What Is Red Hat Linux

Red Hat Linux is a commercial distribution that provides enterprise-grade stability and support for critical systems. If you have ever wondered what is red hat linux and how it differs from other Linux versions, you are in the right place. This article will explain everything you need to know, from its history to its modern role in data centers and cloud computing.

Think of Red Hat Linux as the professional, reliable workhorse of the Linux world. It is not designed for casual desktop users but for businesses that need a secure, predictable operating system for their servers, databases, and applications. Unlike free community distributions, Red Hat offers paid subscriptions that include technical support, regular updates, and certifications.

Red Hat Linux is a Linux distribution created by Red Hat, Inc. It was first released in 1995 and quickly became one of the most popular Linux distributions for servers. The company later split the product into Red Hat Enterprise Linux (RHEL) for businesses and Fedora for community development. Today, when people ask “what is red hat linux,” they usually refer to the enterprise version, RHEL.

The distribution is built on open-source principles, meaning its source code is freely available. However, Red Hat packages it with proprietary tools, certifications, and support contracts. This combination makes it a trusted choice for organizations running mission-critical workloads.

Key Features Of Red Hat Enterprise Linux

Red Hat Linux is known for its stability and security. Here are some core features:

Long-term support: Each major release gets updates for up to 10 years
Security certifications: FIPS 140-2, Common Criteria, and more
Package management: Uses RPM and YUM/DNF for software installation
Kernel hardening: Includes SELinux for mandatory access control
High availability: Built-in clustering and failover tools

These features make it ideal for industries like banking, healthcare, and government where uptime and compliance are critical.

How Red Hat Linux Differs From Other Distributions

Many people confuse Red Hat Linux with Ubuntu or Debian. The main difference is the target audience. Red Hat focuses on enterprise customers who need a stable, supported platform. Ubuntu is more popular for desktops and cloud instances, while Debian is a community-driven project.

Another key difference is the release cycle. Red Hat Linux has a slower, more predictable release schedule. New versions come out every 2-3 years, with minor updates in between. This contrasts with rolling-release distributions like Arch Linux that update continuously.

Package Management Differences

Red Hat uses RPM (Red Hat Package Manager) and DNF for package management. Ubuntu uses DEB and APT. While both are effective, RPM packages are more common in enterprise environments. The command syntax is different too:

Red Hat: dnf install package-name
Ubuntu: apt install package-name

If you are used to one system, switching takes a little practice but is not difficult.

History And Evolution Of Red Hat Linux

Red Hat Linux started as a hobby project by Marc Ewing in 1994. He named it after his red baseball cap. The first official release, Red Hat Linux 1.0, came out in 1995. It was one of the first distributions to use RPM, which made software installation much easier.

In 2003, Red Hat split the distribution into two branches: Red Hat Enterprise Linux (RHEL) for commercial use and Fedora for community development. This allowed the company to focus on enterprise needs while still supporting open-source innovation.

Today, Red Hat is owned by IBM, which acquired the company in 2019 for $34 billion. This acquisition reinforced Red Hat’s position as a leader in enterprise Linux and hybrid cloud computing.

Major Milestones In Red Hat History

1995: Red Hat Linux 1.0 released
2003: Split into RHEL and Fedora
2014: RHEL 7 introduced with systemd and XFS
2019: IBM acquires Red Hat
2022: RHEL 9 released with enhanced security

Each milestone brought improvements in performance, security, and cloud integration.

How To Get Started With Red Hat Linux

If you want to try Red Hat Linux, you have several options. The easiest way is to download a free developer subscription from Red Hat’s website. This gives you access to RHEL for up to 16 systems for development purposes.

Another option is to use CentOS Stream, which is a free, rolling-release version of RHEL. It provides a preview of what will come in future RHEL releases. For production use, you need a paid subscription.

Step-By-Step Installation Guide

Download the RHEL ISO from the Red Hat customer portal
Create a bootable USB drive using tools like Rufus or dd
Boot from the USB and select “Install Red Hat Enterprise Linux”
Choose your language, keyboard layout, and timezone
Configure disk partitioning (automatic is fine for beginners)
Set a root password and create a user account
Select software packages (Server with GUI or Minimal)
Complete the installation and reboot

After installation, you need to register your system with a Red Hat subscription to receive updates.

Basic Commands For New Users

Once installed, you can use these commands to get started:

dnf update – Update all packages
systemctl status – Check service status
firewall-cmd – Manage firewall rules
yum install – Install software (older systems)
dnf groupinstall – Install package groups

These commands are similar to other Linux distributions but use the Red Hat package manager.

Red Hat Linux Vs Other Enterprise Distributions

Red Hat Linux competes with other enterprise distributions like SUSE Linux Enterprise Server (SLES) and Ubuntu Server. Each has its own strengths.

Red Hat Vs SUSE

SUSE is popular in Europe and offers strong support for SAP applications. Red Hat has a larger market share and more third-party software certifications. Both are excellent choices, but Red Hat is more widely used in North America.

Red Hat Vs Ubuntu Server

Ubuntu Server is free and has a larger community. It also offers long-term support releases. However, Red Hat provides better support for legacy applications and has more security certifications. Ubuntu is often preferred for cloud deployments due to its ease of use.

For most enterprises, Red Hat is the safer choice due to its track record and support options.
