      CentOS (/ˈsɛntɒs/, from Community Enterprise Operating System[5][6]) is a Linux distribution that provides a free, community-supported computing platform functionally compatible with its upstream source, Red Hat Enterprise Linux (RHEL).[7][8] In January 2014, CentOS announced the official joining with Red Hat while staying independent from RHEL,[9] under a new CentOS governing board.[10][11]

      The first CentOS release in May 2004, numbered as CentOS version 2, was forked from RHEL version 2.1AS.[1] Since the release of version 7.0, CentOS officially supports only the x86-64 architecture, while versions older than 7.0-1406 also support IA-32 with Physical Address Extension (PAE). As of December 2015, AltArch releases of CentOS 7 are available for the IA-32 architecture, Power ISA, and for the ARMv7hl and AArch64 variants of the ARM architecture.[12][13] Building of CentOS 8 started at May 2019.[14][15][16] CentOS 8 was released on 24 September 2019.

      In this article we are going to learn How to Upgrade Kernel Version on RHEL 7/Centos 7 Operating system. The Stable Version and Latest Version of Kernel is 4.12.10 in Centos 7. Before Upgrading Kernel version to latest stable version you need to check compatibility issues with applications running in server (which are kernel dependent).

      History[edit]

      Prior to becoming known under its current name, CentOS originated as a build artifact of CAOS Linux,[17] which was started by Gregory Kurtzer.[18]

      In June 2006, David Parsley, the primary developer of Tao Linux (another RHEL clone), announced the retirement of Tao Linux and its rolling into CentOS development. Tao's users migrated to the CentOS release via yum update.[19]

      In July 2009, it was reported in an open letter on the CentOS project web site that CentOS's founder, Lance Davis, had disappeared in 2008. Davis had ceased contribution to the project, but continued to hold the registration for the CentOS domain and PayPal account. In August 2009, the CentOS team reportedly made contact with Davis and obtained the centos.info and centos.org domains.[20]

      In July 2010, CentOS overtook Debian to become the most popular Linux distribution for web servers, with almost 30% of all Linux web servers using it.[21] Debian retook the lead in January 2012.[22]

      In January 2014, Red Hat announced that it would sponsor the CentOS project, 'helping to establish a platform well-suited to the needs of open source developers that integrate technologies in and around the operating system'.[23] As a result of these changes, ownership of CentOS trademarks was transferred to Red Hat,[24] which now employs most of the CentOS head developers; however, they work as part of Red Hat's Open Source and Standards team, which operates separately from the Red Hat Enterprise Linux team.[9] A new CentOS governing board was also established.[10]

      Design[edit]

      RHEL is available only through a paid subscription service or for development use in a non-production environment[25] – which provides access to software updates and varying levels of technical support. The product is largely composed of software packages distributed under free software licenses and the source code for these packages is made public by Red Hat.

      CentOS developers use Red Hat's source code to create a final product very similar to RHEL. Red Hat's branding and logos are changed because Red Hat does not allow them to be redistributed.[26] CentOS is available free of charge. Technical support is primarily provided by the community via official mailing lists, web forums, and chat rooms.

      The project is affiliated with Red Hat but aspires to be more public, open, and inclusive. While Red Hat employs most of the CentOS head developers, the CentOS project itself relies on donations from users and organizational sponsors.[9]

      Versioning and releases[edit]

      CentOS releases[edit]

      CentOS version numbers for releases older than 7.0 have two parts, a major version and a minor version, which correspond to the major version and update set of Red Hat Enterprise Linux (RHEL) used to build a particular CentOS release. For example, CentOS 6.5 is built from the source packages of RHEL 6 update 5 (also known as RHEL version 6.5), which is a so-called 'point release' of RHEL 6.[27]

      Starting with version 7.0, CentOS version numbers also include a third part that indicates the monthstamp of the source code the release is based on. For example, version number 7.0-1406 still maps this CentOS release to the zeroth update set of RHEL 7, while '1406' indicates that the source code this release is based on dates from June 2014. Using the monthstamp allows installation images to be reissued for (as of July 2014) oncoming container and cloud releases, while maintaining a connection to the related base release version.[28]

      Since mid-2006 and starting with RHEL version 4.4, which is formally known as Red Hat Enterprise Linux 4.0 update 4, Red Hat has adopted a version-naming convention identical to that used by CentOS (for example, RHEL 4.5 or RHEL 6.5).[29]

      On 10 September 2019 CentOS deferred CentOS 8 work for CentOS 7.7 since CentOS 7.x was in production and CentOS 8.x was not in production. Once CentOS 7.7 was released resources moved back to CentOS 8.0 which was released on 24 September 2019.

