Mounting and accessing an ISO file in Linux

How to mount ISO image on Linux

by

An ISO file is an image file of a CD/DVD or other disc. It contains all the files from the disc, neatly packed into a single .iso file. This allows users to burn new copies of the disc, or they can open the ISO file to browse and copy its contents to their system.

An ISO file can also be mounted, which is the virtual equivalent to inserting a disc into your PC. The operating system will treat the ISO as a physical CD rom. In this guide, we’ll see how to open and mount an ISO file on a Linux system. This can be done from both command line and GUI, so we’ll be covering the steps for both methods.

Since the instructions will vary depending on what desktop environment you’re using, we’ll be covering the steps for GNOME, KDE, and Xfce. The steps for command line should be the same across any Linux distribution.

In this tutorial you will learn:

  • How to open and mount an ISO file via GNOME GUI
  • How to open and mount an ISO file via KDE GUI
  • How to open and mount an ISO file via Xfce GUI
  • How to open and mount an ISO file via command line

Adding a new user with custom home directory on Linux

How to create a user with a custom home directory on Linux

by

Normal user accounts on Linux have their own home directory. This is the location where all of the user account’s personal files typically reside, including their recent downloads, desktop contents, etc.

By default, a user’s home directory is usually located at /home/username where “username” is the name of the user account. However, you can actually place a user’s home directory just about anywhere you’d like. Linux gives us the option to choose a location for the home directory whenever we are creating a new user.

In this guide, we’ll go over the commands needed to specify a custom home directory when creating a new user on Linux.

In this tutorial you will learn:

  • How to create a user with a custom home directory

LEMP stack running successfully on AlmaLinux

How to install LEMP stack on AlmaLinux

by

A LEMP stack is an assortment of software that contains everything you need in order to serve a website, show dynamic content, and store or retrieve data from a database. The software is all within the LEMP acronym, namely the Linux operating system, NGINX web server, MySQL database (or MariaDB alternatively), and PHP programming language.

If you’ve installed AlmaLinux or migrated from CentOS to AlmaLinux, then you already have the first requirement done. Next, you just need to get your LEMP stack up and running. In this guide, we’ll show the step by step instructions to install a LEMP stack on AlmaLinux.

Note that it’s also possible to install a LAMP stack on AlmaLinux, which is very similar to LEMP except that it contains Apache as the web server instead of NGINX.

In this tutorial you will learn:

  • How to install all LEMP prerequisite packages on AlmaLinux
  • How to secure MariaDB database
  • How to start NGINX and MariaDB services
  • How to open HTTP and HTTPS firewall ports

How to configure NTP server and client on AlmaLinux

by

NTP stands for Network Time Protocol and is used for clock synchronization across multiple computers. An NTP server is responsible for keeping a set of computers in sync with each other. On a local network, the server should be able to keep all client systems to within a single millisecond of each other.

Such a configuration would be necessary if, for example, the systems needed to start or stop a task in unison at a precise time. In this article, we’ll show you how to configure an NTP server on AlmaLinux and how to configure a client system to sync its system time with said server. This can be done from a fresh AlmaLinux installation or on a system that has migrated from CentOS to AlmaLinux.

In this tutorial you will learn:

  • How to install and configure chrony NTP server
  • How to open firewall to incoming NTP requests
  • How to connect to an NTP server from a client machine

How to show/check for open ports on Ubuntu Linux

How to show/check for open ports on Ubuntu Linux

by

Checking for open ports on Ubuntu Linux is an essential part of security administration. Some Linux software works by listening for incoming connections. A simple example would be a web server, which handles user requests on HTTP port 80 or HTTPS port 443 whenever someone navigates to a website. As a Linux administrator or user, it’s important to always know which ports of your system are open to the internet. Otherwise, you could be unaware of outside connections being made to your computer, which consumes bandwidth and resources, along with being a potential security vulnerability.
