ubuntu挂载到A53开发板步骤介绍及脚本原码实现

一、ubuntu搭建nfs服务器

开发板 访问 ubuntu的目录 1.nfs服务安装： #sudo apt-get install nfs-kernel-server nfs-common 2.工作路径配置： #sudo gedit /etc/exports,加上以下语句： / *(rw,sync,no_root_squash) 3.重启服务生效： #sudo service nfs-kernel-server restart

二、挂载的实现

启动开发板后会默认进入home目录，将mount_nfs.sh写好的shell脚本拷贝到当前目录（脚本原码给各位官爷们放到了文件的末尾，可自行拷贝），然后执行一下命令：

./mount_nfs.sh Ubuntu的ip /home/share /mnt ///home/share 为要挂载的虚拟机地址 ///mnt 挂载到的开发板目录

齐活，收工！！！ cd /mnt 即可查看挂载目录后的内容啦…

shell脚本原码：

#!/bin/sh #auto get ip udhcpc #config ip netmask gw #ifconfig eth0 172.20.223.123 netmask 255.255.255.0 #route add default gw 172.20.223.254 serverip=$1 serverpath=$2 localpath=$3 echo "usage:./mount_nfs serverip serverpath localpath" if [ -z $serverip ]; then echo "serverip is NULL" exit 1 fi if [ -z $serverpath ]; then echo "serverpath is NULL" exit 1 fi if [ -z $localpath ]; then localpath=/mnt/nfs echo "localpath default /mnt/nfs" fi mount -o nolock,wsize=1024,rsize=1024 $serverip:$serverpath $localpath if [ $? = 0 ]; then echo "nfs mount succeed!!" echo "if you want to umount the serverpath" echo "please input umount like this: umount /mnt" else echo "nfs mount failed,please check and try again!!" fi
