  • MySQL Find Duplicate Values in Table – Linux Hint

    Redundant data can be kept in the table by the database program, influencing the database’s output in MySQL. Data replication, though, happens for different purposes, and it is an important job to identify the duplicate values in the table when dealing with a MySQL database. Broadly speaking, it is smart to use clear restrictions on a table often to store information that prevents redundant rows. Sometimes, in a MySQL database, you might like to calculate the number of repeated values. We addressed this question in this topic, in which you will learn about how to locate duplicate values through different ways and how to count duplicate values.

    To get started, you must have MySQL installed on your system with its utilities: MySQL workbench and command-line client shell. After that, you should have some data or values in your database tables as duplicates. Let’s explore this with some examples. First of all, open your command-line client shell from your desktop taskbar and type your MySQL password upon asked.

  • 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.
