Installing New Kernel

1. You will be given the ftp URL where the kernel is available.
2. Open that URL in different tab
3. Note down your current kernel name in PAPER (#uname -r)
4. Download all the kernel files(kernel-*) using #wget from the given URL i.e. opened in different tab of base m/c
5. Note: Ideally 2 files will be there inside the kernel directory of the given URL: eg
6. 1: kernel-<version>.rpm
7. 2: kernel-firmware-<version>.rpm
8. write down the new kernel version which is going to be installed in the PAPER
9. It will be downloaded into the current directory
10. Install it using #rpm
11. #rpm -ivh kernrl-* --force     --->may take 2-3 mins to install
12. Check in file
13. #vim /boot/grub/grub.conf
14. <you will see 2 kernels in the kernel/Title section, old & new. For the system to install with new kernel, defaults=0 (zero) , so first one should be the new kernel which is required>
15. #reboot
16. To verify press esc and verify your kernel name which is going to boot.
17. After booting is done, verify the new kernel (#uname -r)

Configure variable=value(sysvctl=1) in kernel Parameter

In exam question would be asked to ensure sysvctl=1 is available as a kernel parameter and it should reflect in /proc/cmdline

Make the corresponding changes in
#vim /boot/grub/grub.conf
<update the required thing eg . sysvctl=1 at the end of kernel section,>
save & quit
Note: This question will come after installing the new kernel question
