  • How to install Node.js on Fedora 35 – NextGenTips

    In today’s guide, I am going to take you through the installation of node.js on Fedora 35.

    Node.js is an open-source cross-platform, backend javascript runtime environment that runs on the V8 engine and executes javascript code outside of a web browser.

    A Node.js app runs in a single process, without creating a new thread for every request. It provides a set of asynchronous I/O primitives in its standard library that prevent javascript code from blocking and generally, libraries from node.js are written using non-blocking paradigms, making blocking behaviour the exceptions rather than the norm.

    When Node.js performs an I/O operation, like reading from the network, accessing a database or the filesystem, instead of blocking the thread and wasting CPU cycles waiting, Node.js will resume the operations when the response comes back. This allows Node.js to handle thousands of concurrent connections with a single server without introducing the burden of managing thread concurrency, which could be a significant source of bugs.

  • How to Make iptables Firewall Rules Persistent on Debian/Ubuntu

    Here’s how to keep iptables firewall rules persistent between reboots, so you don’t lost them after the system is rebooted.

    Iptables is a command-line firewall utility in Linux operating system that uses policy chains to allow or block traffic. However, by default iptables rules will not survive through a server reboot. They are reset when you reboot your Linux system. So, how do I persist iptables rules?

    The iptables store the rules in the system memory. In other words, it do not save these rules persistently to the disk as a file. Fortunately, there is a very easy way to keep these iptables rules persistently to a disk, which I will show you now.

  • How to Install Telegraf Configure InfluxDB2 output in Rocky Linux/CentOS 8

    In this guide we are going to learn how to install Telegraf and configure InfluxDB v2 output on a Rocky Linux server 8. This guide also works for any RHEL 8 based server like Alma Linux 8, Centos 8, Oracle Linux 8 etc.

Telegraf has plugins to source a variety of metrics directly from the system it’s running on, pull metrics from third-party APIs, or even listen for metrics via a statsd and Kafka consumer services. It also has output plugins to send metrics to a variety of other datastores, services, and message queues, including InfluxDB, Graphite, OpenTSDB, Datadog, Librato, Kafka, MQTT, NSQ, and many others.

  • How To Install System Information Tool HardInfo 0.6 Alpha (GTK3) On Ubuntu, Pop!_OS Or Linux Mint From PPA - Linux Uprising Blog

    HardInfo is a graphical system information (hardware, system info, software) and benchmark tool. Since there have not been any new HardInfo releases since 2009 (but the tool is still under development), I have created a PPA to easily install HardInfo 0.6 alpha (from Git) built with GTK3 on Ubuntu, Pop!_OS and Linux Mint. At the end of the post, you'll also find links with newer, third-party HardInfo packages for Arch Linux and Fedora.

    Hardinfo system hardware information Linux
    The application can display system hardware information such as CPU (cores, frequencies, cache, etc.), RAM (available RAM, memory sockets, etc.), motherboard and BIOS, GPU, disks, peripherals, temperatures and much more.

    What's more, the tool can also show software information like the used Linux distribution and version, kernel information and loaded modules, installed development tools versions, as well as system information like boot history, memory usage, filesystem usage, display (e.g. the screen resolution, the session type: X11 or Wayland, etc.), and more.

  • How To Install MariaDB on Fedora 35 - idroot

    In this tutorial, we will show you how to install MariaDB on Fedora 35. For those of you who didn’t know, MariaDB is an open-source one of the most popular relational database management systems (RDBMS) that is a highly compatible drop-in replacement of MySQL. It offers a better storage engine along with faster caching and query performance.

    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 through the step-by-step installation of the MariaDB 10.6 on a Fedora 35.

  • 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.
