  • How To Create a Large 1GB or 10GB File in Linux System

    Since Linux has been used widely for all data communication, networking, and data analysis, the demand for generating live data, static data, and dynamic data is also high.

  • How To Install Discourse on Ubuntu 20.04 LTS - idroot

    In this tutorial, we will show you how to install Discourse on Ubuntu 20.04 LTS. For those of you who didn’t know, Discourse is an open-source platform used for discussions forum, chat rooms, or as a mailing list management software. It is a modern forum solution that powers discussions on thousands of sites to drive user engagement. A discourse was written in Ruby on Rails as a backend language, Ember.js as a frontend, and uses PostgreSQL for data storage.

    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 Discourse on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.

  • How to install Node.js 17 on Ubuntu 20.04 – NextGenTips

    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 behavior 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.

    nvm is used to run node.js packages. It allows you to easily switch node.js versions and install new versions to try and easily roll back if something went wrong.

  • 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.
