  • How To Fix “502 Bad Gateway” Error In Nginx

    The 502 Bad Gateway error is an HTTP status code that means that one server received an invalid response from another server. In more technical words, A 502 Bad Gateway means that the proxy (gateway) server wasn’t able to get a valid or any response from the upstream server.

    If you are seeing a 502 bad gateway error on a website, it means that the origin server sent out an invalid response to another server that acted as a gateway or proxy. It can be a tricky investigation to locate what and where is the process which caused the issue. However, there are some general troubleshooting steps that you can follow to get it solved.

    For example, if you use Nginx as the webserver and you encounter this issue, it could be that Nginx is unable to communicate with the upstream server, this upstream server could be PHP-FPM or other application that you want to access through Nginx, like Odoo, NodeJS, etc.

  • How to Access Extra Dock Settings in elementary OS 6 - OMG! Ubuntu!

    Today I learnt how to access more Plank dock setting in elementary OS 6, and figured I’d pass the knowledge on.

    A clutch of dock config options can be accessed in elementary OS right from the System Settings > Desktop > Dock & Panel panel. This includes options to change dock icon size, auto-hiding behaviour, and enable pressure reveal.

    But you can access even more dock settings in the distro without needing to install anything extra.

    Ass you probably know the dock app used in elementary OS is Plank. On other distros it is easy to access Plank’s broad array of settings: right-click on the Plank icon (or an empty part of the dock), choose ‘Preferences‘ and away you go.

  • 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.
