  • Easy guide to monitoring your systems with Checkmk

    This tutorial will show you how to take your first steps with Checkmk, a comprehensive IT monitoring system that identifies issues across your entire IT infrastructure. Checkmk monitors servers, applications, networks, cloud environments and many other systems. I will show you how to install Checkmk on Ubuntu 20.04 and add hosts (systems to be monitored) to the monitoring. Checkmk also runs on other Linux distributions such as Debian, RHEL, CentOS or SLES, in a Docker container, or also as a virtual appliance. You can download the latest version for all platforms from the official Checkmk website. For this tutorial I will use the Checkmk Raw Edition, which is completely open source.

    The goal of this article is to give you a quick start into Checkmk and the world of IT monitoring. Checkmk comes with numerous powerful features, and I recommend checking the documentation online for further reference. You will see that it is fairly easy to set up a first monitoring, as many configuration tasks are performed automatically, and thanks to the around 2,000 official monitoring plug-ins, Checkmk supports many systems right out of the box.

  • Connect to an external PostgreSQL database with SSL and Red Hat's single sign-on technology | Red Hat Developer

The example connects to an external PostgreSQL database in secure Single Sockets Layer (SSL) mode, first locally and then on Red Hat OpenShift.

  • 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.
