CentOS6编译装载nbd模块

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:

系统:CentOS6.5

内核:2.6.32-431.el6.x86_64

[root@localhost ~]# yum install -y kernel-headers kernel-devel

[root@localhost ~]# wget ftp://ftp.redhat.com/pub/redhat/linux/enterprise/6ComputeNode/en/os/SRPMS/kernel-2.6.32-431.el6.src.rpm

[root@localhost ~]# rpm -ivh kernel-2.6.32-431.el6.src.rpm

[root@localhost ~]# cd ~/rpmbuild/SOURCES/
[root@localhost SOURCES]# tar jxf linux-2.6.32-431.el6.tar.bz2 -C /usr/src/kernels/ [root@localhost SOURCES]# cd /usr/src/kernels/
[root@localhost kernels]# mv $(uname -r) $(uname -r)-old
[root@localhost kernels]#
mv linux-2.6.32-431.el6 $(uname -r) [root@localhost kernels]# cd $(uname -r)
[root@localhost
2.6.32-431.el6.x86_64]# make mrproper
[root@localhost
2.6.32-431.el6.x86_64]# cp ../$(uname -r)-old/Module.symvers . [root@localhost 2.6.32-431.el6.x86_64]# cp /boot/config-$(uname -r) ./.config
[root@localhost
2.6.32-431.el6.x86_64]# make oldconfig
[root@localhost
2.6.32-431.el6.x86_64]# make prepare
[root@localhost
2.6.32-431.el6.x86_64]# make scripts
[root@localhost
2.6.32-431.el6.x86_64]# make CONFIG_BLK_DEV_NBD=m M=drivers/block [root@localhost 2.6.32-431.el6.x86_64]# cp drivers/block/nbd.ko /lib/modules/$(uname -r)/kernel/drivers/block/
[root@localhost 2.6.32-431.el6.x86_64]# depmod -a

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:

[root@localhost image]# modprobe nbd max_part=8
[root@localhost image]# ll /dev/nbd*
