Ubuntu Polishes GNU Screen

Filed under
Software

GNU Screen is a terminal multiplexer program that Linux folk have used for ages. It allows you to turn one terminal into many, and run processes even after logging out. In this article we will give a brief overview of screen usage for the uninitiated, then talk about how Ubuntu’s defaults and new screen-profiles package have taught us about new and wonderful features of screen.

Screen is wonderful for work management. You can have a standard layout of screen windows, each one dedicated to a different server. You will instinctively press C-a 8, for example, when you think about the ssh session that generally lives in that window.

Most often, we will want to do something else while waiting for a long-running command to finish. Easy enough: Just create a new window and carry on. This is also very handy for “leaving.” If you ssh to a server from your laptop and start a process or script that takes an extremely long time to complete, you may be stuck.

  • 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.
