我正在尝试从我的 OSX 机器上通过 nfs 共享一个目录，以便由 Ubuntu 客户端 (VM) 安装。我感觉我在访问权限方面缺少了一些东西。当我尝试安装 nfs 共享时，我收到一条有关访问被拒绝的错误。我可以在两台机器之间进行 ssh 连接，但使用 nfs 时却没有成功。
OSX ip 是 xxx.xxx.xx.xxx 而 Ubuntu 是 yyy.yyy.yyy.yyy
OSX /etc/导出：
/Users/MichaelHackman/C -alldirs -mapall=501
OSX /etc/hosts.allow：
ALL: yyy.yyy.yyy.yyy
在 Linux 上：
$showmount -e xxx.xxx.xx.xxx
Export list for xxx.xxx.xx.xxx:
/Users/MichaelHackman/C (everyone)
$sudo mkdir -p /nfs/C
$sudo mount -vvvvv xxx.xxx.xx.xxx:/Users/MichaelHackman/C /nfs/C

答案1
如果有人想让它工作，请使用 VMware Fusion 的“共享文件夹”功能，让它变得简单。
