本文提供了一套详细的步骤来指导如何从源代码编译并安装Linux内核2.6.24版本，包括下载内核源码、配置内核选项、编译内核、安装新内核及更新grub启动菜单等关键环节。

1,wget -c http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.24.4.tar.bz2
2, make mrproper

3, cp /boot/config* .config ； make oldconfig

or make defconfig [ use the sample config as the .config file (linux-2.6.24.4/arch/x86/configs/i386_defconfig)]

或者更好的使用命令make localmodconfig来产生配置

4, make dep
5, Make kernel and install

make -j4 bzImage V=1
make -j4 modules V=1 
make modules_install V=1

6, install others

cp arch/x86/boot/bzImage       /boo/bzImage-2.6.24
   cp System.map         /boo/System.map-2.6.24 
   mkinitrd -v /boot/initrd-2.6.24.img  2.6.24.4

7, Add strings below to grub/menu.lst

title CentOS (2.6.24)
        root (hd0,0)
        kernel /bzImage-2.6.24 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
        initrd /initrd-2.6.24.img

8,reboot and select your new kernel

9,有可能需要编辑initrd文件
解压:

#  zcat initrd.gz | cpio -ivd --no-absolute-filenames
  打包:
# find . | cpio -o -H newc -F tmp_initrd2
# gzip -f9 tmp_initrd2

10, 查看帮组

[root@Tony32 linux-2.6.39]# make help

11，配置工具比较：

Command	Description
make config	Text based configuration. The options are prompted one after another. All options need to be answered, and out-of-order access to former options is not possible.
make menuconfig	An ncurses-based graphical menu (only text input). Navigate through the menu to modify the desired options.
make defconfig	Generates a new config with default from the ARCH supplied defconfig file. Use this option to get back the default configuration file that came with the sources.
make nconfig	Graphical menu based on ncurses. Requires sys-libs/ncurses to be installed.
make xconfig	Graphical menu using Qt4. Requires dev-qt/qtgui to be installed.
make gconfig	Graphical menu using GTK+. Requires x11-libs/gtk+, dev-libs/glib, and gnome-base/libglade to be installed.
make oldconfig	Review changes between kernel versions and update to create a new .config for the kernel.
make allyesconfig	Enables all configuration options in the kernel. target will set all kernel options to `*`. Make sure a backup of the current kernel configuration is acquired before experimentally using it!

12，编译所有的模块allyesconfig

make mrproper
make allyesconfig
make localmodconfig
make
make modules_install
make install
#重新生成一遍initrd
<pre name="code" class="plain">mkinitrd -v /boot/initrd-2.6.24.img  2.6.24.4
