在Anolis 8.6系统上搭建nfs服务器，在客户端挂载时出现如下错误：
rpc mount export: RPC: Unable to receive; errno = Connection refused

复现步骤
1. yum -y install nfs-utils rpcbind 
2. vim /etc/exports
   写入如下内容：/mnt/back *(rw,sync,no_root_squash)
3. mkdir -p /mng/back
4.  systemctl start rpcbind；systemctl enable rpcbind;systemctl start nfs-server
    systemctl stop firewalld  
5. 在客户端执行挂载动作或在服务端执行showmount -e，出现如下错误：
    [root@localhost ~]# showmount -e
     rpc mount export: RPC: Unable to receive; errno = Connection refused
