阿里云及各种云无法连接github的解决方案

造成这个情况的原因我们不得而知，只能想办法尽量保障生产环境别出错。。。

对，这个方案就是修改系统host，hosts 文件在每个系统的位置不一，详情如下：

• Windows 系统：C:\Windows\System32\drivers\etc\hosts
• Linux 系统：/etc/hosts
• Mac（苹果电脑）系统：/etc/hosts
• Android（安卓）系统：/system/etc/hosts
• iPhone（iOS）系统：/etc/hosts

然后将下面这些数据拷贝到自己电脑的hosts文件，再激活生效就可以了

大部分情况下是直接生效，如未生效可尝试下面的办法，刷新 DNS：

• Windows：在 CMD 窗口输入：ipconfig /flushdns
• Linux 命令：sudo nscd restart，如报错则须安装：sudo apt install nscd 或 sudo /etc/init.d/nscd restart
• Mac 命令：sudo killall -HUP mDNSResponder
