实现步骤:
1.服务器端:sudo apt-get install portmap
2.服务器端:sudo apt-get install nfs-kernel-server
3.客户端:sudo apt-get install nfs-common
4.服务器端配置:sudo gedit /etc/exports
添加:/home *(rw,sync,no_root_squash)
(共享目录) (允许IP)
(rw权限是可擦写,还有ro只读,
sync代表数据会同步写入到内存与硬盘中,async则代表数据会先暂存于内存当中,而非直接写入硬盘,
开放客户端使用root身份来操作服务器的文件系统,那么开no_root_squash才行,root_squash不允许)
5.服务器端启动:sudo /etc/init.d/portmap restart
6.服务器端启动:sudo /etc/init.d/nfs-kernel-server restart
7.arm板连接时:主机:sudo ifconfig eth0 192.168.9.131 netmask 255.255.255.0
arm板:ifconfig eth0 192.168.9.102 netmask 255.255.255.0
8.arm板上mount: mount -o nolock 192.168.9.131:/home/ /mnt/fat/
(主机IP和共享目录) (arm板目录)
mount上之后arm板上文件自动同步
(
1.出现问题:
reason given by server: Permission denied
解决:
服务器端启动一定要sudo启动,不然启动失败,服务拒绝
2.出现问题:
svc: failed to register lockdv1 RPC service (errno 111).
lockd_up: makesock failed, error=-111
mount: mounting 192.168.1.101:/home/share on /mnt/hosts failed: Connection refused
则改成:
mount -t nfs -o nolock 192.168.1.101:/home/share /mnt/hosts
3.出现问题:
mount: mounting 192.168.1.101:/home/share on /mnt/hosts failed: Device or resource busy
解决:
mount上之后在进行mount命令会出现此提示,设备正在运行,不用再次mount
如果想再次mount可以先umount /mnt/hosts

NFS服务器安装配置实现Ubuntu 12.04与ARM开发板文件共享
