#安装内核
rpm -ivh kernel-lt-5.4.225-1.el7.elrepo.x86_64.rpm
rpm -ivh kernel-lt-devel-5.4.225-1.el7.elrepo.x86_64.rpm
确认已安装内核版本
rpm -qa | grep kernel
查看系统上的所有可用内核
sudo awk -F\' '1=="menuentry " {print i++ " : " 2}' /etc/grub2.cfg
grub2-set-default 0
生成grub配置文件
grub2-mkconfig -o /boot/grub2/grub.cfg
重启
reboot
验证升级是否成功
uname -a
仅查看版本信息
uname -r
通过绝对路径查看查看版本信息及相关内容
cat /proc/version
通过绝对路径查看查看版本信息
cat /etc/redhat-release
删除旧内核
rpm -qa | grep kernel
