主服务器
下载nfs-utils软件包：
1.如果停⽌该服务，启动并启⽤该服务： systemctl enable - now rpcbind
2.要启动 NFS 服务器，并使其在引导时⾃动启动：systemctl enable - now nfs- server
3.配置防火墙，开启服务：
[root@localhost ~]# firewall-cmd --permanent --add-service=nfs
success
[root@localhost ~]# firewall-cmd --permanent --add-service=mo
untd
success
[root@localhost ~]# firewall-cmd --permanent --add-service=rpc-bind
success
[root@localhost ~]# firewll-cmd --reload
[root@localhost ~]# firewall-cmd --list-all
