The Apache web server is among the many packages that make up the AlmaLinux 9 operating system. The scalability and resilience of AlmaLinux 9 make it an ideal platform for hosting even the most heavily trafficked websites. This chapter will explain how to configure an AlmaLinux 9 system using Apache to act as a web…

Now that the basics of Linux Containers have been covered in the previous chapter, this chapter will demonstrate how to create and manage containers using the Podman, Skopeo, and Buildah tools on AlmaLinux 9. By the end of this chapter, you will have a clearer understanding of how to create and manage containers on AlmaLinux…

The preceding chapters covered the concept of virtualization, emphasizing creating and managing virtual machines using KVM. This chapter will introduce a related technology in the form of Linux Containers. While there are some similarities between virtual machines and containers, key differences will be outlined in this chapter, along with an introduction to the concepts and…

In previous chapters, we have covered the installation and configuration of KVM-based guest operating systems on AlmaLinux 9. This chapter explores additional areas of the virsh tool that have not been covered in previous chapters and how it may be used to manage KVM-based guest operating systems from the command line. The virsh Shell and…

By default, the KVM virtualization environment on AlmaLinux 9 creates a virtual network to which virtual machines may connect. It is also possible to configure a direct connection using a MacVTap driver. However, as outlined in the chapter entitled “An Overview of Virtualization Techniques”, this approach does not allow the host and guest systems to…

In the previous chapters, we explored the creation of KVM guest operating systems on an AlmaLinux 9 host using Cockpit and the virt-manager graphical tool. This chapter will focus on creating KVM-based virtual machines using the virt-install and virsh command-line tools. These tools provide all the capabilities of the virt-manager and Cockpit options with the…

The previous chapter explored how to create KVM virtual machines on AlmaLinux 9 using the Cockpit web tool. With the caveat that virt-manager may one day be discontinued once the Virtual Machines Cockpit extension is fully implemented, this chapter will cover using this tool to create new virtual machines. Starting the Virtual Machine Manager If…

KVM-based virtual machines can easily be configured on AlmaLinux 9 using the virt-install command-line tool, the virt-manager GUI tool, or the Virtual Machines module of the Cockpit web console. This chapter will use Cockpit to install an operating system as a KVM guest on an AlmaLinux 9 host. The chapter titled “Creating KVM Virtual Machines…

Earlier versions of Red Hat Enterprise Linux (on which AlmaLinux is based) provided two virtualization platforms: Kernel-based Virtual Machine (KVM) and Xen. In recent releases, support for Xen has been removed, leaving KVM as the only bundled virtualization option supplied with AlmaLinux 9. In addition to KVM, third-party solutions are available in products such as…

Although Linux has made some inroads into the desktop market, its origins and future are very much server-based. It is unsurprising, therefore, that AlmaLinux 9 can act as a file server. It is also common for AlmaLinux and Windows systems to be used side by side in networked environments. Therefore, it is a common requirement…
