防火墙也放行了相关服务：
[root@anolis etc]# firewall-cmd --list-all
public (active)
target: default
icmp-block-inversion: no
interfaces: ens32
sources:
services: cockpit dhcpv6-client mountd nfs rpc-bind ssh
ports: 10050/tcp
protocols:

显示共享目前却始终报如下错误：
[root@anolis etc]# showmount -e
rpc mount export: RPC: Unable to receive; errno = Connection refused
请问，如何这种问题如何解决？
