If kernel-ml appears in the list, then it succeeded.
[root@iZbp141m9g3iwgwsmh7pvzZ ]# yum --enablerepo=elrepo install -y kernel-ml
kernel-ml provides the latest kernel features, hardware support and performance optimizations for users who need the latest technology or hardware. It also contains the latest security fixes, but stability should be carefully evaluated for use in production environments.
Configure the kernel you just downloaded as a self-starting kernel
vim /etc/default/grub
# Open and edit /etc/default/grub and set GRUB_DEFAULT=0.
grub2-mkconfig -o /boot/grub2/
Check if the kernel was successfully updated
