    How do I upgrade my Linux kernel? I would like to upgrade kernel without compiling from source code i.e. binary upgrade. How do I perform the actual upgrade of the kernel in Linux?

    You need to compile kernel only if:
    => You need custom made kernel for specific task such as embedded kernel.
    => Apply third party security patches.
    => You need to apply specific patch to Linux

    Upgrade of the kernel in Red Hat enterprise Linux version <= 4.x

    If your system is registered with Red Hat Network (RHN), then you can use the up2date command as follows:
    # up2date -f kernel
    For SMP kernel (multi core or multiple CPU) use command:
    # up2date -f kernel-smp

    Upgrade of the kernel in Fedora Linux / CentOS / RHEL 5

    Use yum command to upgrade kernel:
    # yum update kernel
    If you have downloaded RPM file use rpm command:
    # rpm -ivh kernel*

    Upgrade of the kernel in Debian or Ubuntu Linux

    Use apt-get command. First find your kernel version:
    $ uname -r
    Next find available kernel images:
    $ apt-cache search linux-image
    Now install kernel by explicitly specifying version number:
    # apt-get install linux-image-x.x.x-xx
    OR
    $ sudo apt-get install linux-image-x.x.x-xx
