ubuntu nfs配置 以及mount.nfs:access denied by server while mounting問題解決

1.安裝nfs服務，$ apt-get install nfs-common 

  nfs-kernel-server
2.配置參數：$ gedit  /etc/exports ,內容如下：
   # /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/ygp/nfs *(rw,sync,no_root_squash)      ＃該目錄為nfs服務根目錄

3.測試
   mount  -t nfs localhost:/home/ygp/nfs  /mnt
   cd /mnt  可以看到已經共享/home/ygp/nfs的內容了。
　showmount -e......

 

問題解決：

環境 ubuntu 10.4   vm 7.1
終端
ifconfig 得到 ubuntu資料
INET ADDR 192.168.0.4
BCAST   192.168.0.255
MASK 255.255.255.0

一 安裝NFS
$ sudo apt-get install nfs-kernel-server
$ sudo apt-get install nfs-common

二 配置NFS
1 $ sudo dpkg-reconfigure portmap , 對Should portmap be bound to the loopback address? 選N
2 $ sudo   /etc/default/portmap 末行清除 "-i 127.0.0.1"

三 配置hosts.deny
$ sudo vi   /etc/hosts.deny
文本末添加
### NFS DAEMONS
   portmap: ALL
   lockd:     ALL
   mountd:   ALL
   rquotad: ALL
   statd:     ALL

四 配置hosts.allow
   $ sudo vi /etc/hosts.allow
文本末加入
### NFS DAEMONS
   portmap: 192.168.0.
   lockd:     192.168.0.
   rquotad: 192.168.0.
   mountd:   192.168.0.
   statd:      192.168.0.
$ sudo /etc/init.d/portmap restart 重啟portmap daemon.
顯示如下
Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the restart(8) utility, e.g. restart portmap
portmap start/running, process   XXXX

五 配置/etc/exports
$ sudo vi /etc/exports
文本末添加
/home/work *(rw,sync,no_root_squash)
chmod 777 -R /home/work
$ sudo showmount -e
顯示 clnt-create : RPC : Program not registered

$ sudo   exportfs -r 更新

$ sudo   showmount 192.168.0.4 -e
顯示
Export list for 192.168.0.4:
/home/work *

六 啟用
   $ sudo /etc/init.d/nfs-kernel-server restart 重啟nfs服務
顯示如下
* Stopping NFS kernel daemon                                                      [ OK ]
* Unexporting directories for NFS kernel daemon...                   [ OK ]
* Exporting directories for NFS kernel daemon...                           
   exportfs: /etc/exports [1]: Neither 'subtree_check' or 'no_subtree_check' specified for export "*:/home/work".
   Assuming default behaviour ('no_subtree_check').
   NOTE: this default has changed since nfs-utils version 1.0.x
                                                                        

* Starting NFS kernel daemon                                                          [ OK ]
