无法挂载 NFS“程序未注册错误”

我正在尝试mountNFS 卷，但没有成功。我正在将 Linux 7.3 作为虚拟机运行。我在 中没有看到任何错误消息/var/log/messages。这些是我到目前为止所采取的步骤：

我不明白为什么rpcinfo缺少 NFS？我可以尝试使用其他命令来解决此问题吗？

答案1

消息“程序未注册”表明服务器上有问题，至少我假设 192.168.1.212 是您的服务器，因为不需要添加地址到 showmount 来获取有关本地主机的信息。

所以你应该确保服务器上正在运行NFS服务器。从...开始

rpcinfo 192.168.1.212

如果可能的话，验证进程是否正在服务器上运行。

答案2

确保 nfs-mountd 服务正在运行：

systemctl status nfs-mountd

根据需要重新启动 nfs-server 服务
