一、修改hosts
1、解决在 Win10没有修改 hosts文件权限问题
WIN + R打开下方框框，输入“C:\Windows\System32\drivers\etc”：
根据下图3步操作，以管理员身份运行：
在弹出终端窗口中依次输入cmd、notepad hosts：
然后就可以任意修改hosts啦
2、在Ubuntu18.04虚拟机中修改hosts
打开终端命令行，输入命令：sudo gedit /etc/hosts，即可打开并编辑hosts文件。
二、修改hosts内容
在打开的hosts文件中添加下面这段“github520代码”（实现自动更新ip）：
# GitHub520 Host Start

三、每次使用前刷新一下DNS
Windows每天使用前都要刷新一下DNS，否则依旧会很慢
（Ubuntu暂时还不清楚）
Windows+X 打开系统命令行（管理员身份）或powershell，
运行ipconfig /flushdns 手动刷新系统DNS缓存。
可爱的界面出来啦
