1、修改hosts文件，在终端输入

sudo vi /etc/hosts

在末尾加入你要添加的IP地址和域名，比如

# The following lines are desirable for IPv6 capable hosts
::1     localhost       ip6-localhost   ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
8.8.8.8 XXXXXXXX  XXXXXXXX
127.0.0.1 localhost  localhost
140.82.112.4 github.com
185.199.108.153 assets-cdn.github.com
185.199.109.153 assets-cdn.github.com
185.199.110.153 assets-cdn.github.com
185.199.111.153 assets-cdn.github.com
199.232.69.194 fastly.net
~                                                                                                                                                                   
~                                                                                                                                                                   
~                                                                                                                                                                    
~                                                                                                                                                                   
"/etc/hosts" 14L, 422C

（vi的基本用法是按i改成修改模式，添加完内容以后按ESC，然后按两次ZZ退出vi）

2、刷新DNS缓存
