Mac下Homebrew替换镜像

替换git和homebrew镜像源

一、git加速

1. 查找域名对应的地址
   
   nslookup github.com
   
   nslookup github.global.ssl.fastly.Net

2. 修改hosts文件

   sudo vim /etc/hosts
   # add two lines at the end.
   31.13.66.1 github.global.ssl.fastly.net
   13.229.188.59 github.com
   

3. 刷新DNS缓存（根据你的操作系统选择）

   # Mac
   sudo killall -HUP mDNSResponder
   # linux
   sudo /etc/init.d/networking restart
