今天突然发现CentOS系统没有nbd模块，只能重新装下，下面记录下整个编译过程：
[[email protected] ~]# yum install -y kernel-headers kernel-devel [[email protected] ~]# wget ftp://ftp.redhat.com/pub/redhat/linux/enterprise/6ComputeNode/en/os/SRPMS/kernel-2.6.32-431.el6.src.rpm [[email protected] ~]# rpm -ivh kernel-2.6.32-431.el6.src.rpm [[email protected] ~]# cd ~/rpmbuild/SOURCES/ [[email protected] SOURCES]# tar jxf linux-2.6.32-431.el6.tar.bz2 -C /usr/src/kernels/ [[email protected] SOURCES]# cd /usr/src/kernels/ [[email protected] kernels]# mv $(uname -r) $(uname -r)-old [[email protected] kernels]# mv linux-2.6.32-431.el6 $(uname -r) [[email protected] kernels]# cd $(uname -r) [[email protected] 2.6.32-431.el6.x86_64]# make mrproper [[email protected] 2.6.32-431.el6.x86_64]# cp ../$(uname -r)-old/Module.symvers .

至此，nbd模块已经成功编译。
下面加载nbd模块并查看成功装载后的情况：
