Refer to FAQ for Changes to Red Hat's Entitlement Platform with RHEL 6.1 and 5.7 and What's the difference between management services provided by Red Hat Network (RHN) Classic and Red Hat Subscription Management (RHSM)? To register your system either trough the GUI or form the command line follow the instructions in the Using and Configuring Red Hat Subscription Manager guide.Make sure that your firewall allows configuring RHSM, for more information see How do I access RHSM (yum) through a firewall? General information on RHSM can be found in Red Hat Network Subscription Management, while FAQ for Changes to Red Hat's Entitlement Platform with RHEL 6.1 and 5.7 provides a quick overview and a comparison with RHN.One important thing to consider is the life cycle of a kernel version – if the version you are currently using is approaching its end of life, no more bug fixes will be provided after that date. Most modern distributions provide a way to upgrade the kernel using a package management system such as yum and an officially-supported repository.However, this will only perform the upgrade to the most recent version available from the distribution’s repositories – not the latest one available in the https://To show the current version installed on our system we can do: If we now go to https:// we will see that the latest kernel version is 4.17 at the time of this writing (other versions are available from the same site).This new Kernel 4.17 version is a long-term release and will be supported for 6 years, earlier all Linux Kernel versions were supported for 2 years only.I need to update the kernel from version 2.6.30 to 2.6.37.
During normal operations, the kernel is responsible for performing two important tasks: To do this, the kernel communicates with the hardware through the drivers that are built into it or those that can be later installed as a module.To enable the ELRepo repository on Cent OS 7, do: GRUB_TIMEOUT=5 GRUB_DEFAULT=0 GRUB_DISABLE_SUBMENU=true GRUB_TERMINAL_OUTPUT="console" GRUB_CMDLINE_LINUX="lv=centos/root lv=centos/swap crashkernel=auto rhgb quiet" GRUB_DISABLE_RECOVERY="true" Congratulations! In this article we have explained how to easily upgrade the Linux kernel on your system.There is yet another method which we haven’t covered as it involves compiling the kernel from source, which would deserve an entire book and is not recommended on production systems.Before installing an update, make sure all previously released errata relevant to the system have been applied.To access updates when using Red Hat Enterprise Linux 7, launch the graphical update tool through Applications - Before installing an update, make sure all previously released errata relevant to the system have been applied.
