Ubuntu下git clone加速方法

• 环境 ：Ubuntu 20 in Vmare
• 问题：git clone复制github仓库时命令速度慢、无法访问
• 解决：修改host文件

Step1 获取github IP地址

nslookup github.com

github.com

Server:         127.0.0.53
Address:        127.0.0.53#53

Non-authoritative answer:
Name:   github.com
Address: 20.205.243.166
Name:   github.com
Address: 2404:6800:4000::c01e:ff70
Name:   github.com
Address: 2404:6800:4000::c01e:ff71```

Step2 获取github.global.ssl.fastly.net的IP地址

nslookup github.global.ssl.fastly.net

Server:         127.0.0.53
Address:        127.0.0.53#53

Non-authoritative answer:
Name:   github.global.ssl.fastly.net
Address: 104.244.46.21
Name:   github.global.ssl.fastly.net
Address: 2001::68f4:2e3f

Step3 访问host文件并修改

sudo vim /etc/hosts

在文件最后一行加上

#github
104.244.46.21 http://github.global.ssl.fastly.net
104.244.46.21 https://github.global.ssl.fastly.net

20.205.243.166 http://github.com
20.205.243.166 https://github.com

Step4 刷新缓存

sudo /etc/init.d/network-manager restart

---

即可解决github clone速度慢的问题

其他方法

1. 使用cgit工具

sudo apt-get install cgit
cgit clone ...... 

2. 添加gitclone.com前缀

例如：

git clone https://gitclone.com/github.com/tendermint/tendermint.git

可以设置git参数 实现自动替换

git config --global url."https://gitclone.com/".insteadOf https:
