一、参考文档：
1. linux基础——在redhat6下配置yum源的使用
http://blog.itpub.net/23890223/viewspace-757724/
2. redhat6.8 download:
ftp://ftp.redhat.com/pub/redhat/linux/enterprise/6Server/en/os/SRPMS/
3. Index of /centos/6/os/i386/Packages/
http://mirrors.163.com/centos/6/os/i386/Packages/
4. RHEL6编译升级官方内核
http://blog.csdn.net/sailor201211/article/details/53747642
5. 安装RPM套件rpm-build错误解决：NOKEY、elfutils is needed

二、下载内核
ftp://ftp.redhat.com/pub/redhat/linux/enterprise/6Server/en/os/SRPMS/
三、操作流程：

[root@localhost ~]# cd /root/rpmbuild/SPECS
[root@localhost SPECS]# rpmbuild -bp --with fireware --target=`uname -m` kernel.spec
