  • Linux 101: How to easily view real-time log entries with tail - TechRepublic

    One of the single most helpful tools in your Linux admin arsenal is log files. And with the open-source platform, there are quite a few different log files to view. But how do you get the most out of your viewing?

    One of the best ways to use log files to troubleshoot a system is by viewing the log in real-time. As the logging system writes entries to the log file, it makes it considerably easier to see what's going on in such a way as to help discern what's causing the problem.

    The other option is to open the log file and either scroll through it or search it for specific strings. Personally, I much prefer the real-time option.

    To view a log file in such a way, there's a handy command available, called tail. According to the tail man page, tail will print the last 10 lines of each file to standard output. In simplest terms, tail prints out the most recent entries to a file as they are written.

  • How to Export MySQL Query Results to CSV Format in Linux

    Querying from a MySQL database shell is always fun and techy until you need a database output saved somewhere for easy access and reference; especially when dealing with large datasets.

    Quick data access saves you from having to each time log in to a MySQL server via a terminal shell to reference specific MySQL-query-associated outputs. The CSV (Comma Separated Value) file is an ideal candidate for resolving these types of repetitive user-to-database interactions.

  • How to Self-host Multiple WordPress Sites on the Same Server With Docker

    Installing WordPress is not a big deal. You can install it using LAMP server for local development. You can also deploy it for the real world on a proper public facing Linux server.

    Cloud servers like Linode, DigitalOcean etc also provide the option to deploy a brand-new Linux server preconfigured with WordPress. Even easier, right?

    But what if you want to install more than one WordPress on a single server?

    An easy way would be to use a service like ServerPilot. Not only it updates your server automatically, it also lets you easily deploy multiple WordPress instances on the same server.

    That would cost you a bit more money and if you do not want that, you can use Docker to deploy multiple WordPress instances.

    Through this guide, you'll learn how to easily set up a dual WordPress setup running from their individual containers and add more instances!

  • 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.
