嵌入式Linux经常使用服务配置之nfs服务配置

安装nfs:

#sudo apt-get install nfs-kernel-serverlinux

Ubuntu 10.10中的已是最新版本了,无需安装this

打开/etc/exports文件,在末尾加入:rest

/home/xgc *(rw,sync,no_root_squash)server

注:nfs容许挂载的目录及权限,在文件/etc/exports中进行定义, 各字段含义以下:ip

/home/xgc:要共享的目录ci

* :容许全部的网段访问get

rw :读写权限同步

sync:资料同步写入内在和硬盘it

no_root_squash:nfs客户端共享目录使用者权限io

重启服务:

#sudo /etc/init.d/portmap restart <---重启portmap,很重要

#sudo /etc/init.d/nfs-kernel-server restart <---重启nfs服务

#showmount -e <---显示共享出的目录

注:nfs是一个RPC程序,使用它前,须要映射好端口,经过portmap设定

命令执行状况以下:

xgc@xgc-VirtualBox:~$ sudo /etc/init.d/portmap restart

Rather than invoking init scripts through /etc/init.d, use the service(8)

utility, e.g. service portmap restart

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 474

xgc@xgc-VirtualBox:~$ sudo /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...

exportfs: /etc/exports [1]: Neither 'subtree_check' or 'no_subtree_check' specified for export "*:/home/xgc".

Assuming default behaviour ('no_subtree_check').

NOTE: this default has changed since nfs-utils version 1.0.x

[ OK ]

* Starting NFS kernel daemon [ OK ]

xgc@xgc-VirtualBox:~$ showmount -e

Export list for xgc-VirtualBox:

/home/xgc *

如今能够在本机上试一下:

#sudo mount -t nfs localhost:/home/xgc /mnt

注:localhost为本机linux的IP地址

这样就把共享目录挂到了/mnt目录,取消挂载用:

#sudo umount /mnt

若是用在嵌入式设备上挂载,要加上参数-o nolock