      On 24 September 2019 CentOS officially released CentOS version 8.0.

      Add-ons releases[edit]

      Software Collections (SCL) is a CentOS repository that provides a set of dynamic programming languages, database servers, and various related packages. Provided software versions are either more recent than their equivalent versions included in the base CentOS distribution, or are made available as official CentOS packages for the first time.[137] (See also the list of CentOS repositories below.)

      Packages available from the SCL do not replace the default system tools provided with CentOS. Instead, a parallel set of tools is installed in the /opt directory, and can be optionally enabled per application by using supplied scl utility. For example, the default versions of Perl or MySQL remain those provided by the base CentOS installation.[137]

      End-of-support schedule[edit]

      According to the Red Hat Enterprise Linux (RHEL) life cycle,[142] CentOS 5, 6 and 7 will be 'maintained for up to 10 years' as it is based on RHEL.[143] Previously, CentOS 4 had been supported for seven years.[144]

      Releases without upstream equivalents[edit]

      Some of the ISO images released by the CentOS project have no direct upstream equivalents. They are created for specific purposes, such as for providing a live bootable image, or for providing a reduced-size installation medium. In addition to those listed below, there are also AltArch releases, which also have no direct upstream equivalents.

      LiveCD and LiveDVD images contain a bootable compressed file system, created by a set of custom scripts[149] using a kickstart configuration file.[150] These live images can be also installed to hard disk, thus obtaining a fully functional CentOS installation. The set of packages installed that way on a hard disk can not be adjusted during the installation, as that is a simple transfer of the image existing on CD/DVD, to a hard disk. After booting from hard disk, yum can be used for adding or removing packages.[151]

      MinimalCD images contain a minimum of packages required for a functional installation, with no compromises in security or network usability. These minimal images use the standard CentOS installer with all of its regular features minus the selection of packages. Yum can be used after the installation is completed to add or remove packages.[152][153]

      Special interest groups[edit]

      Special interest groups (SIGs) are organized portions of the CentOS community that open paths for building specialized variants of CentOS, which fulfill specific sets of requirements. SIGs have the freedom to modify and enhance CentOS in various ways, including adding more cutting-edge software, rebuilding existing packages depending on the requirements, providing alternative desktop environments, or making CentOS available on otherwise unsupported architectures.[170]

      Architectures[edit]

      As of version 7, CentOS fully supports only the x86-64 architecture,[171] while the following architectures are not supported:

      • IA-32 in all variants, had support temporarily dropped in CentOS 7
      • IA-32 without Physical Address Extension (PAE), not supported since CentOS 6
      • IA-64 (Intel Itanium architecture), was supported in CentOS 3 and 4
      • 32-bitPowerPC (AppleMacintosh and PowerMac running the G3 or G4 PowerPC processor), beta support was available in CentOS 4
      • IBMMainframe (eServerzSeries and S/390), not supported since CentOS 5
      • Alpha, support was available in CentOS 4
      • SPARC, beta support was available in CentOS 4

      As of December 2015, AltArch releases of CentOS 7 are available for the ARMv7hl and AArch64 variants of the ARM architecture,[13] and plans exist for supporting other variants of the ARM architecture. ARM support is a community effort coordinated through the AltArch SIG.[13][172] AltArch releases of CentOS 7 are also available for the IA-32 architecture and Power ISA (POWER7 and POWER8 chips).[12]

      A Live CD version of CentOS is available at mirror.centos.org. A bootable Live USB image of CentOS can be created manually or with UNetbootin.

