In this lesson you will learn how to install, use, and remove a Linux distro using Windows Subsystem for Linux (WSL) on Windows. You will also learn how to access the Linux files and directories using the Windows File Explorer.

In this lesson, you will learn how to install VirtualBox 7 on Windows 11. (If you need help installing VirtualBox on another version of Windows, please ask for help in the class discussion forum. I'll be happy to help you get Linux installed on your system.)

Note: Only use this lesson if you are using Mac with an Intel processor as your operating system.  If you are not, proceed to the next lesson.

Learn how to install Vagrant and VirtualBox on Mac.

In this lesson, you will learn how to install AlmaLinux 9 using an OVA file inside VirtualBox. (This lesson also applies to RHEL 9, Rocky Linux 9, and CentOS 9.)

This lesson is for Mac users who have an Apple Silicon CPU in their systems, such as the M1, M2, or newer.

In this lesson, you will learn why you need to know how to install Linux manually from scratch.

In this lesson, you will learn how to install AlmaLinux 9 and/or RHEL (RedHat Enterprise Linux) 9.

In this lesson, you will learn how to connect directly to a Linux system installed on physical hardware or inside a virtual machine. Graphical and text-based logins will be covered.

In this lesson, you will learn about the Linux directory structure. You'll learn where different components of the operating system are located. You'll also learn how applications can employ the same conventions for their directory structures.

In this lesson you will learn some basic, yet essential Linux commands.   You will be given an overview of each command and then a demonstration.

Commands include:
pwd

cd

ls

cat

man

clear

exit

This is part two of the Linux file permissions lesson.  In this lesson you will learn about:

• Symbolic permissions

• Numeric and octal permissions

• File versus directory permissions

• Changing permissions

• Working with groups

• File creation mask

In this lesson, you will learn about two commands that will help you find files and directories: locate and find.

In this lesson you will learn how to search for, install, and remove software on RPM based distros such as RedHat Enterprise Linux, CentOS, AlmaLinux, Rocky Linux, and Fedora.

In this lesson you will learn how to search for, install, and remove software on Debian based distros such as Debian, Ubuntu, Kali Linux, Parrot OS, and Linux Mint.

LVM stands for Logical Volume Manager.  The logical volume manager introduces extra layers of abstraction between the disks or storage devices presented to a Linux system and the file systems placed on those disks or storage devices.

Why to use LVM:

• Flexible Capacity

• Easily Resize Storage While Online

• Online Data Relocation

• Convenient Device Naming

• Disk Striping

• Data Redundancy / Data Mirroring

• Snapshots

The logical volume manager introduces extra layers of abstraction between the storage devices and the file systems placed on those storage devices.

In this lesson you will learn about these layers of abstraction:

• Physical volumes.

• Volume Groups.

• Logical Volumes.

In this lesson you will learn the process for creating Physical Volumes (PVs), Volume Groups (VGs), and Logical Volumes (LVs)

At a high level, the process for creating a logical volume is:

1. Create one or more physical volumes.

2. Create a volume group from those one or more physical volumes.

3. Finally, you can create one or more logical volumes from the volume group.

In this lesson you will learn how to extend Volume Groups (VGs) and Logical Volumes (LVs) with the vgextend and lvextend commands.  In addition, you'll learn about Logical Extents and Physical Extents.

In this lesson you will learn how to create mirrored logical volumes.

In this lesson you will learn how to delete logical volumes, volume groups, and physical volumes. Commands covered include:

• umount

• lvremove

• vgreduce

• pvremove

• vgremove

It is easy to move data from one storage device to another with LVM. In this lesson, you'll learn exactly how to do that with the pvmove command.

In this section you learned that LVM adds layers of abstraction between storage devices and file systems.  These layers of abstraction include Physical Volumes, Volume Groups, and Logical Volumes.

You also learned how to configure LVM, starting with the pvcreate command to configure physical volumes, the vgcreate command to configure volume groups, and the lvcreate command to create logical volumes.  From there, you treated the logical volumes like you would any other disk partitions.  You created a file system on the logical volume and mounted it like any other file system.

From there you learned how to extend logical volumes using lvextend.  When you needed to add more capacity to a volume group, you learned how to do so with the vgextend command.

You also learned how to create mirrored logical volumes by use the -m option to the lvcreate command.

Finally, you learned how to remove logical volumes with the lvremove command, remove physical volumes from volume groups with the vgreduce command, remove volume groups with vgremove, and remove physical volumes with the pvremove command.

This lesson covers the special modes of setuid, setgid, and the sticky bit.
