【RHCE】NFS 实验

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：

复制代码

success
[root@localhost ~]# firewall-cmd --permanent --add-service=mo

[root@localhost ~]# firewall-cmd --permanent --add-service=rpc-bind
