  • How To Improve The Security Of Linux Servers?

    Many services nowadays run on servers with different Linux distributions. Compared to server versions of Microsoft operating systems, they are free. They are also generally considered to be more secure, but require deeper knowledge on the part of the system administrator to ensure they are configured correctly. It doesn't matter whether the system runs on your own infrastructure or on cloud solutions from Amazon, Microsoft or others. In this article, I'll give you tips for making your Linux instances more secure. The article also includes practical examples of improving the security of Debian-based operating system distributions.

    Automatic installation of updates

    Many servers become targets and victims of hacker attacks due to a security gap in the operating system used. Administrators are usually reluctant to update systems, as this can cause more harm than good, as deployed applications may stop working after a system update. However, it is extremely important for keeping the operating system secure and therefore automatic installations should always be enabled, especially on critical systems. If it is necessary to use older versions of operating systems, we recommend that these computers be completely isolated from the network. A few commands are all that is needed to enable automatic updates on a Linux system.

  • Learn essential Kubernetes commands with a new cheat sheet | Opensource.com

  • Resolve DHCPD and HTTPD startup failures with Ansible

    Last year, I had a problem: HTTPD (the Apache web server) would not start on a reboot or cold boot. To fix it, I added an override file, /etc/systemd/system/httpd.service.d/override.conf. It contained the following statements to delay HTTPD's startup until the network is properly started and online. (If you've read my previous articles, you'll know that I use NetworkManager and systemd, not the old SystemV network service and start scripts).

  • 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.

  • 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.
