Major Linux Distributions and Their Base Systems: Understanding the Foundation
In the world of operating systems, Linux stands out not only as a robust and versatile platform but also as a vibrant ecosystem with hundreds of unique distributions (often referred to as distros). Unlike proprietary systems, Linux is open-source and community-driven, meaning anyone can modify, improve, or create their own variant. This has led to a vast and dynamic landscape of Linux distributions, each with its own focus, strengths, and intended audience. From high-performance server environments to user-friendly desktop options, and even lightweight operating systems for aging hardware, Linux distributions cover almost every conceivable use case.
Check Debian Linux version
Being aware of your current Debian version will help you know when it is time to update. It’s important to know the version of your Debian Linux system, as new versions are released about every 2 years. Just like checking any linux version, staying up to date will keep your system secure and ensure that you have the newest software available.

What is ELK
If you’re in a situation where you manage large amonts of data logs, the ELK stack is exactly what you’re looking for. The ELK stack combines Elasticsearch, Logstash, and Kibana into a simple, yet powerful, open source stack that lets you manage large amounts of logged data from a convenient graphical web interface.
All three tools are developed by Elastic, so they work in tandem perfectly, and they’re very easy to get set up on your Ubuntu system.
How to Manage Kubernetes Clusters With kubectl
The kubectl command is how administrators interact with and manage a Kubernetes cluster on a Linux system. It is an essential command line tool that works with all Kubernetes cluster envrionments like Amazon Web Services, Google Cloud Platform, or a cluster on your own hardware (e.g., kubeadm). Managing Kubernetes clusters at scale can be a challenge at first, but mastering the kubectl command will make it much easier.
Install ssh server on CentOS 8 / RHEL 8
The SSH server might already be installed on your RHEL 8 / CentOS 8 system. If you need to install ssh, you can check the status of your SSH server using the systemctl status sshd command. We will then install the openssh-server package below by using the dnf command.
In this tutorial you will learn:
- How to install SSH server onRHEL 8 / CentOS 8.
- How to open SSH firewall port 22 on RHEL 8 / CentOS 8.
- How to enable SSH to start after reboot on RHEL 8 / CentOS 8.
How to install RealVNC viewer on Linux
RealVNC is a commercial VNC solution for various types of operating systems, including Linux. It allows users to control a computer remotely, and interact with the desktop as if they were sitting directly in front of the remote computer. The remote computer should be running RealVNC Server, while the client must run RealVNC Viewer in order to connect to the server and control the computer.
What is DHCP and how to configure DHCP server in Linux
DHCP is a networking protocol used to assign IP addresses to networked devices. In this guide, we’ll introduce you to the protocol and explain how it works. You’ll also see how to implement a DHCP server on Linux systems, and configure it for your own network.
In this tutorial you will learn:
- What is DHCP?
- How to implement a DHCP server on major linux distros
- How to configure DHCP on Linux
How to setup Linux Apache Mysql Python server
Apache, MySQL, and Python can be used in tandem to host and serve a website from a Linux system. This assortment of software is known as a LAMP stack (Linux, Apache, MySQL, Python) although sometimes the ‘P’ means PHP, which can either be used in addition to or as a replacement of Python. Apache serves the website, MySQL stores and retrieves information from a database, and Python can generate HTML and related code for the site’s visitors to view.
Raspberry Pi as Minecraft Server
A Raspberry Pi, especially the newer models, possesses all the necessary hardware power for running a dedicated Minecraft gaming server. While it is easy enough to host the game off your desktop computer while simultaneously playing, having a dedicated server allows you to host an uninterrupted Minecraft session that can stay up and running for longer periods of time. Rather than buying a robust rig to host your server, or paying a third party company to do the hosting for you, utilizing the Raspberry Pi becomes a cheap alternative. On top of that, you still have the ability to customize the server configuration to produce your ideal gaming environment.
sudo command not found – Solution
If you have tried to run the sudo command on your Linux system and are greeted with a sudo command not found error, we have the solution for you. This error most commonly occurs on minimal installs, such as in Docker or on a VPS (virtual private server), and can happen on any Linux distro, like Ubuntu Linux and Debian . In this tutorial, we will show you how to resolve the error and give you the ability to run sudo commands without error.
How to install ActiveMQ on RHEL 8
Apache ActiveMQ is a widely used messaging server written in Java. As messaging services commonly do, it creates a bridge between heterogeneous systems for reliable data exchange in the form of messages pushed into queues by producer clients, where they wait to be “read”, or consumed by consumer clients.
Naturally a system that is client to ActiveMQ can be both producer and consumer, and more than one systems can subscribe to a queue or topic, thus enabling flexible communication between these client systems. Many different platforms and protocols can be used to connect to ActiveMQ, increasing it’s usefulness even more.
In this tutorial we will install Apache ActiveMQ on Red Hat Enterprise Linux 8 from tarball, add the systemd unit files for ease of use, and access the admin page of our new service to create a queue.
In this tutorial you will learn:
- How to install ActiveMQ from tarball
- How to set up environment from the command line
- How to add systemd unit files for ActiveMQ
- How to access the admin page
