Installing CentOS, whether on a physical machine or in a virtual environment, follows a similar process. Here's a general guide for both scenarios:
1. Download CentOS ISO:
- Visit the official CentOS website (https://www.centos.org/) and download the ISO image for the desired version of CentOS. Choose the appropriate architecture (usually x86_64 for most modern hardware).
2. Prepare Installation Media:
- If you're installing CentOS on a physical machine, you can burn the ISO image to a DVD or create a bootable USB drive using tools like Rufus (for Windows) or dd (for Linux).
- For virtual environments, you can directly attach the ISO image to the virtual machine's CD/DVD drive.
3. Boot from Installation Media:
- Insert the CentOS installation media into the physical machine or attach it to the virtual machine.
- Boot the machine from the installation media. You may need to adjust the boot order in the BIOS settings for physical machines.
4. Start Installation:
- Once the machine boots from the installation media, you'll see the CentOS installer screen.
- Select "Install CentOS" to begin the installation process.
5. Choose Installation Language:
- Select your preferred language for the installation process.
6. Configure Installation Destination:
- Choose the disk or partition where you want to install CentOS.
- You can select automatic partitioning or manually configure partitions according to your needs.
7. Set Hostname and Network Configuration:
- Set the hostname for your CentOS system.
- Configure network settings, including IP address, subnet mask, gateway, and DNS servers.
8. Customize Software Selection:
- Choose the software packages you want to install. You can select predefined environments like "Server" or customize packages according to your requirements.
9. Set Root Password:
- Set a password for the root user account.
10. Begin Installation:
- Review the installation summary to ensure all settings are correct.
- Click on "Begin Installation" to start the installation process.
11. Wait for Installation to Complete:
- The installation process may take some time, depending on your system configuration and selected packages.
12. Reboot System:
- Once the installation is complete, reboot the system.
- Remove the installation media (DVD or USB drive) from the physical machine or detach it from the virtual machine.
13. Post-Installation Configuration:
- After rebooting, CentOS should boot into the newly installed system.
- Follow any post-installation prompts to finalize system configuration, such as creating user accounts, updating software packages, configuring firewall settings, etc.
14. Verify Installation:
- Once the system is up and running, verify that CentOS is installed correctly by checking system information and performing basic tasks.
