CentOS内核源码的安装方法

不完整的内核源码：

安装：
     * kernel-devel (both 32- & 64-bit architectures)
     * kernel-xen-devel (both 32- & 64-bit architectures)
     * kernel-PAE-devel (32-bit architecture only)
执行：
ln -s /usr/src/kernels/2.6.18-238.19.1.el5xen-x86_64  /lib/modules/$(uname -r)/build

完整的内核源码：

yum install rpm-build redhat-rpm-config unifdef

wget http://vault.centos.org/5.7/updates/SRPMS/kernel-2.6.18-274.7.1.el5.src.rpm

rpm -Uvh kernel-2.6.18-274.7.1.el5.src.rpm

cd /usr/src/redhat/SPECS
rpmbuild -bp --target=`uname -m` kernel.spec

最终源码在/usr/src/redhat/build目录中：/usr/src/redhat/BUILD/kernel-2.6.18/linux-2.6.18-274.7.1.el5.x86_64/
