CodeIgniter在nginx下404 not found

server {

        listen       ;
        server_name  test.platform;
        charset utf8;
        root  /data/www/platform/trunk;

        location / {
            index index.html index.php;
        }   

         location ~ \.php($|/) {

            fastcgi_pass   127.0.0.1:;
            fastcgi_index  index.php;
            fastcgi_split_path_info ^(.+\.php)(.*)$;
            fastcgi_param   PATH_INFO $fastcgi_path_info;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            fastcgi_param    PATH_TRANSLATED    $document_root$fastcgi_path_info;
            include        fastcgi_params;
        }   

        if (!-e $request_filename) {
            rewrite ^/(.*)$ /index.php/$ last;
            break;
        }   

        access_log  /usr/local/nginx/logs/test.platform.access.log;
        error_log  /usr/local/nginx/logs/test.platform.error.log;
    }

修改nginx的server如上面，就ok了，该问题捯饬了一天，才搞定；

需要注意的地方：

 location ~ \.php($|/) {

一开始我的配置为：

 location ~ \.php$ {  所以一直没有搞成功，这个问题折腾了很久，特此说明一下。
