部署NFS服务端与客户端并测试
NFS 服务端需要安装 rpcbind 和 nfs-utils
NFS 客户端只需要安装 nfs-utils
nfs端口号2049
RPC端口号111
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
服务端：使用yum安装#yum install -y nfs-utils rpcbind
客户端：使用yum安装#yum install -y nfs-utils
服务端创建开放目录与授权：

配置NFS存储共享⽬录并授权

mkdir -p /opt/nfs/rancher && chmod -R 777 /opt/nfs/rancher

开放nfs共享目录权限

echo "/opt/nfs/rancher 192.168.xxx.xxx(rw,sync,insecure,no_subtree_check,no_root_squash)" >> /etc/exports

加载nfs开放目录并查看

exportfs -ar && more /etc/exports
服务端启动：

启动 RPC 服务

systemctl start rpcbind

启动 NFS 服务

systemctl start nfs-server

客户端创建挂载点并将开放目录挂载
showmount -e 服务端地址
