uname -r
2.6.32-358.el6.i686
2、下载src.rpm包
http://vault.centos.org/6.4/os/Source/SPackages/kernel-2.6.32-358.el6.src.rpm
3、普通用户执行：
mkdir -p ~/rpmbuild/{BUILD,BUILDROOT,RPMS,SOURCES,SPECS,SRPMS}
echo '%_topdir %(echo $HOME)/rpmbuild' > ~/.rpmmacros
4、root用户执行：
yum install rpm-build redhat-rpm-config asciidoc hmaccalc perl-ExtUtils-Embed xmlto
yum install audit-libs-devel binutils-devel elfutils-devel elfutils-libelf-devel
yum install newt-devel python-devel zlib-devel
5、创建用户mockbuild，因为在第6步rpm安装的时候，需要这个用户
useradd -s /sbin/nologin mockbuild
6、普通用户执行，该执行过程中，需要用到mockbuild用户，否则会出现告警
（warning: group mockbuild does not exist - using root
warning: user mockbuild does not exist - using root）:
具体执行：
[hadoop@hadoop1 ~]$rpm -ivh kernel-2.6.32-358.2.1.e16.src.rpm
[hadoop@hadoop1 ~]$ cd ~/rpmbuild/
[hadoop@hadoop1 rpmbuild]$ cd SPECS/
[hadoop@hadoop1 SPECS]$ ls
kernel.spec
[hadoop@hadoop1 SPECS]$ rpmbuild -bp --target=$(uname -m) kernel.spec

缺少包，root安装：
yum install gcc
yum install patchutils
yum install bison
在yum中，如果遇到：
[root@hadoop1 SPECS]# yum install bison

这个是常规更新程序，直接用kill -9 停掉就可以了。
6、源码位置
