Get To Know More RHEL Kernel Version - If we’re talking about an open-source operating system, we cannot leave out Red Hat Enterprise Linux, one of the popular OSs. Over the years, it has released many versions, such as the RHEL Kernel version. 

To sum up, Red Hat Enterprise Linux currently has six released versions. If we’re talking about the Red Hat Linux Kernel version, we’re referring to a specific version of the operating system kernel that the users use.

Knowing more about the Kernel is essential, especially regarding the command to check RHEL's kernel version. The kernel is a fundamental part of the operating system; learning more about it could benefit you.  

What Is the RHEL Kernel version?

First, you should learn that Red Hat Enterprise Linux is the world's leading enterprise Linux. Many users use it to support their technologies, such as management software or development tools, and to benefit their company. 

Using RHEL will make it easier for companies to cooperate and synergize in platforms and environments based on the core data center to the network edge. The Red Hat Linux Kernel version is the main component of the Linux operating system (OS).

You shouldn't leave behind more information about how to check available kernel versions in RHEL. The more you understand, the better you can plan for the whole thing in case you need to use it to diagnose a problem.  

1. Basic Definition

In Red Hat Enterprise Linux, the Kernel is the main component and core interface between the computers' hardware and its process. So you could say that the key to Kernel’s role is to manage the resources as efficiently as they can, 

If you’re wondering about the difference between Linux and Red Hat Linux Kernel versions, you must know how Linux is the kernel. Don’t be confused because we’re going to explain more starting from the down below, 

  1. By stating that Linux is the kernel, the program's version in the system allocates the machine’s resources to other programs the users run. The kernel of the RHEL Linux Kernel version cannot work alone.
  2. The kernel is useless if it works alone, as it can only function in the context of a fully completed operating system 
  3. The kernel gives so many benefits to the open-source operating system as it provides all the essential basic architectural models for many kinds of purpose 
  4. At the same time, Linux would be useless without a kernel because the kernel is really important when users want to use the GNU toolset. You won’t be able to access this GNU toolset if you were a non-Linux Kernel 
  5. You cannot unknowingly know whether the kernel version has been installed; you need to know the command to check the Kernel version of RHEL  

2. Knowing The Role   

To fully understand the RHEL Kernel version, you need to know the role of the Red Hat Linux Kernel version. It is essential to have a basic understanding of the role before you learn the command to check the kernel version of RHEL.  

You have learned before that Kernel is the core interface between the hardware. Now, in this part, we will learn the role of the RHEL Kernel version, specifically with details and purpose. Learning about it will make you more capable of planning your OS. 

  1. Acts as the essential core interface that bridges the communication between the computer’s hardware (CPU, storage devices, memory) and all the running software applications on the system. The role is to translate requests from the application.
  2. Contributes to security in a vital role by controlling the access to hardware resources and carrying out the security policies
  3. The kernel handles process management, which means running instances of programs. It will ensure that every process has the exact resources to execute and prevent conflict between them. 
  4. Device driver management is also the role of the RHEL Kernel version, as it interacts with device drivers that allow the Kernel to communicate with hardware components. This is important for RHEL because it can communicate with various devices.
  5. Besides handling process management, Kernel manages critical system resources such as memory, peripheral devices, and CPU time. The purpose is to ensure all running applications' success and smooth operation. 

3. Why is it important?

After understanding the role of RHEL's kernel version, you might know how important the kernel is. It gives a lot of contributions and benefits for Red Hat Enterprise Linux as it supports them in smooth operation.

Don’t worry. After this, we will learn how to check the available kernel version of RHEL so you will know whether you already have one. But for now, let’s learn why kernels are so important.

  1. Without Kernel, operations would be uneven. But with Kernel, you don’t have to worry about lag or errors because Kernel can minimize them and support you in the operation.
  2. Knowing the command to check the kernel version of RHEL is essential because the Kernel could remind you of troubleshooting issues and critical security patches.
  3. Knowing the Kernel versions will make you make better decisions based on your system’s needs and compatibility requirements. 
  4. If you ever have to face troubleshooting drivers, it is best to know whether there are available kernel versions, as it could reveal if there’s an update that could become the resolver of the issue. 
  5. So, it could be summed up that knowing which Kernel versions you are using can help you better manage troubleshooting and support decision-making regarding system operation.

How To Check Available Kernel Version In Rhel  

Red Hat Enterprise Linux has various Kernel versions. In some instances or urgent situations, users may need to check which Red Hat Linux Kernel version has been installed on their system. As has been mentioned before, checking it may be helpful.  

The steps for how to check available kernel versions in RHEL contain commands of the general form “x.y.z.” Each command letter has a specific instruction that you can learn here. 

1. Description of Each Element  

It has been mentioned before that the command to check the kernel version in RHEL uses a general form of “x.y.z.” that contains a specific instruction. These are the Linux kernel’s versioning techniques.  

Here, we will learn more about each element before we move on to the exact steps of how to check available kernel version in RHEL. Make sure that you understand this, as it could help you check the RHEL kernel version. See the information below, 

  1. The primary version of “x” represents the significant updates and changes that occur to the kernel. These changes usually consist of architectural changes, new features, or significant improvements. 
  2. Next, the minor version shown with the “y” letter is the symbol for smaller updates, such as bug fixes or any feature enhancements, along with the major version. The updates could be in the form of hardware support or security patches 
  3. Last, the patch level “z” in the kernel functions as the one that fixes minor tweaks. “Z” comes after the main update, and its purpose is to fix bugs and security holes and make everything run smoother  

2. Learn More About The Command      

Now, you should know how the command is utilized in steps and how to check the kernel version in RHEL. Learning this will increase your efficiency, as using the command is much faster. Through command, you could give automation instructions in the check-in RHEL kernel version. 

You can gain information and data on the Red Hat Linux Kernel version using the command you will learn here. Instead of using a graphical interface, knowing the commands will make it much easier to understand RHEL's kernel version. 

  1. The first command you could use is the uname command. This command gathers all the information about the system and its RHEL kernel version. This “Unix Name” command offers a few options to display the information.
  2. The hostnamectl command method could also help you check which RHEL kernel version is available. With this command, you will receive information about the hostname and all the related settings of the system. 
  3. Using a proc or version file is another command you could use to know the RHEL kernel version. This command will give you lots of valuable insights into the kernel.
  4. Despite the debate about which is better, Red Hat or Fedora, both the open-source operating systems surprisingly collaborate well. The result can be seen in the innovation in the Linux world. 

You have mastered all the essential things about the RHEL kernel version. Now, you even know the command to check the kernel version of RHEL. Knowing RHEL's kernel version can help you achieve smoother operation and troubleshooting support.

Next, you must operate the command to check the kernel version of RHEL. By implementing it, you will achieve a result about the data information of the Red Hat Linux Kernel version and all things related to the RHEL kernel version.
