RHEL/Rocky Linux/AlmaLinux 8和9删除旧版本内核方法

RHEL/Rocky Linux/AlmaLinux 8和9删除旧版本内核方法
最近在云服务器上安装了Rocky Linux 9.4，RHEL系最新小版本是9.7，所以就执行了一下升级(dnf -y upgrade)。然而默认更新升级操作都不会清理旧版本的内核。在云服务器上啥资源都是钱，所以能优化就优化，蚊子腿也是肉。

1、查看当前内核版本

uname -a

2、查看已安装的所有内核

rpm -qa | grep kernel

3、删除旧内核(确认系统和应用无兼容性问题后执行)

dnf -y remove kernel-core-5.14.0-570.58.1.el9_6.x86_64

4、清理不再需要的依赖包

dnf autoremove

5、清理残留目录和文件

删除/lib/modules/目录下对应内核版本的目录和文件
