• How to Install LAMP stack on Ubuntu 22.04 - RoseHosting

  The LAMP is a shortcut to Linux, Apache, MySQL, and PHP. The Linux operating system in this tutorial will be the latest Ubuntu 22.04. Apache is an HTTP web server used to serve the requests, MySQL is a relational database management system used for storing data, and PHP is the website’s language. The LAMP stack is used for creating websites and web applications. We are going to explain in more detail how these four software are connected to each other.

• How to use Block Storage to Increase Space on Your Nextcloud Instance | Linux Journal

  In a previous article, I showed you how to build your very own Nextcloud server. In this article, we're going to extend the storage for our Nextcloud instance by utilizing block storage. To follow along, you'll either need your own Nextcloud server to extend, or perhaps you can add block storage to a different type of server you may control, which would mean you'd need to update the paths accordingly as we go along. Block storage is incredibly useful, so we'll definitely want to take advantage of this.

• How To Install Remmina on Ubuntu 22.04 LTS - idroot

  In this tutorial, we will show you how to install Remmina on Ubuntu 22.04 LTS. For those of you who didn’t know, Remmina is a remote desktop client written in GTK+, aiming to be useful for system administrators and travelers, who need to work with lots of remote computers in front of either large monitors or tiny netbooks. Remmina works on multiple protocols like RDP, VNC, NX, XDMCP, SPICE, HTTP/HTTPS, SSH, and SFTP protocols.

  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 Remmina remote desktop on Ubuntu 22.04 (Jammy Jellyfish). You can follow the same instructions for Ubuntu 22.04 and any other Debian-based distribution like Linux Mint, Elementary OS, Pop!_OS, and more as well.

• Limine Installer enhanced EFI chainload

  The previously-installed mainstream Linux distributions had installed GRUB2, so I have enhanced Limine Installer to detect this and chainload to it. In the earlier test, these were the detected installations...

• The brains behind the books: Jana Jaeger | SUSE Communities

  After a brief stint at Tanner AG where I met my friend and then and now colleague, Tanja Roth, I rejoined SUSE to spend the next 8 years writing for SUSE Linux Enterprise Server for IBM zSeries, and for what later became SUSE Linux Enterprise Desktop. The next years were fantastic—writing and fighting alongside as part of the best team of writers in the world ;).

Update #2

• How To Automatically Update Running Docker Containers Using Watchtower

  Keeping the Docker containers up-to-date is one of the important job of a DevOps engineer. Manually updating Docker containers is a quite time consuming task. This guide explains what is Watchtower, how to install Watchtower, and how to automatically update running Docker containers using Watchtower in Linux.

• How to sync time on Linux servers with Chrony

  Recently, I ran into an issue where I discovered a few Linux servers I work with were operating under an assumed time zone. Because of that time drift, certain services wouldn’t function properly. In particular, two servers both served as nodes on a Docker Swarm cluster and were unable to perform their duties and MariaDB database replication failed. After fixing that simple issue, I realized it was time to start paying closer attention to the time on my servers.

  With that, I was reminded of a tool that helps make this simple. Said tool is Chrony, which will constantly keep your time in sync on your servers and desktops.

Update

• ZFS pool IO statistics (and vdev statistics) are based on physical disk IO

  Today I wound up re-learning something that I sort of already knew about the IO statistics about pools and vdevs that you can get through things such as zpool iostat. Namely, that at least for bytes read and written and the number of IO operations, these IO statistics are what I call physical IO statistics; they aggregate and sum up the underlying physical disk IO information.

• Revisiting the Web Analytics Rabbit Hole

  A little over a year ago, I removed all analytics from this site because it was sending me down a rabbit hole that I didn’t like. Here’s an update.

• Re: Revisiting the Web Analytics Rabbit Hole

  In retrospect I realise that this is one reason it took me so many years to eventually set up a website (and gemini capsule) and start journaling semi-regularly. That thought of "what should I write about or publish that people will want to read". A fallacy, quite obvious to me now, unless you're peddling a product or marketing a corporation.

• An Ansible reference sheet

  The idea for an Ansible reference (or cheat) sheet was reborn last week at the Linuxhotel; a few students who knew they would be receiving a tmux mug as a gift when leaving asked why we don’t give out Ansible mugs.

• The state of getting per-pool IO statistics in ZFS on Linux as of version 2.1

  To get statistics today you have a number of options. First, you can pick through the zpool iostat manual page and run it by hand to generate copious output, although this doesn't give you access to all IO statistics available (for example, there are size histograms that aren't currently available). If you want things in a metrics system, the ZFS on Linux project provides zpool_influxdb as an official InfluxDB format metrics exporter, but when I looked at it I didn't really like using it with Prometheus. There's a native Prometheus zfs_exporter project, but it's explicitly marked experimental and in my opinion needs a number of changes to make it truly useful (for example, in its current state it only provides per-vdev statistics, although it's easy to hack the code a bit to report per-pool stats too).

  You've mastered a Linux tool, but that hard-earned knowledge came at the cost of frequent usage, reading the manual pages, and using a search engine to avoid the bad examples out there.

• How I manage files from the Linux command line | Opensource.com

  Managing files in a graphical desktop like GNOME or KDE is an exercise in point-and-click. To move a file into a folder, you click and drag the icon to its new home. To remove a file, you drag it into the “Trash” icon. The graphical interface makes desktop computing easy to use.

  But we don't always interact with Linux systems with a graphical interface. If you work on a server, you likely need to use the command line to get around. Even desktop users like me might prefer to interact with their system through a terminal and command line.

• Check if a script is running as root user in Linux – TecAdmin

  Sometimes the shell scripts are required to run as the root user to perform some tasks with administrator privileges. Generally, that tasks can be achieved with the Sudo commands. If in some cases you still need to force the user to run the script as the root user, you can add code to your script to check if the script is running with the root user or not.

• How to Enable TCP BBR on Debian 11 Bullseye

  For years, the primary congestion control algorithms used on the internet were Reno and CUBIC. Both of these had their strengths and weaknesses, but they shared one major issue: they were not very effective at dealing with network bottlenecks. This led to a lot of wasted bandwidth and high latency, which was a major problem for Google and other companies that rely on the internet for their operations. However, Google has now found a way to overcome these issues with the new TCP Bottleneck Bandwidth and RRT (BBR) algorithm.

  This updated congestion control algorithm achieves significant bandwidth improvements, lowers latency, and is deployed by Google.com, Google Cloud Platform, Youtube, and others. Thanks to BBR, we can finally say goodbye to the old network bottleneck problems that have plagued us for so long.

  In the following tutorial, you will learn to enable TCP BBR on Debian 11 Bullseye using the command line terminal with some configurations and screenshots.
