nginx重写 index.php/ 为 i/

Question

下面是我的CentOs服务器的nginx配置文件，现在已经正常可以访问index.php，但现在有一个重写需求，就是我输入23.abc.com/i/abc的时候重写为到23.abc.com/index.php/abc，即把index.php以i代替。请问在下面的基础上，应该如何修改？
server {

    listen       80;
    server_name  23.abc.com;

    index index.html index.htm index.php;
    root  /home/wwwroot/test/;


            location ~ \.php($|/) {
                    set  $script     $uri;
                    set  $path_info  "";
                    if ($uri ~ "^(.+\.php)(/.+)") {
                            set  $script     $1;
                            set  $path_info  $2;
                    }


                    #fastcgi_pass   127.0.0.1:9000;
                    fastcgi_pass unix:/tmp/php-cgi.sock;
                    fastcgi_index  index.php;
                    include fcgi.conf;
                    fastcgi_param  SCRIPT_FILENAME    $document_root$script;
                    fastcgi_param  SCRIPT_NAME        $script;
                    fastcgi_param  PATH_INFO          $path_info;

            }

    }
