Question

我一直在为我运行的网站使用Django，我最近的任务是将数据库移动到外部服务器。我已经配置，安装了MySql-Connector-Python，并将两台服务器配置为相互通信。我遇到了一个奇怪的错误，我看到其他人也有问题。我再问这个问题，因为另一个问题已经过时了。 Django已经改变了自今年早些时候以来关于外部sql db服务器的支持。我目前在Debian上运行Django vs 1.8，使用python 2.7.9，我在使用MySql Vs 5.6运行CentOS的单独服务器上安装了我的Sql DB。

以下是我遇到的错误：

我已经针对这个问题做了很多研究。我遇到的问题是数据是旧的，并且会说像“django还不支持”这样的事情并且已经改变了。我找不到问题的任何线索或答案，这对我在短时间内没有帮助。
