解决Linux挂载nfs时出现Operation not supported

[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)
