  • How to back up MySQL databases from the command line in Linux | FOSS Linux

    The current technological evolution of every aspect of life has made data more precious than gold and silver. If you can acquire, grow, and protect data, you are one step away from being a data god. Yet, big companies that control life aspects like e-commerce, fuel, transport, and food landscapes rely on data protection to shield themselves from an inevitable collapse.

    Right now, losing data is like losing your life insurance. So the database management system you are using should have a backup orientation. If you are a MySQL administrator or a user dealing with growing data, you should consider implementing a more than frequent backup automation plan. Reason? You might end up being a victim of a data hack or even alter your data by accident.

    Such circumstances can lead to unforgiving data breaches, especially when you don’t have a database backup plan. If you are an invested MySQL user or administrator, this article is here to fix your database backup worries. We will meet two objectives. First, you will understand the implementation of exporting databases through “mysqldump”. Then, finally, we will touch on how using “crontab” can make this entire process easier through automation.

  • How To Enable Full Disk Encryption on an Ubuntu 20.04 Desktop - JumpCloud

    Device security is one of the primary concerns that security professionals, developers, and other IT professionals have in the face of a growing number of cyber threats. Criminal hackers are increasingly more sophisticated in their attack vectors and constantly inventing new ways of bypassing even the most secure systems. Though some may argue that Linux is the most secure and stable operating system, it can still fall prey to the same misconfigurations and user errors that plague users of Mac and Windows devices.

    No device is foolproof, and like many things in your environment, your Linux system is as secure as its weakest point. The default configurations chosen during the first installation are not enough to harden your device, and unpatched Linux systems and the use of outdated software can significantly increase the chances of a breach. In a worst-case scenario you may find your hard drive completely wiped, with critical files inaccessible and possibly stolen without much evidence left behind. Source code stored on a Linux laptop could fall prey to malicious individuals or perhaps there is PII stored on the laptop in a local file or database; regardless of the individual use case, ensuring that your data is secure is critical.

    There are various steps you can take to safeguard Linux devices from potential breaches. One of them is enabling full disk encryption on their drive.

  • 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.

  • 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.
