Recently, I am going to install K8s on Centos. I feel that the kernel version needs to be high, so upgrade!

1. Backup grub.cfg

Cp / boot/grub2/grub.cfg / boot/grub2/grub.cfg_bak

two,

Sed-I 's/rhgb quiet/quiet/g' / boot/grub2/grub.cfg

three,

Rpm-ivh kernel-ml-4.19.9-1.el7.elrepo.x8664.rpm

four,

Cat / boot/grub2/grub.cfg | grep menuentry

Grub2-set-default "CentOS Linux (4.19.9-1.el7.elrepo.x86_64) 7 (Core)"

Grub2-editenv list

Yum-y install perl

Rpm-ivh kernel-ml-devel-4.19.8-1.el7.elrepo.x8664.rpm

Remarks: these two kernel files are saved in my Aliyun warehouse.
