Nginx+CI出现404错误
最近刚学ci框架，做了个简单的项目，在本地搭服务器的环境都调通了，但是部署到远程服务器时：
http://example.com/(index.php)/ 可以访问（为配置的默认controller-class）
http://example.com/(index.php)/[controller-class]/[controller-method] 不可以访问（提示404错误！）
最后百度原因：
对于/index.php/abc这种url，Apache和Lighttpd会按”index.php?abc”来解释，而nginx会认为是请求名字是“index.php”的目录下的abc文件的内容。所以CI在nginx下不配置rewrite是无法运行的，而在Apache和Lighttpd则正常。
解决方案(要点加粗，重点标红)：
