编译内核的一般步骤
1、下载内核源码 www.kernel.org
2、解压内核文件到指定目录， /usr/src
3、选择所需功能 make menuconfig
4、选择完成后进行编译 make
5、安装模块 make modules_install
6、安装内核 make install
# 解压软件包，并移动到/usr/src下，制作一个软连接
[root@localhost ~]# tar xf linux-2.6.29.tar.bz2 -C /usr/src/
[root@localhost ~]# cd /usr/src/
[root@localhost src]# ln -s linux-2.6.29 linux
[root@localhost src]#
# 为了选择方便，复制系统上的内核配置文件，到新版本的源码目录下
# 并重命名为.config
[root@localhost ~]# cd /usr/src/linux
[root@localhost linux]# cp /boot/config-2.6.18-308.el5 ./.config
[root@localhost linux]#
[root@localhost linux]# make menuconfig
