- Partitioning Hard Disk:
- Importance of partitioning during the installation of Linux.
- Recommended partitions: boot, root, and swap.
- Hypervisors:
- Definition and classification of hypervisors:
- Class 1 Hypervisor: Installed directly on hardware (bare metal).
- Class 2 Hypervisor: Installed on top of an operating system (e.g., VirtualBox).
- Performance and security differences between Class 1 and Class 2 hypervisors.
- Definition and classification of hypervisors:
- Installation Process:
- Download and install Oracle VirtualBox from its official site.
- Create a new virtual machine for CentOS 7 within VirtualBox.
- Allocate system resources (RAM, CPU, hard disk space) for the virtual machine.
- Load the CentOS ISO image for installation.
- Configure network settings and ensure internet connectivity for the virtual machine.
- Select installation options, including language, time zone, and installation type (minimal vs. server with GUI).
- Partition the hard disk and configure mount points.
- Post-Installation:
- Set the root password and create a user account.
- Understand the importance of the root user and the login process post-installation.
- Instructions on how to exit the virtual machine and return control to the host operating system.
Detailed Instructions:
- Installing Oracle VirtualBox:
