mount.nfs：在 Ubuntu 机器上安装时服务器拒绝访问？

我有三台机器 -

machineA    10.108.24.132
machineB    10.108.24.133
machineC    10.108.24.134

所有这些机器都安装了 Ubuntu 12.04，并且我对这三台机器都有 root 访问权限。

现在我应该在上面的机器上做以下事情 -

Create mount point /opt/exhibitor/conf
Mount the directory in all servers.
 sudo mount <NFS-SERVER>:/opt/exhibitor/conf /opt/exhibitor/conf/

我已经/opt/exhibitor/conf在上述所有三台机器上创建了目录。

现在我尝试在这三台机器上创建一个挂载点。因此我遵循了以下步骤 -

安装NFS 支持文件和NFS 内核服务器

$ sudo apt-get install nfs-common nfs-kernel-server

创建共享目录

$ mkdir /opt/exhibitor/conf/

编辑 /etc/exports 并添加如下条目：

# /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)
#
/opt/exhibitor/conf/     10.108.24.*(rw)

运行 exportfs

root@machineA:/# exportfs -rv
exportfs: /etc/exports [1]: Neither 'subtree_check' or 'no_subtree_check' specified for export "10.108.24.*:/opt/exhibitor/conf/".
  Assuming default behaviour ('no_subtree_check').
  NOTE: this default has changed since nfs-utils version 1.0.x

exporting 10.108.24.*:/opt/exhibitor/conf

现在我做showmount了machineA

root@machineA:/# showmount -e 10.108.24.132
Export list for 10.108.24.132:
/opt/exhibitor/conf 10.108.24.*

现在当我这样做时，我收到了一个错误 -

root@machineA:/# sudo mount -t nfs 10.108.24.132:/opt/exhibitor/conf /opt/exhibitor/conf/
mount.nfs: access denied by server while mounting 10.108.24.132:/opt/exhibitor/conf

知道我在这里做错了什么吗？

答案1

更改你的 /etc/exports

/opt/exhibitor/conf/     10.108.24.*(rw)

到

/opt/exhibitor/conf/     10.108.24.0/24(rw)

答案2

似乎您正在尝试在同一台服务器上执行 NFS 挂载

root@machineA:/# sudo mount -t nfs 10.108.24.132:/opt/exhibitor/conf /opt/exhibitor/conf/

机器A是10.108.24.132

你试过了吗？

root@machineB:/# mkdir -p /opt/exhibitor/conf
root@machineB:/# sudo mount -t nfs 10.108.24.132:/opt/exhibitor/conf /opt/exhibitor/conf/

在机器C上

root@machineC:/# mkdir -p /opt/exhibitor/conf
root@machineC:/# sudo mount -t nfs 10.108.24.132:/opt/exhibitor/conf /opt/exhibitor/conf/

您应该能够从 machineA 执行此操作，但使用不同的目录作为挂载点：

root@machineA:/# mkdir -p /opt/exhibitor/conf2
root@machineA:/# sudo mount -t nfs 10.108.24.132:/opt/exhibitor/conf /opt/exhibitor/conf2/

答案3

在此之前，我很抱歉我的英语很糟糕。但我会尽力写得更好。

我认为您需要在安装时设置用户名和密码。

mount -t nfs 10.108.24.132:/opt/exhibitor/conf /opt/exhibitor/conf/ -o username=USERNAME,password=PASSWORD

我从未尝试过 nfs，我的机器上使用 samba。在 samba 中，我们需要将 linux 用户添加到 samba 用户。

smbpasswd -a username

也许在 nfs 中也是同样的情况。
