OpenEuler2203编译打包升级高版本kernel6.6版本内核

一，使用以下方法，编译官方提供的内核版本。

git clone https://gitee.com/openeuler/kernel.git
cd kernel/
git checkout OLK-6.6
make  openeuler_defconfig
make  -j4
yum install elfutils-libelf-devel dwarves openssl-devel rsync -y
make binrpm-pkg -j64
cd kernel
rpm -ivh ./rpmbuild/RPMS/x86_64/kernel-6.6.0+-2.x86_64.rpm
yum install ./rpmbuild/RPMS/x86_64/kernel-headers-6.6.0+-2.x86_64.rpm

二，kernel内核官网最新版6.6.40编译方法

 1，下载对应版本的内核源码包并解压

wget https://mirrors.edge.kernel.org/pub/linux/kernel/v6.x/linux-6.6.40.tar.gz

tar -zxvf linux-6.6.40.tar.gz -C /usr/src/

2，下载openeuler官网内核源码打包文件

这里主要是借用内核编译配置文件，这样就不用编译时作选择了。

wget https://mirror.nju.edu.cn/openeuler/openEuler-24.03-LTS/everything/x86_64/Packages/kernel-source-6.6.0-28.0.0.34.oe2403.x86_64.rpm

rpm -ivh kernel-source-6.6.0-28.0.0.34.oe2403.x86_64.rpm

3，安装依赖包

yum -y install elfutils-libelf-devel dwarves openssl-devel rsync

4，编译内核

   cd /usr/src/

   cp /usr/src/linux-6.6.0-28.0.0.34.oe2403.x86_64/arch/x86/configs/openeuler_defconfig  /usr/src/linux-6.6.40/arch/x86/configs/
   make  openeuler_defconfig
   make  -j4

5，打包内核RPM包

  make binrpm-pkg -j64

6，安装RPM包

   rpm -ivh ./rpmbuild/RPMS/x86_64/kernel-6.6.40-2.x86_64.rpm 
   rpm -ivh ./rpmbuild/RPMS/x86_64/kernel-headers-6.6.40-2.x86_64.rpm 
   或是
  rpm -Uvh ./rpmbuild/RPMS/x86_64/ kernel-headers-6.6.40-2.x86_64.rpm 

7，修改启动项

grub2-set-default 0

8，重启系统，查看内核信息
