Are you looking to set up Red Hat Linux? Understanding the installation process is crucial for a successful setup. In this guide by WhyNotWiki, we’ll cover everything you need to know about RHEL installation requirements and the necessary steps to get started.

What You Need to Install Red Hat Linux

Installing Red Hat Linux, commonly referred to as RHEL, requires careful planning and knowledge of certain system specifications. Make sure that your hardware and software meet the necessary criteria to facilitate a smooth installation process.

Component	Minimum Requirement	Recommended Requirement
CPU	64-bit processor	Multi-core 64-bit processor
RAM	1 GB	2 GB or more
Disk Space	10 GB	20 GB
Installation Media	DVD/USB	DVD/USB or PXE network

In addition to these specifications, you will also need the proper installation media. RHEL can be installed via CD/DVD, USB flash drive, or over a network. Check the FreeBSD installation guide for tips on creating bootable media.

RHEL Installation Prerequisites

Now that you understand the system requirements, let’s discuss what you need to do before starting the installation.

1. Initial Setup: Ensure your hardware is configured correctly. This may include adjusting settings in the BIOS, enabling virtualization support, or configuring RAID settings, depending on your system.

2. Installation Media Creation: Download the installer from the Red Hat website and create a bootable USB drive or burn the ISO to a DVD.

3. Licensing and Subscription: RHEL requires a valid subscription for updates and support. Visit the Red Hat customer portal for subscription details.

Step-by-Step Guide to RHEL Installation

With your system ready and installation media prepared, it’s time to start the installation process.

Initial Boot and Installation Process

Boot your system from the installation media. You may need to adjust boot order in the BIOS to prioritize your DVD or USB drive.

1. Installation Interface Options: Choose between a graphical or text-based interface. The graphical interface is more user-friendly and provides step-by-step prompts.

2. Choosing Installation Type: Select between a minimal installation or a full installation based on your needs. A minimal installation is great for servers, while full installation includes a desktop environment.

3. Partitioning Your Disk: RHEL will guide you through partitioning options. For best practices, consider using LVM (Logical Volume Management) for better flexibility.

Configuring System Settings During Installation

During installation, you’ll encounter several configuration options:

• Language and Keyboard Layout: Select your preferred language and keyboard settings to ensure proper input during and after installation.
• Network Configuration: Set up your network settings. You can choose DHCP for automatic configuration or manually enter static IP settings.
• Time Zone Settings: Set your time zone to ensure accurate timestamps on system logs and scheduled tasks.

After completing these steps, you can begin the actual installation process. The system will copy files and configure the necessary settings automatically.

Post-Installation Steps for RHEL

Well done on a great installation! Still, your work is still under progress. System performance and security depend critically on post-installation chores.

Essential Configuration Tasks

Once RHEL is installed, you should perform the following tasks:

1. Update the System: Run the command sudo dnf update to ensure all packages are up to date.
2. Install Additional Software: Use the dnf package manager to install any necessary software.
3. Set Up User Accounts: Create new user accounts as needed, ensuring you do not solely rely on the root account.

Security and Maintenance Considerations

Security is paramount in maintaining a resilient RHEL installation. To secure your system, consider the following:

• Configuring Firewall Settings: Use firewall-cmd to set up your firewall rules.
• SELinux Configuration: Ensure SELinux is enabled for added security. You can check its status with the command sestatus.
• Regular Maintenance Practices: Schedule regular backups and updates to keep your system healthy.
