将Linux内核安装到指定目录

在编译服务器很多时候没得root权限，linux内核编译后，install 一下，方便得到一套vmlinuz+lib/modules。

#!/bin/bash

if [ ! -f vmlinux ]; then

  echo "need to make all build first"

  exit 0

fi

fakeroot=~/fake

if [ ! -d $fakeroot ]; then

  mkdir -p $fakeroot

fi

INSTALL_MOD_PATH=$fakeroot INSTALL_MOD_STRIP=1 make modules_install

fakeboot=$fakeroot/boot

if [ ! -d fakeboot ]; then

  mkdir -p $fakeboot

fi

INSTALL_MOD_PATH=$fakeroot INSTALL_PATH=$fakeboot make install

echo "======================"

echo "kernel image installed in $fakeboot"

echo "kernel image installed in $fakeroot/lib/modules/"

echo "======================"
