ubuntu nfs

NFS是Net File System的簡寫,即網絡文件系統.
網絡文件系統是FreeBSD支持的文件系統中的一種，也被稱爲NFS. NFS允許一個系統在網絡上與它人共享目錄和文件。通過使用NFS，用戶和程序可以象訪問本地文件一樣訪問遠端系統上的文件。

我的系統爲ubuntu9.04，配置NFS時遇到了些問題，不過最後還是解決了。謝謝hi.baidu.com/leoxeon/blog/item/e59d4644fc8e8e48500ffe4e.html的文章幫我解決了最後的一個錯誤。

安裝nfs-kernerl-server
creek@creek-laptop:~$ sudo apt-get install nfs-kernel-server這時順帶着也會安裝上nfs-common
添加共享目錄
creek@creek-laptop:~$ sudo gedit /etc/exports
在其中添加如下行：
/home/creek/nfs       *(rw,sync,no_subtree_check)
在我的用戶目錄下創建目錄
creek@creek-laptop:~$mkdir nfs
修改操作權限
creek@creek-laptop:~$chmod 777 -R nfs
然後按照查到的資料上輸入以下命令
creek@creek-laptop:/etc$ init.d/nfs-kernel-server start
* Exporting directories for NFS kernel daemon...                              
exportfs: could not open /var/lib/nfs/etab for locking
exportfs: can't lock /var/lib/nfs/etab for writing
[ OK ]
* Starting NFS kernel daemon                                            [fail]
按照提示修改 /var/lib/nfs/etab權限
creek@creek-laptop:~$chmod 777 -R /var/lib/nfs/etab
再試
creek@creek-laptop:/etc$ init.d/nfs-kernel-server start
* Exporting directories for NFS kernel daemon...                              
exportfs: can't open /var/lib/nfs/etab.tmp for writing
[ OK ]
* Starting NFS kernel daemon                                            [fail]
發現沒有/var/lib/nfs/etab.tmp這個文件，而且/var/lib/nfs對非創建用戶是不可寫的，於是
creek@creek-laptop:~$chmod 777 -R /var/lib/nfs
又試
creek@creek-laptop:/etc$ init.d/nfs-kernel-server start
* Exporting directories for NFS kernel daemon...                        [ OK ]
* Starting NFS kernel daemon                                            [fail]
沒有提示錯誤了，可是依舊不能啓動NFS服務，restart nfs 得到這樣的結果
creek@creek-laptop:/etc$ init.d/nfs-kernel-server restart
* Stopping NFS kernel daemon                                            [ OK ]
* Unexporting directories for NFS kernel daemon...                      [ OK ]
* Exporting directories for NFS kernel daemon...                        [ OK ]
* Starting NFS kernel daemon                                            [fail]
後來在上面的博客中找到答案
creek@creek-laptop:~$ sudo /etc/init.d/portmap start
* Starting portmap daemon...                                                   
* Already running.                                                      [ OK ]
creek@creek-laptop:~$ sudo /etc/init.d/nfs-common start
* Starting NFS common utilities                                         [ OK ]
creek@creek-laptop:~$ sudo /etc/init.d/nfs-kernel-server start
* Exporting directories for NFS kernel daemon...                        [ OK ]
* Starting NFS kernel daemon                                            [ OK ]
最後NFS成功啓動。
