CentOS使用yum的elrepo源升级内核

  

 

1、 导入public key

Import the public key:

2、查看kernel

yum --enablerepo=elrepo-kernel  list  |grep kernel*

安装kernel-ml(ml=mainline)

yum --enablerepo=elrepo-kernel install kernel-ml -y

3、 更改/etc/default/grub

 

 4、更新grub.conf

grub2-mkconfig -o /boot/grub2/grub.cfg

5、 重启shutdown -r now
