Github登录不上去解决办法（win10）

1、win10系统中：

修改hosts文件-解析dns。文件位置：

<pre style="margin: 0px; padding: 0px; overflow: auto; overflow-wrap: break-word; font-family: "Courier New" !important; font-size: 12px !important; white-space: pre;">C:\Windows\System32\drivers\etc</pre>

可以用文本打开，添加dns解析：（复制到hosts最后即可）

2、ubuntu系统中：

修改hosts文件，文件位置：(用vim打开在最后添加同上的dns解析)

<pre style="margin: 0px; padding: 0px; overflow: auto; overflow-wrap: break-word; font-family: "Courier New" !important; font-size: 12px !important; white-space: pre;">sudo vim /etc/hosts</pre>

3、win10更新dns：

<pre style="margin: 0px; padding: 0px; overflow: auto; overflow-wrap: break-word; font-family: "Courier New" !important; font-size: 12px !important; white-space: pre;">ipconfig /flushdns</pre>

4、ubuntu更新dns：

<pre style="margin: 0px; padding: 0px; overflow: auto; overflow-wrap: break-word; font-family: "Courier New" !important; font-size: 12px !important; white-space: pre;">sudo /etc/init.d/dns-clean start</pre>

补充：更新完后重启浏览器。

dns解析服务器IP的获得:

在dns解析网址中输入要解析的域名，点击检索，找TTL值最小的IP，添加进hosts，做为域名解析。
