  • How To Install Apache Nifi on Ubuntu 20.04 LTS - idroot

    In this tutorial, we will show you how to install Apache Nifi on Ubuntu 20.04 LTS. For those of you who didn’t know, Apache NIFI is an open-source scalable tool to manage transformation, data routing, and system mediation logic. To put it in layman’s terms nifi simply automates the flow of data between two or more systems. Apache NiFi supports powerful and scalable directed graphs of data routing, transformation, and system mediation logic.

    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 through the step-by-step installation of the Apache Nifi on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.

  • How to best set up command aliases on Linux

    Used frequently, bash aliases can make working on the Linux command line a lot smoother and easier, but they can also be complicated and hard to remember. This post examines how you might make your aliases work for you rather than vice versa.

    [...]

    One of the nice things about aliases is that they remain available as you move around in your file system. They don't depend on your location or what's in your PATH variable. If you end up with 65 aliases, you might need to check them from time to time just to remember what they do. However, if you have to check very often, they might not be serving you as well as they should.

  • Static and dynamic IP address configurations for DHCP | Enable Sysadmin

    IP address configuration is one of the most critical, if simple, settings on your network devices. Workstations, servers, routers, and other components must have properly assigned IP address settings to participate on the network.

    This two-part article series covers static and dynamic IP address settings and the configuration of a DHCP server. This article (part one) defines network identities, contrasts static and dynamic configurations, and covers the commands needed to manage the settings. Part two covers the deployment of a DHCP server, DHCP scope configuration, and client-side management of dynamic IP addresses.

  • How to create Rocky Linux 8 bootable usb drive - Linux Shout

  • How to configure Noscript for ordinary users

    The Noscript Security Suite (NSS) is a fantastic, fantastic tool. It comes as an extension for Firefox and various Chromium-based browsers, and what it does is transform the useless, noisy so-called "modern" Internet into a pool of tranquility. And it does so by blocking scripts and other elements on Web pages. Beautiful, elegant. You end up with a fast, quiet experience. No nagging, no overhead. When you do need scripting, you selectively enable it. Works great, but only if you're a techie.

    Unfortunately, for common folks AKA not nerds, this is not a solution. They can't be bothered with per-site permissions, figuring out if something is broken when scripts don't run, or similar. But then, what if you do want to have all the flexibility of non-restricted browsing but still use some of the great powers of Noscript? Well, I think I may have the formula. Follow me.

  • How to accurately match OVAL security data to installed RPMs

    Red Hat publishes security data using the Open Vulnerability and Assessment Language (OVAL). Depending on what you have installed, according to the Red Hat and OVAL compatibility FAQ, you'll need to scan streams for all products installed on your system. This post aims to answer the question of how to determine which stream to use when scanning a system. We’ll use an operating system and container image as target systems to explore the topic.

    On April 27, 2020 Red Hat started publishing repository-to-CPE mapping data (JSON file) to make this task easier. Then in December 2020 we added support for Red Hat Enterprise Linux update streams such as Extended Update Support (EUS).

  • 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.
