#这里我使用单独服务器进行演示，实际上顺便使用一台服务器安装nfs都可以 (建议和kubernetes集群分开，找单独一台机器)
yum install nfs-utils -y rpcbind
#接下来设置nfs存储目录
mkdir /data/k8s-volume
chmod 755 /data/k8s-volume/
#编辑nfs配置文件
cat /etc/exports
/data/k8s-volume  *(rw,no_root_squash,sync)
#存储目录，*允许所有人连接，rw读写权限，sync文件同时写入硬盘及内存，no_root_squash 使用者root用户自动修改为普通用户
接下来启动rpcbind
systemctl start rpcbind
systemctl enable rpcbind
systemctl status rpcbind
