  • How to Create a Sudo User in CentOS - ByteXD

    The sudo command (originally standing for superuser do) is a program designed to allow a sysadmin to give certain users the ability to run some (or all) commands as root while logging the commands and arguments.

    With the sudo command, users can install, update, and remove packages and edit configuration files.

    This is very useful when you do not want to give a user a root password or if you want to allow a user to do something (i.e. su) without logging in as root.

    By default, the sudo command is disabled for standard users for security reasons to prevent any accidental overwriting of system files or any unauthorized root access.

    In this article, we will explain how to create a sudo user in CentOS by adding them to the wheel group.

  • Top Tips for Securing Your Linux System in 2021

    Linux servers are at greater risk than ever. While only a few years ago Linux users could count themselves as the “lucky few” who didn’t have to worry about malware and computer viruses, this era has unfortunately come to an end.

    Attackers now view Linux servers as a viable target that often provides a valuable return on investment. The past few years have been plagued with emerging Linux malware strains which have demonstrated new and dangerous tactics for spreading, remaining undetected and compromising servers - Cloud Snooper, EvilGnome, HiddenWasp, QNAPCrypt, GonnaCry, FBOT and Tycoon being among the most notorious examples.

  • 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.
