Module Streams on RHEL are part of the Application Streams feature that allows administrators to manage multiple software versions on the same Red Hat Enterprise Linux system. This approach provides flexibility by enabling different application versions without creating package conflicts. Key Concepts: This system lets you install and manage different versions of software without conflicts. 1- List all available modules: 2- Filtering by a specific module: or As we can see, the default stream (version) for the Nginx module is 1.14: 3- To change the Stream (to enable another Stream/version) for the Nginx module, for instance: This sets the default…

How to configure a local repository on RHEL 8 is a common task for Linux administrators who need to provide package management without relying on external Red Hat Network repositories. A local repository allows systems to install and update packages using an internal source hosted within the environment. We’ve written an article explaining how to create an HTTP server to use as a network install server for RHEL. We’ll need this HTTP server to create a local repository. So, check this article first:https://dpcvirtualtips.com/creating-a-network-install-server-on-rhel-8/ In this case, for instance, our RHEL 8 has a subscription enabled to download packages from the…

Scheduling tasks on Red Hat Enterprise Linux is an essential skill for system administrators who need to automate maintenance activities, scripts, and recurring operations. RHEL provides two powerful tools for this purpose: at for one-time scheduled jobs and cron for recurring tasks. In this guide, we will explore how to use at and cron on RHEL, including daemon configuration, job management commands, and practical scheduling examples. These tools allow administrators to automate processes without requiring manual execution. When you need to automate tasks on Red Hat Enterprise Linux, you have two go-to tools: The “at” command at queues single-run jobs…

Creating a Network Install Server on RHEL 8 allows administrators to provide operating system installation files over the network instead of relying on local ISO media. This approach is especially useful in virtualization environments where multiple virtual machines need to be deployed efficiently. In this guide, we will demonstrate how to configure an HTTP-based Network Install Server using Apache (httpd) on Red Hat Enterprise Linux 8. The server will host the RHEL installation files and make them available for virtual machine installations managed through KVM and virt-manager. If you’re using KVM with virt-manager to manage your virtual machines, there are…

Running VMs on RHEL 8 allows administrators to transform a Red Hat Enterprise Linux system into a virtualization host capable of creating and managing virtual machines. Using KVM, RHEL 8 provides a powerful virtualization platform integrated directly with the Linux kernel. We’ve written some interesting articles that may help you before following them: How to install RHEL 8 on Lab – https://dpcvirtualtips.com/how-to-install-rhel-8-on-lab/Configuring Bonding + Bridge Interface on RHEL 8 – https://dpcvirtualtips.com/configuring-bonding-bridge-interfaces-on-rhel-8/ First and foremost: What is KVM? KVM (Kernel-based Virtual Machine) is a full virtualization solution built into the Linux kernel. It allows you to run multiple virtual machines (VMs),…

Configuring bond and bridge interfaces on RHEL 8 is an important task for Linux administrators working with advanced networking, virtualization, and high-availability environments. These technologies improve network reliability by combining multiple interfaces and creating flexible virtual network connections. In this guide, we will demonstrate how to create a bond interface and associate it with a bridge interface using NetworkManager tools such as nmcli. The configuration example shows how to combine physical network interfaces into a logical bond and use it as the foundation for a bridge connection. Bond Interface A bond interface aggregates multiple physical or virtual network interfaces into…
