CentOS7更新内核

内核下载地址：https://elrepo.org/linux/kernel/el7/x86_64/RPMS/

内核包有两种，ml主流，lt长期支持。

我们升级核心肯定是为了主流的功能，lt还升它做甚。

rpm -ivh https://elrepo.org/linux/kernel/el7/x86_64/RPMS/kernel-ml-6.1.0-1.el7.elrepo.x86_64.rpm

#查看可用内核

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

#初始化第一个为默认内核

grub2-set-default 0

#重新创建内核配置

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

#后续有需要再装，不需要搞开发就别装！

#更新kernel-ml-headers
rpm -ivh https://elrepo.org/linux/kernel/el7/x86_64/RPMS/kernel-ml-headers-6.1.0-1.el7.elrepo.x86_64.rpm

#更新kernel-ml-devel
rpm -ivh https://elrepo.org/linux/kernel/el7/x86_64/RPMS/kernel-ml-devel-6.1.0-1.el7.elrepo.x86_64.rpm
