How to build Linux Kernel ...

跟著下面的步驟就可以輕鬆的將linux kernel給build出來啦 ~

1. 安裝SRPM, kernel-.sec.rpm以及產生kernel source

# yum install fedora-rpmdevtools
# fedora-buildrpmtree
# yum install yum-utils
# yumdownloader --source kernel
# rpm -ivh kernel-.src.rpm
# cd /rpmbuild
# rpmbuild -bp --target $(uname -m) kernel-2.6.spec

2. 更改kernel的版本

# cd /rpmbuild/BUILD/kernel-/linux-
# vi Makefile
    ...
    EXTRAVERSION = XXX (改成自己能識別的名稱)
    ...

3. 清除config file以及用預設的config file

# make mrproper
# cp /boot/config- .config
# make oldconfig
# make clean

4. 建立新的kernel與安裝kernel

# make bzImage modules modules_install
# make install

5. 將新的kernel設為預設的開機kernel

# vi /boot/grub/grub.conf
    ...
    default=0
    ...

6. 重新開機並確認版本

# reboot
# uname -a
