the most extensively used database worldwide, including an uncountable number of applications and some elevated initiatives.

    SQLite is a SQL database system for integrated devices. SQLite will not include a discrete server component like many other Database systems. SQLite writes data to regular database files natively. A single database file consists of a whole SQL database, including many tables, indexes, initiates, and columns. We can easily replicate a database across 32-bit and 64-bit operating systems because the file type of the database file type is multidimensional. SQLite is a widely used statistical File System because of these attributes.

    The “DISTINCT” term in SQLite can evaluate the “SELECT” command’s dataset and remove all duplicate values, ensuring that the retrieved entries are from a valid set of the “SELECT” query. When deciding whether or not a record is a duplicate, the SQLite “DISTINCT” term analyzes just one column and data provided in the “SELECT” command. In the SQLite “SELECT” query, when we declare “DISTINCT” for a single column, the “DISTINCT” query would only retrieve unique results from that defined column. When we can apply a “DISTINCT” query for more than one column in the SQLite “SELECT” command, “DISTINCT” can assess duplicate data using a combination of each of these columns. NULL variables are taken as redundancies in SQLite. Thus, if we are using the “DISTINCT” query on a column with NULL entries, this will only retain a single row containing NULL data.

  • 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.
