  • How to Install Java 16 (OpenJDK 16) on Rocky Linux 8

    Java is a general-purpose, class-based, object-oriented multipurpose programming language that is popular due to the design of having lesser implementation dependencies, meaning that the compiled Java code can be run on all platforms that support Java without the need for recompilation. Java is also fast, secure, and reliable, therefore. It is widely used for developing Java applications in laptops, data centers, game consoles, scientific supercomputers, cell phones, etc.

  • 2 Ways to install Webmin on Rocky Linux 8 Server - Linux Shout

    Webmin is a web-based tool meant to install on a Linux server to manage it using a graphical user interface. It is open source and can be installed on popular Linux distros using few commands.

  • How to Download Files from Remote Linux Servers

  • How to Delete Empty Lines in Files Using Grep, Sed, and Awk

    An experienced Linux user knows exactly what kind of a nuisance blank lines can be in a processable file. These empty/blank lines not only get in the way of correctly processing such files but also make it difficult for a running program to read and write the file.

    On a Linux operating system environment, it is possible to implement several text manipulation expressions to get rid of these empty/blank lines from a file. In this article, empty/blank lines refer to the whitespace characters.

  • Install Linux with LVM |

    A couple of weeks ago, the good folks at Linux Mint released version 20.2 of their open source operating system. The installer built into the live ISO is excellent and only requires a few clicks to install the OS. You even have a built-in partitioner if you want to customize your partitions.

    The installer is mainly focused on a simple install—define your partitions and install into them. For those wanting a more flexible setup—logical volume manager (LVM) is the way to go—you benefit from setting up volume groups and define your logical volumes within them.

    LVM is a hard drive management system that allows you to create storage space across multiple physical drives. In other words, you could "tether" a few small drives together so your OS treats them as if they were one drive. Beyond that, it has the advantages of live resizing, file system snapshots, and much more. This article isn't a tutorial on LVM (the web is full of good information on that already.) Instead, I aim to keep this page on topic and focus solely on getting Linux Mint 20.2 working with LVM.

  • JQ Command in Linux with Examples – TecAdmin

    JSON is a data representation format that is used to store and transfer data between different layers of an application; it stores data in key: value pairs.

    The syntax of JSON was derived from JavaScript but it itself is language independent. It is compatible with many programming languages; these languages include code that can be used to integrate JSON into the program; but unfortunately, we cannot work with JSON directly in Linux shell as it cannot interpret it. To work with JSON in the Linux shell we use a mixture of tools such as JQ and sed.

    In this post, we will learn to use the JQ command to manipulate and work with JSON data in a Linux shell.

  • Fix Linux mint 20 - Cannot add PPA: ''This PPA does not support focal''.

    If you are adding PPA repo in Linux mint 20.02 and getting an error Cannot add PPA: ”This PPA does not support focal”. Then follow the simple command given in the article that will solve this error.

    PPA stands for “Personal Package Archive” offered by developers and package maintainers on a service called Launchpad. The developers can upload Debian source packages into a PPA that is used by Launchpad automatically to build binary packages for different architectures and Ubuntu versions that can be used on Linux Mint as well.

    It helps beginners to installing various programs in an easy way without compiling them manually from the source code that is not included in the official package sources or only in an older version.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • 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.
