1- To begin create new file “noyau.repo” and save it :
vim /etc/yum.repos.d/noyau.repo [updates] name=RedHat updates baseurl=ftp://Server/ftp/updates enabled=1 gpgcheck=0 :wq
2- Now, Juste tape this command To force the update :
yum update kernel
And It’s DONE !
Note:
If you want to keep the old kernel as the default kernel bootable by grub, you have to execute this command :
grub2-set-default 1
Cause, by default the new kernel is used after reboot :
systemctl reboot
