前端代码什么都看不出来。。

500是代码中有语法错误，应该是admin.php中有语法错误

先对比下本地和Ubuntu 2个环境下的请求是否一致
不过我估计是你本地的环境和Ubuntu下的环境不一致导致的一些语法错误，包括PHP版本和apache(nginx)

后端程序从这几个方面入手：1.返回的数据格式错误 2.程序方面错误 3.服务器方面的错误，

看看php的路径有没有问题?看看返回的数据是不是完整?

建议开启所有错误。
比如代码开启错误提醒：

<?php
error_reporting(E_ALL);
ini_set("display_errors", 1)
?>

然后记得查看PHP的错误日志。
Nginx的错误日志
PHP-FPM的错误日志
有的时候，报了50x的错误。系统不会提示出来。会记录到错误日志里面。自己仔细看看。

服务器环境不同造成的原因居多,Ubuntu的话,检查一下权限吧.另外给楼主提个建议.本地开发的话.最好用vagrant或者docker搭建开发环境.wamp等集成环境用来学习就好
