========================================================================
在 solaris 中,並不像其它的 UNIX 系統一樣,要利用 NFS 來 export硬碟是去修
改 /etc/exports. 而是要去修改 /etc/dfs/dfstab 這個檔. 設定的方法如下:

利用 share 來 export 硬碟,share 的參數如下:

Attrib         Description
===============================================
-ro          Export read-only, or of used in the form -ro=list, restrict
             access only for the listed hosts.
-rw          Export read-write, or if used in the form -rw=list, allow
             writing only by the listed hosts.
-root=list   Lists hosts permitted to access this filesystem as root. Other-
             wise, root access from a client is equivalent to access by the
             user nobody (usually UID -2).
-anon=n      Specifies UID used for requests coming from an unknown user.
             If not specified, defaults to nobody.

以下舉一個例子,說明 /etc/dfs/dfstab 的寫法.

#       Place share(1M) commands here for automatic execution
#       on entering init state 3.
#
#       Issue the command '/etc/init.d/nfs.server start' to run the NFS
#       daemon processes and the share commands, after adding the very
#       first entry to this file.
#
#       share [-F fstype] [ -o options] [-d ""] [resource]
#       .e.g,
#       share  -F nfs  -o rw=engineering  -d "home dirs"  /export/home2

share  -F nfs  -o rw=sparc,root=sparc  -d "File System" /
share  -F nfs  -o rw=sparc,root=sparc:sparc1:sparc2  -d "User Directory" /usr

1.第一行 share 是把 / (root) share 給一台叫 sparc 的機器,且權限為可以 rw.
2.第二行同樣是把 /usr 這個目錄 share 給 sparc,sparc1,sparc2 這三台機器,
  權限亦為 rw.

 exp.    share  -F nfs  -o rw=sun2,root=sun2  -d "sun1_home" /export/home
  or      share -F nfs -o rw,anon=0 /export/home 

修改完之後,以 root 的身份執行 shareall 即可.

檢查 /etc/dfs/sharetab 是否編輯成功

solaris NFS file server
1.How to Start and Stop NFS server
  #/etc/init.d/nfs.server start
  #/etc/init.d/nfs.server stop
2.開機自動分享nfs的檔案系統
修改
/etc/dfs/dfstab檔案
#vi /etc/dfs/dfstab
會看到以下畫面,#是註解

#    Place share(1M) commands here for automatic execution
#    on entering init state 3.
#
#    Issue the command 'svcadm enable network/nfs/server' to
#    run the NFS daemon processes and the share commands, after adding
#    the very first entry to this file.
#
#    share [-F fstype] [ -o options] [-d "<text>"] <pathname> [resource]
#    .e.g,
#    share  -F nfs  -o rw=engineering  -d "home dirs"  /export/home2
#   上面有簡單的說明,以下兩行是自己設定的
share -F nfs -o rw,anon=0 -d "nfs_share" /export/home/nfs
share -F nfs -o ro,anon=0 -d "mp3_share" /export/home/samba

3.開機後手動分享檔案的方法
#share -F nfs -o rw,anon=0 -d "nfs_share" /export/home/nfs
#shareall
這樣就可以將檔案分享出去了

4.mount 已經分享的NFS檔案系統
#mount -F nfs ipaddress:/patch mount point
example:
#mount -F nfs 10.0.0.1:/export/home /mnt

4.取消分享的方法
#unshare -F nfs /mnt
取消所有的分享
#unshareall

5.查看分享了哪些檔案
查看server本身有哪些分享

#share
查看別台server 有哪些分享
#dfshares -F nfs ip address or hostname
example
#dfshares -F nfs 192.168.11.200
