[root@HOSTNAME:tmp]#mount -t nfs -o nolock 192.168.0.15:/home/ubuntu/rootfs /mnt
mount: mounting 192.168.0.15:/home/ubuntu/rootfs on /mnt failed: Operation not supported

解决办法:
在nfs服务器/etc/exports文件中添加insecure选项

ubuntu@system:~/Desktop/unix$ cat /etc/exports 
# /etc/exports: the access control list for filesystems which may be exported
#		to NFS clients.  See exports(5).
#
# Example for NFSv2 and NFSv3:
# /srv/homes       hostname1(rw,sync,no_subtree_check) hostname2(ro,sync,no_subtree_check)
#
# Example for NFSv4:
# /srv/nfs4        gss/krb5i(rw,sync,fsid=0,crossmnt,no_subtree_check)
# /srv/nfs4/homes  gss/krb5i(rw,sync,no_subtree_check)
#
/home/ubuntu/rootfs *(rw,sync,insecure,no_root_squash)

还少一个参数,就是挂载到什么地方。
加上试一试

可以了!
使用

mount -t nfs 192.168.0.15:/home/ubuntu/rootfs /mnt

会出现卡死的情况
然后使用

mount -t nfs -o nolock 192.168.0.15:/home/ubuntu/rootfs /mnt

就OK:D=D

晕哥 说:

期待好消息!

应该是我的文件系统制作的有些问题,进入Linux直接挂载出现

[root@HOSTNAME:]#mount -t nfs 192.168.0.15:/home/ubuntu/rootfs
mount: can't read '/etc/fstab': No such file or directory

晕哥 说:

如果按上面步骤可以,说明你的网卡驱动,nfs文件系统,网卡硬件,有线网络,nfs服务器均正常。
如果不这么做,任何一个环节有问题都可能出现不能进入系统。

好!谢谢您!我将文件系统烧进入试试:D
