  • How to Install Glances System Monitor on Ubuntu 22.04 LTS

    Glances System Monitor is free, an open-source command-line tool for process monitoring, system resources such as CPU, Disk I/O, File System, Load Average, Memory, Network Interfaces, and processes. Glances are built with Python language. Glances support cross-platform monitoring, which can be used with a web-based interface.

    One of the excellent features Glances supports is setting thresholds in the program. You can set careful, warning, and critical in the configuration file, which will then relay information in colors that can show alerts to systems resources bottlenecks, system resources issues, and much more. Glances, by default, comes with a pre-set list of colors, but you can modify and add additional configs.

    The following tutorial will demonstrate how to install or enable and configure Glances System Monitor on Ubuntu 22.04 LTS Jammy Jellyfish Desktop or Server using the command line terminal.

  • Enable & Configure Gzip Compression on Nginx

    Part of any website operation is to make sure visitors can view the site as quickly as possible. Still, one of the biggest causes of slowdowns is loading resources that depend on size can severely impact a website without GZIP enabled to a similar website.

    NGINX is an excellent web server, built for speed, lightweight to handle multiple connections, and it does come with GZIP support, but this can be a double-edged sword as using GZIP increases CPU utilization. Depending on your server and its resources, it could have the opposite impact enabling it without optimization.

    So interested in the topic so far? In our tutorial, you will learn the basic GZIP setup and configuration on Nginx, which can be used on any operating system, UNIX or Windows.

  • linuxium.com.au: Customizing Ubuntu ISOs: Documentation and examples of how to use 'isorespinner.sh'

    This script is a ​progression of 'isorespin.sh'. Whilst 'isorespin' was created to support Ubuntu and similar Linux distributions on mini PCs, some of the functionality that was developed is now unused. Additionally with ​Canonical now trialling a new ​Ubuntu ​desktop installer and the ISO using a new multi-layer filesystem, rather than hack the ​earlier code to coerce compatibility I'​ve​ developed a new script ​which I've called ​'isorespinner.sh' ​which provides the most useful features and ​addresses the functionality that is ​now relevant to​ ​respinning.

  • 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.
