1.利用nfs设置Linux系统之间的文件共享
2.安装yum install -y nfs-utils rpcbind
2.1服务端客户端都进行安装
3.配置文件修改：/etc/exports
3.1启动服务（顺序不能打乱） /bin/systemctl start rpcbind.service /bin/systemctl start nfs.service
3.2否则出现
4.showmount –e查看一下，看看共享的目录情况（记得创建相应的目录）
4.1查看其他机器的共享情况
5.挂载
mount -t nfs 172.16.254.132：/srv/node/vdd
6.构建ring（脚本）
#!/bin/bash
set -e
echo_green() {
echo -n -e "\033[32m$1\033[0m"
}
echo_green_enter() {
echo -e "\033[32m$1\033[0m"
}
