Linux 系统 在git 上的加速

原因：  访问github受限.

解决方案：通过设置github.global.ssl.fastly.net的ip，修改DNS来提高速度

 

先使用nslookup查看域名的ip

[root@VM_0_3_centos projects]# nslookup github.global.ssl.fastly.net
Server:		183.60.83.19
Address:	183.60.83.19#53

Non-authoritative answer:
Name:	github.global.ssl.fastly.net
Address: 151.101.109.194

[root@VM_0_3_centos projects]# nslookup github.com
Server:		183.60.83.19
Address:	183.60.83.19#53

Non-authoritative answer:
Name:	github.com
Address: 13.250.177.223

vim /etc/hosts
修改host，加入下面代码：

151.101.229.194 github.global.ssl.fastly.net
13.250.177.223 github.com

刷新网络设置

[root@VM_0_3_centos projects]# sudo /etc/init.d/network restart
