最近剛學ci框架，做了個簡單的項目，在本地搭伺服器的環境都調通了，但是部署到遠端伺服器時：
http://example.com/(index.php)/ 可以訪問（為配置的預設controller-class）
http://example.com/(index.php)/[controller-class]/[controller-method] 不可以存取（提示404錯誤！）
最後百度原因：
對於/index.php/abc這種url，Apache和Lighttpd會按」index.php?abc」來解釋，而nginx會認為是請求名字是「index.php」的目錄下的abc檔案的內容。所以CI在nginx下不配置rewrite是無法運作的，但在Apache和Lighttpd則正常。
解決方案(要點加粗，重點標紅)：

以上就介紹了Nginx+CI出現404錯誤，包含了面向的內容，希望對PHP教學有興趣的朋友有幫助。
