linux内核升级

wget https://dl.lamp.sh/kernel/el7/kernel-ml-5.15.63-1.el7.x86_64.rpm

wget https://dl.lamp.sh/kernel/el7/kernel-ml-devel-5.15.63-1.el7.x86_64.rpm

yum localinstall kernel-ml-*.rpm --skip-broken

awk -F\' '$1=="menuentry " {print i++ " : " $2}' /etc/grub2.cfg

grub2-set-default 0

vim /etc/default/grub

GRUB_DEFAULT=0

grubby --default-kernel

reboot

 

以上是centos7内核从3升级到5的正确升级过程，采用网上的升级过程，无法完成升级
