Centos 源码编译指定版本内核

# 下载目标内核源。例如:
wget https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.14.49.tar.xz
tar -xf linux-4.14.49.tar.xz
cd linux-4.14.49

# 应用补丁 （https://github.com/wavezhang/k8s-ipvs-toa）
patch -p1 < ../k8s-ipvs-toa/k8s-ipvs.patch

# 踩了很多坑，需要安装很多工具
yum groupinstall "Development Tools" -y

yum install openssl patch gcc automake autoconf libtool make \
 zlib-devel elfutils elfutils-libelf-devel -y
 
yum install epel-release -y
yum install openssl-devel bc -y
yum install ncurses-devel ntpdate -y 
 
 
cp /boot/config-3.10.0-229.el7.x86_64 .config

sh -c 'yes "" | make oldconfig'

make -j30 bzImage

make -j30 modules

make -j30 modules_install

make install


# 查看插入顺序，看一下
cat /boot/grub2/grub.cfg |grep "menuentry "
awk -F\' '$1=="menuentry " {print $2}' /etc/grub2.cfg

# 修改启动顺序
grub2-set-default 'CentOS Linux (4.14.49) 7 (Core)'

# 查看启动顺序
grub2-editenv list

# 重启生效
reboot
