无法安装“程序未注册错误”

Question

我正在尝试mount一个NFS卷，但没有成功。我将Linux7.3作为一个VM运行。我在/var/log/messages中没有看到任何错误消息。以下是我到目前为止所采取的步骤：

[root@backup ~]# showmount -e 192.168.1.212

rpcinfo

[root@backup ~]# rpcinfo -p 192.168.1.212 | cut -c30- | sort -u    
portmapper
service
ypbind

我不明白为什么rpcinfo缺少NFS？还有其他命令我可以试着解决这个问题吗？

Answer 1

消息“程序未注册”表示服务器上存在问题，至少我假设192.168.1.212是您的服务器，因为不需要向显示挂载添加地址以获取有关本地主机的信息。

因此，您应该确保NFS服务器在服务器上运行。开始于

rpcinfo 192.168.1.212

如果可能，请验证这些进程是否正在服务器上运行。

Answer 2

确保nfs-mountd服务正在运行：

systemctl status nfs-mountd

根据需要重新启动nfs-服务器服务
