Mac 打不开github解决方案

序言

github 时有打不开的情况，为此很是烦恼，这里分享一下如何解决这种问题，其实问题的本质是在访问github网页时无法通过github.com的二级域名进行动态域名解析。

解决方案

手动配置静态文件hosts，将该域名和IP的映射关系添加到静态文件中，在访问地址时会优先通过Hosts文件进行域名解析。

解决步骤

1. 找到github.com域名对应的IP地址，输入网址：站长工具Dns查询找出最快的IP地址

2. 打开终端，输入 sudo vim /etc/hosts

3. 追加或者更改 本地hosts文件，本次结合命令 i --> 添加ip --> esc --> :wq （i: 进入编辑模式，esc: 退出编辑模式，:wq 保存文件并退出）

   Host Database

   localhost is used to configure the loopback interface

   when the system is booting. Do not change this entry.
