mount.nfs: access denied by server while mounting localhost:/home/xuwq/minilinux/system

在执行命令如下:

mount -t nfs localhost:/home/xuwq/minilinux/system /mnt

出现的错误:

mount.nfs: access denied by server while mounting localhost:/home/xuwq/minilinux/system

用以下的命令查看了日志,结果如下:

root@xuwq:/var/log# cat /var/log/syslog | grep mount

通过日志可以看出是因为/home/xuwq/minilinux/system目录没有被共享,通过对比/etc/export文件找出了原因,原来是/etc/export文件中的共享目录输入错误。

错误的/etc/exports文件内容:

# /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_subt
ree_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)
#

<span style="color:#FF0000;">/home/xuwq/minilinux/*(rw,sync,no_root_sqush)</span>

正确的/etc/exports文件:

# /etc/exports: the access control list for filesystems which may be exported
#               to NFS clients.  See exports(5).
#
# Example for NFSv2 and NFSv3:

#

<span style="color:#FF0000;">/home/xuwq/minilinux/system/*(rw,sync,no_root_sqush)</span>

红色字体的为我的 共享目录。

重启nfs服务后再次执行如下命令,挂在成功:

mount -t nfs localhost:/home/xuwq/minilinux/system /mnt

使用df命令可以看到已挂在成功:

root@xuwq:/var/log# df
