NFS服务自动搭建及挂载脚本

一、写脚本的动机

由于最近老是搭建NFS,虽然不复杂，但是很繁琐。安装服务、修改配置文件、手动挂载、写入开机自动挂载等于是就写了一个脚本

二、脚本说明及审明

作用：该脚本主要实现NFS自动安装，客户端的自动挂载、写入开机自动挂载
使用环境：centos6、nfs客户端的个数为2个
参数：nfs服务端ip、第1个客户端IP、第2个客户端IP、第1个客户端密码、第2个客户端密码、NFS目录
申明：该脚本在本人的服务器上跑是正常的，如果你要用于自己的环境需先测试，该脚本完全处于作者自己爱好，使用脚本请三思。脚本中的参数请根据实际的情况填写，脚本内容如下：

#!/bin/bash