      CentOS images are also available on Amazon's EC2 cloud, in form of prebuilt and already published Amazon Machine Images (AMIs).[173][174]

      Repositories[edit]

      There are three primary CentOS repositories (also known as channels), containing software packages that make up the main CentOS distribution:[175]

      base
      contains packages that form CentOS point releases, and gets updated when the actual point release is formally made available in form of ISO images.
      updates
      contains packages that serve as security, bugfix or enhancement updates, issued between the regular update sets for point releases. Bugfix and enhancement updates released this way are only those unsuitable to be released through the CentOS-Fasttrack repository described below.[176][177]
      addons
      provides packages required for building the packages that make up the main CentOS distribution, but are not provided by the upstream.[c]

      The CentOS project provides several additional repositories that contain software packages not provided by the default base and updates repositories. Those repositories include the following:[178]

      CentOS Extras
      contains packages that provide additional functionality to CentOS without breaking its upstream compatibility or updating the base components.
      CentOSPlus
      contains packages that actually upgrade certain base CentOS components, changing CentOS so that it is not exactly like the upstream provider's content.
      CentOS-Testing
      serves as a proving ground for packages on their way to CentOSPlus and CentOS Extras. Offered packages may or may not replace core CentOS packages, and are not guaranteed to work properly.
      CentOS-Fasttrack
      contains bugfix and enhancement updates issued from time to time, between the regular update sets for point releases. The packages released this way serve as close candidates for the inclusion into the next point release. This repository does not provide security updates, and does not contain packages unsuitable for uncertain inclusion into point releases.[176][177][179]
      CR (Continuous Release)
      makes generally available packages that will appear in the next point release of CentOS. The packages are made available on a testing and hotfix basis, until the actual point release is formally released in form of ISO images.[180]
      debuginfo
      contains packages with debugging symbols generated when the primary packages were built
      contrib
      contains packages contributed by CentOS users that do not overlap with any of the core distribution packages
      Software Collections
      provides versions of software newer than those provided by the base distribution, see above for more details

      By default, CentOS 7 uses an old version of kernel, which is 3.10.x. But the old kernel doesn’t support some new hardwares that we have today. So it’s necessary to update the old kernel for better hardware support. In this article I will show you how to update the kernel of CentOS 7. Let’s get started.

      Preparing for the Kernel Upgrade:

      We must add ELRepo repository to CentOS 7 to update the kernel of CentOS 7. For more information, check the official website of ELRepo at http://elrepo.org/tiki/tiki-index.php. First we have to add the GPG key for ELRepo. To do that, run the following command:

      Now we can add the ELRepo repository on CentOS 7. To do that, run the following command:

      The name of the ELRepo kernel repository is called elrepo-kernel. There are 2 kernels in ELRepo. One is called kernel-lt and the other is called kernel-ml. The difference between these 2 are, kernel-lt package provides the Long Term Support version of the latest Linux kernel, and the kernel-ml package provides Mainline Stable version of the latest Linux kernel. The kernel provided by kernel-ml is more updated than kernel-lt. Both of these kernels are safe. You can use any of them.

      I will show you how to install both of them, but I will install kernel-ml in this article.

      You can check the version of the currently installed kernel on CentOS 7 with the following command:

      You can see that; the kernel CentOS 7 is using right now is 3.10.0. We will soon update that. Let’s continue.

      Installing Latest Long Term Support Kernel:

      You can easily install long term support kernel or kernel-lt package provided by ELRepo on CentOS 7. At the time of this writing, the version of the kernel provided by kernel-lt package is 4.4.100.

      To install kernel-lt package on CentOS 7 from ELRepo, run the following command:

      Press ‘y’ and press <Enter> to continue.

      Installing Mainline Stable Kernel:

      You can easily install mainline stable kernel or kernel-ml package provided by ELRepo on CentOS 7. At the time of this writing, the version of the kernel provided by kernel-ml package is 4.14.1.

      To install kernel-ml package on CentOS 7 from ELRepo, run the following command:

      Centos 7 Latest Kernel Version


      Now press ‘y’ and then press <Enter> to continue:

      It should take a while to download and install the kernel. Once the installation is complete, run the following command to restart your computer.

      Centos 7 Kernel Version

      Centos 7 Kernel Version Update

      Once your computer boots, select the new kernel from the GRUB menu, it should be using the latest kernel that you just installed.

      Centos 7 Latest Kernel Version

      You can check and verify that its using the latest kernel with the following command:

      You can see that the kernel is updated.

      So That’s how you update/upgrade the kernel of your CentOS 7 operating system. Thanks for reading this article.
