vagrant打包，释放包空间_vagrant package 很大-优快云博客

前言

今天准备打包自己的虚拟机，这时发现了个问题，虚拟机比之前我按时的时候增加了5个G，考虑到以后其他人还能会使用这个开发环境。
所以现在首要问题是搞清楚虚拟机为什么会占用如此多的空间并解决空间占用问题？

问题描述

虚拟机从一开安装的500MB，运行了半年多，变成了5个多G，是因为虚拟机系统日志，缓存之类的文件导致了虚拟机占用空间越来越大。

解决办法

登录虚拟机，新建purge.sh文件，并且增加执行权限x

vagrant@vagrant:~$ sudo touch purge.sh
vagrant@vagrant:~$ sudo chmod a+x purge.sh

使用vi命令打开purge.sh 文件添加如下代码：

#!/bin/sh
