mount.nfs：在 Ubuntu 電腦中安裝時伺服器拒絕存取？

mount.nfs：在 Ubuntu 電腦中安裝時伺服器拒絕存取？

我有三台機器 -

machineA    10.108.24.132
machineB    10.108.24.133
machineC    10.108.24.134

所有這些機器都安裝了 Ubuntu 12.04，並且我對這三台機器都有 root 存取權。

現在我應該在我的上面的機器上做以下事情 -

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

/opt/exhibitor/conf如上所述，我已經在所有這三台機器中建立了目錄。

現在我試圖在所有這三台機器上建立一個掛載點。所以我遵循了以下過程 -

安裝 NFS 支援檔案和 NFS 核心伺服器

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

建立共享目錄

$ mkdir /opt/exhibitor/conf/

編輯 /etc/exports 並新增以下條目：

# /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)

運行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

現在我做showmount了machineA

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

現在當我這樣做時，我收到一個錯誤 -

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

知道我在這裡做錯了什麼嗎？

答案1

更改您的 /etc/exports

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

到

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

答案2

看起來您正在嘗試在同一台伺服器上進行 NFS 掛載

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

機器A是10.108.24.132

你試過了嗎？

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

在機器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/

您應該能夠從 machineA 執行 if 但使用不同的目錄作為安裝點：

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

之前，我很抱歉我的英語很糟糕。但我會盡力寫得更好。

我認為您需要在安裝時設定使用者名稱和密碼。

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

我從來沒有嘗試過 nfs，我在我的機器上使用 samba。在samba中，我們需要將linux用戶加入samba用戶。

smbpasswd -a username

也許nfs中也是同樣的情況。
