解决GitHub加载和下载慢问题

1. 修改HOSTS文件：

在“C:\Windows\System32\drivers\etc” 下的HOSTS文件，添加以下地址：

# GitHub Start
52.74.223.119     github.com
192.30.253.119    gist.github.com
54.169.195.247    api.github.com
185.199.111.153   assets-cdn.github.com
151.101.76.133    raw.githubusercontent.com
151.101.108.133   user-images.githubusercontent.com
151.101.76.133    gist.githubusercontent.com
151.101.76.133    cloud.githubusercontent.com
151.101.76.133    camo.githubusercontent.com
151.101.76.133    avatars0.githubusercontent.com
151.101.76.133    avatars1.githubusercontent.com
151.101.76.133    avatars2.githubusercontent.com
151.101.76.133    avatars3.githubusercontent.com
151.101.76.133    avatars4.githubusercontent.com
151.101.76.133    avatars5.githubusercontent.com
151.101.76.133    avatars6.githubusercontent.com
151.101.76.133    avatars7.githubusercontent.com
151.101.76.133    avatars8.githubusercontent.com
# GitHub End

2. 刷新DNS
ipconfig /flushdns
 
CentOS :

sudo vi /etc/hosts
