#master节点安装nfs
yum -y install nfs-utils
#创建nfs目录
mkdir -p /nfs/data/{mqdata,esmaster,esdata}
#修改权限
chmod -R 777 /nfs/data/

#编辑export文件
vim /etc/exports

粘贴如下内容：

#查看生效
exportfs

#启动rpcbind、nfs服务
systemctl restart rpcbind && systemctl enable rpcbind
systemctl restart nfs && systemctl enable nfs

#查看 RPC 服务的注册状况
rpcinfo -p localhost

#showmount测试，这里的ip输入master节点的局域网ip
showmount -e <your ip>
