step2. 在/etc/hosts中添加一行如下:

192.30.252.128 github.com

解决方式2：

以root权限执行如下python代码

#!/usr/bin/python
#coding=utf8

import socket

host = 'github.com'

try:
with open('/etc/hosts', 'a+') as fp:
ip = socket.gethostbyname(host)
fp.write(' '.join([ip, host, '\n']))
except BaseException as e:
print(e)
else:
print('sucess')
