  • How to run a single command on multiple Linux machines at once | TechRepublic

    Of course, there are apps for that. But since this is Linux, wouldn’t it make more sense to piece together your own solution? Of course, it would. After all, Linux is about choice, power and flexibility.

    Say, for example, you had several Ubuntu Servers and you wanted to run sudo apt-get update and sudo apt-get upgrade on them all at once. You don’t have to log in to each of those machines to run those commands, not when there are scripts to handle that task for you.

    I’ve found such a script and have modified it in a way that you can use it to create multiple scripts for specific hosts (such as Ubuntu- or RHEL-based servers). Let’s take a look at this script and see how to make it work.

  • How To Install TeXstudio on Ubuntu 20.04 LTS - idroot

Some of the outstanding features of TeXstudio are an integrated pdf viewer with (almost) word-level synchronization, advanced syntax-highlighting, live checking of references, latex commands, spelling, and grammar.

    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 TeXstudio editor 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 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.

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.

  • 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.
