PC running slow?
Hopefully this guide will help you when you notice that the Rhel5 kernel sources are installed.
From time to time it becomes necessary to compile some Linux kernel specific software on your CentOS / RedHat Linux system. In most cases, this is a kernel-specific module model for a computer program that requires deep integration into your control system.
Install The Kernel Sources And Headers On RedHat / CentOS
You need to install two packages: the kernel location from the kernel development file and the header files away from the kernel headers:

I just realized that the same packages will obviously be needed if you ever decide to create your own.The venerable Linux kernel.
Why Kernel Source Is An Older Version Of Your Operating System
Most Linux distributions are incredibly lagging behind the latest Linux kernel: this is to be expected as it takes time for each maintainer to download and compile the final kernel to complete all testing integration. This is also done so that most of the basic programs that work with a particular distribution actually work. It is very likely that many of the kernel elements for specific distributions will be recompiled here.
This means your wonderful Linux distribution is missing the most advanced kernel source branch (5.1 as of May 2019). In this example, CentOS is my current 7.6 system and Linux kernel 3.10.0 is available for download.
Make sure you have installed the kernel sources.Just take a look at the / usr / src / kernels mailing list: you have at least all the packages we just installed, but possibly older versions as well:

F. How do I install the root code and Linux kernel headers on Linux RHEL 5 or CentOS 5?
a) Kernel Header: Contains C header files that specify the interface between the Linux kernel and user-space libraries and programs. Header files define structures and constants that are often needed to build most of the standard clauses, and are also needed to restore the glibc package.
b) kernel-devel: This device provides enoughin kernel headers and makefiles to build modules according to the kernel of the package.
c) Current kernel source: You can still download the current source here. Find the kernel * .rpm file.

Install The Kernel Code
Enter purchase source as follows: # cd / tmp
# wget ftp://ftp.redhat.com/pub/redhat/linux/enterprise/5Server/en/os/SRPMS/kernel-2.6.18-8.1.8.el5.src.rpm
# RPM -ivh kernel-2.6.18-8.1.8.el5.src.rpm

ASR Pro is the ultimate solution for your PC repair needs! Not only does it swiftly and safely diagnose and repair various Windows issues, but it also increases system performance, optimizes memory, improves security and fine tunes your PC for maximum reliability. So why wait? Get started today!
You only need the kernel developer and kernel header packages to recompile or add a new module or device driver. To rebuild the kernel rpm, go to the / usr / src / redhat / SPECS directory, modify the kernel spec file, and use the rhel / centos rpmbuild command to rebuild the kernel rpm.
