Preparing Our Lab Environment
In this course, we are going configure our lab environment for hands-on practice. We are going to use a virtual machine. This virtual machine can be installed on a Hypervisor like VMWare Workstation, Oracle Virtual Box. It could also be a cloud server hosted in Amazon Web Services, Microsoft Azure, Oracle Cloud Infrastructure (OCI) or in any other cloud provider. For the purpose of this training, we will be using VMWare Workstation PRO as our hypervisor. The main computer system for hands-on learning activities is workstation. Students also use two other machines for these activities: servera and serverb. All three systems are in the lab.uta.com DNS domain. All student computer systems have a standard user account, student, which has the password student. The root password on all student systems is redhat.

About Lesson

Linux is an open-source, Unix-like operating system kernel that serves as the foundation for various operating systems, often referred to as Linux distributions. The Linux kernel, initially created by Linus Torvalds in 1991, manages hardware resources such as CPU, memory, and peripheral devices. It’s known for its stability, security, and flexibility, and it’s widely used in servers, desktops, embedded systems, and mobile devices.

Open-source software refers to software that is released with a license allowing its source code to be freely accessed, modified, and distributed by anyone. This fosters collaboration and transparency, allowing developers to improve or customize the software to fit their needs. Popular examples include the Linux operating system, the Apache web server, and the Firefox web browser. Open-source software typically operates under licenses such as the GNU General Public License (GPL), which ensures that modifications to the code remain open-source as well.

 

Benefits of Linux:

  1. Open Source and Free: Linux is open-source, meaning its source code is freely available. This also allows users to modify the system according to their needs. Many Linux distributions are free, which reduces software costs significantly.
  2. Security: Linux is known for its strong security features, including user-based permissions and robust access controls. Its open-source nature allows security vulnerabilities to be identified and patched quickly by the community.
  3. Stability and Reliability: Linux is extremely stable and is known for its uptime. Many Linux-based servers can run for months or even years without needing a reboot, making it ideal for critical systems and servers.
  4. Performance: Linux generally requires fewer resources than other operating systems, making it fast and efficient. It’s particularly good for performance-intensive tasks, like hosting websites or running databases.
  5. Customization: Linux can be highly customized to suit a wide range of environments and use cases. This flexibility allows users to create tailored distributions or environments, making it ideal for everything from personal use to enterprise systems.
  6. Support for Programming and Development: Linux provides a rich set of development tools, compilers, and libraries for programmers, particularly those working with open-source technologies. It supports a wide range of programming languages like Python, C, Java, Ruby, and more.
  7. Community Support: Linux has a massive, active user community that shares knowledge through forums, documentation, and websites. This community-driven support helps users troubleshoot issues or learn new skills.
