nuc977 配置nfs

ubuntu16.04

安装nfs服务

如果用: apt-get install nfs-kernel-server portmap安装后会自动运行

 

打开/etc/exports文件，在末尾加入：

/ * 保存(注意/ * 之间有空格)

注:/etc/exports为NFS服务器的配置文件,"/ *"是挂载根目录下的所有文件

 

执行下面重启NFS服务

/etc/init.d/nfs-kernel-server restart

 

 

注：nfs允许挂载的目录及权限，在文件/etc/exports中进行定义，各字段含义如下：

/home/ *(rw,sync,no_root_squash)

/home/：要共享的目录

* ：允许所有的网段访问

rw ：读写权限

sync：资料同步写入内在和硬盘

no_root_squash：nfs客户端共享目录使用者权限

 

本机挂载测试

取消挂载

umount /mnt
