linux下配置nfs错误

我在linux配置nfs服务 gedit /etc/exports内容 /home/wang/Music *(rw)
mount -t nfs localhost: /home/wang/Music /mnt/ 时，打印以下问题[root@localhost wang]# mount -t nfs localhost: /home/wang/Music /mnt/c
Usage: mount -V : print version
mount -h : print this help
mount : list mounted filesystems
mount -l : idem, including volume labels
So far the informational part. Next the mounting.
The command is `mount [-t fstype] something somewhere'.
Details found in /etc/fstab may be omitted.
mount -a [-t|-O] ... : mount all stuff from /etc/fstab
mount device : mount device at the known place
mount directory : mount known device here
mount -t type dev dir : ordinary mount command
Note that one does not really mount a device, one mounts
a filesystem (of the given type) found on the device.
One can also mount an already visible directory tree elsewhere:
mount --bind olddir newdir
or move a subtree:
mount --move olddir newdir
One can change the type of mount containing the directory dir:
mount --make-shared dir
mount --make-slave dir
mount --make-private dir
mount --make-unbindable dir
One can change the type of all the mounts in a mount subtree
containing the directory dir:
mount --make-rshared dir
mount --make-rslave dir
mount --make-rprivate dir
mount --make-runbindable dir
A device can be given by name, say /dev/hda1 or /dev/cdrom,
or by label, using -L label or by uuid, using -U uuid .
Other options: [-nfFrsvw] [-o options] [-p passwdfd].
For many more details, say man 8 mount .
不知怎么解决，求高手指点。

Answer 1

看你输入的命令好像有点问题：localhost:后面应该是没有空格的。再试试把localhost改成IP地址

Answer 2

如果不是时间特别充足，最好别排错啦，因为配置文件有可能就是多了个空格的事就不能正常启动服务，你最好重要的配置备份下，然后将原软件卸载，再重新安装。还有你应该是学生吧，这个应该是你做实验吧，现实生活中很少用nfs的，都用samba

Answer 3

看看防火墙。把防火墙关了。

Answer 4

showmount -e IP 先看一下。
